Jilin load switch and the combination of electrical load switch for three-phase AC power system 10KV50HZ or supporting the use of power distribution equipment and modular substation switchgear ring network is widely used in fields such as engineering and mining enterprises network construction and renovation of public buildings and high-rise facilities can be assigned to control and protect the role of ring network or terminal power plays as the technical performance of the product in accordance with IEC Publication 60265-1 / FDIS high voltage switches over the first part of the rated voltage 1KV high voltage 52KV high voltage AC load switch IEC60420 below load switch - fuse combinations GB16926 AC high voltage load switch - fuse combinations GB3804-63KV AC high voltage load switch requirements. Back in the seventies load switch, sulfur hexafluoride switches and vacuum switches compete in the Cape appeared in a violent faction big debate in the international market. Sulfur hexafluoride faction proposed vacuum switch will have a strong X-ray breaking current process, seriously endangering the health of the operator, and should be a total ban on use. And sulfur hexafluoride gas has excellent arc performance and insulation performance, no - kind of media or mixed media to replace it. Vacuum faction believes sulfur hexafluoride gas by breaking current of Arc burned, immediately break down into toxic gas, sulfur hexafluoride switch box all the time from leaking into the atmosphere in trace amounts, the total leakage Dalian is very impressive load switch, especially when sulfur hexafluoride switch exploded undoubtedly more serious. If widely used sulfur hexafluoride gas as the media Harbin interrupter switch load switch, atmospheric pollution is out of control. Debate on the vacuum pressure to send very large, the school conducted a number of breaking current measurement, fortunately the X-ray measurement of radiation is significantly lower than the number of measurement standards and concluded that for the operator harmless. This great controversy at the time finally told a paragraph. Dalian 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.
