Electricity-test grounding handcart device

Abstract

Based on a series of problems on how to realize direct electricity test and grounding of buses in the same voltage grade, the invention provides an integrated electricity-test grounding device integrating 12 functions of electricity-test grounding handcart integration, electricity-test device integrity check, grounding point uniqueness, prevention of charged interval mis-entering, prevention of charged grounding wire hanging or closing of an earth knife-switch, prevention of switch-on power transmission with the grounding wire or the earth knife-switch, control of valve opening mode, device limit, control of grounding device operating mode, remote signaling, grounding device position check and electrical internal and external connection, and the device is used for 6-35kV metal armoured cabinet bus maintenance grounding.

Description

technical field [0001] The invention belongs to the field of electric machinery, and in particular relates to an electric test grounding handcart device. Background technique [0002] With the continuous development of power technology, 6-35kV equipment is generally replaced by metal armored cabinets under current circumstances. How to directly inspect and ground the busbars of the same voltage level is a major problem that has plagued the operation and management units for a long time. The existing The grounding handcarts for the inspection and inspection of the switchgear busbar are two independent handcarts, which have the integrity detection function of the no-charge display device, the grounding point is not fixed, there is no complete electrical and mechanical and microcomputer five-proof anti-misoperation locking functions, and the operation is cumbersome. Serious violations of regulations and systems such as the "State Grid Corporation Electric Power Safety Work Regu...
