The high-voltage transformer bushing is a key insulating and connecting component in the high-voltage transformer, and is responsible for the electrical connection between the high-voltage coil and the external power grid. It not only ensures the reliable transmission of the current inside the transformer, but also plays an important role in insulation protection, preventing the…
SF6 circuit breaker, referred to as GCB for short, is an air-blown circuit breaker. Its characteristic is that the working air pressure is low. During the arc blowing process , the gas is not discharged to the atmosphere, but is recycled in the sealed system. Due to the good insulation performance and arc extinguishing performance…
What is GIS equipment GIS is the English abbreviation of Gas Insulated Switchgear. It is generally translated as gas insulated fully enclosed combined electrical appliances. SF6 gas is usually used as the insulating medium, including circuit breakers (CB), isolating switches (DS), grounding switches (ES, FES), busbars ( BUS), current transformer (CT), voltage transformer (VT), lightning…
In today’s high-voltage power systems, zinc oxide arresters play a vital role. Its practicality lies in its ability to effectively protect power equipment from damage caused by lightning overvoltage and operating overvoltage, thereby ensuring the stable operation of the power system. Zinc oxide arrester is a special arrester that uses zinc oxide, a material with…
Overview In the power system, transmission lines are the components with the most failures. Therefore, how to improve the reliability of transmission lines is of great significance to the safe operation of the power system. The nature of transmission line faults is that most of them are transient faults, accounting for about 80% to 90%…
1. How is the structure of the insulator? What is its function? answer: An insulator (commonly known as a porcelain bottle) is composed of a porcelain part and a hardware part, and the middle part is glued with cement adhesive. The porcelain part is to ensure that the insulator has good electrical insulation strength, and…
Composite insulators are currently used in a huge amount, but when the mandrel process is not well controlled, defects will be left, and string breaks and breakdown faults will continue to develop during operation. In order to eliminate the fault in the bud, the diagnosis of composite insulator mandrel defects is very important. For the…
