The temperature measurement principle of the temperature measurement device in the use process can be referred to the related technology of patent publication number CN 105424223A. Specifically, the heat transfer conductive bracket 1, the temperature measuring probe and the conductive equipment box 2 form a whole, after the heat transfer conductive bracket 1 is connected with the power grid contact to be measured, the heat of the power grid contact to be measured can be transferred to the temperature measuring probe, the temperature measuring probe obtains the temperature data of the power grid contact to be measured, and a battery capable of supplying power to the temperature measuring probe can be further arranged in the conductive equipment box 2.

The contacts 13 may be provided in plural, and the plural contacts 13 are arranged at intervals on the inner wall of the notch 12. Therefore, the contacts 13 can have more contact areas with the power grid contact, and the use effect of the temperature measuring device is ensured.
