Related electrical fires have also occurred frequently, resulting in Great loss of life and property of the country and people.
引起电气火灾，最直接的因素是电气设备运行过程中的温升，因此，在CCC认证试验过程中，设备通电运行情况下的温升试验显得尤为重要。The most direct factor causing electrical fires is the temperature rise during the operation of electrical equipment. Therefore, during the CCC certification test, the temperature rise test under the condition of the equipment running with electricity is particularly important.

It can only display the data of all sampling points in real time and record the sampling data in an Excel form. When doing the temperature rise test, it may be necessary to detect the temperature of 100 points at the same time. The test can only be carried out when the temperature changes of 100 points within one hour are all within 1°. However, relying on manual judgment of the temperature changes of these 100 points may not only cause errors due to too much data, but also take a long time. When the judgment is completed, the time limit may be exceeded, which brings many uncertain factors to the test.
因此，有必要提供一种新的电气设备温升试验系统及其试验方法以解决上述问题。Therefore, it is necessary to provide a new electrical equipment temperature rise test system and its test method to solve the above problems.
