Problems solved by technology

[0003] The traditional cable temperature measuring device tends to shake the object to be measured left and right during the temperature measurement process, and the temperature measurement accuracy will be directly affected. The measurement error is large, which cannot meet the actual measurement requirements. Therefore, a power cable temperature measurement device is redeveloped to solve the above phenomenon

Embodiment 1

[0020] Such as Figure 1-2 As shown, in the embodiment of the present invention, a power cable temperature measuring device includes a support push seat 1, and a push handle 6 is provided at the middle of the base surface of the support push seat 1, and the support push seat 1 starts from the left To the right, there are three groups of No. 1 clamping temperature measuring mechanism 2, No. 2 clamping temperature measuring mechanism 3 and No. 3 clamping temperature measuring mechanism 4 with the same structure, and No. 1 clamping temperature measuring mechanism 2 and No. 2 clamping temperature measuring mechanism Between the temperature measuring mechanism 3, the No. 2 clamping temperature measuring mechanism 3 and the No. 3 clamping temperature measuring mechanism 4 are fixed together by two sets of auxiliary connecting rods 5. Since the No. 1 clamping temperature measuring mechanism 2 and the No. 2 clamping The temperature measuring mechanism 3 and the No. 3 clamping temperat...

Abstract

The invention provides a power cable temperature measurement device. By improving a traditional cable temperature measurement device, and adding three clamping temperature measurement mechanisms, namely the first clamping temperature measurement mechanism, the second clamping temperature measurement mechanism and the third clamping temperature measurement mechanism, which are identical in structure, in actual use, an electrical engineer only needs to place the device under a to-be-measured power cable, and the power cable is synchronously lifted by using the tops of three main supporting columns; at this moment, after an upward force is applied through a supporting push base, a vertical push rod pushes a horizontal push-pull plate to walk upwards a distance, and an elastic compressed spring is directly squeezed and compressed. Because of the design of special structures of a force application connecting rod, a rotating push arm and a hinging base, the rotating push arm in the horizontal direction can be slowly lifted up under the action of the force application connecting rod in the upward moving process of the horizontal push-pull plate.

Description

technical field [0001] The invention relates to the field of electric equipment, and more specifically, relates to a power cable temperature measuring device. Background technique [0002] With the development of the power system, the voltage and current of the cable load are constantly increasing, which will inevitably lead to the temperature rise of the cable close to the limit temperature; when the cable joint and the power system work abnormally (such as overload, short circuit trip, etc.), the cable The temperature rise of the cable may also be abnormal; how to use an effective method to monitor the temperature change of the cable during work and operation is an important issue to ensure the safety of the power system, and it is of great significance to the production and life of using electricity. [0003] The traditional cable temperature measuring device tends to shake the object to be measured left and right during the temperature measurement process, and the temper...
