High-pressure gas-pressure switch structure pressure load switch mainly six kinds ① solid gas-pressure load switch breaking arc itself use energy to arc chamber gas production materials to produce gas blew out the arc of its structure is relatively simple to apply to 35 one thousand volts and below the high-pressure compressed air products ② load switch breaking during use compressed air piston blew out the arc of its structure is relatively simple to apply to the following products ③ 35 kV and high-voltage load switch use compressed air blowing out the arc carve off large current structure is more complex and more applicable to 60 kV high-voltage products ④SF6 load switch: the use of SF6 gas extinguishing its breaking current breaking capacitive current performance is good but the structure is more complex and is suitable for 35 kV These products ⑤ Oil-filled high-voltage load switch itself by arc energy to break down the oil around the arc to extinguish the arc gasification and cooling structure is relatively simple, but the weight of its large 35 kV and below apply to outdoor products ⑥ high-voltage vacuum load switch with vacuum medium and long life electric arcing higher relative price applicable to 220 kV and below the essential difference between the product load switches and circuit breakers is their breaking capacity of different load switch Tongchuan Which is better? Breaker breaking capacity can be done in the manufacturing process is very high but the load switch breaking capacity is limited. Load switch plus fuse protection is generally protected only quick break and overcurrent. Mainly by adding breaker with current transformer secondary equipment to protect. Load switch is mainly used in the opening and closing of distribution transformers and small capacity (<800KVA). Breaker is mainly used in the regular breaking load of motors and transformers as well as large-capacity substation in Weinan load switch Which is better? Load switch, the power provided by the Xi'an Huayi Huayi power plant. Xian Huayi power plant (www.xahy.com) strong, credible, in Xi'an high-voltage circuit breakers and other industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead Huayi power and you hand into the brilliant, for a better future!
