Position relay HHJ1 needs series connection divider resistance R to carry out adhesive, and closing coil HQ and breaking coil TQ is having series connection partial pressure electricity
Adhesive is unable to during resistance 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, it is ensured 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, it is only 10 Europe or so, operation voltage to make its coil outer resistance
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 ensure that hand is jumped relay STJ1 and breaking coil TQ and acted simultaneously.
9 sets of electrical equipments, 9 sets of respective analog breaker circuit structures of formation of apparatus of the present invention, its structure and work are former
All same is managed, 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 jump position relay TWJ1 coil adhesives, and
And the jump position indicator lamp LED1 on resistance R1 is lighted, and represents system 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 outside hand 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 not with power on, close position indicator lamp LED2 and do not work, it is 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, and represents system 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, acts hand jump relay STJ1 contacts and breaking coil 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 not with power on, jump position indicator lamp LED1 and do not work, it is 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 is expressed as position state after closing, 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 lower premised on technical solution of the present invention, gives detailed embodiment and tool
The operating process of body, but protection scope of the present invention is not limited to the above embodiments.Method therefor is such as without spy in above-described embodiment
It is conventional method not mentionlet alone bright.
