High voltage load switch is a kind of load switch, which is mainly used for products in high voltage lines. The main classifications can be divided into six categories. 1. Gas-producing high-voltage load switch: The arc chamber of this switch is equipped with materials capable of generating gas. When the arc is disconnected, a certain amount of energy will be generated by the high-voltage line. Blow out the arc.

2. Piston high-voltage load switch: There is a piston system inside. During the switching process, the piston generates gas and blows out the arc. 3. Compressed air high pressure load switch: The principle is similar to that of compressed air high pressure load switch, but the source of gas is mainly compressed air. 4.SF6 gas high voltage load switch: The principle is similar to that of the compressed gas high voltage load switch. The gas is SF6 gas instead of air. This type of gas has a better effect on high-performance circuit disconnection than the above two. 5. Oil decomposition high-voltage load switch: The principle is similar to the first one, but the gas-generating material does not need to be prepared by itself, but the arc is decomposed by the gas decomposed by the oil in the line. The energy of the decomposed oil also comes from the arc interrupt To generate energy. 6. Vacuum high-voltage load switch: The use of the characteristics of the arc can not exist in a vacuum environment, so that a relatively vacuum environment inside the switch to extinguish the arc.
