Embodiment Construction

[0013] Gas-insulated metal-enclosed switchgear is a high-voltage power system transmission and distribution equipment for receiving and distributing electric energy. Widely used in power transmission and distribution systems such as substations, power plants, factories and mines. Such as figure 1 As shown, a gas-insulated metal-enclosed switchgear includes a primary wiring device. The wiring device is mainly composed of a circuit breaker 1, a circuit breaker inlet and outlet terminal 2, a bus coupler 3 for the cabinet, and a bus room inlet and outlet terminal 4. Composed of 5 busbar rooms.

[0014] The circuit breaker 1 is an external structure, which is provided with a circuit breaker inlet and outlet terminal 2; the bus room 5 is provided with a bus room inlet and outlet terminal 4, and the circuit breaker inlet and outlet terminals 2 and the bus room inlet and outlet terminals 4 pass through the bus coupler for the cabinet 3 Connection conducts and carries current. The e...

Abstract

The invention relates to a gas-insulated metal-closed switch cabinet, comprising a primary wiring device, wherein the wiring device is mainly composed of a circuit breaker, a line incoming and outgoing end of the circuit breaker, a bus coupling device for a combined cabinet, a line incoming and outgoing end of a bus chamber, and the bus chamber; the circuit breaker is in an external structure and is provided with the line incoming and outgoing end of the circuit breaker; the bus chamber is provided with the line incoming and outgoing end of the bus chamber; the line incoming and outgoing end of the circuit breaker is connected and conducted with the line incoming and outgoing end of the bus chamber through the bus coupling device for the combined cabinet so as to carry current; the circuit breaker is fixedly connected with the bus chamber through a bolt; and an insulating silica gel layer is pressed on the bus coupling device for the combined cabinet at the same time. The gas-insulated metal-closed switch cabinet disclosed by the invention not only has the advantages of convenience in maintainance, repair and replacement of circuit breaker elements in metal-closed air-insulated switch equipment, but also has the characteristics of miniaturization, intellectualization, free maintenance, full working conditions and the like.

Description

technical field [0001] The invention belongs to the field of electromechanical manufacturing, in particular to a gas-insulated metal-enclosed switchgear. [0002] Background technique [0003] Among the existing 3kV ~ 40.5kV and above power transmission and distribution equipment, the transmission and distribution high-voltage switchgear has two structural forms: metal-enclosed air-insulated switchgear and cabinet-type gas-insulated metal-enclosed switchgear (C-GIS). [0004] Metal-enclosed air-insulated switchgear includes metal-enclosed armored switchgear, metal-enclosed compartment switchgear, metal-enclosed box-type switchgear and open-type switchgear. This type of switchgear is mainly composed of a cabinet body and a circuit breaker. The circuit breaker can be divided into two types: fixed type and handcart type; the cabinet body is composed of a shell, electrical components (including insulating parts), various mechanisms, Composed of secondary terminals and wiring. ...
