Embodiment Construction

[0007] The embodiment is described in detail in conjunction with the accompanying drawings. The embodiment of the present invention is an emergency conversion tool for distribution transformer maintenance grounding wires, which includes connecting ground wires 4 and bolts 3. A butterfly screw 2 is mounted on the U-shaped clamping plate 1. One side of the U-shaped clamping plate is provided with a fixed ring 5, and the two ends of the connecting ground wire are provided with a connecting snap ring 7, and the bolts are fixedly connected to the connecting snap ring and the fixing ring, and the length of the connecting ground wire can be adjusted according to different use environments. Replacement; the position corresponding to the butterfly screw on the U-shaped clamp described in this embodiment is provided with a groove 6, which is convenient for the U-shaped clamp to cooperate with the butterfly screw to fix the grounding steel brazing or grounding flat iron.

Abstract

The invention discloses an emergency conversion tool for a distribution transformer overhauling ground wire. The emergency conversion tool for the distribution transformer overhauling ground wire is reasonable in structure and good in use effect. According to the technical scheme, the emergency conversion tool for the distribution transformer overhauling ground wire comprises a connecting round wire and bolts, a butterfly-shaped screw rod is assembled on a U-shaped clamp plate, a fixing ring is arranged at one side of the U-shaped clamp plate, a connecting clamp ring is arranged at each of two ends of the connecting ground wire, and the connecting clamp ring is firmly connected with the fixing ring through the bolts. A groove is formed in the position of the U-shaped clamp plate corresponding to the butterfly-shaped screw rod. The emergency conversion tool for the distribution transformer overhauling ground wire can be operated by one person; the emergency conversion tool for the distribution transformer overhauling ground wire is easy and quick to use, provides security assurance for overhauling a distribution transformer, and avoids construction hazards.

Description

Technical field: [0001] The invention relates to an electric power construction tool, in particular to an emergency conversion tool for a distribution transformer maintenance grounding wire. Background technique: [0002] The grounding wire is an important safety tool for distribution transformers in daily operation or maintenance. It is mainly used as a safety measure after a power outage of the distribution transformer. The current is introduced into the earth, so as to achieve the purpose of protecting personal safety. It is also possible to discharge the equipment during the distribution transformer test. At present, distribution transformers are mostly installed on outdoor structures, and it is often impossible to insert the grounding electrode when the ground at the bottom of the structure is completely hardened, which brings great safety hazards to the staff who overhaul the distribution transformers. Invention content: [0003] The purpose of the inventio...
