The AC high voltage load break switch is used in indoor or outdoor medium voltage systems at rated frequency 50/60 Hz. The load break switch is generally composed of disconnect blade, arc extinguishing chamber and operating mechanism. The arc extinguishing chamber will be made of insulating material with merits of high dielectric performance, and arc-endurances.
Generally, two types of load break switches (LBS) have been developed namely air-blast and SF6.In air-blast type, the interrupter heads same as those of used for isolation purpose in air-blast circuit breakers are employed for making and breaking currents. In SF6 type LBS, the gas serves as insulating and arc quenching medium.
