The temperature rise test is one of the important tests for the safety performance of electronic and electrical products, and it is used to evaluate the quality and electrical safety characteristics of electrical products. When electrical products are in normal use, due to the heat generated by some high-current components, their temperature rises too high. Working in this state for a long time may reduce the performance of insulating materials, resulting in electric shock, burns or fire hazards. Temperature rise test is an important way to detect and avoid these dangers.

To put it bluntly, basically, as long as the electronic appliances and equipment are transported with electricity, there is a temperature rise. If the temperature is too high during operation or operation with a certain load and cannot meet the design and standard requirements, there are potential safety hazards. Therefore, the temperature rise test is the most routine test item.

For example, in the plug and socket industry, the temperature rise test of the plug needs some copper fixtures required by the standard, and the socket needs to be tested with the temperature rise plug (copper pin) required by the standard. , the load end and station of the temperature rise tester should be conveniently placed in the wooden box, and the copper fixture and temperature rise plug should be conveniently used for testing.
