Product descroption
ZW32 is an automatic current recloser with a rated voltage of 12kV, AC three-phase frequency of 50Hz. With installation of an intelligent controller, switch can realize power transmission and distribution automatically. Remote control and adjsutment are available by controller. This recloser has motorized spring type & magnetic actuator (with control box) type.
In electric power distribution, an auto-recloser is a circuit breaker equipped with a mechanism that can automatically close the breaker after it has been opened due to a fault. Generally, a transient fault will open the breaker for a time until a technician could manually close the circuit breaker or replace the blown fuse,yet autoreclosers will attempt to open and close for several times to clear the transient fault. Because of these advantages, autorclosers are frequently used as protection units for power distribution circuits in Vacuum interrupter,however,as the most important part determine its performmance in a certain degree.
