Abstract

The invention relates to a gear adjusting tool of a dry type transformer and a using method of the tool, and belongs to the technical field of transformer operation and maintenance. According to the technical scheme, circular ring cylinders (11) are fixedly arranged on the left side and the right side of a connecting plate respectively, and bearings (3) are arranged in the circular ring cylinders.Sleeve adapters (4) are fixed in the bearings (3), T-shaped handles (5) are arranged at the rear ends of the sleeve adapters (4), and universal sleeves (6) are arranged at the front ends of the sleeve adapters (4). A baffle slide way frame (9) is vertically arranged at the lower end of the connecting plate, a clamping plate (72) is located in front of the baffle slide way frame (9), and a slidingbottom plate (71) penetrates through the baffle slide way frame (9). A spring fixing plate (73) is located behind the baffle slide way frame (9), and a spring (10) is arranged between the spring fixing plate (73) and the baffle slide way frame. The tool has the advantages that bolts, gaskets and gear adjusting connecting pieces can be effectively prevented from accidentally sliding off, the gearadjusting connecting pieces are more convenient to assemble and disassemble, and the working efficiency is improved.

Description

technical field [0001] The invention relates to a shifting tool for a dry-type transformer and a method for using the same, belonging to the technical field of transformer operation and maintenance. Background technique [0002] For dry-type transformers in operation, too high or too low voltage on the low-voltage side will have adverse effects on the load. At this time, it is necessary to manually adjust the gear of the transformer to ensure that the voltage on the low-voltage side remains within the normal range, and the maintenance test of the dry-type transformer is also necessary. Involves frequent shift operations. [0003] The traditional dry-type transformer shifting is to first use a wrench to remove the bolts on both sides of the shifting connecting piece, then move the connecting piece to the middle of the target tap, insert and tighten the bolts on both sides to achieve the purpose of shifting. When dismantling / installing bolts, it is easy to trip and drop the b...
