Abstract

An embodiment of the present invention provides an on-line monitoring device for the moisture content of transformer insulating oil, including: an oscillation frequency counter, an oil sample constant temperature detection chamber, and a crystal oscillator; The detection chamber is used to generate the oscillation frequency and transmit it to the oscillation frequency counter; the oil sample constant temperature detection chamber is equipped with the crystal oscillator inside, which is used to hold transformer insulating oil; the oscillation frequency counter is connected to the crystal oscillator connected to record the oscillation frequency generated by the crystal oscillator, and obtain the moisture content of the transformer insulating oil according to the change of the oscillation frequency generated by the crystal oscillator. The embodiment of the present invention also provides an online monitoring method for the moisture content of transformer insulating oil, and the method is realized by the device. The invention can quickly, conveniently and accurately monitor the water content in the insulating oil of the transformer on-line.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of transformer insulating oil performance monitoring, and in particular to an on-line monitoring device and method for moisture content of transformer insulating oil. Background technique [0002] The performance of transformer insulating oil is directly related to the safe operation and service life of transformers. Trace moisture content in transformer insulating oil is one of the main factors affecting the insulation strength of oil products. By detecting the moisture content in the transformer insulating oil, not only can the insulation strength of the transformer insulating oil be prevented from being reduced to a dangerous level, but also the overall insulation condition of the transformer can be evaluated. [0003] At present, my country's electric power industry mainly uses coulometric method and chromatography to detect the moisture content in transformer insulating oil. ...
