Embodiment Construction

[0009] As shown in the figure, the inner cavity 2 of the insulating housing 1 of the indoor integrated disconnector of the present invention is cylindrical, the main shaft 3 is set It consists of upper arm 5 and lower arm 6, and upper contact 7, lower contact 8 and ground contact 9 are respectively embedded in the upper part, lower part and one side part of the inner cavity of the housing. The upper conductor 11 connected between the upper contact 7 and the wire-in terminal 10 and the lower conductor 13 connected between the lower contact 8 and the wire-out terminal 12 are covered in an insulating material. An installation plane 14 is provided at the incoming line end, which is used to cooperate with the power transmission busbar. The three-phase incoming line ends 10 are arranged side by side in the axial direction, and at the same time, they are staggered at a certain angle in the radial direction. The outlet end 12 is a cylindrical contact finger 15 for connecting with plug...
