Description

technical field [0001] The invention relates to a handcart type switch electric advancing and retreating device. Background technique [0002] The conventional operation method for handcarts such as circuit breakers, isolating switches, and voltage transformers in 10kV mid-mounted switch cabinets is to insert the operating handle into the operating hole of the screw rod, shake the handle clockwise to push the handcart from the test position to the working position, and then exit from the working position. To the test position, you need to shake the handle counterclockwise. [0003] When the handcart of the circuit breaker reaches the working position, the chassis auxiliary switch contact is closed, and the switch cabinet door panel status indicator shows that the handcart is in the working position; when the handcart exits to the test position, the chassis auxiliary switch contact is closed, and the switch cabinet door panel status The indicator light shows that the handcar...
