Below the operation principle of present embodiment is done the following description.
1, under the non operating state, plug, seat all are in below the safe voltage.
Normally open by intelligence control system can disconnect socket and connect with the forceful electric power of charger with battery, plug.In the plug only intelligence control system have the 24V direct voltage.
2, only connect when reliable when charge connector, the side allows battery to connect charger and also allows the charger charging, and can realize combined floodgate and separating brake function under the normal condition.
When charging plug connects with socket, because the light current utmost point contact pin a5 of intelligence control system is the shortest, so have only after charge connector is inserted into the also promptly reliable connection in position, intelligence control system allows charger to connect charge connector and allows battery to connect connector, has only when charger and battery all with after the charge connector connection can allow charger to charge.
Allow the operation principle of charger connection charge connector as follows:
After charge connector connects reliably, two light current utmost point contact pin a5 that are inserted in the mutual conduction light current utmost point jack will have one to allow the signal of closing operation to make that No. 13 terminals and No. 14 terminals of DC24V relay MY2J are that the drive coil end is loaded with direct current 24V voltage, No. 12 terminals of DC24V relay MY2J are loaded into the 220V alternating voltage on No. 8 terminals by first normally-closed contact, make when switch knob switch S B1 presses, the combined floodgate performance element U1 of the motor-operating mechanism of circuit breaker has the driven motor-operating mechanism to close a floodgate, thereby realizes closing function.
The connection principle of battery and connector is also similar.Combined floodgate principle under the normal condition also as above.Separating brake principle under the normal condition then is: when pressing opening button switch S B2, the 220V alternating voltage will be loaded into the separating brake performance element U2 of the motor-operating mechanism of circuit breaker, thereby realize the separating brake function under the normal condition.
If 3 have people mistake that charge connector is extracted or charge connector is unexpected throws off, the loop that connects that can take the lead in cutting off charger and battery is responded in the control of intelligent charge connector, and issuable electric arc is to personnel's injury when preventing that charge connector from extracting.
When charge connector is in normal combined floodgate charged state, the people is for extracting in charging plug or the charging plug accidental process, can cause the light current utmost point contact pin a5 of charge connector to take the lead in disconnecting the shortest, make DC24V relay MY2J coil losing electricity, the 220V alternating voltage will be loaded into separating brake performance element U2 by No. 1 terminal of relay, No. 15 terminal DK1-14 and No. 11 terminal DK1-11 of the second auxiliary contact C2, so just can realize carrying out in advance automatically sub-switching operation.No. 15 terminal DK1-14 behind the separating brake on the second auxiliary contact C2 and No. 11 terminal DK1-11 disconnect, so just can be simultaneously being added in the 220VAC disconnection that separating brake performance element U2 holds, in order to avoid switching winding is long charged and fragile during the circuit breaker normally open.
4, when having a power failure, intelligence control system should be able to be cut off the loop that connects of charger and battery automatically, to guarantee safe or guarantee safety when sending a telegram here once more.
Intelligence control system should be set up stand-by power supply so that guarantee also can operate as normal when having a power failure.Under no stand-by power supply situation, in charging process, meet and have a power failure, circuit breaker can not disconnect voluntarily, circuit breaker will keep "on" position, at this moment, No. 15 terminal DK1-14 and No. 11 terminal DK1-11 on the second auxiliary contact C2 are conducting state, relay MY2J is in " normally open ", be No. 9 terminals and No. 1 terminal conducting that is connected No. 15 terminal DK1-14 of relay, sending a telegram here in a flash once more, utilize the normally open of relay MY2J, 220VAC No. 1 terminal and No. 15 terminal DK1-14 by relay MY2J are loaded into separating brake performance element U2 end, just can realize the automatic brake separating function, No. 15 terminal DK1-14 and No. 11 terminal DK1-11 disconnect behind the separating brake simultaneously, with the 220VAC disconnection of separating brake performance element U2 end.Promptly can realize closing function again if press combined floodgate switch S B1 again.So just can play the effect of protection charge circuit and personal safety, prevent that contingency from taking place.
Present embodiment is applied to * * * the demonstration charging station, this charging station charger capacity is: 600V, two of 100A.Through being big bus car charging 2-3 hour nearly 1 year every day of using, about charging current DC75A, this intelligent electric electrical automobile fault do not occur with charge connector and effectively ensured operating personnel's safety in actual charging operations.And the connector of present embodiment smoothly by the test of Abnormal Summer High Temperature in this year, does not break down yet.
This intelligent electric electrical automobile is as follows with the summary of benefits of charge connector:
1, Effective Raise processing safety;
2, practical reliable, fault rate is extremely low;
3, connector adopts fine thread, and both waterproof also can have time enough to cut off the forceful electric power loop by control loop when back-outing by force also so that more laborsaving when inserting;
4, during rated current, the caloric value of connector is significantly less than other products. Market purchasing * * * * charge connector that company provides in direct current 40A situation, temperature soup hand after a few minutes, and the connector of the said goods 3 hours temperature of trickle charge in direct current 80A situation are no more than 40 ℃.
