specific Embodiment
[0056] The operating mechanism for electrical switches provided in this embodiment is mainly used in a full series of high-voltage open-type isolating switches to control the 10kV mobile high-voltage generator car accordingly. Specifically, such as figure 1 , figure 2 and image 3 As shown, the operating mechanism includes a motor, a rotating drive member, an output shaft 8 for outputting power to enable the electrical switch to open and close, a first travel switch 4 and a second travel switch 5 . Wherein, the motor is connected with the rotary drive as the power source of the operating mechanism to drive the rotation of the rotary drive; the output shaft 8 is fixedly provided with a transmission that cooperates with the rotary drive, through the transmission of the rotary drive and the transmission. , to drive the output shaft 8 to rotate for power output. In its rotation stroke, the output shaft 8 has an opening output state in which the electric switch is opened in pla...

The invention relates to an operating mechanism for an electric switch and an electric switch. The operating mechanism for the electric switch includes a power source, a rotary driving part and an output shaft, the rotating driving part is connected with the power source, and is matched with the output shaft; the operating mechanism for the electric switch also includes the first and second travel switches and the first , The second elastic limiter, when the output shaft is in the opening state, it will continue to rotate along the opening direction for a certain angle, and then it will be separated from the rotating drive member; The power of the rotary drive is separated; the first and second elastic limiters are respectively used to restrict the output shaft from continuing to rotate after the output shaft is separated from the power of the rotary drive, and to make the output shaft rotate. The above technical solution solves the technical problem in the prior art that the electric switch body is easily damaged due to the failure of the travel control switch of the electric switch.
Description
technical field [0001] The invention relates to the technical field of high-voltage switchgear, in particular to an operating mechanism for an electric switch and the electric switch. Background technique [0002] The isolating switch is the most widely used electrical appliance in high-voltage switching appliances. It plays an isolation role in the circuit and is an important switching device for the power system to realize switching and switching circuits. Conventional open isolating switch mechanism generally adopts worm gear reducer structure, and the output angle of the operating mechanism is completely realized by stroke control micro switch. If the micro switch fails, the power source driving the output shaft of the operating mechanism will not stop, and the operating mechanism will continue to run, which is very easy to cause damage to the isolating switch body. Contents of the invention [0003] The purpose of the present invention is to provide an operating mech...
