Automatic cooling power transformation cabinet

Abstract

The present invention proposes an automatic cooling substation cabinet, which includes a cabinet body, a circulating pump, a refrigeration device, and a controller. A first cooling cavity and a second cooling cavity are respectively arranged in the first support plate and the second support plate, and the Each mounting plate is provided with a third cooling chamber communicating with the first cooling chamber and the second cooling chamber. The first cooling chamber, the second cooling chamber and the third cooling chamber are all filled with cooling liquid, and the circulation pump passes through the first connecting pipe and the second connecting pipe communicate with the first cooling chamber and the second cooling chamber respectively, and the refrigeration device is arranged on the first connecting pipe or the second connecting pipe. Through the mutual cooperation of the controller, N temperature sensors, the circulation pump and the refrigeration device, the present invention realizes automatic cooling and cooling of the cooling liquid in a timely manner, with good cooling effect and fast speed, so that the cooling liquid and the cold and heat exchange in the cabinet are kept in balance. It not only achieves the goal of cooling the cabinet, but also avoids the waste of cooling capacity, and ensures that the electrical components inside the cabinet are in a safe environment.

Description

technical field [0001] The invention relates to the technical field of electrical equipment, in particular to an automatic cooling transformer cabinet. Background technique [0002] Because of its low cost and convenient maintenance, the box-type substation has gradually attracted people's attention, and its application range has become wider and wider. It has gradually replaced substations in various urban and rural areas. Due to the concentrated distribution of multiple devices in the cabinet type substation, the space is small and the heat dissipation is difficult. The substation will release a lot of heat during the working process, which will cause the temperature to rise and affect the reliability of the internal equipment. When the substation works at high temperature for a long time, it may even cause a fire hazard. When the temperature difference between the inside and outside of the cabinet-type substation is too large, it is easy to accumulate moisture, which inc...

AI Technical Summary

Problems solved by technology

The substation will release a large amount of heat during the working process, which will cause the temperature to rise and affect the reliability of the internal equipment. When the substation works at high temperature for a long time, it may even cause a fire hazard.

When the temperature difference between the inside and outside of the cabinet-type substation is too large, it is easy to accumulate moisture, which increases the humidity inside the substation, and the equipment in the cabinet-type substation is eroded by moisture, which affects the working stability and service life, and may even cause short circuits and other hazards to the operator. safety hazard
