The system configuration requirements include touch screen (human-machine interface), PLC, adjustable AC power supply, adjustable DC power supply, isolation protection circuit, control circuit, operating mechanism tooling, etc.

The pole-mounted vacuum circuit breaker (PVB) running in test is an important test conducted before leaving the factory or after installation, with the aim of ensuring good mechanical characteristics of the switch through a series of no-load opening and closing operations, eliminating burrs that may be left during the processing, correcting the shape, and achieving the best fit between components under design conditions. Break-in testing is crucial for improving the reliability of switchgear and extending its service life.
