Research on Simulation Technology of Opening and Closing Process of GW4 Disconnector in Normal and Jam Fault State

This paper mainly selects the commonly used type of isolating switch-GW4 isolating switch, establishes its three-dimensional simulation model, simulates and analyzes the force of each component during the opening and closing actions, and simulates and analyzes the jamming fault on the motor current and output torque of the electric mechanism. And the influence of opening and closing action process. It provides an important reference basis for the installation, commissioning, overhaul and maintenance of the isolation switch, and reduces the defect rate of the isolation switch accident.
