Moisture-proof device for power switch cabinet

Abstract

The invention provides a moisture-proof device of a power switch cabinet. The moisture-proof device comprises a shell, a cabinet body, a first air pipe, a second air pipe, a supporting rod, a spherical shell and a liquid discharging pipe, wherein a partition plate is arranged in the shell; a first humidity sensor is arranged in the shell; the cabinet body is arranged on the partition plate; the first air pipe is arranged on the second air pipe, and an air blowing fan is arranged in the first air pipe; the second air pipe is arranged on the inner wall of the cabinet body, a third air pipe is arranged on the outer wall of the left end of the second air pipe, a first one-way ventilation assembly is arranged in the second air pipe, and a second one-way ventilation assembly is arranged in the third air pipe; the spherical shell is arranged on the supporting rod, and a refrigeration mechanism is arranged in the spherical shell; the liquid discharging pipe is arranged on the second air pipe, and an electromagnetic valve is arranged on the liquid discharging pipe; and a second humidity sensor is arranged in the cabinet body, and a control system is arranged in the cabinet body. According to the invention, the height of the cabinet body is increased, so the influence of bottom moisture on the interior of the cabinet body is reduced; and the blowing fan and the electromagnetic valve circularly work to discharge liquefied liquid, so the problem of overhigh humidity in the cabinet body can be fundamentally solved.

Description

technical field [0001] The invention relates to the technical field of moisture-proof devices, in particular to a moisture-proof device for a power switch cabinet. Background technique [0002] Nowadays, for the sake of beauty in cities and residential areas, power distribution lines often use power facilities such as cables, ring network cabinets, and switching stations. closed. The environment of this kind of place is closed and dark, the air is not easy to convect, and it is easy to gather moisture. When the relative humidity exceeds a certain level, a large amount of condensation will be generated, which will gradually cause a series of serious damage to the power equipment and become an important cause of equipment failure in the power switch cabinet. . The existing power switchgear has poor moisture-proof performance. The harsh wet and hot environment can easily lead to water vapor in the power switchgear, and the condensation of water vapor will cause condensation. ...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the technical problems existing in the background technology, the present invention proposes a moisture-proof device for power switch cabinets. The lifting components are activated, and the cabinet body is driven up through the partition to raise the height of the cabinet body and reduce the influence of moisture at the bottom on the cabinet body. In addition, the blowing fan and solenoid valve work in a cycle to discharge the liquefied liquid, which can fundamentally solve the problem of excessive humidity in the cabinet
