Embodiment Construction

[0025] Attached below figure 1 The present invention is described further:

[0026] Such as figure 1 As shown, a) power line surface pretreatment: remove the oil and dirt on the surface of the detected power line after polishing, then wash with deionized water and finally dry;

[0027] (b) Fix and clamp the detected power line with the power line clamp, simulate the force on the in-service power line clamp, and establish the force model of the above-mentioned detected power line;

[0028] (c) Determine the core stress points of the above-mentioned power line clamps, and add constraints;

[0029] (d) Determine the detection method: detect the parameters such as the outer diameter of the detected power line, the groove diameter, and the wall thickness difference through electromagnetic waves;

[0030] (e) Ultrasonic testing: testing the material of the detected power line material and the depth of defect cracks by ultrasonic testing;

[0031] (f) Establish the relevant stand...

Abstract

The invention discloses a power line clamp detection method. Simulation stress is performed on an on-service power line clamp through a power line clamp, an electromagnetic detecting method and an ultrasonic detecting method are formulated, the power line clamp is detected and monitored periodically, the phenomenon that accidents happen when the line clamp is broken is avoided, economic losses are avoided, the detection precision can be effectively improved, and the stability is high.

Description

technical field [0001] The invention relates to a detection method, in particular to a power line clamp detection method. Background technique [0002] The power line fault indicator is a device used in transmission and distribution lines, power cables and switchgear inlet and outlet lines to indicate the flow of fault current. Once a fault occurs on the line, the line inspectors can use the alarm display of the indicator to quickly determine the fault point and eliminate the fault, changing the backward practice of blindly inspecting the line and switching on and sending power in sections to find faults in the past. However, the traditional fault indicator adopts analog circuit technology and small shell packaging design, the realization function is too simple, the type of fault detection is too single, and it needs on-site inspection by line inspectors, and it is impossible to realize remote fault alarm. Limitation, once adopting the spot check method and replacing it wit...
