Research on Simulation Technology of Opening and Closing Process of High Voltage Isolating Switch in Normal and Fault State

The high-voltage isolating switch is an important switching device in the electrical system of power plants and substations. This article takes the GW23B-252 isolating switch as an example, and conducts dynamic simulation on it. This paper Obtains the relationship between the output shaft torque and rotation angle of the operating mechanism with time by simulating the closing and opening process of the main knife under normal operating conditions. Which provides a reference basis for the installation, commissioning, overhaul and maintenance of the isolation switch, and provides guidance for fault diagnosis and product maintenance.
