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 temperature measurement device used for detecting high voltage cable temperature, comprising a temperature detection unit, a clamping seat, a clamping head and a spring; the housing of the temperature detection unit is provided with a clamping seat; the housing of the temperature detection unit is integrated with the clamping seat by pouring epoxy resin; the housing of the temperature detection unit is provided with a groove matching with the shape of the cable;the clamping head is connected to the clamping seat through a cotter pin; the clamping head is provided with a groove matching with the appearance of the cable on the position corresponding to the groove on the temperature detection unit; and the clamping head is provided with the spring. The cable, the temperature of which is to be measured, is placed between the housing of temperature sensor and the clamping head; the cable is clamped through the clamping head, which limits the randomness of installation of the temperature sensor, improves the installation quality, and avoids the temperature error caused by non-standardized installation. The temperature measurement device is simple in structure, small in volume and easy in installation.
Description
technical field [0001] The invention belongs to the field of electric power detection, and in particular relates to a temperature measuring device for detecting the temperature of a high-voltage cable. 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 temperature measuring device for detecting the temperature of a high-voltage cable with a simple structure and convenient detection. [0004]...
