Temperature rise test is a routine test item in the type testing of electrical products, aimed at testing the temperature changes of electrical products and components to determine whether they meet the requirements of the standard. The main purpose of temperature rise testing is to evaluate the temperature changes of electrical equipment and its components during operation, ensuring their safety and reliability under high temperature conditions. This type of testing is particularly important for situations such as new product finalization, production process changes, or changes in main component materials. ‌

Purpose of temperature rise test

Ensure product safety: Through temperature rise testing, the temperature changes of the product during actual use can be detected, preventing risks such as insulation material performance degradation, electric shock, burns, or fires caused by excessive temperature.

Evaluating product performance: Temperature rise testing helps evaluate the durability and reliability of products under temperature changes, ensuring their stability and safety under various working conditions.

Method and process of temperature rise testing

Determine the tested components: Select the equipment components that need to be tested.

Install thermocouple: Paste the thermocouple onto the surface of the tested component.

Equipment operation: Run the equipment at the upper limit of rated voltage and frequency, and adjust the output load to the required size.

Reaching thermal equilibrium: Keep the device working until it reaches thermal equilibrium.

Record data: Record the readings of thermocouples to assess temperature rise.

Application areas and importance of temperature rise testing

Temperature rise testing is widely used for safety performance testing of various electrical products, such as power line connectors, sockets, extension cords, conversion plugs, wiring terminals, connectors, switches, and other electrical connection equipment. With the development of electrical equipment, temperature rise testing has become increasingly important for ensuring the safe and stable operation of products.
