| The characteristics of transmission line in Hohhot is the main line of the long distance line, and more perplexing, influenced by surroundings or external damage failure in line and tower, which can master the real-time state of lines, but also in line failure alarm the first time, this paper designs a set of power transmission line monitoring system, and the system deployment in Hohhot Power Supply Bureau under the jurisdiction of the high-voltage transmission line, real-time monitoring of short circuit grounding, break, over temperature, destroyed by the external fault and indicated on the map, to ensure the operation of the transmission line personnel to understand the real-time running state, to prevent failure, improve the efficiency of failure handling. This paper takes Hohhot power transmission line as the object, through the research of on-line monitoring technology of transmission line, combined with the actual situation of Hohhot power transmission line monitoring and testing index, choose the type of formulation of relevant parameters of the system hardware design structure, test instrument, communication mode, and the software design of each function module of the. Based on the electronic measurement technology, wireless communication technology and software technology, the transmission line on-line monitoring system which can be applied to the Hohhot area was developed. Hohhot power transmission line on-line monitoring system can realize on line conductor icing degree, the temperature of the wire, overhead line sag, tilt, vibration; contamination insulator strings; tower tilt, vibration and damage by external forces; the surrounding environment, meteorological image (video) online monitoring function of the system is. A real-time and effectively prevent the occurrence of major disasters. |
