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:
rated voltage(V) | ~220 | ~110 | -220 | -110 | -48 | -24 |
rated current(A) | 1.8 | 4 | 1.5 | 2.2 | 5 | 11.5 |
rated capacity(W) | 400 | 440 | 330 | 250 | 240 | 276 |
coil resistance at 20℃(Ω) | 50 | 9 | 150 | 50 | 9 | 2.1 |
Voltage range | Switch opening:65%~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.
