Abstract
An improved 10kv circuit breaker closing loop is composed of a circuit breaker normally closed auxiliary contact (DL), a circuit breaker closing coil (HC), a hand-operated closing switch (KK), a remote control closing switch (YH), a control circuit positive power supply and a control circuit negative power supply. A mode for improvement is that an energy storage completion normally closed contact (CK) of a circuit breaker energy storage travel switch is in series connection in a circuit breaker normally closed auxiliary contact (DK) loop so as to avoid burnout of the circuit breaker closing coil; improvement measures are simple and are easy to realize; and the cost is low.
Description
Technical field
The utility model relates to the control loop of power high voltage circuit breaker.
Background technology
10KV vacuum circuit-breaker is because control loop design is unreasonable, often occur spring not energy storage put in place in situation and close a floodgate, cause breaker closing coil burnout.
Utility model content
The purpose of this utility model is to overcome the problems referred to above, and a kind of improved 10kV closing circuit of circuit breaker of avoiding Burnout of Closing Coil is provided.
For achieving the above object, the technical solution adopted in the utility model is: improved 10kV closing circuit of circuit breaker, formed by the normally closed auxiliary contact of circuit breaker (DL), breaker closing coil (HC), closing by hand switch (KK), remote control closing switch (YH), the positive and negative power supply of control loop, it is characterized in that: the energy storage of the breaker energy storage travel switch of connecting in the normally closed auxiliary contact of circuit breaker (DL) loop completes normally closed contact (CK).
The utility model compared with prior art has the following advantages:
1, avoid breaker closing coil burnout.
2, corrective measure is simple, and cost is low.
Brief description of the drawings
Accompanying drawing 1 is the closing circuit of circuit breaker before improving.
Accompanying drawing 2 is the closing circuit of circuit breaker after improving.
Icon explanation:
DL. the normally closed auxiliary contact of circuit breaker; HC. breaker closing coil; KK. closing by hand switch; YH. remote control closing switch; + ,-. the positive and negative power supply of control loop; CK. the energy storage of travel switch completes normally closed contact.
Embodiment
Accompanying drawing 1 is for improving Qian road device closing circuit, accompanying drawing 2 is for improving Hou road device closing circuit, 10kV closing circuit of circuit breaker before improvement, by the normally closed auxiliary contact of circuit breaker (DL), breaker closing coil (HC), closing by hand switch (KK), remote control closing switch (YH), control loop just, negative supply composition, improved procedure is: the energy storage of the breaker energy storage travel switch of connecting in the normally closed auxiliary contact of circuit breaker (DL) loop completes normally closed contact (CK), this has just solved the problem of Burnout of Closing Coil, specific embodiment is LX12-4380V3A two to be driven to two travel switches that close change LX12-6380V10A tri-into and drive three travel switches that close, another of travel switch is connected to remote signalling loop to normally closed contact, remind operator as remote monitoring signal, prevent misoperation.
