Description

Technical Field

[0001] The utility model relates to the technical field of dustproof compensation cabinets, in particular to a low-voltage reactive compensation cabinet. Background Art

[0002] Low-voltage reactive power compensation cabinet is a technology that improves the power factor of the power grid in the power supply system, reduces the loss of power supply transformers and transmission lines, improves power supply efficiency, and improves the power supply environment. Therefore, reactive power compensation plays an indispensable and important role in the power supply system. Reasonable selection of compensation devices can minimize network losses and improve the quality of the power grid.

[0003] However, at present, there are many wires used inside the main body of the low-voltage reactive compensation cabinet, so there will be a disorderly phenomenon, which affects the later maintenance. In addition, the main body of the low-voltage reactive compensation cabinet is generally in a closed state, and its temperature will be high. If the temperature is high, it will cause damage to the internal components.

[0004] Therefore, it is particularly important to choose a reasonable heat dissipation method. Nowadays, water cooling is more commonly used to cool the compensation cabinet, but low-temperature water can only flow in a sealed channel and then cool the air in the surrounding environment, but cannot actively contact the electrical components in the compensation cabinet, so the cooling effect is limited. If it works with a fan, more dust will enter the compensation cabinet during the operation of the fan. The accumulation of dust will cause the heat dissipation inside the compensation cabinet to deteriorate, and most electrical racks are fixedly installed, which is inconvenient for disassembly and maintenance. For this reason, we propose a low-voltage reactive compensation cabinet. Utility Model Content
