Product Description
The product is specially designed for operating ZW32-12 outdoor high-voltage
vacuum breaker, and other outdoor or indoor vacuum circuit breakers which have
the 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-D for electrical operation system, has the functions of
energy storage, switch on and off, over current protection who can inrush
current and quick break protection.
Service conditions:
1, surrounding
air temperature: from -20 ℃ to 45 ℃.
2, elevation: ≤ 2000 m; Wind speed: ≤35
m/s.
3, Daily relative humidity: ≤95%, Monthly relative humidity: ≤ 90%
4,
Places: no regular violent vibration.
Technical parameters:
Energy
storage uses one-way permanent magnet DC motor , its technical data to see table

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 HV vacuum breaker equipped with the mechanism are as
follows:
(1)Switch closing time (electric operation): at the highest
operating voltage:≤30 ms, at the lowest operating voltage≤60 ms.
(2) Switch
opening time (electric operation): at the highest operating voltage≤20 ms, at
the lowest operating voltage≤40 ms.
(3) Interval of no current in reclosing
≤30 ms.
4,When through continuous AC current of 220V, the current of
auxiliary switch contact equipped with the mechanism is 10A , and 5A when
through DC current of 220V.
5,Overtravel-limit switch CSK-22Magnetic blow
switch which has two normally open contact and two normally close contact.
Current of the contact through continuous AC current 220V is 10 A and 3A though
DC 220.
