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-low voltage complete electrical cabinet which comprises a cabinet body, a switch assembly and a pressure relief assembly. The cabinet body comprises a vertically arranged side plate and a horizontally arranged top plate, electrical equipment is arranged in the cabinet body, the switch assembly comprises a switch cylinder, an elastic film, a contact switch, a contact and a connecting rod, the pressure relief assembly comprises a pressure relief cylinder, a rotating plate, a middle rod and a limiting mechanism, the limiting mechanism comprises a clamping cover, a clamping block, a sleeve, a first spring and a first electromagnet, raised air pressure and flames in the cabinet body are sprayed to the outside above through the pressure relief barrel, pressure is relieved in time, high-pressure gas and flame are exhausted above the cabinet body, so that impact on the horizontal surrounding environment of the cabinet body can be reduced, and theexplosion loss is reduced, impact on other parts of the cabinet body caused by explosion of the electrical cabinet can be reduced, and impact force generated by explosion can be reduced, therefore, damage of explosion to surrounding people or objects is reduced, and the purpose of explosion prevention is achieved.

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 ...
