Abstract

The invention relates to an online monitoring device, method and equipment for the state of a power transmission cable, and the device is in communication connection with data processing equipment, is arranged on the power transmission cable, and comprises a power module, a posture detection module, a temperature detection module and a communication module. The power supply module is used for self-generating power to supply power to the attitude detection module, the temperature detection module and the communication module; the attitude detection module is used for collecting three-dimensional space data of the power transmission cable in real time; the temperature detection module is used for collecting the temperature of the power transmission cable in real time; the communication module is used for transmitting the collected three-dimensional space data and temperature to the data processing device, and the data processing device is used for judging whether the power transmission cable is damaged and broken at high temperature or not according to the collected three-dimensional space data and temperature and monitoring the state of the power transmission cable. The device is combined with data processing equipment to monitor the swinging posture of the power transmission cable, the cable temperature condition, the condition whether the cable is interrupted or not in real time, and a user can conveniently repair the abnormity of the power transmission cable in time.

Description

technical field [0001] The invention relates to the technical field of power transmission cables, in particular to an online monitoring device, method and equipment for the state of power transmission cables. Background technique [0002] At present, there is no real-time monitoring system for the status of power transmission cables in the power industry, and it is impossible to monitor the swing range of the cables, whether they are disconnected, or the temperature. In the power industry, the inspection and maintenance of power transmission cables is generally carried out in a hollow operation. After each disaster such as typhoon, ice disaster, fire and other erosions, the power transmission cables in the power industry need to be repaired one by one. The project is large and the efficiency is low. If it cannot be processed in time, it will cause power supply problems. For example, when a fire breaks out around a high-voltage line, the temperature of the cable cannot be qu...
