Method and system for monitoring respirator in transformer

Abstract

The invention provides a method and system for monitoring a respirator in a transformer. The method comprises the steps that a gas flow value output by the respirator in the transformer is collected in real time; a temperature value and a humidity value output by the transformer are collected in real time; the silica gel performance of the preset respirator is obtained according to the model number corresponding to the transformer; according to the silica gel performance, the preset moisture absorption performance curve of the respirator under the working condition of the gas flow value, the temperature value and the humidity value is obtained; according to the collected gas flow value, the collected temperature value and the collected humidity value, the water content curve of current suction gas of the respirator is drawn; and according to the preset moisture absorption performance curve of the respirator and the current suction gas water content curve of the respirator, the operation working condition of the respirator is determined. Through a flow meter which is serial on the respirator in the transformer, the gas flow value of the transformer is output, a silica gel performance curve is analyzed, then whether silica gel in the respirator loses efficacy is judged, and monitoring on the state of existing transformer respirator silica gel is achieved.

Description

technical field [0001] The present invention relates to a power system in the power industry, in particular to a transformer system in the power system, specifically a method and system for monitoring a respirator in a transformer. Background technique [0002] The electric power industry is the leading industry of the national industry, and the stable development of the electric power industry is the basis for the sustainable development of the national economy. The transformer is an important part of the power system, and its operating status directly affects the safety of the system. With the rapid development of ultra-high voltage and ultra-high voltage technology, the capacity and coverage of the power grid have increased, and its failure may cause major harm and impact on the power system and users. [0003] The main function of the transformer respirator is to breathe air with temperature changes and remove impurities and moisture in the inhaled air. It is an importa...

Problems solved by technology

For transformers, if the silicone fails to cause the respirator to fail to work normally, it may cause rupture of the explosion-proof membrane, oil leakage, water ingress or false oil level, and even accidents
