Oil-immersed capacitor oil leakage detection device and method

Abstract

The invention discloses an oil-immersed capacitor oil leakage detection device. The oil-immersed capacitor oil leakage detection device adopts an ultraviolet light source, a first laser frequency screening device, a laser beam splitter, a data acquisition device and a data analyzer, wherein the first laser frequency screening device is used for screening single-frequency ultraviolet light from theultraviolet light source; the laser beam splitter is used for converting single-frequency ultraviolet light into multiple beams of parallel single-frequency ultraviolet light; the data acquisition device is used for receiving ultraviolet light radiated by the capacitor to be detected; the data analyzer is used for receiving the digital signal, and converting the digital signal into image data; the first laser frequency screening device is arranged between the ultraviolet light source and the laser beam splitter; the to-be-detected capacitor is arranged between the laser beam splitter and thedata acquisition device; and the data analyzer is electrically connected with the data acquisition device. The oil-immersed type capacitor oil leakage detection device does not depend on manual inspection, can accurately distinguish stains and oil marks by means of photoelectric conversion, and reduces misjudgment and leakage judgment.

Description

technical field [0001] The invention relates to the technical field of image recognition, in particular to an oil-immersed capacitor oil leakage detection device and method. Background technique [0002] Capacitors are often used in power systems for reactive power compensation and to maintain terminal voltage stability, reduce losses during transmission, and reduce economic losses. They are an important part of power system operation. In order to ensure that the capacitor is not corroded by oxygen and lowers the temperature during operation, insulating oil is often used for internal filling to prevent contact with air and enhance heat dissipation. However, during operation, the insulating oil will leak due to abnormal internal air pressure or device damage. If the leaking oil is not found in time, it will reduce the performance of the equipment, cause safety hazards, and even burn and explode. [0003] At present, the method for checking oil leakage of capacitors is throu...

Problems solved by technology

However, this method is limited by factors such as weather and light, and it is difficult to find the initial characteristics of the fault when the observation conditions are insufficient.

In addition, the experience requirements of the staff are relatively high, and it is necessary to distinguish the traces of dirt and oil, which is easy to cause confusion, misjudgment, missed judgment, etc.
