The device comprises anoil temperature gauge, an oil level gauge, an acquisition device, an optical modulator, a photoelectric converter, a filter, and a management terminal; the oil temperature gauge and the oil level gauge are arranged on a transformer; the acquisition device is used for acquiring oil temperature information and oil level information of the transformer; the optical modulator is located on the side ofthe acquisition device; the photoelectric converter is located on the side of a main control chamber; the filter is located on the side of the photoelectric converter; the management terminal is located in the main control chamber; the oil temperature gauge is connected and communicates with the acquisition device; the oil level gauge is connected and communicates with the acquisition device; theacquisition device is connected and communicates with the optical modulator; the optical modulator is connected and communicates with the photoelectric converter; the photoelectric converter is connected and communicates with the filter; and the filter is connected and communicates with the management terminal. Through the oil temperature gauge, the oil level gauge, the acquisition device, the optical modulator, the photoelectric converter, the filter, and the management terminal, oil leakage of the transformer can be judged quickly, accurately and timely.

Description

technical field [0001] The invention relates to the technical field of power transformer monitoring equipment, in particular to a transformer oil leakage monitoring device based on oil level monitoring. Background technique [0002] The transformer is the core unit of power transmission, which directly affects the stability of the power system. In the actual operation process, the oil leakage of the transformer may lead to the reduction of internal insulation and affect the normal operation of the transformer. Therefore, how to detect the oil leakage of the transformer in time and deal with it in time is the focus of the power system. [0003] Investigation and research found that most of the existing technology patents use ultraviolet light source and chromatograph for detection, that is, the ultraviolet light source is irradiated on the transformer oil to stimulate fluorescence, and the spectral image is collected by the chromatograph, and then the area of ​​the leaked oil...

AI Technical Summary

Problems solved by technology

[0005] First, the monitoring area is relatively limited, especially in the field of UHV transformers, it is difficult to achieve comprehensive monitoring, especially UHV transformers have their own soundproof covers

[0006] Second, due to the cobblestones laid around the main transformer, it is difficult to actually measure the area and amount of oil leakage

[0007] Third, ultraviolet light is harmful to human health and hinders the normal inspection of equipment maintenance personnel
