Problems solved by technology
[0002] The 10kV cable intermediate joint is soaked in accumulated water for a long time. When the cable line is cut off for a long time, the internal structure of the intermediate joint enters water vapor due to thermal expansion and contraction, and the insulation performance decreases, resulting in breakdown; it is impossible to dynamically monitor the relevant parameters of its operating status , timely detection of pre-failure symptoms

The invention relates to the technical field of power cable protection, and relates to a cable intermediate head protection device. Comprises a protective tube, a plugging head, a temperature sensor,a humidity sensor, an acquisition module and a data transmission module, wherein, plugging heads are arranged at both ends of the protective tube, the plugging heads are inserted into the nozzles at both ends of the protective tube and are sealingly connected with the protective tube; A through hole is arranged in the middle of the plugging head, the cable penetrates into the protection pipe fromthe through hole, and the cable and the through hole are sealed and connected with each other through a connecting piece. The temperature sensor, the humidity sensor, the acquisition module and the data transmission module are respectively electrically connected with the acquisition module, and the acquisition module is electrically connected with the data transmission module, and the data transmission module sends the collected data to the background control system. The invention can effectively prevent the cable middle head from being immersed in water, and can also monitor the temperature and humidity of the cable middle head in real time.
Description
technical field [0001] The invention relates to the technical field of power cable protection, and more particularly, to a cable intermediate head protection device. Background technique [0002] The 10kV cable intermediate joint is soaked in accumulated water for a long time. When the cable line is powered off for a long time, the internal structure of the intermediate joint enters water vapor due to thermal expansion and contraction, and the insulation performance decreases, resulting in breakdown; it is impossible to dynamically monitor its operating status related parameters , to detect the symptoms before the failure in time. Contents of the invention [0003] In order to overcome at least one defect of the above-mentioned prior art, the present invention provides a cable intermediate head protection device, which can effectively prevent the cable intermediate head from being immersed in water, and can also monitor the temperature and humidity of the cable intermediat...
