A kind of vacuum circuit breaker on outdoor lamppost, comprises breaker body, breaker body include in set operating mechanism
Cabinet, the two of which side of cabinet is provided with control cable coupling box and aviation plug；The side of breaker body equipped with
The zero sequence current mutual inductor that outlet is connected；Cabinet is also fixedly connected with isolation mount in the side by zero sequence current mutual inductor,
Isolation mount is provided with zero sequential potential transformer away from one end of zero sequence current mutual inductor；The input of zero sequential potential transformer is respectively
Corresponding with upper outlet connect, the output cord Access Control cable coupling box of zero sequential potential transformer, then through aviation plug by controlling
Cable processed connects to intelligent controller；It is provided with bracing frame in the cabinet side relative with zero sequential potential transformer, for installing electricity
Pressure transformer；Voltage transformer is connected by cable with breaker body.
Further, the side of cabinet is provided with manual energy storage handle and the divide-shut brake handss of connection corresponding with operating mechanism
Handle.
Further, described isolation mount also includes for cable guide and spacing fixed structure；Described fixed knot
Structure comprises at least two cylindricality sleeve pipes；The arcwall face of described cylindricality sleeve pipe is fixedly welded on the upper surface of isolation mount, and located at
, to controlling between cable coupling box, the length of single cylindricality sleeve pipe is between 4-8CM for zero sequential potential transformer outfan.
Further, described zero sequence current mutual inductor also includes protective type CT.
This utility model passes through zero sequential potential transformer, the combination of zero sequence current mutual inductor, improves singlephase earth fault
The accuracy judging, can achieve the power supply to intelligent controller by voltage transformer, passes through isolation mount and bracing frame simultaneously
Fixing for the configuration equipment of vacuum circuit breaker integration is connected, the installing space of occupancy reduces, and be easily installed it is not necessary to tediously long
Cable is attached；In addition, cylindricality sleeve pipe can enter walking line to the output cord of zero sequential potential transformer guide and spacing, or will
Sleeve pipe is as the fixing outside tediously long cable of the mounting strong point, thus the operation of more convenient maintainer.
