Product details

series of AC high voltage automatic reclosers

 This product AC high voltage outdoor intelligent vacuum switchgear rated frequency 50Hz, rated voltage 12KV three-phase. It can replace the circuit breaker column alone; usually with high pressure slicer use together to form an intelligent power system protection features, flexible application of the urban network in the end 10KV substation, power ring road junction or on radial grid power lines, which not only has ZW32-12 vacuum circuit breaker with all the features and benefits, but also according to different protection requirements, flexibly arranged traditional three-current protection and over-current or speed off the anti-time protection.

 Recloser reasonably selected according to the different power system protection requirements with the corresponding inverse - second curve, coincides interval reclosing operation parameters such as the number of gates, achieve multiple reclosing lockout and ultimately into the closing state functions to achieve automatic rapid elimination of transient fault, permanent fault isolation purposes segments.
