Description

Technical field [0001] The invention relates to an electric operating mechanism, in particular to an electric motor operating mechanism. Background technique [0002] The high-voltage isolating switch is the auxiliary equipment of the power grid, and the opening and closing of the isolating switch is generally realized by the motor operating mechanism. The motor operating mechanism of the existing isolation switch is mainly composed of relays, travel switches, control buttons, motor drive mechanisms, temperature and humidity controllers, mechanical auxiliary switches and other circuits. The motor operating mechanism is the drive and control mechanism for the opening and closing operations of the isolation switch. . The auxiliary switch is a part of the main switch and is configured in high-voltage or medium-voltage circuit breakers, isolating switches and other power equipment as the opening, closing, signal control and interlock protection of the secondary control circuit. It c...
