Embodiment Construction

[0038] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0039] A specific embodiment of the box-type substation of the present invention, such as Figure 1 to Figure 8 As shown, the box body 11 is included, and the inside of the box body 11 is divided into three chambers by a partition 17. A medium-voltage switch cabinet 14 is installed in the switch cabinet room 12, a transformer 15 is installed in the transformer room 13, and a low-voltage cabinet room is installed. In the low-voltage cabinet 16, the electrical parts in the three chambers are installed on the bottom plate 111 of the box body 11 through brackets. The brackets are assembled and welded by angle steel. When an arcing fault occurs in the cable chamber 142 of the cabinet 14, the pressure relief structure 200 is conveniently used for pressure relief. The medium voltage switchgear 14 also includes an air chamber 141. The air chamber 141 is guided ...

Abstract

The invention relates to a gas-insulated switchboard body and a box-type substation. According to the invention, a box body of the box-type substation or the gas-insulated switchboard body is provided with a pressure relief opening, the pressure relief opening is blocked by a pressure relief door which is hinged on the box body or the gas-insulated switchboard body, the pressure relief door is stopped through a stop member when the pressure in the box body or the gas-insulated switchboard body is lower than a set value so as to enable the box body and the gas-insulated switchboard body to be normally used, when an electrical component in the box body or the gas-insulated switchboard body generates a high-temperature high-pressure gas because of an arcing fault, the high-temperature high-pressure gas can impact the pressure relief door so as to enable the pressure relief door to be elastically deformed, the pressure relief door can slide over the stop member after being deformed so as to open the pressure relief opening to discharge the gas in the box body or the gas-insulated switchboard body and achieve a purpose of pressure relief, damages imposed on other electrical components by the high-temperature high-pressure gas are avoided, explosion of the box body or the gas-insulated switchboard body when the internal pressure is high enough is also avoided, and the safety performance is improved.

Description

technical field [0001] The invention relates to an inflatable cabinet body and a box-type substation. Background technique [0002] With the maturity of box-type substation technology, it has quickly become a new direction for urban substation construction due to its advantages of high system integration, small footprint, low engineering cost, and short construction period. Box-type substations are placed on both sides of urban roads. When a short-circuit arcing fault occurs in the primary circuit, high-temperature and high-pressure gas will be generated instantaneously. Due to the narrow space in the box-type substation, if it cannot be released in a short time, other spacers in the box will be damaged. Damage or bursting of the box will cause pedestrian casualties or property losses near the box-type substation. Contents of the invention [0003] The purpose of the present invention is to provide an inflatable cabinet body to solve the technical problem that high temper...
