At present,maintenance-free respirators are used to replace traditional respirators in UHV converter transformers.Due to lack of breathing oil cup,the breathing state of oil-immersed equipment can not be judged directly in case of gas circuit blockage.For this reason,the technical principle of spirometer with"electronic lung function"is used for reference to design a portable and convenient conduction detection device,which can detect and read the"breathing state"of respirator through sensing circuit and display the reading on the spot,so it can meet the use needs in daily maintenance and acceptance work of converter transformer,and at the same time,it can significantly shorten the detection time and improve the detection accuracy.Finally,a physical sample of the designed detection device is manufactured and installed on the respirators in converter trans-formers.The effectiveness of its conduction detection is verified by experiments.
