The primary side of intrinsic safety control transformer that exchanges behind the 36V power connection of the A3 of this controller essential safety high-low pressure feeder equipment switch operated from a distance controller, A5 pin and feeding switch gets electricly, and just there is the output of the 15V of interchange voltage at a of secondary side, b two ends after the rectifier bridge rectification, and the dc terminal of rectifier bridge has the output of direct current 12V voltage; The output current that 100 milliamperes of rated current are just arranged after metallic resistance R1 current limliting gives that pulse control on the pulse power supply circuit is closed a floodgate and separating brake circuit, pulse control reset circuit and signal feedback indicating circuit provide due working power voltage (direct current 12V), and pulse forward trigger pip power supply is that the secondary side b end by transformer KB extracts; Be modulated to voltage available after the socket A1 pin output of this controller through adjustable resistance; Join with an end of No. 1 heart yearn of umbilical cable, the positive pole of the detector diode on the other end of No. 1 heart yearn of umbilical cable and the ground, a distant place in the interior operator's console of central station of floating dock joins, and the negative pole end of detector diode just has the output of direct impulse voltage; The moving contact of switch knob gets; After pressing switch knob, direct impulse voltage is through the static contact of combined floodgate button, No. 2 heart yearns of umbilical cable; The socket B1 pin of this controller; Current-limiting resistance R4, afterflow capacitor C 1 positive pole, base stage current-limiting resistance R5; The base stage of triode V1 gets direct impulse voltage; And the emitter of triode V1 and collector conducting, the pulse forward current is by base stage → emitter → direct current negative line of triode V1 → got back to transformer KB secondary side a end to form the closed-loop path, and this moment is owing to the emitter of triode V1 and the conducting of collector; The suction line Bao Dedian of solid-state relay J1, the contact J11 adhesive of solid-state relay J1 and contact J12 are closed.Press because the B6 of this controller, the A6 pin two ends and connecing through the switch knob of lead and feeding switch also equal at this moment the switch knob of feeding switch, accomplished long-range combined floodgate task.The positive terminal of afterflow electric capacity also obtains forward current simultaneously when transistor base obtains forward current, and afterflow capacitor C 1 begins charging.When the b of the power transformer KB of this controller second siding ring end during by the forward vanishing and during negative sense; Since the detector diode of ground control cabinet be the former of unidirectional conducting thus this moment detector diode D0 by and can not conducting; 1 charging of afterflow this moment capacitor C finishes, the discharge beginning, and the base stage forward current of triode V1 is supplied with by capacitor C 1; Emitter and the collector of having kept triode V1 continue conducting; The suction line bag of solid-state relay J1 continues that electricity is arranged, and the contact J11 of solid-state relay J1, J12 keep closure, when the b of the secondary side line bag of this control transformer KB end; When getting back to forward once more, 1 pair of transistor base discharge of afterflow capacitor C finishes to recharge beginning.Go round and begin again, after the operator's console operating personnel decontrol switch knob, stop.Inductance energy in the suction coil J10 of the solid-state relay J1 of this controller is by protection diode D3, D4.Short circuit discharges.Played the effect of protection triode V1.
What this controller was taked is duplicate protection, also is GB intrinsic safe explosion-proof [Exib] requirement of explosion proof.So each protected location all is the duplicate protection that adopts in the safeguard measure of this controller.(2/unit of protection diode)
Pulse control is closed a floodgate just the same with the principle of work of separating brake circuit, pulse control reset circuit, all is a kind of transistor switch control circuit, different places be exactly that the task of accomplishing is different.Be separating brake and resetting of task; When the socket output trigger pip A1 of this controller pin; Through No. 1 heart yearn of umbilical cable; After the B2 pin that detector diode, separating brake are often opened button, No. 4 heart yearns of umbilical cable and socket controller joins, as long as press the separating brake task that opening button just can be accomplished the high-low pressure feeding switch down-hole or a distant place.
The socket output signal A1 pin of this controller is through No. 1 heart yearn of umbilical cable; Detector diode resets after the B3 pin of often opening No. 5 heart yearns of button control cable and socket controller joins, as long as press the task that resets that SR just can be accomplished the high-low pressure feeding switch in down-hole or a distant place, ground 300 kilometer range.
Signal feedback indicating circuit principle of work.
A socket A2 pin output direct current+12V voltage of this controller and the end of the auxiliary normally open contact ZN6 in the feeding switch join; The other end of auxiliary normally open contact ZN6 and an end of No. 3 heart yearns of umbilical cable join; The positive terminal of the pilot lamp light emitting diode in the other end of No. 3 heart yearns and the central station of floating dock on the operator's console joins; No. 6 heart yearn one ends of the negative pole end of light emitting diode and umbilical cable join, and the A4 pin of the other end of No. 6 heart yearns and socket controller (12V) joins.When pressing switch knob on the operator's console of operating personnel in central station of floating dock; The auxiliary normally open contact ZN6 of feeding switch combined floodgate feeding switch is closed; Controller A2 pin+the 12V DC current got back to controller A4 pin through No. 3 heart yearns of auxiliary normally open contact umbilical cable of feeding switch, No. 6 heart yearns of pilot lamp light emitting diode, umbilical cable in the operator's console, and direct current 12V negative terminal forms the closed-loop path.The pilot lamp light emitting diode shinny with show feeding switch closure send electricity, light emitting diode do not work explanation feeding switch lock that do not close or tripping operation for some reason.
This essential safe type high-low pressure device feeding switch operated from a distance controller is a connector, and it is installed in the operated from a distance control that just can realize 1-300 kilometers in the flame-proof type high-low pressure feeding switch under the coal mine or in ground each high-low voltage electric power distribution cabinet.
