Abstract

Compared with permanent magnetic operating device

electromagnetic operating device has the characteristics of powerful output and long stroke

which can be used for middle and high voltage grade. A new type of long stroke magnetic operating device for 126 kV single break vacuum circuit breaker is presented on the basis of the development of 126 kV vacuum arcing chamber. Ansys simulation software is performed to simulate the static characteristics and increase the closing position holding force by change the way of auxiliary permanent magnet arrangement and end cap package. With the increasing of closing position holding force

the opening speed significantly increases. The influence of the electric parameters such as capacitance and coil turns on the dynamic characteristics is analyzed and the optimization of parameters is implemented. The simulation result indicates that the electromagnetic operating device of 126 kV single break vacuum circuit breaker has good operating characteristic.
