SecoVac 3.3kV-27kV Embedded Pole Vacuum Circuit Breaker
The high quality of the embedded pole is achieved by using the latest APG (Auto Pressure
Gelation) technology and advanced vacuum mixing and degassing technology. The
Vogel clamping machine is an essential piece of equipment to ensure the mechanical
and insulating strength of the embedded pole of 3.3kV-27kV series MV embedded pole
vacuum circuit breaker.
As well as the processing facilities, the testing facilities are also very important to the
quality control of the breaker. In the manufacturing process of SecoVac, from incoming
^ ;
and tested.
Every embedded pole goes through the following inspection and testing before it is
allowed into the breaker assembly line:
ő X-ray inspection
ő Power frequency withstand voltage test
ő Partial discharge measurement
ő Thermal cycling test
Before delivery, the following tests and inspections will be done for 3.3kV-27kV
embedded pole vacuum circuit breakers in factory by means of advanced testing
equipment:
ő Dynamic characteristics measurement (Closing/opening speed, contact bounce, wipe
etc.)
ő Power frequency withstand voltage testing
ő Inspection of interlocking system between breaker and withdrawable unit
ő Secondary wiring inspection
ő Circuit resistance measurement
The state-of-the-art processing and advanced quality control
