Plane installation structure and installation method of control cabinet in GIS combined electrical apparatus

Abstract

The present invention relates to the technical field of high, medium and low voltage power transmission and transformation equipment, in particular to a plane installation structure and an installation method of a control cabinet in a GIS combined electrical apparatus. The plane installation structure of the control cabinet in the GIS combined electrical apparatus comprises a left column and a right column and is characterized in that the left side of the left column is connected with a left fixing plate through a first rotating shaft; the right side of the right column is connected with a right fixing plate through a second rotating shaft; the upper parts of the left column and the right column are connected through a crossbeam; the lower parts of the left column and the right column areconnected through a plug-in plate; and an air switch panel, an indicator installation board, an analog line installation board and a change-over switch installation board are sequentially connected between the left column and the right column from top to bottom through snap joint. Compared with the prior art, the assembly is simple; the assembly efficiency is greatly improved; a large number of wires and terminals used for transition among different planes in the prior art are saved; and the wire cost is reduced.

Description

technical field [0001] The invention relates to the technical field of high, medium and low voltage power transmission and transformation equipment, in particular to a planar installation structure and installation method of a control cabinet in a GIS combined electrical appliance. Background technique [0002] At present, the structure of the mainstream control cabinet in China is mainly three-dimensional arrangement, and the components on the panel and the terminals in the cabinet are mostly not on the same plane. Although this design can install various components, the disadvantages are obvious: 1. The excessive distance between components and terminals causes a lot of waste of wires, and the complex structure makes the calculation of wire length inaccurate, which increases a lot of redundancy; 2. Wiring workers need to drill from the back of the cabinet to wire in the cabinet. Limitations not only reduce the efficiency of wiring, but also affect the physical and mental h...

[0002] At present, the structure of the mainstream control cabinet in China is mainly three-dimensional arrangement, and the components on the panel and the terminals in the cabinet are mostly not on the same plane. Although this design can install various components, the disadvantages are obvious: 1. The excessive distance between components and terminals causes a lot of waste of wires, and the complex structure makes the calculation of wire length inaccurate, which increases a lot of redundancy; 2. Wiring workers need to drill from the back of the cabinet to wire in the cabinet. Limitation, not only reduces the efficiency of wiring, but also affects the physical and mental health of workers

The disadvantages of the other frame structure are: 1. The components installed on the door panel and the components in the cabinet need to be installed separately, and the wiring efficiency is not high; 2. The wires between the components on the door panel and the components in the cabinet can only be connected by the door. The wiring on the shaft side, the wiring method is single and the length of the wire is not easy to control, resulting in waste of wires
