The main function of the temperature rise test equipment is to test the temperature rise of the electrical components of the power system, that is, the type test. For example, large current temperature rise test for circuit breakers, switch cabinets, jp cabinets, center cabinets, etc.
For example, one of the test items that must be passed before the low-voltage power distribution cabinet is produced is the temperature rise test, which is to check whether the temperature rise of the low-voltage power distribution cabinet and related parts meets the requirements of relevant standards. How to understand the temperature rise is actually the temperature generated by the low-voltage power distribution cabinet during use. As the power distribution cabinet uses time, this temperature will also change. When the temperature exceeds the relevant standards, it will have a destructive effect on the product.
The hazard of temperature rise. If the temperature rise exceeds the standard, it will have a great impact on the performance of the insulating parts and the life of the low-voltage power distribution cabinet. The frequent temperature rise exceeding the relevant standard will greatly reduce the insulation performance, so it is easy to cause insulation breakdown accident. In addition, severe heating may cause the explosion of the low-voltage power distribution cabinet, because the circuit breakers in the low-voltage power distribution cabinet are sealed, and the gas in the cabinet cannot be discharged, and the frequent temperature rise may exceed the standard, which is very easy to cause an explosion.
