Damage at protection supervisory equipment or communication device; circuit breaker is made to lose remote operation function; but when circuit breaker self control loop is intact, according to the principle of electric automatic operation, the utility model realizes controlling the automatic trip of circuit breaker by its external electric loop.
The utility model solves after circuit breaker loses behaviour far away or local operation function, realizes excising load fast to the electric automatic operation of circuit breaker, realizes circuit breaker on-load operation problem on the spot.
Application scenario of the present utility model is two second part at transformer.
As shown in Figure 1, the utility model comprises power supply, circuit breaker, time delay return relay, time delay exit relay, the fast switch-dividing of DC bipolar and some binding posts.Time delay return relay is connected with power supply via two binding posts by the fast switch-dividing of DC bipolar again, and these two binding posts are power input; The normally closed switch of time delay return relay is connected with the coil of time delay exit relay, and the normal open switch of time delay exit relay is also connected with circuit breaker by two binding posts, and these two binding posts are time delay output.
The utility model also comprises signal lamp, and the series circuit that signal lamp and the normal open switch of time delay return relay form is connected between the two ends be not connected with power supply of the fast switch-dividing of DC bipolar.
As shown in Figure 2, the utility model comprises time delay return relay SJ1, time delay exit relay SJ2, signal lamp XD, the fast switch-dividing DK of DC bipolar, binding post JXZ1, binding post JXZ2, binding post JXZ3, binding post JXZ4, protective resistance R, circuit breaker and power supply.
The utility model comprises time delay involution start-up circuit, time delay outlet start-up circuit, device working indicating and time delay outlet trip circuit.Time delay involution start-up circuit is composed in series by the coil of time delay return relay SJ1 and protective resistance R.Time delay outlet start-up circuit is composed in series by the coil of time delay exit relay SJ2 and the normally closed switch of time delay return relay SJ1.Device working indicating is composed in series by the normal open switch of signal lamp XD and time delay return relay SJ1.Time delay outlet trip circuit is composed in series via binding post JXZ3 and circuit breaker by the normally closed switch of time delay exit relay SJ2.
Binding post JXZ1 is connected between No. 1 switch of power positive end and the fast switch-dividing DK of DC bipolar, and binding post JXZ2 is connected between No. 2 switches of power supply negative terminal-KM and the fast switch-dividing DK of DC bipolar.No. 2 switches of the fast switch-dividing DK of DC bipolar are connected between binding post JXZ2 and binding post JXZ4.Time delay involution start-up circuit, time delay are connected to after exporting start-up circuit, device working indicating three parallel connection between No. 1 switch of binding post JXZ4 and the fast switch-dividing DK of DC bipolar.Time delay outlet trip circuit is connected between binding post JXZ4 and power supply negative terminal-KM.
In Power Selection, the utility model adopts DC control supply in breaker cabinet, in order to avoid introduce interference, it is wired that coincidence circuit connects use, avoids radio to interference of the present utility model.The utility model only need access two direct current supply lines and (conjunction) brake cable is jumped in an outlet, can realize the electric emergency operation to circuit breaker.
Time delay return relay and time delay exit relay all can adopt the time relay.The utility model freely can arrange outlet operate time (as shown in time delay exit relay SJ2 in Fig. 2), can be set according to distance the suitable time, convenient operation personnel evacuate to safety zone, this device is also provided with the adjustable auto-returned time (as shown in time delay return relay SJ1 in Fig. 2) simultaneously, in order to avoid circuit breaker can not burn out circuit breaker jumping (conjunction) brake cable coil element during correct operation.The delay time of these two relays all can carry out arranging and adjust, but needs the delay adjustments value guaranteeing time delay return relay to be greater than the delay adjustments value of time delay exit relay, in order to avoid device failure.
Indicator light in electric operation loop of the present utility model, not only can the input of Monitor and Control power supply whether normal, also can judgment means element manipulation whether normal.
Use of the present utility model can excise the faulty equipment that protection supervisory equipment damage or circuit breaker trip coil or control loop damage in shorter time, has good actual application value.
(1) safety benefit.Application of the present utility model reduces about 70% before circuit breaker unprotect running time and failure operation time are comparatively used, and makes electrical network, the security reliability of equipment obtains effective raising.
The use of this emergency treatment device when breaker open operation fault simultaneously avoids the execute-in-place of personnel, effectively protects the safety of operation and repair and maintenance personnel, plays a good role to raising fortune inspection safety in production level.
