Isolation switch on the master terminal, ensure the formation of a significant portion of the fracture and live isolated from the line and equipment maintenance, when the switch is not due to isolation interrupter devices and low breaking capacity, so the operation Cangzhou isolation switch disconnectors, must comply Switching Hengshui disconnector operation sequence, when gives power, the first bus side isolation switch closed, followed by closing the line-side disconnector, and finally close the circuit breaker, power is opposite to the above. If the misuse or close with load isolation switch occurs, you should calmly to another in the opposite direction to avoid misuse that may occur. Is this: It has been found wrong with load after closing, shall not be opened immediately; when found with load brake, the Ruoyi opened, may no longer fit (if a little pull disconnectors, there are sparks when found, can be combined immediately on). Disconnectors for running inspections should be carried out. In the manned substation should once per shift; unattended in the middle of the distribution, at least once a week. Baoding disconnectors, Huayi Electric Power (certified), isolating switch is 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.
