Abstract

The invention discloses an operation mechanism of a motor. The operation mechanism comprises an auxiliary electronic switch, a controller, an angle detecting unit, a voltage detecting unit, a current detecting unit, a serial communication interface, a display unit, a data storage unit and a control button. The angle detecting unit is used for detecting the rotating angle of an output shaft of a motor speed reducer. The auxiliary electronic switch comprises a signal processing circuit and a power amplifying circuit, and the signal processing circuit comprises a TTL open collector six-normal-phase high-voltage driver, a TTL open collector six-reverse-phase high-voltage driver and multiple power amplifiers. The TTL open collector six-reverse-phase high-voltage driver is connected with the TTL open collector six-normal-phase high-voltage driver, and the power amplifiers are connected with the TTL open collector six-reverse-phase high-voltage driver. The TTL open collector six-normal-phase high-voltage driver is connected with the motor control end of the controller. The power amplifying circuit comprises multiple sets of solid relays. The operation mechanism is simple in circuit, reasonable in design, convenient to wire, good in using effect and capable of solving various problems existing in an existing operation mechanism of the motor.

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 an auxiliary equipment for the power grid, and the opening and closing of the isolating switch is generally realized by a motor operating mechanism. The motor operating mechanism of the existing isolating switch is mainly composed of relays, travel switches, control buttons, motor driving mechanism, temperature and humidity controller, mechanical auxiliary switch and other circuits. The motor operating mechanism is the driving and controlling mechanism for the opening and closing operation of the isolating switch. . The auxiliary switch is a part of the main switch, which is configured in high-voltage or medium-voltage circuit breakers, isolating switches and other electrical equipment as the opening, closing, signal control and interlocking protection functions of the seco...
