     Product Description

    Model:CT37-S
    Product Name: CT37-S spring operating mechanism
    Product Description:

    The product is specially designed for operating ZW32-12 outdoor HV vacuum breaker and other outdoor or indoor vacuum breakers which have equal switching work.It can meet with the requirements of GB1984 high-voltage AC breaker and the technical conditions of the product. And all the indexes have reached and exceeded the relevant standards of the high-voltage AC breaker in IEC56. CT37-S for manual operation system, has the functions of manual energy storage, manual on and off and over current protection who can inrush current and quick break protection .
    Service conditions:
    1, Air temperature: from -25 ℃ to 45 ℃.
    2, Elevation: ≤ 2000 m; Wind speed: ≤35 m/s.
    3, Daily relative humidity: ≤95%,Monthly relative humidity: ≤ 90%
    4, Places: that no regular violent vibration.
    Technical parameters:
    1, It uses a special energy-stored handle of the circuit breaker to finish manual energy-stored operation with a one way structure. And the operating force is less than 100 N.m.
    2, Open and close the switch through screw tubular electromagnets, the technical parameters see table 1:

    Switch opening:65%~120% of rated voltage;
    Below 30% of rated operational voltage, cannot open the switch;
    Switch closing: 85%~120% of rated voltage

    Technical data of overcurrent tripper, to see table 2:

    rated current 5A

    coil DC resistance at 20℃2.5Ω

    Current range

    90%—110% of rated current, can trip; below 90% of rated current, mustn’t trip


    1, Output flip angle of the mechanism: from 38 to 40
    2, Net weight of the mechanism: 8.6kg
    3, Action times of ZW32-12 outdoor high voltage vacuum circuit breaker equipped with the mechanism are as follows:
    (1)Switch closing time (electric operation): not less than 30 ms at the highest operating voltage; not more than 60 ms at the lowest operating voltage.
    (2) Switch opening time (electric operation): ≤20 ms , ≤40 ms at the lowest operating voltage.
    (3) Interval of primary current: ≤30 ms.
