Embodiment Construction

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0034] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relationship between the components in a certain posture (as shown in the accompanying drawings). Relative positional relationship, movement conditions, etc., if the specific posture changes, the directional indication will also change accordingly.

[0035] In addition, in t...

Abstract

The invention discloses an explosion-proof high and low voltage complete electrical cabinet, which comprises a cabinet body, a switch assembly and a pressure relief assembly; the cabinet body includes a vertically arranged side plate and a horizontally arranged top plate; the inside of the cabinet is used for arranging electrical equipment ; The switch assembly includes a switch cylinder, an elastic membrane, a contact switch, a contact and a connecting rod; the pressure relief assembly includes a pressure relief cylinder, a rotating plate, a middle rod and a limit mechanism; cover, clamping block, sleeve, first spring and first electromagnet; the rising air pressure and flame in the cabinet are sprayed out to the upper outside through the pressure relief cylinder, and the pressure is released in time; the high-pressure gas and flame are discharged to the inside of the cabinet. Above, it can also reduce the impact on the surrounding environment of the cabinet level and reduce the explosion loss; it can also reduce the impact on other parts of the cabinet caused by the explosion of the electrical cabinet, and reduce the impact force caused by the explosion; thus reducing The damage caused by the explosion to the surrounding people or objects, in order to achieve the purpose of explosion protection.

Description

technical field [0001] The invention relates to the technical field of electrical equipment, in particular to an explosion-proof high and low voltage complete electrical cabinet. Background technique [0002] High-voltage and low-voltage complete sets of electrical cabinets are equipment connected to high-voltage or low-voltage cables. Generally, power plants, power supply bureaus, and substations use high-voltage electrical cabinets, which are then stepped down by transformers to low-voltage electrical cabinets, and then to various uses. Electric distribution box, high and low voltage complete set of electrical cabinets mainly integrate some electrical equipment such as switch circuit breakers, disconnectors, lightning arresters, grounding knives, and current transformers. [0003] There are multiple chambers inside the existing high and low voltage complete sets of electrical cabinets. Since the electrical equipment in the cabinets will generate heat during use, excessive ...
