System and method for testing performance of copper core low-voltage cable after manufacturing and processing

Abstract

The invention provides a system and a method for testing the performance of a copper core low-voltage cable after manufacturing and processing, and the system comprises a double-item detection mechanism, a single-item detection mechanism and a joint control mechanism. Since an existing cable mechanical performance testing device can only test the cable of one model and size, when mechanical performance testing is carried out on cables of different models and sizes, testing can be carried out only by replacing devices of corresponding models, and mechanical performance testing of the cables has limitation and is high in testing cost; and testing of the mechanical performance of the cables is divided into a plurality of specific small testing, and the existing testing device for the mechanical properties of the cable cannot meet the operation execution of various tests, is difficult to ensure the comprehensive detection of different mechanical properties of the cable, and cannot meet the strict test requirements of various properties of the cable after being manufactured and processed, and the like.

Description

technical field [0001] The invention relates to the technical field of cable mechanical performance testing, in particular to a performance testing system and testing method for copper core low-voltage cables after manufacture and processing. Background technique [0002] Copper core low-voltage cables are made of one or more mutually insulated conductors covered with insulation and protective layers to transmit power or information from one place to another. Copper is the main conductor material used in cable products; copper Core low-voltage cables are cables used to transmit and distribute electric energy. Copper-core low-voltage cables are often used in urban underground power grids, power station lead-out lines, internal power supply in industrial and mining enterprises, and underwater transmission lines across rivers and seas. At present, with the development of society and economy, cables The consumption is growing rapidly, and the quality requirements for cables are ...

Problems solved by technology

[0004] Today's test equipment for cable mechanical properties can only meet the test requirements for cables of one type and size. When the mechanical properties of cables of different sizes are tested, it is necessary to replace the corresponding type of equipment to perform the test, so that the mechanical properties of the cable The test has limitations, the test cost is high, and the test of the mechanical properties of the cable is divided into many specific small tests. However, the current test equipment for the mechanical properties of the cable cannot meet the operation and execution of various tests, and it is difficult to ensure that the mechanical properties of the cable are different. The comprehensive testing of performance cannot meet the strict performance testing requirements of cables after manufacturing and processing; therefore, the present invention provides a performance testing system and testing method for copper core low-voltage cables after manufacturing and processing
