Abstract

This invention relates to a cover for the primary bushing of a distribution transformer, mainly composed of a cover body and at least one fastener. The cover body has a side opening, which has a first side and a second side. The first side has at least one hole, and the second side has at least one hole. The fastener passes through the holes of the first side and the second side, so that the first side and the second side of the side opening can be closed. This facilitates operation on the clamp-type joint of the primary bushing of the transformer and reduces the risk of accidents caused by contact with foreign objects.
