There Are Mainly Six Types Of High-voltage Load Switches

① Solid gas production high-voltage load switch: It uses the energy of the arc itself to turn off the gas producing material in the arc chamber to produce gas and extinguish the arc. Its structure is relatively simple and suitable for products with 35 kV and below.
② Pressure type high voltage load switch: It uses the pressure of the piston during the opening and closing process to blow out the arc. Its structure is also relatively simple and suitable for products with 35 kV and below.
③ Compressed air type high-voltage load switch: using compressed air to blow out the arc, it can disconnect large currents, and its structure is relatively complex, suitable for products of 60 kV and above.
④ SF6 type high-voltage load switch: using SF6 gas to extinguish the arc, it has a large breaking current and good breaking capacitor current performance, but the structure is relatively complex and suitable for products with 35 kV and above.
⑤ Oil immersed high voltage load switch: using the energy of the arc itself to decompose and vaporize the oil around the arc and cool it to extinguish the arc. Its structure is relatively simple, but it is heavy and suitable for outdoor products with 35 kV and below.
⑥ Vacuum type high-voltage load switch: using vacuum medium to extinguish arcs, with long electrical life and relatively high price, suitable for products of 220 kV and below.
