Problems solved by technology

However, in the actual working environment, it is affected by factors such as oil mist, heat, radiation, machinery, etc., especially when in use, the cable is often dragged, and when the cable is erected, its own gravity acts on the cable itself , which often causes the cable to break, thereby reducing the service life of the cable
[0004] However, in the existing technology, there is a lack of testing equipment for the service life of the cable, and it is often impossible to effectively judge the service life of the cable in the early stage. Once the cable fails during use, the normal transmission of power will be interrupted, causing The failure of the electrical system will cause the stagnation of industrial production, and even cause safety accidents in severe cases. Therefore, a large amount of manpower and financial resources are needed for detection and repair, which is costly and inefficient.

The detection machine is simple in structure, reasonable in layout, simple and convenient to operate, and capable of effectively detecting the service life of the cable.

Description

technical field [0001] The application relates to the field of cable quality inspection equipment, in particular to a cable service life detector. Background technique [0002] At present, with the gradual improvement of social automation, the electrical system is also becoming more and more complex. Cables undertake the important task of transmitting electrical energy and signals, and are widely used in various mechanical and electronic fields. Since the service life of the cable directly affects the safety of production, the safe service life of the cable is especially important in practical applications. [0003] In the existing relevant technical specifications, there is no clear requirement on the service life of the cable, and the safe service life of the cable design generally recognized in the industry is 20-30 years. However, in the actual working environment, it is affected by factors such as oil mist, heat, radiation, machinery, etc., especially when in use, the ...
