Problems solved by technology

[0003] At present, the following are still widely used in the power system: 1. Circuit breakers with relatively complex operating mechanisms; 2. The operation functions of phase selection closing and synchronous breaking cannot be realized; 3. The action time cannot be guaranteed to be short enough; 4. Needs Separately equipped with a microcomputer protection device to monitor and control its operating conditions; 5. The degree of integration is not high; 6. The function is single; 7. It is not possible to check whether the mechanical characteristics of the circuit breaker are unfavorable to safe operation during operation. Changes, whether the heating condition between the moving and static contacts is kept within the allowable temperature rise range, whether a short-circuit fault occurs in the power supply feeder circuit, and whether the protection action can be taken in the shortest time, so as to quickly cut off the fault current and protect the stable operation of the power grid system , and at the same time, can the above information be passed on to the management personnel for processing and timely mastery, etc.
