Problems solved by technology

In the prior art, maintenance personnel measure the discharge gap between the neutral point of the transformer and the lightning arrester by using a box ruler to re-measure the discharge gap of each piece of equipment. It is difficult to find the exact level of the measurement, the measurement data has large errors, and the reliability is low; 2. It is extremely inconvenient to carry a variety of tools when climbing up and down the ladder; 3. The work is not only dangerous but also time-consuming and laborious.

Abstract

The invention discloses a tool for adjusting a discharging gap between a neutral point of a main transformer and a lightning arrester. The tool comprises a discharging gap adjusting rod, a chute plate, an elevation mechanism, a support, a workbench and a ladder, wherein the discharging gap adjusting rod is placed in a cross groove in the upper end surface of the chute plate, the lower end of the chute plate is hinged to the support provided with the elevation mechanism, the workbench is fixed at the upper end of the ladder, and the elevation mechanism is placed on the workbench. The tool is connected to a pedestal of the lightning arrester fixedly, safely and reliably, mounting and dismounting are rapid, use is convenient, the discharging gap adjusting procedure is simplified, construction safety is ensured, the labor intensity is reduced, and the maintenance quality is improved.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to a tool for adjusting a discharge gap between a neutral point of a main transformer and a lightning arrester. Background technique [0002] In the process of transformer maintenance, it is often necessary to adjust the discharge gap between the neutral point of the transformer and the arrester. During the maintenance operation, first measure the length of the discharge gap. If the length of the discharge gap does not meet the requirements of the technical specification, the original discharge electrode rod must be extended to make the length of the discharge gap meet the requirements of the technical specification to ensure the safe operation of the equipment. In the prior art, maintenance personnel measure the discharge gap between the neutral point of the transformer and the lightning arrester by using a box ruler to re-measure the discharge gap of each piece of equipment. ...
