FZW32-12 outdoor AC high voltage vacuum load-breaking switch is a new type of load switch designed manufactured via integrating the mature experience of domestic existing load switch production and foreign advanced technology.

This load switch consists of the isolating switch, arc extinguish chamber, operating mechanism and so on. It adopts the principle of vacuum arcing. With strong arcing ability, reliable performance long life, small volume, no explosion hazard and no pollution of the environment.

Corresponding vacuum load switch can be used for the transmission and distribution system of electric power, metallurgy, mining, chemical engineering and other departments for control equipment, especially suitable for frequent operation.

Automatically cut single phase earthing fault: when users tributary line cause single phase earthing fault, the boundary switch will open automatically, other distribution line users of the substation and feeding line will be without influence; isolation interphase short circuit fault automatically.

When the tributary line cause interphase short-circuit fault, boundary switch will open at once after out-wire protection tripping. After the substation reclose, fault line is isolated passively, other distribution users in feeding line resume power supply rapidly (equal to a transient fault).

Quick localization of fault: the tributary line fault cause boundary switch protection action, only the accident user cause power cut and by itself report the fault information, the power company could dispatch worker to live investigation; if the boundary switch match with communication module, it could transmit message to electricity management center.

Monitoring users load, boundary switch could configure wired or wireless communication enclosure to monitor data and transmit to electricity management center, make the achievement of real-time data monitoring of users load in long distance.

Function of network running, it could be used in network lines; function of measurement, monitor voltage, current, frequency and quantity of electricity of lines, and transmit to management center in long distance. Function of harmonic analyzing, to supply reliable basis for pollution administration of electricity net afterwards.
