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 product load switch and the combination of electrical isolation from the main switch box combiner limiting fuse isolating switch on the vacuum switch grounding switch spring operating mechanism, etc. composed of Qingdao, Qingdao load switch load switch _ Huayi Electric Power (certified) _ load switch provided by Xian Huayi power plant. Xian Huayi power plant (www.xahy.com) is a leader in Xi'an, high voltage circuit breakers, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Huayi power in leadership with the staff warmly welcome all inquiries negotiations to create electricity Huayi a better future.
