Transformer partial discharge positioning simulation device

Abstract

The invention discloses a transformer partial discharge positioning simulation device and relates to the transformer discharge detection technology field. During existing transformer partial discharge positioning, an ultrasonic method and a ultrahigh frequency method are adopted so that accuracy and validation have defects. Aiming at the above technical problem, a transformer box body, a voltage regulator, a wiring board, a partial discharge source and a mobile positioning platform are adopted. The partial discharge source is arranged on the mobile positioning platform, and the partial discharge source and the mobile positioning platform are arranged in the transformer box body. The mobile positioning platform can move in the box body and the partial discharge source can be placed in a three-dimensional space. In the invention, a type of the partial discharge source is replaced and the partial discharge source is accurately placed in the transformer box body so that various partial discharge types in the transformer can be simulated, and a research or detection object is provided for researching a partial discharge signal propagation characteristic and inspecting effectiveness of a partial discharge positioning apparatus. By using the device, transformer partial discharge positioning detection technology training can be visually developed. And the device possesses characteristics that positioning precision is high; cost is low; and usage is convenient.

Description

technical field [0001] The invention relates to the technical field of transformer discharge detection, in particular to a transformer partial discharge location simulation device. Background technique [0002] Power transformers are one of the most important equipment in power plants and substations, and their safety has an important impact on power grids and social stability. Due to the reasons of design and manufacture, process materials, operation and maintenance, and operating environment, internal insulation faults of transformers occur from time to time. In the initial stage of the internal insulation fault of the transformer, partial discharge is generally generated. Although the type of partial discharge can be preliminarily judged through partial discharge detection combined with oil chromatography analysis, electrical test and other technical means, the location of partial discharge cannot be accurately known, which is not conducive to the decision-making of opera...

Problems solved by technology

[0003] The invention provides a transformer partial discharge locating simulation device, which is used to solve the problem that the existing transformer partial discharge locating method adopts the ultrasonic method and the UHF method, and the UHF signal is blocked due to the nearly airtight transformer box and the interior is filled with transformer oil. Due to reasons such as the attenuation of the acoustic signal, the accuracy and effectiveness of these positioning methods have certain technical problems in the absence of intrusion.
