Abstract
The utility model discloses a grounding handcart of a centrally-mounted switch cabinet, which comprises a chassis, wherein a handcart skeleton is installed on the chassis, the inner side surface of the handcart skeleton is provided with a grounding copper bar, one end of the grounding copper bar is fixed on the handcart skeleton, the grounding copper bar is provided with a touch arm, and the outer end part of the touch arm is provided with a contact terminal. When a bus-bar of a bus-bar chamber or a cable chamber is required to be grounded during the repairing of equipment, the grounding handcart is pushed into the switch cabinet, the contact terminal of the grounding handcart is communicated with a stationary contact terminal of the switch cabinet, and then an earth wire is hung on the grounding copper bar to realize the grounding function, so the bus bar can be grounded without opening the bus-bar chamber from the top of the switch cabinet, and the grounding handcart is simple and convenient to operate. The grounding copper bar, the touch arm and the contact terminal are uniformly arranged at one side of the handcart skeleton, so the components are convenient to repair and replace, and the exchangeability is strong; and the overall size of the handcart is identical to that of a circuit breaker, so the handcart is completely matched with the circuit breaker, and the exchangeability is strong.
Description
Technical field
The utility model relates to a kind of corollary equipment of 10 kilovolts of high-tension switch cabinets---and the ground connection handcart in the mid-handcart cabinet of withdraw-type in circuit or overhaul of the equipments, is advanced to the ground connection handcart in the switch cubicle and realizes that bus or circuit play ground protection and use.
Background technology
At present, 10 kilovolts of high-tension switch cabinets are anti-complete owing to five, bus-bar room, cable vault's sealing, circuit or equipment are when maintenance, there is not the place can hang temporary ground wire, because of before bus does not hang up earth connection, open bus-bar room and the cable vault all violates safe operation rules, so will be before opening bus-bar room and cable vault, elder generation's hanging earthing conductor on bus, must use the ground connection handcart, the ground connection handcart is divided into bus-type ground connection handcart and circuit formula ground connection handcart, also calls ground connection handcart or following ground connection handcart.Can't go to be connected with temporary ground wire on the fixed contact in bus bar side and line side, be with temporary ground wire to busbar grounding, need open bus-bar room from the cabinet top, that has only that the domestic factory of only a few produces beats bonnet, the trouble that operates, inconvenience.
Summary of the invention
