Below operation principle of the present invention is elaborated.
As depicted in figs. 1 and 2, a kind of original 10kV handcart type high voltage switch cabinet control loop, its switch (also claiming circuit breaker) is in the time of gate-dividing state, all normal opened contacts disconnect, normally closed contact closure, now in the diode of sub-gate signal lamp, thereby current flowing is luminous, but this electric current is very little, though flow through closing coil HQ, not enough so that its action.When sending reclosing command; after the closing contact 5-6 conducting of remote control closing switch S-2 or change over switch SA; protective relaying device sends closing pulse signal by contact P:318; because normally closed contact TBJ-1 and the breaker trip switch DL-2 of anti-trip relay TBJ are all closed; therefore closing coil HQ is charged, breaker closing.After closing a floodgate successfully, breaker trip switch DL-2 disconnects, breaker trip switch DL-1 closure, and separating brake indicator light extinguishes, and combined floodgate indicator light is lighted.
If now change over switch SA fault or human operational error, makes the closing contact 5-6 of change over switch SA always in "on" position, or remote control closing switch S-2, P:318 combined floodgate contact fail to return in time, and P:318 will continue conducting positive supply.Suppose to close a floodgate in permanent fault, relaying protection, by automatic trip, because closing circuit continues conducting positive supply, has electric current to flow through closing coil HQ all the time, and switch will close a floodgate again in permanent fault so, may cause extensive damage to the person, equipment.Add anti-jump loop, 6-9-10 branch road in Fig. 1, just can avoid the generation of this situation.Make after switch combined floodgate when HQ is charged, breaker trip switch DL-3 closure, anti-trip relay TBJ is charged, and the normally closed contact TBJ-1 of anti-trip relay TBJ is disconnected, and closing circuit is conducting no longer.Meanwhile, the normal opened contact TBJ-2 closure of anti-trip relay TBJ, forms self-holding circuit, until no longer conducting positive supply of P:318.
Anti-jump loop plays a very good protection to circuit breaker, has brought trouble but to relaying protection sub-gate signal lamp.After switch closes a floodgate, anti-jump loop 6-9-10 branch road continues conducting, makes sub-gate signal lamp utilize this loop Continuous-flow overcurrent, the trouble waters that after so just having caused switch to close a floodgate, divide, switching signal lamp are all lit.In on-the-spot application, normal employing changed not with anti-jump handcart-type switch or changes the generation of not avoiding this situation with the protective device of separating brake monitoring circuit.
For addressing the above problem, as shown in Figure 3, the positive-negative power port 311 of protective relaying device P and 319 is connected respectively the both positive and negative polarity (+KM ,-KM) of controlling power supply, the separating brake arrival end 312 of protective relaying device is connected and is controlled positive source by change over switch SA separating brake contact 7-8, change over switch SA separating brake contact 7-8 remote control separating brake in parallel switch S-1; The combined floodgate arrival end 316 of protective relaying device P is connected and is controlled positive source by change over switch SA closing contact 5-6, change over switch SA closing contact 5-6 remote control closing switch in parallel S-2; Between the contact 301 and 313 of protective relaying device P, be connected to trip pressing plate 1XB, the combined floodgate of protective relaying device P monitors that outlet 314 connecting breaker travel switch DL-1 control power cathode with being connected after breaking coil, separating brake is connected with three tunnels after monitoring the normally closed contact that exports 317 connection relay protection signal lamps switching intermediate relay ZJ, and normally-closed contact TBJ-1, breaker trip switch DL-2 that a road connects anti-trip relay successively control power cathode with being connected after closing coil HQ; Access control power cathode after one road connecting breaker travel switch DL-3, anti-trip relay coil TBJ, the two ends of breaker trip switch DL-3 are parallel with the normally opened contact of an anti-trip relay TBJ; Access control power cathode after one road connecting breaker travel switch DL-4, the normally opened contact TBJ-3 of anti-trip relay TBJ and the coil of intermediate relay ZJ.
The present invention is 6-11-12-10 branch road in parallel on former anti-jump loop; increase a relay protection signal lamp and switched intermediate relay ZJ, breaker trip switch DL-4 and anti-trip relay normally opened contact TBJ-3, and the normally closed contact ZJ of the auxiliary relay of having connected between P:317 and contact 6.
After switch closes a floodgate, breaker trip switch DL-4 closure, the charged normally opened contact TBJ-3 that makes of coil of anti-trip relay TBJ is also closed, intermediate relay ZJ is charged by the loop conducting of " P:318-6-11-12-10 ", the normally closed contact ZJ of auxiliary relay is disconnected, and separating brake indicator light has just extinguished.
If block or human operational error generation control switch contact, automatics contact, instruction sustainable existence causes closing a floodgate, the anti-trip relay TBJ coil always charged normally opened contact TBJ-3 that makes remains closed, intermediate relay ZJ coil continues the charged normally closed contact ZJ that makes and remains open, and separating brake indicator light will keep the state correctly extinguishing like this.
If trip protection or operation tripping operation, breaker trip switch DL-4 will disconnect, and intermediate relay ZJ coil losing electricity makes normally closed contact ZJ closure, and sub-gate signal lamp is correctly lighted by " P:317-6-7-8-10 " loop conducting.
The above is the preferred embodiment of the present invention, for those skilled in the art, under the premise without departing from the principles of the invention, can also make some improvements and modifications, and these improvements and modifications are also regarded as protection scope of the present invention.
