Transformer oil leakage monitoring and alarm device

Abstract

The invention provides a transformer oil leakage monitoring and alarming device and method. The device includes a weighing platform, a support rod, a control box and a wireless transmitting antenna. The upper surface of the weighing platform is a slope. Made of organic polymer composite materials; the control box is equipped with a power supply module, a weighing module, a computing module and a wireless communication module. The weighing module includes a sensor, an amplifier circuit and an A / D conversion module. The lower surface is connected, and the output end of the sensor is connected to the operation module through the amplification circuit and the A / D conversion module in turn, and the operation module is connected to the wireless communication module. The method includes the following steps: measuring the weight at T1; measuring the weight at time T1+T; calculating the increased weight H within the T time; judging the oil leakage of the transformer according to H and the set value h. The invention has low cost and is convenient to use, and can accurately judge the oil leakage condition of the transformer.

Description

technical field [0001] The invention relates to transformer safety monitoring technology, in particular to a transformer oil leakage monitoring and alarming device and method. Background technique [0002] Most high-voltage transformers are oil-immersed transformers, that is, the main box of the transformer is filled with transformer oil. The main function of the transformer is the insulation and heat dissipation of the transformer winding, iron core and other components, which play an important role in the safe and reliable operation of the transformer. Oil leakage from transformers in long-term operation is inevitable, and a small amount of oil leakage generally does not affect the operation of the transformer. In order to ensure continuous and reliable power supply, oil leakage in general transformers will not be treated in a power outage, and inspection and monitoring should be strengthened. When oil leakage develops into oil leakage or even a large amount of oil leakag...

AI Technical Summary

Problems solved by technology

The gradual increase of oil leakage may develop into oil leakage. The process of oil leakage from oil leakage to oil leakage is unpredictable, and the development time is also unpredictable. It can be as short as a few minutes or as long as several years. If the monitoring is not timely, it may cause Transformer oil leakage endangers operation safety

[0003] The existing solution is to use manual patrol monitoring, which is labor-intensive and consumes a lot of manpower and material resources. On the other hand, manual patrol monitoring is not timely enough, which may cause transformer oil leakage to be undetected and endanger operation safety.
