When current value is more than the setting valve of protective device LJ, current relay coil excitation node is closed, turn-on time relay circuit,
Time relay coil excitation is closed conducting intermediate relay by certain time-delay posterior nodal point, passes through the node of intermediate relay
Realize the tripping of protective device and Continuity signal relay；
When closing operation, switching manipulation handle is turned to closing position, 5,8 nodes are closed, and breaker normal open switch is closed, anti-jump
Relay current actuating coil has electric current to pass through, and anti-trip relay normal open switch is closed therewith, and anti-trip relay voltage restores line
Self-sustaining is enclosed, anti-trip relay normally closed switch disconnects closing circuit, when the non-involution of breaker or contact are stuck, avoids closing line
Circle is connected again so that breaker will not close a floodgate again.
Advantageous effect：
1. present invention setting anti-trip relay, anti-trip relay current start coil is connected in trip(ping) circuit, anti-jump relay
Device voltage recovery coil is connected on anti-jump loop, then in parallel with closing circuit, when the non-involution of switching manipulation handle or gets an electric shock by card
Firmly, closing coil is avoided to be connected again so that breaker will not close a floodgate again, prevent point/close/point/it is existing to close ... ... jump
As.
Setting signal relay of the present invention, conducting progress excitation, tool after coil is closed by the node of intermediate relay
There is action to fall board function, so that operations staff confirms specifically which set protection act after switch trip.
Switching manipulation handle is arranged in the present invention, is mainly used for artificial split row switching on and off of putting under special circumstances and operates,
Ensure operational safety.
Breaking coil is arranged in the present invention, and coil magnetization after electricity is closed by switching manipulation handle or intermediate relay node,
So that the iron in it is acted on brake separating mechanism by the principle of electric magnetisation, magnetic life power and carries out switch sub-switching operation.
Closing coil is arranged in the present invention, and by switching manipulation coil magnetization after teach-by-doing node closure electricity, it is raw to pass through electricity
Magnetic, magnetic life power principle make the iron in it act on switching-on mechanism to carry out switch closing operation.
It is the configuration of the present invention is simple, safe and reliable, easy to operate, it is effectively guaranteed power system security, economy, reliable
Operation.
