Problems solved by technology
[0002] During the long-term operation of high-voltage cable joints in power systems, problems such as surface oxidation and corrosion, loosening of fastening bolts, aging of contacts and busbar connections often occur, resulting in overheating of equipment and even serious accidents
When workers install the cable temperature sensor, it often happens that the installation is not correct and the error of the detected temperature is too large, which affects the accuracy of the detected temperature and misses the best time to find the fault

The invention provides a high voltage cable temperature measuring device. The high voltage cable temperature measuring device includes a hanging shaft, a clamping head, a temperature detection unit and a screw, wherein the clamping head is arranged on the hanging shaft; the cross section of the clamping head is U-shaped; the temperature detection unit is arranged on the hanging shaft; the housing of the temperature detection unit is integrated with the epoxy resin for the clamping head through casting; the housing of the temperature detection unit is provided with a groove which matches with the profile of the cable; a screwed hole is formed in the bottom of the clamping head; the screw is arranged in the screwed hole; as the cable which waits to measure the temperature is arranged between the hanging shaft and the clamping head and the screw in the clamping head clamps the cable, the randomness for the temperature sensor during the mounting process is limited; the mounting quality is improved; and the temperature measurement error caused by nonstandard mounting can be completely avoided. The high voltage cable temperature measuring device has the advantages of being simple in structure, being small in volume and being convenient to mount.
Description
technical field [0001] The invention belongs to the field of electric power detection, in particular to a high-voltage cable temperature measuring device. Background technique [0002] During the long-term operation of high-voltage cable joints in power systems, problems such as surface oxidation and corrosion, loosening of fastening bolts, aging of contacts and busbar connections often occur, resulting in overheating of equipment and even serious accidents. When workers install the cable temperature sensor, they often install it incorrectly, which makes the detected temperature error too large, affects the accuracy of the detected temperature, and misses the best time to find the fault. Contents of the invention [0003] The problem to be solved by the present invention is to provide a high-voltage cable temperature measuring device with simple structure and convenient detection. [0004] In order to solve the above technical problems, the technical solution adopted in t...
