Abstract

A positioning tool for construction of a 10KV transformer test bench aims at solving the positioning problem of installation of the 10KV transformer test bench and comprises a connection arm, a measurement arm, a supporting arm, a sighting device and a fixing rod. The measurement arm comprises two parts which are bilaterally symmetrical and are hinged to two ends of the connection arm respectively. The supporting arm and the measurement arm are assembled together, and the supporting arm and the connection arm are assembled together. The sighting device is bilaterally symmetrical and is movably connected with the connection arm through a hinge. The fixing rod and the connection arm are assembled together. The positioning tool ensures positioning precision of the transformer test bench, avoids shortcomings of complicated operation, long preparation time, large device size, inconvenient carrying, high maintenance cost and the like caused by using a theodolites or a global positioning system (GPS), improves working efficiency, and reduces device acquisition expenses.

Description

technical field [0001] The invention relates to a positioning tool for a transformer stand, in particular to a positioning tool specially used for the construction of a 10KV transformer stand, and belongs to the technical field of power distribution or transformation. Background technique [0002] In the process of transmission line construction, the installation of distribution transformer bench is a key construction project that affects the operation of transmission lines. Not only the technical indicators of its basic electrical components must meet the requirements of the specifications, but also the on-site construction must be carried out in strict accordance with the design drawings. At present, during the construction of the 10kV transformer bench, the position of the transformer bench pole is determined using theodolite or GPS positioning system, which has defects such as complicated operation, long preparation time, large equipment volume, inconvenient carrying and ...
