The invention discloses an electricity testing and grounding function integrated handcart device in the technical field of circuit breaker handcarts. The device comprises a base, a panel and an insulating support, and is characterized in that a handcart in-out operation hole is formed in the middle of the base, a handcart screw rod is correspondingly arranged at the inner side of the handcart in-out operation hole, and a grounding knife switch operation hole is formed in the panel; the inner side of the grounding knife switch operation hole is provided with a grounding knife switch, the insulating support is provided with a conductive plate and an electricity testing contact, and the panel is provided with an electrified display; the inner side detection end of the electrified display is electrically connected with the conductive plate through a contact type sensor, and the electricity testing contact is electrically connected with the conductive plate through a height adjusting mechanism; the inner side of the handcart in-out operation hole is provided with an anti-grounding knife switch electricity testing mechanism, and the inner side of the grounding knife switch operation holeis provided with an anti-electrified grounding knife switch closing mechanism. According to the integrated handcart device, the positions of the electricity testing device and the grounding device are reasonably distributed, it is guaranteed that the integrated handcart device is simple in structure, flexible in operation, economical and practical, and the integrated handcart device conforms to regulations and regulations.
Description
technical field [0001] The invention relates to the technical field of circuit breaker handcart equipment, in particular to a handcart device with integrated electric testing and grounding functions. Background technique [0002] With the continuous development of electric power technology, the current 6-35kV equipment is generally metal armored cabinets. How to directly inspect and ground the busbars and lines of the same voltage level is a long-term problem that has plagued the operation and management units. There are two independent handcarts for the busbar or line inspection and grounding of the switchgear. There are major safety hazards such as lack of perfect electrical and mechanical anti-misoperation locking functions, cumbersome operation and long time. [0003] The switching operation of the busbar from cold standby to inspection and maintenance "Use the electric inspection car to test the electricity at the static contact on the side of the PT knife switch cabine...
