Problems solved by technology

[0003] The use of electric power is inseparable from the circuit breaker. The circuit breaker refers to the device that can close, carry and break the current under normal circuit conditions and can close, carry and break the current under abnormal circuit conditions within a specified time. Switchgear and circuit breakers are divided into vacuum circuit breakers, high-voltage circuit breakers and low-voltage circuit breakers according to their scope of use. The insulating medium in the back-arc contact gap is named after high vacuum. It has the advantages of small size, light weight, suitable for frequent operation, and no maintenance for arc extinguishing. It is widely used in distribution networks. Due to the high-voltage vacuum circuit breaker There are many parts, so the assembly efficiency is low, and the assembly quality cannot be guaranteed, which is not conducive to the interests of the enterprise itself. Therefore, we propose a high-voltage vacuum circuit breaker assembly process
