Operating range of the general provisions of the isolation switch disconnectors allowable operating range pull-in voltage transformers and surge arresters 1. normal. 2. Pull together 220kV bus load. 3. pull together the transformer neutral is not grounded grid failure. 4. Pull together via a switch or bypass current disconnectors closed. 5. Jog outdoor vertical triple isolation switch, pull-in voltage in 220kV and above the excitation current does not exceed the load transformer and capacitor current does not exceed 2A 5A of load lines. 6.10kV outdoor triple isolation switch pull together no more than 15A of load current. 7.10kV isolation switch pull together does not exceed 70A balanced current loop. Outdoor isolation switch disconnectors Yantai, outdoor installation should be mounted horizontally, so that support porcelain vase with rain skirt can indeed play a role; indoor Qingdao isolating switch disconnectors, when mounted vertically, the static contact in above, with the sleeve can be tilted at an angle to the installation. Under normal circumstances, then the power static contact, moving contact connected to the load, but installed by the electrical cabinet disconnectors, when using the cable entry, the power in the moving contact side, this connection called "poured into the fire . " On both sides of the busbar disconnectors and cable should be firmly connected isolating switch, in case of copper, aluminum conductor contact, copper and aluminum transition joints should be used to prevent galvanic corrosion. Xuzhou isolation switch, isolation 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!
