    Automatic Reclosing Switch

    Applicable place:(Suitable forplaces with high voltage level)

    1.Overhead lines.

    2.Industrial.

    3.Mining enterprises.

    4.Power stations.

    5.Substations.

    This is a new type of on poleswitchgearin vacuum circuit breaker series products in China.

    PRODUCT FEATURES:

    1.Unilateral voltage increase time delay

    The delay time is continuously adjustable. The VCBr will not close When the voltage increases at both sides, however it will automatically open when the voltage is loss.

    2.Over current protection

    Inverse time over current protection, and the over current value can be randomly set through the keyboard.

    3.Quick-breaking protection

    Inverse time quick-breaking protection, and the quick-breaking value can be randomly set through the keyboard.

    4.Small current earthing protection

    Time-limited small current earthing protection, and the protective current value can be randomly set through the keyboard.

    5.Reclosing function

    Multiple-reclosing function, the reclosing time and the reclosing interval can be randomly set through the keyboard.

    6.Inverse time function

    20 fast & slow inverse time A-T curves will be provided, to realize the automatic cooperation between the higher and the lower.

    7.Closing lock

    If the VCB closes on the fault point, the controller will automatically open it and realize closing lock.

    8.Sequency cooperation

    If the fault occurs on its front line, the upstream recloser will prevent the downstream recloser from acting, however, it will automatically isolate the fault zone without breaking if the fault occurs on the line of the downstream recloser.

    9.Four remote function

    Standard RS-485 communication Interface can work

    10.Memory

    The data will be automatically stored in the memory (Non volatile memory) for not less than 20 years

    11.Three-step protection

    Power on password protection, only the authorized person can change the settings. The instal lation position of the meter is preserved in the box of the controller.

    12.Local remote control

    The remote control distance is 50m.
