Self-opening-closing moisture absorption type high-voltage switch cabinet

Abstract

The invention discloses a self-opening-closing moisture absorption type high-voltage switch cabinet, which belongs to the field of switch cabinets, and is characterized in that when the environment temperature is higher, an outer self-opening-closing sheet expands outwards to drive moisture absorption beads to be far away from selection vent holes, and meanwhile, a pre-splitting ball is split, sothat the outer self-opening-closing sheet is internally and externally transparent; at the moment, high-heat air in a cabinet body can overflow outwards along the selection vent holes and the pre-splitting ball, so that the effect of assisting heat dissipation holes in dissipating heat of the cabinet body is achieved, the heat dissipation efficiency is remarkably improved, when the environment temperature is low, the outer self-opening-closing sheet contracts, the moisture absorption beads block the selection vent holes, and heat generated in the cabinet body can be prevented from overflowingoutwards; according to the invention, the temperature of the whole cabinet body is kept relatively high relative to the environment, moisture in the cabinet body can also be adsorbed, the probabilityof condensation is significantly reduced, the opening and closing of the selection vent holes are realized through movement of the moisture absorption ball in the selective vent holes, and the heat dissipation and moisture absorption efficiency is further improved.

Description

technical field [0001] The invention relates to the field of switch cabinets, in particular to a self-opening and closing moisture-absorbing high-voltage switch cabinet. Background technique [0002] The switch cabinet is a kind of electrical equipment. The external line of the switch cabinet first enters the main control switch in the cabinet, and then enters the sub-control switch, and each branch is set according to its needs. Such as instruments, automatic controls, motor magnetic switches, various AC contactors, etc., some also have high-voltage room and low-voltage room switch cabinets, high-voltage busbars, such as power plants, etc. load shedding. [0003] The main function of switchgear is to switch, control and protect electrical equipment during the process of power generation, transmission, distribution and power conversion in the power system. The components in the switch cabinet are mainly composed of circuit breakers, disconnectors, load switches, operating ...

AI Technical Summary

Problems solved by technology

[0004] When the electrical components inside the switchgear are running, they will generate a lot of heat. However, in the prior art, heat dissipation holes are usually provided on the side and back of the electrical cabinet. However, due to the high heat generated by the electrical components, the ambient temperature is also very high in summer. In the case of high temperature, only the setting of cooling holes obviously cannot meet its heat dissipation requirements. In winter, when the temperature is low, condensation is prone to occur in the switch cabinet, resulting in the electrical components in the switch cabinet being easily damaged.
