Detailed Product Description: | Isolation switch is mainly used to require high-voltage power distribution equipment parts and live parts reliably isolated to ensure the safety of maintenance work. Chang Lu disconnector contacts all in the air, with obvious break point, no disconnector interrupter device, and therefore can not be used to cut off the load current or short circuit current, otherwise, under high pressure, a strong arc off point disconnectors, and difficult to self-extinguish, and may even cause arcing (relative or phase short circuit) Hebei isolating switches, disconnectors Tianjin burning equipment, endangering the safety of the Tibet Autonomous Region isolating switch, which is called "negative Hera disconnectors" of serious accidents. Isolating switch can also be used for some of the circuit switching operation to change the system runs. For example: In the double busbar circuit, can be run in isolation switch circuit switching from a bus to another bus. At the same time, can also be used to operate a number of small current circuits. 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. Tianjin isolation switch disconnectors _ _ Huayi electricity provided by Xian 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! |
