Description
Technical field
The utility model relates to a kind of substation equipment, is specifically related to a kind of switch cabinet electrified display positive locking mechanism.
Background technology
The XGN switch cubicle that 10kV electrical network generally uses, i.e. box fixed indoor ac metal closing switch gear, its line side is charged, without electrification display and mechanical latching forcing device.The charged uncertainty in line side, when circuit and switch cabinet equipment maintenance accident treatment, line side electrical ground disconnecting link still can close, operation and maintenance process in, potential safety hazard is existed to the person and equipment, the transformation of XGN switch cabinet electrified display positive locking must be carried out, eliminate accident potential technically.
Summary of the invention
The purpose of this utility model is to provide a kind of XGN of display switch cubicle line side electriferous state and the switch cabinet electrified display positive locking mechanism that locking grounding switch makes it close a floodgate when overhaul of the equipments.
In order to reach above object, the technical scheme that the utility model adopts is as follows:
Switch cabinet electrified display positive locking mechanism described in the utility model comprises cabinet, be arranged on the guidance panel before cabinet, be arranged on the isolating switch in cabinet and circuit breaker, guidance panel is provided with grounding switch operating handle, in line side, voltage sensor is installed, the output shunt voltage display of described voltage sensor and electromagnetic lock, described voltage display and electromagnetic lock are fixedly mounted on guidance panel, be positioned at the side of grounding switch operating handle, described electromagnetic lock comprises housing, be fixedly mounted on the solenoid in housing, be inserted into the driving shaft in solenoid inner core, the two ends of described driving shaft are installed with moving armature and spring base respectively, return spring is provided with between described spring base and the inwall of housing, front end and the lockhole be arranged on grounding switch operating handle sidewall of described driving shaft match.
Described voltage sensor is voltage transformer.
After adopting technique scheme, this positive locking mechanism realizes the charged information prompting in line side, and achieves ground, electromagnetic lock blocked line side cutter function simultaneously, thoroughly eliminates safe hidden trouble, ensures person isolation, eliminate accident factor technically.
