A second terminal is arranged on the first output electrode, a first terminal is installed on the first output electrode through an insulating plate, a fourth terminal is installed on the second output electrode through an insulating plate, and a second terminal is arranged on the left side of the first terminal. An input electrode, the right side of the fourth terminal is provided with a second input electrode; the center of the bracket is provided with a rotating shaft, one end of the rotating shaft is connected to a rotating disc, and a number of springs are fixedly connected above the rotating disc, and the ends of the springs Install the first rotating electrode and the second rotating electrode. The invention has the characteristics of high efficiency, low loss, large capacity, small volume and high stable performance.

Description

technical field [0001] The invention belongs to the technical field of a rectifying electroplating power reversing device, in particular to a rotary automatic reversing switch. Background technique [0002] The existing commutation method, low power uses relay commutation, high power uses manual switch or thyristor electronic commutation, the power of relay commutation is not large, the maximum current is generally below 200 amperes and the relay is unstable It is prone to failure; it is troublesome to change the direction with manual switch blades. Each time the direction is changed, it needs to be changed manually. Every time the direction is changed, electric sparks will be generated, which is easy to burn the switch blades. Over time, it is prone to poor contact and automatic change cannot be realized. The commutation efficiency of silicon controlled rectifiers is not high, and electronic devices with high heat generation are relatively fragile and parallel connections a...

[0002] The existing commutation method, low power uses relay commutation, high power uses manual switch or thyristor electronic commutation, the power of relay commutation is not large, the maximum current is generally below 200 amperes and the relay is unstable It is prone to failure; it is troublesome to change the direction with manual switch blades. Each time the direction is changed, it needs to be changed manually. Every time the direction is changed, electric sparks will be generated, which is easy to burn the switch blades. Over time, it is prone to poor contact and automatic change cannot be realized. The commutation efficiency is not high with silicon controlled rectifiers, and the heat generation is large. The electronic devices are relatively fragile, and the parallel connection is more unreliable and stable.
