A centralized substation secondary equipment operating environment control device

Abstract

The invention provides a centralized substation secondary equipment operating environment control device, which includes a refrigeration compressor, a conveying channel, a recovery channel, a plurality of cooling channels and a cooling medium; both the conveying channel and the recovery channel are pipes with one end open and one end closed It is arranged on both sides of the same screen cabinet, and the two are connected through the open end, and there are multiple conduction ports on the side walls near the closed end of the two; each cooling channel is a hollow heat pipe and is respectively arranged on the corresponding Adjacent to the secondary equipment room, its two ends are connected to the corresponding conduction ports on the conveying channel and the recovery channel to form a communication circuit; the refrigeration compressor is set on the conveying channel or the recovery channel, and drives the cooling medium every It flows in a connected circuit to absorb and take away the heat from the secondary equipment. The implementation of the present invention can not only solve the heat dissipation problem of the equipment, but also solve the problems of humidity and particle concentration, so as to maximize the operating life and optimize the performance of the equipment.

Description

technical field [0001] The invention relates to the technical field of substation operating environment control, in particular to a centralized substation secondary equipment operating environment control device. Background technique [0002] Secondary equipment is the core equipment to realize remote sensing and dynamic management of substations, and its operating conditions depend on the technical requirements and production processes of its products. What is certain is that a stable and good operating environment can make the secondary equipment operate in better condition, which is conducive to optimizing performance and extending operating life. [0003] The centralized arrangement of substation secondary equipment refers to the centralized installation of multiple secondary equipment with different functions, and they are arranged at the same place with the smallest possible distance (such as less than 20mm). At this time, the operating environment under the centraliz...

AI Technical Summary

Problems solved by technology

[0004] At present, in the existing centralized layout of secondary equipment, due to the consideration of the electrostatic impact of particulate matter on the integrated circuit of the equipment, the secondary equipment is usually designed as a fully enclosed type, and adopts a self-cooling and heat dissipation method (that is, through the air and the equipment shell). heat conduction for heat dissipation), although it can prevent particles from directly adhering to the integrated circuit, but the heat dissipation effect of heat conduction is extremely poor, which greatly reduces the operating life of the equipment and shortens the mean time between failures of the equipment

At the same time, due to the humidity and particle concentration determined by the external natural environment, in a non-closed operating environment, fully enclosed secondary equipment is also prone to moisture in rainy days or when returning to the south. Once the particles are seriously attached, the internal integrated circuits of the secondary equipment are prone to short circuits failure, resulting in damage to equipment performance
