Embodiment Construction

[0018] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is carried out on the premise of the technical solution of the present invention, and detailed implementation and specific operation process are given, but the protection scope of the present invention is not limited to the following embodiments.

[0019] A switchgear with disconnectable busbar connections, such as figure 1 As shown, it includes a switch cabinet body 3 and a trolley switch 1. The switch cabinet also includes a linkage mechanism 7 and a travel switch 5. The switch cabinet bus bar 4 in the switch cabinet body 3, and one end of the switch cabinet bus bar 4 passes through the travel switch 5 and the travel switch 5. The grounding busbar 6 is connected, and the other end is connected to the trolley switch 1, and the trolley switch 1 is connected to the travel switch 5 through the linkage mechanism 7;

Abstract

The invention relates to a disconnectable switch cabinet of a busbar connection portion. The switch cabinet comprises a switch cabinet body and a dolly switch. The switch cabinet also comprises a linkage mechanism and a stroke switch. A switch cabinet busbar is arranged in the switch cabinet body. One end of the switch cabinet busbar is connected to a grounding busbar through the stroke switch and the other end is connected to the dolly switch. The dolly switch is connected to the stroke switch through the linkage mechanism. When the dolly switch is pushed to an overhauling position, a linkage mechanism drives the stroke switch to disconnect the connection between the switch cabinet busbar and the grounding busbar. Compared to the prior art, by using the switch cabinet of the invention, the switch cabinet busbar and the grounding busbar are designed to be connected through the stroke switch; through the linkage mechanism, when the dolly switch is pushed to the overhauling position, the stroke switch automatically disconnects the connection between the switch cabinet busbar and the grounding busbar so that a personal safety accident generated because work personnel opens an isolation baffle plate without permission is avoided.

Description

technical field [0001] The invention relates to safety electrical technology, in particular to a switchgear with a disconnectable busbar connection part. Background technique [0002] In recent years, there have been many personal injury accidents caused by electric shock of switch cabinets in the power system. Most of the electric shocks are caused by workers accidentally touching live parts of switch cabinets. During the overhaul of the switchgear, after the handcart switch of the switchgear is shaken to the overhaul position, the rear isolation baffle of the switchgear will be reliably closed as required, but during the overhaul process, due to various reasons, the staff may separate and isolate without authorization. In the switchgear, the trolley switch is located in front of the switchgear, and the busbar and the static contact fixedly connected to the busbar are located at the back of the switchgear. The two parts are isolated by the isolation baffle. When the trolley...
