◎Overview
This product can operate ZN28 indoor high-voltage vacuum circuit breakers on various 10KV fixed cabinets and other types of high-voltage circuit breakers with equivalent closing power. It has overcurrent and undervoltage tripping protection functions, and its mechanical life is 2000 times. Since the width of this structure is smaller than that of CT19A type, the width is only 300mm, which not only increases the overall stability of the mechanism, but also is more suitable for oil-free transformation on old cabinets. (The output of this mechanism is converted to 50°~55°)
◎Main technical parameters
Specifications Weight kg Volume Height × Width × Depth mm Motor Input Power (W) Closing Spring (mm) Matching Equipped with vacuum circuit breaker breaking current (KA) CT19B-Ⅰ 38550×330×180 110φ720 CT19B-Ⅱ 38550×330×180 110φ8 31.5 CT19B-Ⅲ 38550×330×180 150φ8+φ440
1. The energy storage motor adopts a single-phase permanent magnet DC motor. If the user needs to use an AC current power supply, the full-wave rectifier current is increased, and the (bridge stack) supplies the energy storage motor. The motor can work.
2. The closing and opening electromagnet adopts a solenoid type electromagnet.
3. The working rotation angle of the output shaft of the mechanism is 50-55 degrees.
