Abstract
The utility model belongs to high-voltage equipment for power transmission and distribution and relates to a plug-in type grounding structure used for a handcart switch cabinet. The plug-in type grounding structure comprises a plug-in type grounding contact that is arranged on the front end surface of a breaker handcart framework and toward the heading direction of a handcart; and a duckbilled type contact matched with the plug-in type grounding contact is arranged on the switch cabinet body and is connected with a grounding system in the cabinet body. By the plug-in type grounding contact arranged on circuit breaker, the plug-in type grounding structure is matched with the duckbilled type contact fixed in the cabinet body to form a plug-in grounding loop; as the plug-in matching is conducted in the heading direction of the handcart, the direction of a plug-in force is in accordance with that of a propelling force of the handcart, thus effectively avoiding the lifting phenomenon of the handcart, guaranteeing the precise matching of a main loop contact and also reducing propelling resistance; and simultaneously, as the duckbilled type movable contact directly supplies contact pressure, the force value does not need adjustment and is stable and reliable.
Description
Technical field
The utility model belongs to the high pressure equipment for power transmission and distribution, relates to a kind of plug-in type ground structure that is used for handcart switch cabinet.
Background technology
In the conventional hand trucks withdraw-type switch cabinet, the ground connection row that circuit breaker cart adopts compression joint type grounding contact and cabinet inner spring to support usually forms grounded circuit, the spring force that supports ground connection row by handcart deadweight and cabinet provides contact pressure, handcart is lifting very easily, cause handcart moving contact and the virtual connection of cabinet fixed contact to be touched, reduced its ampacity, the spring force value that supports ground connection row simultaneously in the cabinet is difficult to regulate, the power value is excessive, the lifting phenomenon is more serious, the power value is too small directly to cause the ground connection failure, has influenced the equipment reliability service.
Summary of the invention
Technical problem to be solved in the utility model is, but a kind of simple in structure, plug-in type ground structure that ground connection property is high that is used for handcart switch cabinet is provided.
Plug-in type ground structure of the present utility model includes one and is installed on the circuit breaker cart frame front end face and towards the plug-in type grounding contact of handcart direction of advance, the duck-beak type contact that matches with the plug-in type grounding contact is installed on the cabinet of switch cubicle, and the grounding system in duck-beak type contact and the cabinet is connected.
The utility model is by being installed in the plug-in type grounding contact and the duck-beak type contacts mates that is fixed in the cabinet on the circuit breaker, form the plug-in type grounded circuit, because the travel direction cooperation of pegging graft before handcart, make mating force consistent with the propulsive force direction of handcart, avoided handcart lifting phenomenon so effectively, guarantee the accurate cooperation of major loop contact terminal, also reduced the resistance that advances; Because the duck-beak type moving contact directly provides contact pressure, the power value need not to regulate and is reliable and stable simultaneously.

Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the plan structure schematic diagram of Fig. 1;
Fig. 3 is the local structure for amplifying schematic diagram of the A of Fig. 2.
Embodiment
As shown in the figure, this plug-in type ground structure includes one and is installed on circuit breaker cart frame 1 front end face and towards the plug-in type grounding contact 2 of handcart direction of advance, the duck-beak type contact 4 that matches with the plug-in type grounding contact is installed on the cabinet 3 of switch cubicle, and the grounding system in duck-beak type contact and the cabinet is connected.Grounding system in the cabinet comprises that the contact that is positioned on the cabinet intermediate membrane and connects each duck-beak type contact connects row 5 and is positioned at the main ground connection row 6 of bottom of cabinet bulk, also includes to be connected contact and to connect the some ground connection branch rows 7 of row between arranging with main ground connection.
