Description

An insulation device for transformer low-voltage lead copper bar

Technical Field

The utility model relates to the technical field of insulation devices for lead copper bars, in particular to an insulation device for low-voltage lead copper bars of transformers.

Background Art

The BC phase coils need to be connected up and down through the transformer low-voltage lead copper busbar. Here the leads are concentrated and the distance is short. When the design distance requirement is met, the design distance cannot meet the safe operation requirements when the transformer oil quality is polluted and deteriorated due to other factors, which can easily cause safety accidents. The transformer low-voltage lead copper busbar needs to be insulated. Therefore, the insulation device for the transformer low-voltage lead copper busbar is an important component. In the existing insulation device for the transformer low-voltage lead copper busbar, partitions are used to insulate the transformer low-voltage lead copper busbar. Since the partition is connected to the transformer housing, the transformer low-voltage lead copper busbar and the partition need to be connected in steps, and they cannot be disassembled and installed without being fixed, which affects the stability of the insulation of the transformer low-voltage lead copper busbar. Therefore, we propose an insulation device for the transformer low-voltage lead copper busbar to solve this problem.
