Waterproof heat dissipation system of capacitor cabinet

Abstract

A waterproof heat dissipation system of a capacitor cabinet disclosed by the present invention comprises a main cabinet body, a partition plate is welded in the main cabinet body, and meshes are uniformly formed in the partition plate. A semiconductor refrigeration device is arranged at the left side of the main cabinet body, a heat conduction copper pipe is welded at the right side of the semiconductor refrigeration device, and a plurality of heat dissipation aluminum sheets are evenly welded to the outer side of heat conduction copper pipe. According to the waterproof heat dissipation system, the heat conduction copper pipe is arranged, the heat dissipation aluminum sheets are evenly welded to the outer side of the heat conduction copper pipe, so that the purpose of conducting cold energy to the heat dissipation aluminum sheets is achieved. A circuit breaker is arranged at the upper portion of a mounting plate, so that a circuit can be disconnected in need. A monitoring module is arranged in the main cabinet body, and the monitoring module is connected with an in-cabinet temperature sensor, a line temperature sensor and a line end pressure sensor in parallel, so that the monitoring purpose is achieved. Signals are transmitted to a remote monitoring computer, a capacitor is electrically connected with an output current monitoring module, and the circuit can be cut off during electric leakage, so that the dustproof and waterproof purposes are achieved.

Description

technical field [0001] The invention relates to the technical field of waterproof and heat dissipation systems, in particular to a waterproof and heat dissipation system for capacitor cabinets. Background technique [0002] Most of the load types in the power system are inductive loads, coupled with the widespread use of power electronic equipment by power companies, the power factor of the grid is low. Low power factor reduces equipment utilization, increases power supply investment, damages voltage quality, reduces equipment service life, and greatly increases line loss. Therefore, by connecting the capacitor compensation cabinet in the power system, the inductive load can be balanced, the power factor can be improved, and the utilization rate of the equipment can be improved. [0003] However, the existing capacitor compensation cabinets generally have the defect of poor heat dissipation. Traditional cabinets generally use fans for heat dissipation, but it is easy to cau...

Problems solved by technology

[0003] However, the existing capacitor compensation cabinets generally have the defect of poor heat dissipation. Traditional cabinets generally use fans for heat dissipation, but it is easy to cause a lot of dust inside the cabinet, and the waterproof performance is poor, which will reduce the service life of the cabinet. Accidents are caused. If a fully enclosed cabinet is used, although it can prevent dust from entering, it will cause the internal temperature of the cabinet to rise continuously. Now there is a lack of a cabinet that has good heat dissipation performance and can prevent dust and water.
