Description

Technical Field

[0001] This invention relates to the field of dehumidification and humidity control technology, and in particular to low-carbon and energy-saving dehumidification and humidity control methods and systems for substation operating environments. Background Technology

[0002] A substation, also known as a transformer station, is a location in a power system that transforms voltage and current, receiving and distributing electrical energy. It uses equipment such as transformers to convert high-voltage electrical energy into low-voltage electrical energy for use by various users. At the same time, substations are also responsible for aggregating multiple power sources and redistributing them to a wide range of users, improving the reliability of power supply.

[0003] Many electrical switchgear devices in substations rely on air gaps for insulation. If the ambient humidity is too high, the insulating properties of air decrease, and moisture in the air adheres to the surface of the insulating material, reducing the insulation resistance of the electrical equipment. In areas with accumulated dust and grime, the moisture level is even more severe, further lowering the insulation resistance and making insulation breakdown more likely, thus causing equipment failure.

[0004] Meanwhile, a humid environment can easily cause corrosion of conductive metals and metal casings, reducing equipment performance and lifespan. Furthermore, moisture can penetrate the equipment's interior, causing problems such as short circuits on circuit boards and insulation aging. These phenomena can lead to equipment malfunctions, and in severe cases, trigger large-scale power system failures, increasing the frequency of maintenance and replacement, and consequently raising operating costs.

[0005] Therefore, how to control the humidity environment of substations and match the humidity with the dehumidification power to achieve low-carbon and energy-saving effects is an urgent problem to be solved.
