Fig. 1 is schematic diagram of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, the invention will be further described, and embodiments of the present invention include but not limited to the following example.
As shown in Figure 1, the electric anti-jump loop of a kind of circuit breaker tandem, bag tripping operation control loop, shutting-brake control loop and anti-jump control loop, formed primarily of tripping operation latching relay TBJ, combined floodgate latching relay HBJ, anti-trip relay FTJ, auxiliary contacts of circuit breaker DL, breaking coil TQ, closing coil HQ, trip switch TZK, closing switch HZK.Tripping operation control loop one end of the electric anti-jump loop of described circuit breaker tandem is connected with negative pole control bus (-KM), and the other end often opens auxiliary contact DL1 successively with breaking coil TQ, circuit breaker, the latching relay TBJ that trips, trip switch TZK are connected with positive pole control bus (+KM) after being in series with first parallel circuits often opening auxiliary contact TBJ1 of the latching relay TBJ that trips; One end, shutting-brake control loop of the electric anti-jump loop of described circuit breaker tandem is connected with negative pole control bus, and the other end is connected with positive pole control bus after being in series with first parallel circuits often opening auxiliary contact HBJ1 of combined floodgate latching relay HBJ with the normally closed auxiliary contact FTJ2 of closing coil HQ, circuit breaker normally closed auxiliary contact DL2, anti-trip relay FTJ, combined floodgate latching relay HBJ, closing switch HZK successively; Anti-jump control loop one end of the electric anti-jump loop of described circuit breaker tandem is connected with negative pole control bus, the other end successively with anti-trip relay FTJ often open that auxiliary contact FTJ1 and second of the latching relay TBJ that trips often leave the parallel circuits of auxiliary contact TBJ2, anti-trip relay FTJ, closing switch HZK are connected with positive pole control bus after being in series with first parallel circuits often opening auxiliary contact HBJ1 of combined floodgate latching relay HBJ.
The operation principle of this anti-jump loop is: when circuit breaker carries out closing operation or closing pulse signal is effective, closing switch HZK closes, combined floodgate latching relay HBJ coil obtains electric, first of combined floodgate latching relay HBJ often opens auxiliary contact HBJ1 and closes, closing coil HQ obtains electric, complete breaker closing action, it is closed that then circuit breaker normally closed auxiliary contact DL2 disconnects, circuit breaker often opens auxiliary contact DL1, cuts off shutting-brake control loop, when circuit breaker carries out trip operation or tripping operation pulse signal is effective, trip switch TZK closes, tripping operation latching relay TBJ coil obtains electric, first of tripping operation latching relay TBJ often opens auxiliary contact TBJ1 and closes, breaking coil TQ obtains electric (circuit breaker is often opened auxiliary contact DL1 and closed), complete circuit breaker trip action, then circuit breaker often opens auxiliary contact DL1 disconnection, circuit breaker normally closed auxiliary contact DL2 is closed, cuts off tripping operation control loop, when breaker closing pulse signal is effectively and after completing breaker switching-on operation, if closing contact is off, and now line failure, protective device starting protection function, the control loop that will trip is connected, make circuit breaker trip, second of the latching relay TBJ that now trips often opens auxiliary contact TBJ2 and connects, anti-trip relay FTJ coil is made to obtain electric, the normally opened contact FTJ1 of anti-trip relay FTJ closes, anti-jump control loop is made to continue electric, the normally closed auxiliary contact FTJ2 of anti-trip relay FTJ disconnects simultaneously, long-term cut-out shutting-brake control loop, circuit breaker can not be closed a floodgate again, thus the circuit breaker breaker tripping and closing repeatedly when preventing line fault not get rid of, reach the anti-bouncing function of circuit breaker relaying protection.
Specific in an application examples, tripping operation latching relay TBJ uses Panasonic relay ST2-DC1.5V, combined floodgate latching relay HBJ uses Panasonic relay ST2-DC1.5V, anti-trip relay FTJ uses Panasonic relay ST1-DC48V, can form the electric anti-jump loop of the circuit breaker being applicable to 10kV and following electric pressure.The electric anti-jump loop of described circuit breaker tandem uses the anti-bouncing function often opening auxiliary contact FTJ1 and normally closed auxiliary contact FTJ2 realizing circuit of anti-trip relay FTJ, use the current start coil of anti-trip relay to realize anti-bouncing function with voltage hold-in winding with conventional tandem anti-jump loop to compare, there is the advantages such as circuit structure is simple, stable performance, use and maintenance convenience.
More than that better enforcement of the present invention is illustrated, but the invention is not limited to described embodiment, those of ordinary skill in the art are under the prerequisite without prejudice to invention spirit, for solving same technical problem, even if the equivalent variations of carrying out on basis of the present invention or replacement, the essence of its technical scheme is still the same with the present invention, and these equivalent variations or replacement are all included in the application's claim limited range.
