Abstract
A rapid electricity testing grounding telescoping dolly of a high voltage switch cabinet comprises a frame, a chassis vehicle, a moving contact and a contact arm. A top of the frame is provided with an electricity testing apparatus. The frame is provided with a grounding switch. The grounding switch is connected with a grounding switch operation handle. By using the technical scheme, the high voltage electricity testing apparatus is added so that an electricity testing function is possessed. The grounding switch is used to close a short circuit current so that the bus is grounded. When a sensor and a high voltage display have faults, the grounding switch is closed and operation personnel is not hurt so that safety and reliability of a grounding dolly are increased.
Description
Technical field
The utility model belongs to electric power system, relates to transformer station's high-tension switch cabinet field, specifically a kind of maintenance of high-voltage switch cabinet flexible dolly of electrical verification ground connection.
Background technology
A. trolley type high voltage switch cabinet needs periodic inspection, and the maintainer enters in charged interval, has potential safety hazard, for the sake of security, usually need to first with a grounding trolley, push service position, with the three-phase bus short circuit and with the earth, be connected, the maintainer just can enter.Must then just can push grounding trolley with the first electrical verification of electricity check trolley before existing grounding trolley pushes, need twice dolly carrying, complicated operation, very inconvenient, and also existing grounding trolley is irrelevant closes ability, and its security reliability is poor.
B. there is no the transformer station of dolly, after the operations staff does not have voltage to show according to electrification display, then opening the rear side shut, with the electrical verification rod, the bus of exposed part is being carried out electrical verification, after electrical verification is errorless, could be in cabinet hanging earthing conductor.In this process, when rack is more, easily go to the wrong way rack room every, have serious potential safety hazard.
The utility model content
The purpose of this utility model is exactly to overcome the defect that exists in above-mentioned prior art, and providing a kind of can disposablely push, and electrical verification and ground connection can be completed simultaneously, increases simultaneously the grounding trolley of grounding trolley making current ability function, increases fail safe.
The structure of this dolly mainly comprises: chassis vehicle, vehicle frame, operating grip, earthed switch, electrification display, transducer, short circuit copper bar, contact arm, moving contact.
It is vehicle frame on chassis vehicle.Vehicle frame is provided with operating grip, and earthed switch, and the vehicle frame top is provided with electrification display, is provided with transducer in vehicle frame, and transducer one end connecting portion below is connected with and slightly connects copper bar.
Adopt the beneficial effect of the technical program: increased the high voltage testing device, earthed switch has the ability of folding short circuit current with busbar grounding, when transducer and high voltage display break down (during the electrical verification mistake), the earthed switch that closes can not injure operating personnel yet, improved the security reliability of grounding trolley, electrical verification ground connection can be completed simultaneously.
Description of drawings
Fig. 1 is the structure chart of the quick electrical verification of high-tension switch cabinet, the flexible dolly of ground connection;
In figure: 1-chassis vehicle, 2-vehicle frame, 3-operating grip, 4-earthed switch, 5-electrification display, 6-transducer, 7-short circuit copper bar, 8-contact arm, 9-moving contact.
Embodiment
Now contrast Figure of description and repeat the flexible dolly of the quick electrical verification ground connection of the utility model high-tension switch cabinet again, its structure comprises: chassis vehicle 1, vehicle frame 2, operating grip 3, earthed switch 4, electrification display 5, transducer 6, short circuit copper bar 7, contact arm 8, moving contact 9; It is vehicle frame 2 on chassis vehicle 1, vehicle frame 2 tops are provided with electroscopic device, also be provided with earthed switch 4 on vehicle frame 2, be connected with earthed switch operating grip 3 on earthed switch 4, electroscopic device is by establishing transducer 6 in vehicle frame, transducer one end is connected with contact arm 8, the end of contact arm 8 is provided with moving contact 9, contact arm 8 is connected bottom with transducer 6 and is connected with short circuit copper bar 7, vehicle frame 2 tops are provided with electrification display 5, can realize quick electrical verification, utilize earthed switch 4 to close and close short circuit current by busbar grounding, improve the security reliability of grounding trolley.
