High voltage load switch is a function of electrical high voltage switches between high-voltage circuit breakers and high-voltage isolation switch between the series often used in conjunction with a high-voltage fuses used to control power transformer voltage load interrupter switch has a simple device because they can pass off some The load current and overload current, but it can not disconnect the short circuit current so it is generally used in tandem with the aid of high-voltage fuse fuse to it breaking load capacity of a short-circuit protection with load switch is off self-extinguishing feature very small and very limited two disconnectors are generally not take the load of the structure is not breaking interrupter cover can also breaking load and load switch disconnectors only relatively simpler three different load switch and isolating switch can form a significant structural break Most non-prescription breaker isolation circuit breaker with a small number of isolated features four isolation switch does not have the protection function to protect the load switch plus fuse protection is generally only 5 quick break and overcurrent circuit breaker breaking capacity in the manufacturing process can be done The high increase was mainly rely on the current transformer with a secondary device may have short-circuit protection Overload protection leakage protection and other functions, Baoding, Cangzhou load switch load switch _ Huayi Electric Power (certified) _ load switch from Xi'an Huayi power plant available. 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.
