Ultrasonic Non-destructive Qualification on the Quality of Integration of Suspension Insulator Pin with Zinc-sleeve |
| |
| Abstract: | A kind of new detecting technique and equipment,which can evaluate the complex quality of integration of suspension insulator pin with zinc sleeve,is introduced at the first time in details.In virtue of statistical control theory,the echo amplitude is analysed and processed in order to obtain the criterion indicating the zinc sleeve integration which is verified by metallograph quality.The results show that it is feasible to apply the kind of detecting technique and equipment to realize the non destructive evaluating to the quality of the zinc ring radically. |
