Moisture-proof air circuit breaker installation box

Abstract

The invention discloses a moisture-proof air circuit breaker installation box which comprises a box body. One side of the box body is provided with a through groove. The through groove penetrates the box body and extends to the other side of the cable body. The through groove is provided therein with a dehumidification device in connection with the through groove in a sliding motion manner. Due to the arrangement of a sliding groove and a through groove, the dehumidification device can be installed in the installation box conveniently. For the cooperation of the motor, the support base and the blades, the moistening air rises and at the same time, through the arranged ventilation hole, the air inside the installation box is made in a circulation state so that the water steams in the air are not concentrated into small water beads. Through the arrangement of a first through hole and a first placing layer, the moistening air inside the box body enters the dehumidification installation plate where raw lime powder absorbs the moistening air. And through a second through hole, the activated carbon and a second placing layer, the remaining water steams are completely absorbed by the activated carbon and the dry air enters the installation box through a third through hole. Therefore, a dehumidification effect can be achieved.

Description

technical field [0001] The invention relates to the technical field of electrical equipment, in particular to a moisture-proof air circuit breaker installation box. Background technique [0002] The air circuit breaker is a commonly used circuit device. It is installed in the circuit to protect the safety of the circuit. When the current of the circuit exceeds the rated current, the air circuit breaker will disconnect the circuit to prevent electrical damage or damage caused by overload. A fire is caused by a short circuit. Air circuit breakers are generally installed in an installation box to prevent damage caused by exposure to the outside. However, the air circuit breaker installation boxes on the market today have poor moisture-proof effects. It condenses into small water droplets. If these small water droplets adhere to the circuit, it will cause a short circuit in the circuit and cause the air circuit breaker to trip. Contents of the invention [0003] The purpose o...
