Abstract

The invention discloses an electrified fastening device for a bolt of a transformer device, which solves the problem that the power-cut processing must be carried out when the bolt of the traditional electrified device is loosened. The electrified fastening device for the bolt of the transformer device comprises an axial operating rod, a radial operating rod, a sleeve and a gun drill, wherein the axial operating rod comprises a sleeve plug which is fixedly arranged at the top part of a rotating insulation rod and is used for inserting the sleeve and a drill sleeve which is fixedly arranged at the bottom part of the rotating insulation rod and is used for inserting the gun drill, and the outer part of the rotating insulation rod is also sleeved with a first insulation sleeve; and the radial operating rod comprises a second insulation sleeve, an L-shaped sleeve inserting frame is fixedly arranged at the top part of the second insulation sleeve, and two ends of the L-shaped sleeve inserting frame can be sleeved with the sleeve. The electrified fastening device for the bolt of the transformer device, disclosed by the invention, has the advantages that the structure is simple, the operation is convenient, the electrified device can be maintained under the condition without cutting off the power of the electrified device, the maintenance procedure is simplified, the labor intensity is reduced, the working efficiency is increased, and the economic loss and the social impact due to the power failure are avoided as well.

Description

technical field [0001] The invention relates to the technical field of power transformation equipment, in particular to a live work maintenance device for repairing power transformation equipment, in particular to a live fastening device for bolts of power transformation equipment. Background technique [0002] The outdoor substation equipment of the substation is exposed to the natural environment for a long time, and bears the normal mechanical load and strong wind. The bolts of the primary conductive part are loosened by the wind swing vibration, which causes the conductive part to heat up and cause the substation equipment to burn out. At present, it is necessary to cut off the power for maintenance to eliminate such defects, which not only complicates the work procedure, but also brings economic losses to industrial and agricultural production and seriously affects economic construction. According to statistics, in all power outage maintenance projects, the power loss o...
