The invention discloses heating cable heating and cooling cycle life test equipment and a test method, comprising a test platform (1) and a control cabinet (2), and a sample plate (7) for placing a cable sample to be tested is arranged on the test platform (1). ), the top of the sample plate (7) is provided with a cold plate (5) and a hot plate (6) arranged parallel to it, and the sample plate (7) can be arranged along the guide rail ( 4) Horizontal movement, there is also a lifting device under the sample plate (7) to drive it to move in the vertical direction to contact with the cold plate (5) or the hot plate (6). This equipment can simulate the working aging effect of several years and test the product life and quality in a short period of time. It is easy to use, has good test stability and accuracy, and is of great significance to improving the technology and quality of heating cable products and promoting the development of the heating cable industry. Significant, it can be promoted and applied on a large scale.
Description
technical field [0001] The invention belongs to the technical field of testing, and more specifically relates to testing equipment and a testing method for heating cable cold and hot cycle life. Background technique [0002] Heating cable products are not only widely used in civil occasions, including electric floor heating, water pipe antifreeze, roof snow melting, etc., but also widely used in industry, especially in the insulation and heating of various industrial pipes and tanks. After the cable is put into operation, it will be aged due to the effects of cold and heat factors, which will affect the operation reliability and service life of the cable. There are various types of heating cables on the market, and their service life is an important indicator of quality. However, in the prior art, the service life is often estimated through theoretical deduction, which is difficult to ensure accuracy and stability, and difficult to reflect The real service life of the heati...
