Problems solved by technology

[0004] The object of the present invention is to provide a gas-insulated metal-enclosed high-voltage switchgear to solve the problem that the space of each chamber is fixed after the processing of the outer box of the high-voltage switchgear in the above-mentioned background technology, but the space range required by different occasions Different, when the space range is insufficient, the space between components is limited, which makes the heat dissipation efficiency low. The handcart in the handcart room often needs to be pulled out for maintenance and other operations. After use, it is easy to forget to close the cabinet door. pose a dangerous problem

Abstract

The invention discloses a gas-insulated metal-enclosed high-voltage switchgear, which includes a box body, the box body includes an outer shell, a horizontally divided short plate for space separation, and a vertically divided long plate, the vertically divided long plate There are multiple sets of horizontally divided short plates, the vertically divided long plate and the horizontally divided short plate are detachably connected, and the vertically divided long plate and the horizontally divided short plate divide the inner wall of the housing into busbar room, cable room, an instrument room and a handcart room, the handcart room is provided with a movable handcart, the handcart room is provided with an opening, and the opening is provided with a retractable handcart room cabinet door. The body is composed of an outer shell, a horizontally divided short board and a vertically divided long board. When in use, according to the size of the busbar room, cable room, instrument room and handcart room, the horizontally divided short board and the vertically divided long board are used in the outer shell The body is divided to increase flexibility and facilitate the reasonable distribution of the internal space of the box according to the actual situation.

Description

technical field [0001] The invention relates to the technical field of high-voltage switchgear, in particular to a gas-insulated metal-enclosed high-voltage switchgear. Background technique [0002] High-voltage switchgear refers to indoor and outdoor AC switchgear operating in a power system with a voltage of 3kV and above and a frequency of 50Hz and below. It is mainly used for the control and protection of power systems (including power plants, substations, power transmission and distribution lines, and industrial and mining enterprises). When the line fails, the faulty part is quickly removed from the grid, so as to ensure the normal operation of the fault-free part of the grid and the safety of equipment and operation and maintenance personnel. [0003] The high-voltage switchgear is mainly composed of a busbar room, a cable room, an instrument room and a handcart room. After the outer box of the high-voltage switchgear is processed, the space of each room is fixed, bu...
