Adaptability Study On Test Method Of Insulation Performance Of Pipe Insulation Joint (Flange)

Pipe insulation device of electric insulation performance directly influences the steel pipeline cathodic protection effect,with the continuous development of detecting technology at home and abroad,in view of the existing oil and gas,chemical industry pipeline insulation device of electric insulation performance detection technology cannot be well applied to the present situation of the real industrial environment,in order to improve the electric insulation pipe insulation device performance testing technology of field application requirements,the comprehensive application of various kinds of electric insulation performance testing technology,put forward a set of can in a real environment to test the electric insulation performance of pipeline insulation device.Papers on electric insulation performance test methods were studied,to produce a set of pipeline insulation device electrical insulation tester,simulation tests in the actual gas pipeline environment,reliability and practicality of the proposed method is validated through reached in the real industrial environment for electrical insulating pipe insulation device performance for testing purposes.This paper studies the existing electric insulation performance testing methods,comparison methods advantages and disadvantages.In view of the existing electric insulation performance testing methods,summarizes the shortcomings and puts forward a new set of electric insulation test method.Through the test,calculation,and compare to the qualitative test electric insulation performance of the instrument test results,verify the electrical insulation test the reliability of the new method.By comparing a variety of oscilloscope waveform diagram,select more suitable for the actual production of oscilloscope as dedicated oscilloscope in the electric insulation performance testing system.Produce electric insulation performance testing system,use a dedicated oscilloscope as analog signal generator,respectively in the laboratory environment,field environment verify the effectiveness of the electric insulation performance testing system test results.Data into the PC,shows that the leakage rate in the upper machine,the quantitative judgment electric insulation performance is good or bad.Finally,with the green line in and out of the station insulation device electrical insulation test,determine its insulation performance.
