Abstract

The invention relates to a high-voltage cabinet with a long service life. Supporting legs are mounted on the bottom surface of a base; a high-voltage cabinet is mounted at the top end of the base; themiddle part of one side of the high-voltage cabinet is connected with an air inlet of a fan through a pipe; a fan air supply outlet is communicated with a sealing box through a pipe; a first baffle is obliquely installed at the side, away from a fan, in the sealing box, and a groove is formed in the end of the first baffle; a rotating shaft is horizontally installed in the groove, and three second baffles are installed on a shaft body of the rotating shaft. According to the invention, the air in the high-voltage cabinet is circularly pumped into the sealing box through the fan; after being dehumidified by a desiccant, the air is sent into the cabinet body again; the desiccant can be automatically replaced through the mutual cooperation of the multiple baffles and the springs in the sealing box, the multiple desiccant can be stored in the feeding port at a time, the contact area between the desiccant and air is increased through the cylindrical desiccant, and the utilization rate of the desiccant is more sufficient.

Description

technical field [0001] The invention relates to a high-voltage cabinet with high service life. Background technique [0002] The high-voltage cabinet is a cabinet that is used for on-off, control or protection in the power generation, transmission, distribution, power conversion and consumption of the power system. Because it contains a large number of electrical components inside, its moisture-proof and dehumidification performance must be excellent. The high humidity in the body causes electrical accidents such as short circuits. The current high-voltage cabinets mostly rely on the built-in desiccant for dehumidification. Desiccant, and the relatively compact environment in the cabinet when there are a large number of installed components is not suitable for such placement, and because the high-voltage circuit inside the cabinet is extremely dangerous, it generally needs to be replaced when the desiccant fails. It is troublesome and affects production, and there is great ...
