Problems solved by technology

There are also pressure relief plates made of glass fiber reinforced plastic or acrylic, but the former is easy to cause dust to fall into the high-voltage vacuum high-voltage switchgear, and the latter is washed away under the strong pressure of high-temperature and high-pressure gas, and it will fly randomly in the power distribution room and be easily injured. Or smash other equipment, or even cause injury to the staff on duty

Embodiment 1

[0025] This embodiment provides a removable AC metal-enclosed switchgear, the structure of which is as follows: Figure 1-Figure 3 as shown,

[0026] Including a cabinet 1, the cabinet 1 is divided into a busbar room 12, a circuit breaker room 13, and a cable room 14 by a partition 11. It is characterized in that: a pressure release port 2 is opened on the cabinet 1, and the A pressure release valve 3 is provided on the pressure release port 2 , the pressure release valve 3 includes a base plate 31 hinged on the cabinet body 1 , and the base plate 31 closes the pressure release port 2 . The pressure release port 2 is provided with a magnet 21, and the substrate is made of a metal material attracted by the magnet. The base plate 31 is provided with an auxiliary door 32, and an auxiliary release port 321 is opened on the side of the auxiliary door 32, and a pressure relief chamber 33 is arranged in the pressure release valve 3, and the auxiliary release port 321 passes through ...

Embodiment 2

[0031] A removable AC metal-enclosed switchgear, such as figure 1 As shown, including the cabinet body 1, the shell of the cabinet body 1 is completely closed and grounded. The inside of the cabinet is divided into independent spaces with various functions by partitions 11, such as a busbar room, a circuit breaker room 13, and a cable room 14.

[0032] Among them, the cabinet body 1 is made of zinc-aluminum-magnesium steel plate or aluminum-zinc-coated steel plate, which is processed by a double bending process, thereby increasing the strength of the cabinet body. The whole cabinet body, such as the door and terminal sealing plate, is sprayed with epoxy resin powder to form an epoxy resin layer to increase the anti-corrosion and anti-oxidation performance of the cabinet body.

[0033] Due to the operation of the bus in the bus room, the temperature in the bus room is relatively high, so the parts in the bus room are sprayed with matt black paint to form a matt protective laye...

Abstract

The invention discloses a movable-type alternating current metal sealing switch cabinet and relates to the technical field of safe structures of power distribution cabinets. The movable-type alternating current metal sealing switch cabinet includes a cabinet body, and the interior of the cabinet body is divided into a bus chamber, a breaker chamber and a cable chamber through clapboards; a pressure release opening is formed in the cabinet body, a pressure release valve is arranged on the pressure release opening and includes a baseplate, and the baseplate is hinged to the cabinet body and usedfor sealing the pressure release opening. By means of the scheme, the safety of the movable-type alternating current metal sealing switch cabinet is improved, and the service life of the movable-typealternating current metal sealing switch cabinet is further prolonged.

Description

technical field [0001] The invention relates to the technical field of safety structures of power distribution cabinets, in particular to a removable AC metal-enclosed switch cabinet. Background technique [0002] At present, some small high-voltage switchgears are semi-closed high-voltage switchgears, that is, a certain ventilation and heat dissipation position is set, but in order to ensure that they are not disturbed by external factors, the apertures of the ventilation and heat dissipation holes or the shutters are relatively small. When the high-voltage switchgear is in operation due to circuit short circuit, insulation aging or human operation error, etc., the short circuit fault of the primary circuit occurs, under the short circuit current of tens of thousands of amperes, the instantaneous high temperature and high pressure gas cannot flow in the narrow cabinet. Effective release in a very short period of time may cause the high-voltage switchgear to burst, resulting...
