Temperature rise test of plug and socket
- Jan 16, 2018 -

The temperature rise of the plug and socket is the difference between the temperature of the test parts and the ambient temperature after the test current is reached for a certain time under certain conditions. The temperature rise test is one of the important items in the plug and socket type test. By checking whether the temperature appreciation of the key components of the plug and socket meets the requirements of the standard, we examine the carrying capacity of the current carrying parts and the rationality of the device in the structural design. If the temperature rise of plug and socket is too high, there will be a risk of electric shock due to softening of insulation components during actual use, and it will also accelerate the aging of insulation materials.


Because the power systems of different countries all over the world are different, the size and size of plug and socket are much different. The test methods of related safety standards are quite different, which brings many puzzles to the design, producers and inspectors of plug and socket.
