Split type change-over switch of on-load tap-changer

The split type change-over switch comprises a switch assembly and a frame assembly, the switch assembly is arranged in a box body, and the switch assembly is connected with a transformer through a wire inlet sleeve and connected with a transition resistor through a wire outlet sleeve. The switch assembly and the transformer are insulated and isolated through the wire inlet sleeve, the transition resistor is arranged outside the box body and used for limiting loop current of the switch assembly, and a frame assembly is arranged on the lower portion of the switch assembly and fixedly connected with the box body. By adopting the arrangement of the quick mechanical switches, the fault rate can be reduced, the service life of the equipment can be prolonged, the maintenance workload can be reduced, the action process of the whole change-over switch is monitored by arranging the current sensor at the wire outlet of each switch, the whole-process monitoring of the equipment is realized, and the safety and reliability
