Real-time monitoring device for oil quality of power transformer

Abstract

The invention discloses a real-time monitoring device for oil quality of a power transformer, and relates to the technical field of electrical equipment monitoring. The real-time monitoring device for the oil quality of the power transformer comprises a plurality of liquid pools, an infrared light generator and a processor, wherein the liquid pools are used for containing oil and comprise first window pieces and second window pieces which are arranged in parallel, the distance between the first window piece and the second window piece is a pool distance; the infrared light generator is used for irradiating oil between the first window piece and the second window piece to obtain infrared light beam data; and the processor is used for acquiring and analyzing the infrared beam data to obtain oil quality information. According to the invention, the oil in the transformer can be detected and analyzed, the aging degree of the oil is reflected, and the real-time monitoring of the transformer oil is realized.

Description

technical field [0001] The invention relates to the technical field of electrical equipment monitoring, in particular to a real-time monitoring device for oil quality of a power transformer. Background technique [0002] Power transformer is the most important core part of smart grid, and its normal operation is the fundamental guarantee of grid security. The transformer is the heart of the substation, not only one of the most important and expensive equipment in the power system, but also one of the most accident-prone equipment in the power system. Its operational reliability directly affects the normal production of the power industry. The quality of transformer oil operation and the degree of aging are directly related to the safe operation and service life of the transformer. Transformer oil will inevitably be affected by various factors such as electricity, heat, machinery and environment during operation, and will age and decompose, resulting in continuous deteriora...

Problems solved by technology

Transformer oil will inevitably be affected by various factors such as electricity, heat, machinery and the environment during operation, and will age and decompose, resulting in continuous deterioration of its performance, affecting the insulation state of the transformer, and causing hidden dangers to the safe and stable operation of the transformer.

[0003] At present, the quality monitoring of transformer oil is mainly through routine pre-testing, that is, regularly going to the site to collect oil samples, analyzing them in the laboratory, and evaluating the quality of transformer oil. However, the experimental items and test cycle of the pre-testing have great limitations. , the oil quality test is basically carried out for three years or even when necessary, and the mutation process of oil deterioration cannot be discovered in time, and it is time-consuming and labor-intensive
