A kind of manipulation type temporarily protects circuit, and composition includes: the switch operating handle being connected in power supply circuit, described
Switch operating handle 6,7 nodes and intermediate relay respectively with switch sub-gate circuit connect, the switch operating handle
5,8 nodes with switch closing circuit connect, the switch sub-gate circuit includes trip(ping) circuit and signal circuit, the jump
Lock circuit is in parallel with the signal circuit, and the switch closing circuit includes closing circuit and anti-jump loop, the conjunction
Lock circuit is in parallel with the anti-jump loop.
The manipulation type temporarily protects circuit, and the trip(ping) circuit includes anti-trip relay current start coil, institute
The anti-trip relay current start coil stated is connected with breaker normal open switch, the breaker normal open switch and breaking coil
Series connection, the signal circuit includes signal breaker coil.
The manipulation type temporarily protects circuit, and the closing circuit includes anti-trip relay normally closed switch, described
Anti-trip relay normally closed switch is connected with breaker normally closed switch, and the breaker normally closed switch is connected with closing coil.
The manipulation type temporarily protects circuit, and the anti-jump loop includes anti-trip relay normal open switch, described
Anti-trip relay normal open switch is connected with anti-trip relay voltage recovery coil.
The utility model has the advantages that
1. anti-trip relay is arranged in the utility model, anti-trip relay current start coil is connected in trip(ping) circuit,
Anti-trip relay voltage recovery coil is connected on anti-jump loop, then in parallel with closing circuit, when the non-involution of switch operating handle or
Electric shock is stuck, and closing coil is avoided to be connected again, so that breaker will not close a floodgate again, prevent point/close/point/
Close ... ... chattering.
The utility model setting signal relay, coil are connected after being closed by the node of intermediate relay and are encouraged
Magnetic has the function of that board is fallen in movement, so that operations staff confirms specifically which set protection act after switch trip.
The utility model setting switch operating handle is mainly used for artificial under special circumstances split putting row switching on and off into
Operation guarantees operational safety.
Breaking coil is arranged in the utility model, is encouraged by coil after switch operating handle or intermediate relay node closure electricity
Magnetic makes the iron in it act on brake separating mechanism and carries out switch sub-switching operation by the principle of electric magnetisation, the raw power of magnetic.
Closing coil is arranged in the utility model, by coil magnetization after switch operating handle handle node closure electricity, passes through
The principle of the raw power of electric magnetisation, magnetic makes the iron in it act on switching-on mechanism to carry out switch closing operation.
The utility model structure is simple, safe and reliable, easy to operate, be effectively guaranteed power system security, economy, can
The operation leaned on.
