Embodiment Construction
[0019] An example of the present invention is figure 1 , 2 , 3, 4, and 5, it is a vertical three-phase non-excitation neutral point five-speed forward and reverse voltage regulating tap-changer, which has a drum-shaped insulator 3 and an arc extinguishing cover 6 outside the insulator, so that the switch can be The inner electrified body is isolated from the outside world to further reduce the effective outer diameter of the switch. An upper support 2 and a lower support 14 are arranged above and below the insulator, and an insulating shaft 4 is arranged between the upper and lower supports. The upper end of the insulating shaft is connected to the The transmission shaft 1 mounted in the upper support is connected, and the upper end of the transmission shaft is connected with the switch operating structure 5. There are six layers of static contacts and moving contacts along the upper and lower sides of the switch, and each two layers corresponds to a phase. , the six layers ...
