Product structure
\
/ type neutral point isolating switch is mainly composed of the left contact assembly of the insulator terminal block and the right contact assembly. It consists of an upright rod-type insulator of corresponding voltage level and a rod-type pillar insulator respectively fixed on a base, and their intersection angles form a shaped structure. The base is fixed on a base assembly at an angle to the horizontal plane. Its appearance and internal structure are shown in the figure.
The bearing seat is as shown in the figure. The two holes on the base with an intersection angle have inclined surfaces and corresponding spherical surfaces on the bearing to form an adjustable link. The bevel gear can move up and down along the bearing core axis to adjust the meshing condition of the two gears.
