【Abstract】 In order to simplify the machine structure and improve the working reliability of the operating mechanism, taking the 40.5 kV vacuum circuit breaker as the research object, a new type of brushless excitation motor operating mechanism is designed according to its dynamic mechanical characteristics. The load characteristics of the 40.5 kV vacuum circuit breaker are analyzed, and the three-dimensional finite element analysis of the new structure motor is carried out by using the load reaction curve of the circuit breaker. On this basis, the hardware platform of the control system of the operating mechanism is built, the prototype of the 40.5 kV vacuum circuit breaker and the prototype of the new brushless excitation motor are made, and the operation of the closing test verification is carried out. The simulation and test results meet the closing technical requirements of 40.5 kV high voltage vacuum circuit breaker. The feasibility of the new brushless excitation motor operating mechanism is verified.更多还原
