Abstract

The invention discloses a valve mechanism locking device, which comprises a handcart track, a lower valve mechanism, an upper valve mechanism, a lower valve mechanism locking hole, an upper valve mechanism locking hole and a roller switch, and is characterized in that the lower valve mechanism and the upper valve mechanism are installed at one side of the handcart track, the upper valve mechanism is provided with the upper valve mechanism locking hole, the lower valve mechanism is provided with the lower valve mechanism locking hole, both the upper valve mechanism locking hole and the lower valve mechanism locking hole are internally provided with a latching electromagnet DST, the roller switch is provided with a roller switch auxiliary contact H1, the other end of the roller switch auxiliary contact H1 is electrically connected to a bus and circuit electrification display device H2, and the other end of an auxiliary contact of the bus and circuit electrification display device H2 is connected to the latching electromagnet DST. The valve mechanism locking device can effective prevent occurrence of a human body electric shock accident caused by opening a valve baffle artificially or by mistaken touch through electrical, electromagnetic and mechanical latching functions.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a valve mechanism locking device. Background technique [0002] With the continuous development of electric power technology, 6-35kV equipment is generally replaced by switch cabinets under current circumstances. Personal electric shock accidents caused by accidental opening of the valve baffle during work in the switch room are a major problem that has plagued the operation and management units for a long time. When the switch room of the existing switchgear is working, there is no preventive measure for the opening of the valve baffle, and it is very easy to accidentally touch or artificially open the valve baffle. When working in the switch room of the existing switchgear, there are no preventive measures for the opening of the valve baffle. It is very easy to accidentally touch or artificially open the valve baffle, and personal electric shock accidents occur. Theref...
