Abstract

The invention relates to a CT-based nondestructive testing device and method for an insulated piercing wire clamp. The device and method are technically characterized in that an X-ray of CT is used for penetrating through the insulated piercing wire clamp, and an X-ray receiver is used for receiving a signal; a motor is used for controlling axial and circumferential movement to realize CT; and the received signal is analyzed by a computer to realize 3D image reconstruction of the internal structure of the insulated piercing wire clamp, so that the aim of nondestructive testing is fulfilled. The device and method can accurately and reliably master the internal structure of the insulated piercing wire clamp, analyzes the contact condition of the insulated piercing wire clamp, effectively evaluates the insulated piercing wire clamp, is of a great significance in improving the reliability of insulation wires of a middle and low voltage distribution network, and greatly improves the power supply reliability of the middle and low voltage distribution network.

Description

technical field [0001] The invention belongs to the technical field of contact state detection of insulation puncture wire clips of medium and low voltage distribution networks, in particular to a non-destructive detection device and method for insulation puncture wire clips based on CT tomography. Background technique [0002] At the end of July 1986, the "Notice on Strengthening the Work of Urban Distribution Networks" issued by the former Ministry of Energy clearly pointed out that urban medium and low voltage distribution networks should actively adopt and promote overhead insulated conductors, especially in prosperous areas of cities, densely populated areas and In areas where the contradiction between tree lines is prominent, the overhead insulated wires will gradually replace the existing overhead bare wires. At present, insulated conductors are used in the main medium and low voltage distribution lines in large and medium-sized cities, and how to connect and branch o...
