Description

Technical Field

[0002] Substation, also known as transformer station, is a place in the power system that transforms voltage and current, receives and distributes electric energy. It converts high-voltage electric energy into low-voltage electric energy by using transformers and other equipment for various users. At the same time, the substation is also responsible for collecting multiple power sources and redistributing them to the majority of users to improve the reliability of power supply.

[0003] Many electrical switchgear in substations rely on air gaps for insulation. If the ambient humidity is too high, the insulation performance of the air will be reduced, and at the same time, the moisture in the air adheres to the surface of the insulating material, which will reduce the insulation resistance of the electrical equipment. In places where dust and dirt are accumulated, the humidity will be more serious, the insulation resistance will be lower, and it is more likely to cause insulation breakdown, thereby causing equipment failure.

[0004] At the same time, a humid environment can easily cause corrosion of conductive metals and metal casings, reducing equipment performance and service life. In addition, moisture can penetrate into the interior of the equipment, causing problems such as circuit board short circuits and insulation aging. These phenomena may cause equipment failures, and in severe cases, cause large-scale failures in the power system, increase the frequency of maintenance and replacement, and thus increase operating costs.
