Portable insulation shielding fabric flaw testing method and testing instrument

Abstract

The invention relates to a portable insulation shielding fabric flaw testing method. The portable insulation shielding fabric flaw testing method is characterized by comprising the steps that firstly, high-definition image collecting is carried out on insulation shielding fabric, and flaw parts are marked; secondly, whether the insulation performance of the flaw parts meet the standard or not is detected in a gradually-pressurizing mode. A flaw testing instrument comprises a suspension support, a handheld lighting scanner, a double-coordinate numerical control infrared laser locking device, a combined control box, a display screen and a permanent magnet probe. The handheld lighting scanner is used for collecting a high-definition image of the outer surface of the insulation shielding fabric. The image is displayed through the display screen, and the combined control box is used for measuring the insulation performance by changing the voltages applied to the two sides of the permanent magnet probe. By means of the insulation shielding fabric flaw testing method and the testing instrument, the problems that observation conducted merely through the human eyes is inaccurate, and the flaw parts cannot be scientifically measured through a megger are solved, the shielding fabric with the potential insulation issue can be detected out, the personnel safety of live line working personnel is ensured, the advantages are obvious, and the insulation shielding fabric flaw testing method and the testing instrument are suitable for application and popularization.

Description

technical field [0001] The present invention relates to a portable insulating and protective fabric defect testing method and tester, more specifically, to a testing method and tester that can realize the non-missing detection of insulating and protective fabric defects. Background technique [0002] Insulating protective fabrics (such as insulating isolation clothing, insulating isolation shawls, insulating isolation blankets, etc.) are used in high-voltage live working occasions to isolate workers from charged bodies and protect them from high-voltage damage. Since the 10kV high voltage of the distribution network has a strong penetrability, this requires that the insulating protective fabric must be intact. Once there is damage or scratch, the high voltage will break down instantly through the damage, causing extreme damage to the on-site staff. big damage. [0003] Therefore, this requires the staff to check and detect the insulating and protective fabrics worn or u...

AI Technical Summary

Problems solved by technology

Some of the existing inspection methods use the form of visual inspection to check whether there are scratches or damages from the appearance. If there are any scratches or damages, they cannot be used for live work; The insulation performance of the inner and outer surfaces of the protective fabric is measured. Since the protective fabric itself is an insulating material, where and how to use the probe of the shaker to measure are the problems faced in actual use. As a result, there is no scientific, reasonable, The measurement method used can realize the on-site inspection and measurement of the insulation performance of the insulating protective fabric without omission, ensuring the safety of the staff
