OPGW光缆绝缘地线抽能取电技术的研究

Study of Induction to Take Power Technology by Insulated OPGW

OPGW光缆和架空地线按照绝缘地线设计和改造,对于节能和减少接地环流线路损耗以及线路融冰都是必要的。文章结合高压架空线路运行状态在线监测技术,从绝缘OPGW光缆和架空地线的感应电中抽能,给塔上在线监测设备供电,取代目前塔上不可靠的太阳能供电方式,创新设计一种架空线路节能降耗的自供电技术。

The design and modification of OPGW according to the requirements of insulated ground wire is necessary for reducing grounding loop line losses and line ice melting. Considering the power supply requirement for operation condition of high voltage overhead lines, this paper discussed the induction to take power technology through OPGW cables. The energy can be extracted from induction power to supply on-line monitoring equipment on the tower, this can replace the current unreliable solar power supply mode and provide a power self-supply solution tbr operation condition monitoring of overhead lines.
