There are many types of high-voltage load switches whose structure can be divided into oil-immersed high-voltage load switches, gas-type high-voltage load switches, high-pressure vacuum load switches, air-compressed high-voltage load switches, etc .; according to the operation mode, they can be divided into manual high-voltage load switches and Two types of electric high-voltage load switches. These products are used in power distribution networks, the most popular of which is the high voltage vacuum load switch.
With the reform of urban power grids in China, people are paying more and more attention to high-voltage load switches and other equipment. The following briefly introduces the structural characteristics and principles of two typical high-voltage load switches.
The high-voltage load switch uses the advantages of the arc and the related operating mechanism. Because the high-voltage load switch does not have the ability to cut off the short-circuit current, it is relatively simple in structure. It is suitable for small currents and frequent operating conditions. There are two main types of load switches, outdoor pole type and indoor type.
