Relay in the utility model in electrical equipment is broadly divided into two kinds, described jump position relay TWJ1, closes position Position relay HHJ1 is the 110V relays with voltage class, described closing coil HQ and tripping operation line after relay HWJ1, conjunction Enclose TQ be with voltage class 220V relays, two kinds of voltage class differences, jump position relay TWJ1, close position relay HWJ1, Position relay HHJ1 needs divider resistance R progress adhesives of connecting after conjunction, and closing coil HQ and breaking coil TQ is having series connection point Adhesive is unable to during piezoresistance R.
Matched during described divider resistance R resistance design with the resistance of above two coil, make the electricity after partial pressure Pressure grade is consistent with the voltage class of above two relay, ensures that above two relay presses design action.
In addition, it is producer's a small resistor customized, low-voltage type DC relay that described hand, which jumps relay STJ1, determine When doing on its coil 10 Europe in parallel or so small resistor, make its coil outer resistance be only 10 Europe or so, operation voltage For direct current 5V, when it is in parallel with divider resistance R2, resistance R2 can be considered as close to short-circuit condition, when it and resistance are 300 Europe During the breaking coil TQ series connection of nurse or so, it can ensure that hand is jumped relay STJ1 and breaking coil TQ while acted.
9 sets of electrical equipments of the utility model device form 9 sets of respective analog breaker circuit structures, its structure and work Make principle all same, by taking transformer 1B high pressure side loops as an example, operation principle is as follows:
1st, it is mimic-disconnecting switch separating brake shape when the high breaker open operations of the breaker 1B on mimic-disconnecting switch casing top panel State:
1.1 when the high breaker open operations of the breaker 1B on mimic-disconnecting switch casing top panel, and its normally-closed contact DL-1 is Closure state, now, described jump position relay and closing circuit and power on, position relay TWJ1 coil adhesives are jumped, and And the jump position indicator lamp LED1 on resistance R1 is lighted, system is represented to jump position state;
And now, because the resistance R1 in described jump position relay and closing circuit serves partial pressure effect, make combined floodgate Coil HQ does not reach pick-up voltage, it is impossible to adhesive;
At this moment, signal can be closed by the hand of outside and carries out hand conjunction action, after hand conjunction action, jump position relay TWJ1 and resistance R1 closes loop short circuit by hand, jumps position relay TWJ1 and disconnects, and jumps position indicator lamp LED1 and extinguishes;Now, closing coil HQ adhesives, mould Plan release unit is hand conjunction state, position relay HHJ1 closing coil adhesive after conjunction.
1.2 when the high breaker open operations of the breaker 1B on mimic-disconnecting switch casing top panel, and its normally opened contact DL-2 is Open-circuit condition, now, described conjunction position relay and trip(ping) circuit close position indicator lamp LED2 and not worked not with power on, outside It is invalid operation that hand, which jumps signal, and outside hand jumps exercise void.
2nd, it is mimic-disconnecting switch separating brake shape when the high breaker closings of the breaker 1B on mimic-disconnecting switch casing top panel State:
2.1 when the high breaker closings of the breaker 1B on mimic-disconnecting switch casing top panel, and its normally opened contact DL-2 is Closure state, now, described conjunction position relay and trip(ping) circuit and power on, and position relay HWJ1 coil adhesives, and And the jump position indicator lamp LED2 on resistance R2 is lighted, system is represented to close position state;
And now, because the resistance R2 in described conjunction position relay and trip(ping) circuit serves partial pressure effect, make tripping operation Coil TQ does not reach pick-up voltage, it is impossible to adhesive;
At this moment, the hand that can receive outside jumps signal progress hand bounce work, after hand bounce is made, conjunction position relay HWJ1 and electricity Resistance R2 is connect by hand rebound is short out, is closed position relay HWJ1 and is disconnected, and is closed position indicator lamp LED2 and is extinguished;Now, breaking coil TQ and hand Relay STJ1 adhesives are jumped, mimic-disconnecting switch device is that hand jumps state, position relay HHJ1 switching winding adhesive after conjunction.
This coil connecting structure that hand jumps relay STJ1 makes breaking coil could to be acted by STJ1 coil, prevents Only breaking coil TQ skips hand and jumps relay STJ1 actions, makes hand jump relay STJ1 contacts and breaking coil action inconsistent.
2.2 when the high breaker closings of the breaker 1B on mimic-disconnecting switch casing top panel, and its normally-closed contact DL-1 is Open-circuit condition, now, described jump position relay and closing circuit are jumped position indicator lamp LED1 and not worked not with power on, outside It is invalid operation that hand, which closes signal, and outside hand closes exercise void.
Relay HHJ1 principles in position are after conjunction:
When hand, which closes signal, to be connected, relay closing coil adhesive in position after conjunction, position state after closing is expressed as, now, no matter Breaker DL is combined floodgate or gate-dividing state, and HHJ1 is position state after closing, when only hand jumps signal connection, position relay after conjunction During switching winding adhesive, just it is changed into gate-dividing state.
Above example is implemented under premised on technical solutions of the utility model, gives detailed embodiment With specific operating process, but the scope of protection of the utility model is not limited to the above embodiments.Side used in above-described embodiment Method is conventional method unless otherwise instructed.
