    Abstract: The generator outlet switch is the key core equipment of the power generation output link, and a complete set of generator outlet switch devices for small and medium-sized hydropower stations has been developed to protect the safety of generators and power equipment.The design process of high-voltage switchgear and circuit breaker is given, and the mechanical strength and switching characteristics of the circuit breaker design scheme are verified by simulation. The prototype production and type test verification show that the product has the remarkable characteristics of compact structure, efficient operation, easy installation, reliable operation and stable performance, and has been stably operated in some national key projects.
    Key words: fixed cabinet; generator outlet circuit breaker; thermal stable current; dynamic stable current
