The Application Of High Voltage Porcelain Insulators Ultrasonic Flaw In Jingdezhen Power Grid

In the network of high voltage porcelain insulators Jingdezhen porcelain applied ultrasonic flaw detector on the main website,with miniaturization,digital,simple operation,so that the application of porcelain ultrasonic flaw detector work more convenient,efficient and accurate.Ultrasonic flaw detection test performed work in porcelain porcelain insulators have a good match injured monitoring role. From Jingdezhen network ultrasonic flaw detection by a large number of porcelain insulators sampling results of sampling comparison of data,to extend the analysis curve DAC,examples of DAC Atlas analysis typically comprehensive,assessment,diagnosis,location,test subjects porcelain Multi types of internal defects,first-look inner flange and external defects.Comparison of simulations porcelain high voltage and current measurements,porcelain insulators on the existence of internal defects quickly determine,in comparison with standard test block artificial defect is estimated that the defect length and depth appreciated. Jingdezhen network and the actual use of the trial test test a combination of circumstances technical combine various factors interfere with test results revealing porcelain,test defect detecting their various security categories,the analysis of the testing process for interference essential factors for assessing security effective operating life. It was estimated porcelain insulators,as seriously flawed make judgment scrap confirmed treating defect has security risks porcelain insulators before not qualitative find hidden faults,reducing circuit breaker high voltage shutdown due to porcelain insulators fracture caused by safety data analysis guide,increase security and stable operation of network equipment to some extent.
