Energy-saving anti-freezing power distribution cabinet

Abstract

The invention discloses an energy-saving anti-freezing power distribution cabinet. The power distribution cabinet comprises a base, a box body, a sliding rail, a box door, a sealing strip, a temperature controller, solar heat collectors, a solar tracking device, a heat circulating fan, a circulating pump, an embedded control panel, a temperature control switch, a door lock, a water tank, a heat circulating pipeline and a heat preservation material. Interlayers are arranged in the box body and the box door, heat circulation pipelines are arranged in the interlayers, internal circulation mediumwater of the heat circulation pipelines comes from the water tank, and after being heated by the solar heat collectors arranged at the top and on the side faces, the internal circulation medium watercirculates in the whole pipelines under the driving of the circulation pump to heat the whole box body. The circulating fan and the temperature controller are arranged in the box door and connected with the control switch and the control panel on the box door, and the sealing strip is arranged on the periphery of the box door. When external weather is cold and the temperature is too low, the temperature controller can control a circulating device to carry out heat circulation according to the surrounding environment and the internal temperature, it is guaranteed that the box body and the box door cannot be frozen, and electrical elements in the box cannot be damaged.

Description

technical field [0001] The invention relates to a power distribution cabinet of a power system, more specifically, it relates to an energy-saving antifreeze power distribution cabinet suitable for use in severe cold weather. Background technique [0002] At present, the power distribution cabinets on the market generally include a box body and a box door, and most of them are single-layer structures. This kind of power distribution cabinet can be used normally in a normal temperature environment, but when used outdoors in severe cold seasons or in northern regions, affected by rain and snow, the outside and around the cabinet door are very easy to freeze, resulting in the door being unable to open, and even the cabinet body freezing. Cracks, damage to internal electrical components and other serious consequences. [0003] In recent years, there has also been an antifreeze technology that makes the box into a sandwich, installs a thermal fluid inside and heats the heating el...

Problems solved by technology

This kind of power distribution cabinet can be used normally in a normal temperature environment, but when used outdoors in severe cold seasons or in northern regions, affected by rain and snow, the outside and around the cabinet door are very easy to freeze, resulting in the door being unable to open, and even the cabinet body freezing. Cracks, damage to internal electrical components and other serious consequences

[0003] In recent years, there has also been an antifreeze technology that makes the box into a sandwich, installs a thermal fluid inside and heats the heating element immersed in the thermal fluid to increase the temperature of the box, but due to its large energy consumption, the operating cost is high , and the tightness requirements for the sandwich structure of the box body are relatively high, once leakage occurs, it may cause dangerous consequences
