The importance of high voltage switchgear equipment

With the development of society and economy, electric energy becomes more and more important, which requires the stable operation of power system. In the current power system, the application of high voltage switchgear is very extensive, which effectively ensures the normal operation of the power grid. But the application of high voltage distribution switchgear is not foolproof, there are some problems, and it caused a great hidden danger to the reliable operation of the power system, but also bring huge economic losses. Therefore, the power department should fully realize the safety management of the high voltage switchgear, improve its operating environment, strengthen the patrol inspection, and ensure the reliability of the high voltage switchgear equipment.

Main components of high voltage switch cabinet: switchgear, measuring instruments, protection circuit, connecting bus and related auxiliary equipment to receive and distribute power. According to the design scheme, connecting equipment can effectively control generators, transformers and various lines.

The main electrical equipment of the high voltage switchgear is the high voltage circuit breaker. According to the different installation methods, it can be divided into the following two kinds: fixed type and open type. Fixed, all kinds of electrical accessories (including load switch, etc.) are installed in the position of the cabinet fixed device, more simple, low cost, no isolation contact, not easy to have problems caused by bad contact, such as high temperature decomposition. But the disadvantage is that the position of the cabinet is too high, the operation is not convenient, and it is not very convenient in the follow-up maintenance process. Mobile open type is a collection of various electrical accessories, such as high voltage circuit breaker, and it is installed in the mobile car, easy to operate.

High voltage switchgear generator switchgear plays a very important role in the power system and is effectively controlled and protected in the process of transportation and sales. However, in the actual operation, there are many common problems of the high voltage switchgear, which affect the reliable operation of the power system, and even cause some serious security risks. We should try our best to manage the operation of high voltage switchgear to ensure its reliable operation.
