Problems solved by technology

[0002] The number of power outages caused by insulation faults in high-voltage transmission lines is high, and the insulators of transmission lines are the weak link in the insulation of high-voltage transmission lines. In the harsh environment of rain, humidity and dirt, flashover often occurs due to surface pollution or lightning strikes on the line. The flashover of the insulator will lead to short circuit grounding, which will not only burn out the insulator, but also cause the circuit breaker of the substation to trip. Short-term or long-term power outages will cause heavy losses. Therefore, the power department must always know when and where flashovers occur on the insulators of high-voltage transmission lines, so that the staff can repair and maintain the lines in time. For this reason, we Propose an on-line monitoring system for transmission line insulator flashover

Abstract

The invention relates to the technical field of power transmission line monitoring, and discloses an online monitoring system for a power transmission line insulator flashover. The system comprises acontroller, a flashover current sensor, a communication module, a remote control terminal, a display module and an alarm module; the output end of the flashover current sensor is electrically connected with the input end of the controller; the output end of the controller is electrically connected with the communication module, the display module and the alarm module; and the output end of the communication module is wirelessly connected with the remote control terminal. According to the system, flashover signals of an insulator are collected by the flashover current sensor, the acquired signals are displayed and transmitted in real time through the controller, and the data information can also be wirelessly sent to the remote control terminal through the communication module, so that a worker can conveniently monitor flashover information in real time, an alarm signal is sent out, the worker can receive the alarm information at the first time, and the worker is reminded to repair a power transmission line in time.
