Description
Technical field
The utility model is a kind of quick outlet module with hardware self-sustaining characteristics, can be used for various power automatic devices.Belong to the technical field that power automatic device is made.
Background technology
In electric power system, various power automation observing and controlling and protective device all need circuit breaker is closed a floodgate and trip operation.Corresponding outlet circuit is all arranged in the device.Because the object of monitoring generally all is the power system device of high voltage, big electric current, so require circuit breaker breaker tripping and closing reliability high.For circuit breaker, the outlet circuit of device is that mechanism is sent in order.If the outlet circuit performance is bad, makes the circuit breaker trip of high-tension apparatus or combined floodgate fail probably, thereby damage power equipment (comprising generator, transformer or the like).Under the serious situation, the stable operation that may influence whole electrical network causes large area blackout.
In a lot of power automatic devices, control to outlet is to adopt the software maintenance or utilize the time-delay characteristics of relay itself to realize basically, all be control under the unknown tripping operation or the situation about whether finishing of closing a floodgate, may have the problem that can not make outside circuit breaker action message in some cases exporting.
Summary of the invention
Technical problem: the purpose of this utility model provides a kind of quick outlet module with hardware self-sustaining effect, and this module can guarantee the quick response of outlet action and the reliable tripping operation or the combined floodgate of external switch.
Technical scheme: in order to realize above purpose, adopt the mode of double relay cascade to realize, at first adopt high-speed relay to realize quick acting, realize the hardware self-sustaining that exports with another current relay.At the control junction closure, external switch action finish and the control coil dead electricity after, the outlet contact is just decontroled automatically, has guaranteed the action message of external switch.
Quick outlet module with hardware self-sustaining effect of the present utility model adopts the double relay cascade system, and the first order adopts the high-speed relay circuit, and the current relay circuit is adopted in the second level; " 4,13 " end of high-speed relay is output, and these two ends are connected on respectively between " 4 " end and switch terminal " 5,8 " of current relay current coil; " 16 " end of high-speed relay is signal input part, and " 8,9 " end of high-speed relay and " 6,7 " end of current relay are signal output part, and the negative pole of diode " D4 " is a signal output part.Be parallel with two groups of diodes and a resistance R 1 in " 1,4 " of current relay current coil, the negative terminal of first group of diode D2 connects current relay current coil " 4 " end, " 1 " end of the positive termination current relay current coil of first group of diode D2; Second group is composed in series by diode D1, D3, and " 4 " end of the positive termination current relay current coil of diode D1, the negative terminal of diode D3 connect " 1 " end of current relay current coil.
Beneficial effect: entire circuit has following characteristics:
A) outlet rapidly.Circuit adopts the double relay cascade system, and first order circuit adopts high-speed relay.Guaranteed muzzle velocity.
B) hardware self-sustaining.Current relay is mainly adopted in the second level of circuit.As long as external switch or circuit breaker do not have tripping or closure, install the oneself's maintenance always of outlet signal, improved the reliability of closing a floodgate and tripping.

Embodiment
Fig. 1 is outlet circuit theory diagrams of the present utility model.This module adopts the double relay cascade system, and the first order adopts high-speed relay RELAY1 circuit, and current relay BJ1 circuit is adopted in the second level; " 4,13 " end of high-speed relay RELAY1 is output, and these two ends are connected on respectively between " 4 " end and switch terminal " 5,8 " of current relay BJ1 current coil; " 16 " end of high-speed relay RELAY1 is signal input part D01, and " 8,9 " end of high-speed relay RELAY1 and " 6,7 " end of current relay BJ1 are signal output part OD01A, and the negative pole of diode " D4 " is signal output part OD01B.
Be parallel with two groups of diodes and a resistance R 1 in " 1,4 " of current relay BJ1 current coil, the negative terminal of first group of diode D2 connects " 4 " end of current relay BJ1 current coil, " 1 " end of the positive termination current relay BJ1 current coil of first group of diode D2; Second group is composed in series by diode D1, D3, and " 4 " end of the positive termination current relay BJ1 current coil of diode D1, the negative terminal of diode D3 connect " 1 " end of current relay BJ1 current coil.
Fig. 2 is the control flow chart of circuit operation of the present invention.At first putting the D01 pin by device software is effective status.This moment RELAY1 the AC coil conducting, and then 9 being connected with No. 13 pins of RELAY1,4 are connected with No. 8 pins.If closing a floodgate to finish or trip, outside circuit breaker do not finish, if promptly have the peripheral operation supply voltage, then BJ1 coil conducting, auxiliary contact BJ1K closure on OD01A and the OD01B.According to the on state characteristic of diode as can be known, the voltage of the 1.5V that has an appointment on 1 and No. 4 pin of BJ1.When delay time then, software D01 pin is set to disarmed state.This moment RELAY1 the AC coil dead electricity, 9 and No. 13 pins of RELAY1 disconnect, 4 and No. 8 pin disconnects.But in this case, the voltage of 1 and of BJ1 No. 4 pin can't disappear.Have only when outside breaker closing finishes or trips to finish, when the operating voltage on OD01A and the OD01B was zero, 1 and No. 4 pin voltage of BJ1 just can disappear.BJ1K tripping this moment.Whole combined floodgate or tripping operation process finish.
