Power frequency spark testing machine for on-line detection of cable

Abstract

The invention relates to the technical field of cable on-line detection, in particular to a power frequency spark testing machine for on-line cable detection, which comprises a workbench and four supporting legs, the four supporting legs are respectively fixed at four corners of the bottom of the workbench, and an adjusting assembly is arranged among the four supporting legs. A detection box is installed in the middle of the top of the workbench, plug wire holes are formed in the outer walls of the two sides of the detection box, a detector used for detecting cables is installed in the detection box, rectangular grooves are formed in the positions, located on the two sides of the detection box, of the top of the workbench, and two round holes are formed in the peripheral wall of the workbench. The two circular holes are communicated with the two rectangular grooves respectively, clamping assemblies are installed in the rectangular grooves, the clamping assemblies are aligned with the wire inserting holes, locking assemblies are installed in the circular holes, and universal wheels are fixed to the bottoms of the supporting legs.

Description

technical field [0001] The invention relates to the technical field of on-line detection of cables, in particular to a power frequency spark testing machine for on-line detection of cables. Background technique [0002] The spark testing machine is an on-line testing equipment that is placed in the take-up part of the wire product during the production of wire and cable. The voltage value is periodically loaded on the insulating wire according to a certain law, and the conductor part is grounded, so that a voltage difference is formed between the conductor and the insulating surface, so that whether the insulating layer is defective can be detected, so that the wire and cable products are qualified to leave the factory. [0003] The spark test is mainly used to detect whether there are defects such as pinholes, impurities and lack of glue in the insulation or sheath of wires and cables. When the existing spark tester is in use, there is no equipment for lifting the line, whi...

Problems solved by technology

[0003] The spark test is mainly used to detect whether there are defects such as pinholes, impurities, and lack of glue in the insulation or sheath of the wire and cable. When the existing spark testing machine is in use, there is no special equipment for lifting the line, which makes most of the area of ​​the line Friction with the detection board, resulting in damage to the circuit and affecting the detection effect
