Voltage relay control relay switch, when therefore motor component operation also no longer needs to startWhen moment of torsion, described relay switch stops start-up capacitance. Voltage relay is according to the control across relayVoltage processed changes the configuration of relay switch, disconnects or closing relay switch.
In the time that control voltage exceedes threshold value, relay relay switch and start-up capacitance are brokenOpen.
The present invention also relates in particular to a kind of electric system and one of the compressor for refrigeration applicationStart the method for this electric system.
Background technology
Fig. 1 roughly illustrates compressor electric motor well known in the prior art. Voltage relay 6 based onAcross the voltage of auxiliary winding carry out control relay switch 7 and enable thus or inactive start-up capacitance CS and/Or auxiliary winding 5.
In the time that electric power is supplied to motor at first, low across the voltage of auxiliary winding, therefore voltage relay placeNon-initiate mode and because of but relay switch conducting, closed configure, as shown in Figure 1.In this relay configuration, auxiliary winding connects via start-up capacitance and starting torque is provided.
As shown in Figure 2, in the time that speed increases (abscissa), across voltage (the vertical seat of auxiliary windingMark) increase. In the time that voltage arrives disconnection threshold value, voltage relay moves to relay switch non-Relay switch configuration conducting, open circuit. This has disconnected start-up capacitance CS, is being not activatedIn the situation of electric capacity, continue the operation of motor, auxiliary winding drives by operation capacitor C R, orNot moving in the motor of electric capacity, auxiliary winding is disconnected simply.
POL place after startup, operation electric capacity improves the efficiency of motor, and this is to use operation electricityThe reason of holding. Operation electric capacity normally start-up capacitance 1/5th to 1/10th.
By definition herein, we will " enable " to describe to control at following use term and continueElectric switch moves to the activity of the relay of the position that causes start-up capacitance disconnection, uses term" stop using " and describe control relay switch and move to the continuing of position of the connection that causes start-up capacitanceThe activity of electrical equipment.
For the reason of stability and for fear of enabling repeatedly and stopping using, relay is designedBecome to have hysteresis, thus, that controls voltage enables current potential higher than the inactive electricity of controlling voltagePosition. Controlling the hysteresis of voltage is shown by four arrows that are connected and form closed-loop path in Fig. 3Go out.
If motor overload, if the load of motor is higher than ultimate torque (breakdownTorque or breakaway torque), will drop to the inactive control electricity of relay across the voltage of auxiliary windingPress following and start-up capacitance is connected. This is shown by some arrow upwards under the low speed in Fig. 3Go out.
The reset of start-up capacitance provides the moment of torsion increasing to overcome described load. Therefore, motor speedDegree increase and therefore increase across the voltage of auxiliary winding until arrive control voltage enable current potential and startupTill therefore electric capacity disconnect. This order repeats self, and relay is by the machinery depending on motorLoad is enabled repeatedly and is stopped using, for example, with the frequency in the scope of 1Hz.
Due to repeatedly enabling and stop using, it is energy that auxiliary winding and start-up capacitance become under overload situationsEnough runnings. Typically, motor is not designed to obtain this increase on the longer time periodPower, and electrical system becomes overload. Especially, motor winding and cable etc. are in by excessivelyThe risk damaged of heating in.
Summary of the invention
One of object of embodiments of the invention is to provide the motor that comprises electric power system and motor componentSystem and for the independently electric power system of motor component, they have avoided repeatedly opening of relayWith with stop using above-mentioned defect.
According to first aspect, this object is realized by an electric system, in described electric system,Relay is located so that with respect to relay switch relay switch is between closure and open-loop configurationMotion control voltage depend on across the state of the voltage of auxiliary winding and control voltage do not rely on acrossBetween the state of the voltage of auxiliary winding, change.
Because the closure of relay switch is independent of the voltage across auxiliary winding, so it is independent to control voltageIn the spinner velocity (RPM) of electric system, therefore not shadow of the heavy duty of electric system or heavy loadRing the motion of relay switch. So relay switch keeps open-loop configuration until electric system is completeTill contract fully, the above-mentioned defect of repeatedly enabling and stopping using of relay is avoided.
In practice, start-up capacitance can be between phase wire connections and first node, auxiliary windingCan be between Section Point and zero line connector, and relay switch can be positioned at first nodeAnd between Section Point. By this way, relay switch can be in closed configuration by electric current fromFirst node is conducting to Section Point, and in open-loop configuration, prevents at first node and Section PointBetween conducting, this will provide following characteristics: the motion of relay switch control voltage depend onAcross the state of the voltage of auxiliary winding with control voltage and do not rely between the state across the voltage of auxiliary windingChange.
Relay can be inserted between first node and zero line connector, so that proper relay is openedWhen pass is in open-circuit condition, relay switch separates relay with auxiliary winding thus effectively.
At this, term " node " covered as in the claims further regulation two realitiesAny tie point between body or electric component, that is, and the joint between two entities or electric componentPoint is cable, wire or the electric conductor that connects described two entities simply.
Especially, electric system can be for drive compression machine. At this, " compression is dynamo-electric for termMachine " cover the motor for the compressor of any kind, for example compressor in refrigeration system.Electric system also can be for other objects.
At this, the voltage of term " control voltage " Coverage Control relay. Control voltage and threshold valueCompare, and depend on control voltage be higher than threshold value or lower than threshold value, relay switch is by continuingElectrical equipment moves to open circuit or closed configuration, that is, controlling voltage is the voltage across relay.
Relay can be the electromechanical relay having by the armature moving from the magnetic field of coil.Once voltage arrives threshold value, magnetic field is enough to mobile this armature therefore mobile relay switch, orPerson, relay can be electronic relay.
Typically, electric system will comprise two parallel circuit, i.e. main circuit and secondary circuit. InstituteState circuit extends concurrently between phase wire connections and zero line connector.
Main circuit comprises the main winding for drive rotor in course of normal operation. Secondary circuit comprisesStart-up capacitance CS between phase wire connections and above-mentioned first node, first node andRelay switch between two nodes and for drive the auxiliary winding of rotor in start-up course. SecondaryWinding is between Section Point and zero line connector.
At first, before electric system is connected, in system, the voltage of any position is zero, correspondingGround, relay is deactivated, and relay switch is in the close position. In the time that electric system is connected,Voltage on auxiliary winding increases by the RPM that increases electric system, due to closed relaySwitch, the control voltage on relay is in fact corresponding to the voltage on auxiliary winding. Work as auxiliary windingOn voltage arrive when threshold value, relay is enabled and relay switch, relay is with secondary thusWinding separates, and therefore controls voltage and is no longer dependent on the voltage across auxiliary winding. In order to ensure stableTransfer relay switch, electric system can comprise rectifier, described rectifier will be hereinafter byDescribe in further detail. This rectifier is the one-way conduction providing from auxiliary winding to relay, due toThis one-way conduction, controls voltage and will on the half period at AC signal, depend on the electricity on auxiliary windingPress, and do not rely on the voltage on auxiliary winding on second half cycle of AC signal.
In addition, electric system can comprise the operation electricity between Section Point and phase wire connectionsHold.
PTC can be inserted between Section Point and first node, with relay switch alsoConnection. Thus, PTC forms the divider of relay.
In the time that electric system starts, relay switch is closed, and therefore PTC is bypassed. CorrespondingGround, as long as relay switch closure, PTC just keeps no power or does not generate heat.
Along with electric system accelerates until nominal speed increases until this voltage across the voltage of auxiliary windingTill arriving the high potential of the stable state under nominal speed. At this moment, relay disconnects relaySwitch, the PTC of energising has taken over the conducting to auxiliary winding not yet. Therefore, though relay openPass is disconnected, and voltage relay also can be supplied with the high voltage from parafacies constantly. Due toThe current On current of PTC, so it starts heating, after several seconds, it changes over high ohmResistance mode. This is by the conducting finishing in fact by PTC.
Due to PTC, the duration that auxiliary winding is powered by start-up capacitance increases, and this PTC carriesFor with the delay of the disconnection of start-up capacitance. In the time that PTC heats up, resistance increases and PTC no longer willStart-up capacitance is connected to auxiliary winding.
In addition, electric system can comprise discharge cock, described discharge cock at electric current excessive and because ofInactive motor component in the situation of this excess Temperature. If electric system comprises interior discharge cock,PTC becomes no power or no longer heating in the time that discharge cock is activated. Thus, PTC be secondary aroundWhether group provides electric power and still disconnects regardless of relay switch. PTC can depend on its temperatureFor example change being less than the resistance of 10 ohm and being greater than between the resistance of 50000 ohm.
Enabling conventionally of discharge cock caused by the overload of electric system. In the time that this overload occurs,Relay switch will normally disconnect, and due to separating of the present invention and relay and winding, continuesElectric switch will remain open, and electric system can not generate starting torque via start-up capacitance.But, in the time that discharge cock disconnects, do not have electric current will flow through PTC, therefore PTC is by cooling.
In the time that discharge cock disconnects, PTC becomes cold or temperature is low. When discharge cock againWhen closed, parafacies can be by start-up capacitance by being that cold PTC powers at present. This will be formed onThe instantaneous pressure drop of the 3rd Nodes, resets relay. Thus, electric system is prepared via openingConnection between dynamic condenser and the auxiliary winding on closed relay switch and normally being started.
Electric system can also comprise the bleeder resistance between first node and phase wire connectionsDevice. Due to this bleeder resistor, start-up capacitance discharges, and the life-span of electric capacity can be increased.
The electric bridge with the first rectifier can be provided in the direction from Section Point to relayOne-way conduction.
Bleeder resistor can be between first node and phase wire connections. Bleeder resistor is openingIt when dynamic condenser does not connect, is start-up capacitance electric discharge. Have and be greater than 10000 ohm or be even greater thanThe resistor of the resistance of 80000 ohm can be suitable.
In another embodiment or additionally, electric system can be included in phase wire connections andThe resistor extending between three nodes, described the 3rd node be positioned at the first rectifier and relay itBetween. Resistor can be the form of PTC, and this PTC will become high ohm in the time that it heats up, byThis stops in fact the conducting of resistor.
Voltage relay can be the type that comprises armature, and this armature is by means of the magnetic being provided by coilField is mechanically moved.
Especially, electric system can be formed for the building block of the compressor of refrigeration system.
In second aspect, the invention provides one be used to motor component power supply (for example forForm compressor electric motor) electric power system. Electric power system for motor component be to there is rotorKind, described rotor adapt to by be connected to for motor component is connected to Monophase electric power supply withZero line connector and phase wire connections between main winding drive, and adapt to by auxiliary windingHelp to start, described auxiliary winding is via the startup electricity that the single-phase phase shift of supplying with from electric power is providedHold power supply, described electric power system comprises voltage relay, and described voltage relay can for controllingBe connected to the relay switch of motor component, to make it exceed threshold at the control voltage across relayThe auxiliary winding of inactive motor component when value, its repeat circuit is located with respect to relay switch, so thatObtaining the switching in control voltage of relay switch between closed configuration and open-loop configuration depends on across instituteThe state of the voltage of the auxiliary winding of the motor component connecting and control that voltage do not rely on across auxiliary windingBetween the state of voltage, change.
In the third aspect, the invention provides a kind of method of controlling monophase machine, this monophase machineBe for example the compressor electric motor for refrigeration system, this monophase machine has rotor, and described rotor is suitableBe assigned in by the zero line connector being connected to for motor being connected to Monophase electric power supply and be connected with phase lineMain winding between part drives, and adapts to by the help of auxiliary winding and start, described auxiliary windingVia the start-up capacitance power supply that the single-phase phase shift of supplying with from electric power is provided, described method comprises baseOpen in control voltage mobile relay between closed configuration and open-loop configuration of controlling between nodeClose the step of the start-up capacitance of also stopping using thus, wherein relay switch is arranged with respect to controlling node,Depend on to make relay switch switching between closed configuration and open-loop configuration control voltageAcross the state of the voltage of auxiliary winding with control voltage and do not rely between the state across the voltage of auxiliary windingChange.
