System and method for testing effectiveness of transformer winding deformation detection device

Abstract

The invention relates to a system and a method for testing effectiveness of a transformer winding deformation detection device, the system comprises a deformation generator, a winding deformation detection device clamping position connected with the deformation generator and a power source, a microprocessor unit is connected with the deformation generator through the power source, and the power source generates a power supply. The winding flowing through the load and the deformation generator forms a loop; and the deformation generator comprises silicon steel, windings are arranged at the two ends of the silicon steel, and a single-winding deformation generator and a multi-winding deformation generator are formed respectively. The microprocessor unit simulates various situations and compares the same winding value with original data and historical data, and if the winding deformation detection device tests that the relative change of the winding parameters of the system is not larger than + / -2%, the effectiveness of the winding deformation detection device meets the requirement.

Description

technical field [0001] The invention relates to the field of power instrument testing, in particular to an effectiveness testing system and method for a transformer winding deformation detection device. Background technique [0002] The safe operation and maintenance of the power system is the result of the joint action of various equipment. Power transformers are expensive but have a large role and involve a wide range of areas. Therefore, the research on ensuring their safe operation is of great significance. It can be seen from the statistical data on transformer accidents over the years that transformer windings are one of the most faulty components. Judging from the disassembly of the transformer, the transformer faults caused by the deformation of the winding account for the vast majority. In addition, from the analysis of the transformer accident location and defect situation in the national statistics, the coil and lead wire outlet are the most important part of the...
