Problems solved by technology

After research, it is found that the condensation problem is the main cause of the failure of the power distribution cabinet, and seriously affects the reliability of the power supply of the equipment
[0003] When the electrical cabinet is outdoors, when the temperature difference is large, it is easy to generate condensation, which will cause corrosion to the equipment, reduce the resistance of the circuit, and even short circuit in severe cases
At present, most electrical cabinets are equipped with dew heating devices or dehumidifiers. However, the working environment of outdoor electrical cabinets has a lot of water vapor, and condensation occurs from time to time, and dew heating devices or dehumidifiers remove more moisture in the electrical cabinets. Water vapor, energy consumption is large

Abstract

The invention relates to a mine locomotive rectifier cabinet, belongs to the field of electrical equipment, and provides an autonomous dehumidifying device of an electrical cabinet. A technical schemeis as follows: the mine locomotive rectifier cabinet comprises a cabinet body, condensation points, a water tank and a water return hole; several condensation points are arranged on the inner wall ofthe cabinet body; the condensation points are convex metal points; the water tank is arranged on the lower end of the cabinet body along the inner wall; the water tank is arranged in an inclined manner; and the water return hole is arranged at the lowest point of the water tank.

Description

technical field [0001] The invention relates to a mine locomotive rectifier cabinet, which belongs to the field of electrical equipment. Background technique [0002] With the rapid development of the economy, the use of cable power supply in urban networks has become an inevitable trend in the development of distribution networks. From the perspective of cabled power supply, power supply has become the preferred form of cabled distribution network because of its economy and reliability. While electrical cabinets are widely used, the occurrence of equipment failures also increases. After research, it is found that the condensation problem is the main cause of the failure of the power distribution cabinet, and seriously affects the reliability of the power supply of the equipment. [0003] When the electrical cabinet is outdoors, when the temperature difference is large, it is easy to generate condensation, which will cause corrosion to the equipment, reduce the resistance ...
