Description

Technical Field

[0001] The utility model relates to the technical field of electric control cabinets, in particular to an anti-condensation device for an electric control cabinet. Background Art

[0002] With the continuous development of society, people's living standards are getting higher and higher, and electrical equipment has begun to enter people's lives, which has made electrical control cabinets quite popular. Electrical control cabinets are convenient and reliable, and can easily replace manual labor to perform semi-intelligent electrical control. However, electrical control cabinets will also face the problem of condensation. Affected by external conditions, condensation is very likely to occur, causing the electrical control cabinet to become disabled due to cold, or even cause permanent damage, so anti-condensation devices have appeared;

[0003] Announcement No. "CN207399745U" is an anti-condensation device for an electrical control cabinet, comprising an antifreeze storage cylinder, a capacity display tube is arranged on the front side wall of the antifreeze storage cylinder, a top cover is arranged just above the antifreeze storage cylinder, a handle is connected to the top of the top cover, an antifreeze adding port is arranged on the upper left part of the antifreeze storage cylinder, and a sampler is arranged below the antifreeze adding port. The anti-condensation device is equipped with a replacement box, and a one-way valve is arranged inside the replacement box. The one-way valve allows the antifreeze to enter but not exit according to the air pressure principle. In this way, the operator only needs to release the antifreeze with a large density and has expired from the drain pipe, and then add new antifreeze from the small inlet. The antifreeze flows into the antifreeze storage cylinder through the one-way valve, thus realizing partial replacement of the antifreeze, and solving the problem that the anti-condensation device of the traditional electrical control cabinet can only be replaced once, resulting in waste of resources.

[0004] The anti-condensation device reduces the waste of resources by partially replacing the antifreeze, but the anti-condensation device cannot control the usage rate of the antifreeze when in use. If the antifreeze is used all the time, it is easy to cause waste of the antifreeze, which is not conducive to improving the applicability of the anti-condensation device. Therefore, we propose that the anti-condensation device of the electrical control cabinet can well solve the above problems. Utility Model Content
