Embodiment Construction

[0021] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0022] Such as Figure 1 to Figure 3 As shown, according to an embodiment of the present invention, a temperature sensor is provided. The temperature sensor is used to detect the temperature of the power transmission line 200 . The temperature sensor includes a test contact surface 10, and the test contact surface 10 is a concave curved surface.

[0023] Applying the technical scheme of the present invention, the staff installs and connects the temperature sensor on the power transmission wire to measure the temperature of the power transmission wire. The staff improved the test contact surface of the temperature sensor that is in contact with the surface of the power transmission wire into ...

Abstract

The invention provides a temperature sensor and a conducting wire temperature measuring system comprising the same. The temperature sensor is used for detecting the temperature of a power transmission conducting wire and comprises a testing contact surface, wherein the testing contact surface is a concave curved surface. By adopting the technical scheme of the invention, the contact area of the testing contact surface of the temperature sensor and the surface of the power transmission conducting wire is increased, so that the perception sensitivity of the temperature sensor on the temperature change of the power transmission conducting wire is improved, and the measuring accuracy of the temperature sensor on the temperature of the power transmission conducting wire is improved.

Description

technical field [0001] The invention relates to the field of repair and maintenance of electric equipment, in particular to a temperature sensor and a wire temperature measuring system with the same. Background technique [0002] With the improvement of living standards, people's electricity consumption has increased sharply, leading to an increase in the transmission load of the power grid, resulting in an increasing current flowing through the wires, and the resulting temperature rise of the wires is also becoming more and more serious. Therefore, it is necessary for the electric power maintenance department to measure the temperature of the cables (ie conductors) and perform necessary maintenance on the power grid according to the temperature detection results. This involves the improvement of the temperature sensor used to measure the temperature of the wire. In the prior art, the contact surface of the temperature sensor in contact with the wire to be measured is flat,...
