Simulation cable for cable accessory test and method for testing cable accessories

Abstract

The invention provides a simulation cable for a cable accessory test and a method for testing cable accessories. The simulation cable includes a simulation cable body. The simulation cable body consists sequentially from inside to outside of a conductor, an insulating protective layer and a shielding layer. The conductor of the simulation cable body is provided with a ventilation channel at the central portion. The simulation cable for the cable accessory test includes a first simulation cable component and a second simulation cable component. The first simulation component includes a first simulation component body and a male connector. The second simulation cable component includes a second simulation cable component body and a female connector matching the male connector. The male connector is provided with a male connector gas channel and a male connector gas outlet. The female connector is provided with a female connector gas channel and a female connector gas outlet. With the technical scheme of the invention, the same structural function of an actual cable can be gained, the easy assembly and disassembly for product testing are also realized, the efficiency of a product predelivery test is improved and the manufacturing cost is low.

Description

technical field [0001] The invention belongs to the technical field of cable accessories, in particular to a simulation cable used for cable accessory tests and a detection method for cable accessories. Background technique [0002] At present, medium-voltage power cable accessories are mainly cold-shrinkable cable accessories. In the current cable accessories industry, medium-voltage cable accessories mainly use standard power cables for electrical testing after installation. The standard power cable conductors are copper wires or aluminum wires stranded. Solid cylinder with insulation of cross-linked polyethylene. The on-site installation method of the medium-voltage cable accessories is to use the factory pre-expansion to add the plastic support tube, and then pull out the plastic support tube on site to complete. However, because the cold-shrinkable cable accessories cannot be expanded frequently, it is difficult to carry out the factory test of the product, or the cost...

AI Technical Summary

Problems solved by technology

Due to its structure, the existing cold-shrinkable cable accessories need to be installed on the standard power cable with an interference fit with the cable. After the test is done, it is difficult to take it out. Therefore, usually a small amount of factory test is only taken out and installed on the cable for testing. The test is completed. After that, the accessories are scrapped directly

Existing standard power cables cannot be used for a large number of factory tests and full inspections, and the installation is difficult and the test cost is high

In addition, although the existing standard power cables can meet the installation test of cable accessories, they require many cable specifications, but the required length is not large, which makes it difficult to purchase cables, resulting in high cost of factory test of cable accessories
