Embodiment Construction

[0100] 8.1 Overview

[0101] Transformers are the most important and valuable equipment in power transmission, transformation, and distribution systems. The safe operation of transformers is the top priority for leaders at all levels of the power supply system, especially the safe operation of ultra-high voltage large-capacity transformers is the top priority. . Since the accident rate of transformers damaged by the impact of short-circuit current remains high, the Ministry of Safety and Transport of the State Power Corporation requires all provincial and municipal power companies (bureaus) to carry out tracking and detection of the dynamic and stable state of large and medium-sized power transformers, and try their best to reduce short-circuit accidents of transformers. . The "CD9882 Transformer Dynamic Stability Parameter Tester" developed by our factory under the guidance of Guodian company-level scientific and technological experts came into being, and it is a powerful to...

Abstract

The present invention relates to a transformer dynamic stability condition parameter testing apparatus and its diagnosis software. Said product is composed of testing apparatus and diagnosis software, and said invention is characterized by that it adopts a low-voltage reactance method to diagnose the winding deformation of power transformer and changed condition of iron-core looseness in the place so as to create a set of complete high-effective detection and diagnosis method, its detection accuracy is high, can be up to 0.2 grade.

Description

1 technical field [0001] This project belongs to the power system informatization and automation, digital state detection instrument and power equipment state maintenance software in the field of optomechanical integration technology. [0002] In 2003, it passed the appraisal of scientific and technological achievements organized by Gansu Provincial Department of Science and Technology. [0003] In 2003, it was awarded the project certificate of technology innovation fund approved by the Ministry of Science and Technology and the Ministry of Finance. [0004] The State Grid Corporation of China is organizing the drafting of the low-voltage short-circuit impedance method standard, and the detection and diagnosis method developed in this project will be included in the industry standard. [0005] This project consists of two parts: testing equipment and diagnostic software. The detection instrument is responsible for the basic test of the transformer, which is used to accurate...
