Centralized substation secondary equipment operating environment control device

Abstract

The invention provides a centralized substation secondary equipment operating environment control device. The centralized substation secondary equipment operating environment control device comprises a refrigeration compressor, a conveying channel, a recycling channel, a plurality of cooling channels and a cooling medium. The conveying channel and the recycling channel are pipelines with one ends open and the other ends closed, are arranged on the two sides of the same screen cabinet respectively and communicate with each other through the open ends, and the side walls, close to the closed ends, of the conveying channel and the recycling channel are correspondingly provided with a plurality of communicating openings. Each cooling channel is a hollow heat conduction pipe and is arranged between adjacent secondary equipment, and the two ends of each cooling channel are connected with the corresponding communicating openings in the conveying channel and the recycling channel to form a communication loop; the refrigeration compressor is arranged on the conveying channel or the recycling channel and drives the cooling medium to flow in each communication loop after being started so as to absorb and take away heat of the secondary equipment. Not only can the heat dissipation problem of the equipment be solved, but also the problems of humidity and particulate matter concentration can be solved, so that the service life of the equipment is maximized, and the performance is optimized.

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
