In order to reach object above, this utility model be the technical scheme is that this transformer test bus bar isolating device, it is characterized in that: include the fixing plate of top insulation fixing plate, upper end connecting rod, lower end connecting rod, swivel nut and bottom insulation, in the middle part of the back side of top insulation fixing plate and the fixing plate of bottom insulation, be equipped with triangular splint；The triangular splint of top insulation fixing plate is rotationally connected by the top of plastics bearing pin Yu upper end connecting rod；The triangular splint of the fixing plate of bottom insulation is rotationally connected by the bottom of corresponding plastics bearing pin with lower end connecting rod；The screw thread of the female thread first half of described swivel nut is contrary with the hand of spiral of lower half, corresponding thereto, the bottom of upper end connecting rod and the top of lower end connecting rod are provided with the external screw thread that the female thread with swivel nut matches, the bottom of upper end connecting rod screws in the top in swivel nut, and the top of lower end connecting rod screws in the bottom in swivel nut.
This utility model is implemented also by following measure: described top insulation fixing plate and the fixing plate of bottom insulation are rectangular slab, four corners of top insulation fixing plate are equipped with the bolt of connection corresponding to bus-bar compression joint head, and four corners of the fixing plate of bottom insulation are equipped with the bolt of connection corresponding to transformator upper sleeve portion.
Described top insulation fixing plate, bottom insulation fix plate, plastics bearing pin makes by high-strength engineering plastic.
The beneficial effects of the utility model are in that: this transformer test bus bar isolating device, it is not only simple in structure, with low cost, easy to carry, and due to when carrying out transformer high-voltage experiment work, particularly it is applied in 35kV and above transformator power failure experiment work, can by the casing off of the crimp head of bus bar removed with transformator upper end, so operation safety, time saving and energy saving, labor efficiency can be promoted, and ensure that the reliable fixing of bus bar, ensure that itself and transformator upper sleeve portion keep enough safe distances, the speed installed and resume work can be improved.
