Problems solved by technology

[0002] At present, most of the secondary busbar bridges of 66kV main transformers are flat copper bar busbars. The operation and maintenance personnel need to climb up to the main transformer to hang the flat mouth grounding wires when performing the operation of hanging the grounding wires, and fix them by rotating. The second is that the installation work is relatively dangerous. In view of this, after in-depth research on the above problems, this case arose

Abstract

The invention discloses a 66kV main transformer secondary bus bridge ground wire suspension device which comprises an inner pipe and an outer sleeve, the outer sleeve is arranged on the outer side ofthe inner pipe in a sleeving mode, the outer sleeve is connected to the inner pipe through an overturning structure, and a clamping structure is installed in the inner pipe. The overturning structurecomprises a driving rod, a concave driving bearing block, a driving rotating shaft, a driving shaft, a Y-shaped transmission rod and a transmission shaft; the invention relates to the technical fieldof substation electrical equipment, and can facilitate an operator to complete the installation of a grounding wire on the ground by using an existing grounding operation rod and the grounding wire. Meanwhile, the device can ensure electrical insulation meeting requirements during operation, is applied to a 66kV transformer substation, is convenient to operate and reliable in contact, saves operation time, and reduces operation risks of operators.

Description

technical field [0001] The invention relates to the technical field of substation electrical equipment, in particular to a ground wire suspension device for a secondary bus bridge of a 66kV main transformer. Background technique [0002] At present, the secondary busbar bridges of 66kV main transformers are mostly flat copper bar busbars. When operating and maintaining the ground wire, the operation and maintenance personnel need to climb up to the main transformer to hang the flat mouth ground wire, and fix it by rotating. First, the contact is not firm. The second is that the installation work is relatively dangerous. In view of this, this case arose after in-depth research on the above-mentioned problems. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention provides the background technology close to the cable or cable processing, and solves the problems of the existing background technology. [0004] In order to achieve...
