Precautions For Installation And Maintenance Of Low Voltage Pole Mounted Sf6 Circuit Breakers

Pay attention to installation and maintenance. The allowable storage period for sf6 circuit breaker operating mechanism vacuum interrupters is 15-20 years. Therefore, spare parts should not be excessive, and the storage and operating environment should be free of chemically corrosive gases. When adjusting the contact opening distance, the compression of the bellows should be controlled to prevent plastic deformation. The rebound of the sf6 circuit breaker spring mechanism trip buffer should not be too large, as this will affect the life of the bellows.
