On mechanical calculation of optical-fiber composite overhead ground wire

从理论上阐述了光纤复合架空地线在大气过电压情况下,如何满足规程规定的导地线距离的要求。介绍了光纤复合架空地线的架线形式,提出了实际工程中按耐张型悬挂方式的光纤复合架空地线应力的求解方法,并对弧垂观测档的选取进行了探讨。通过此方法计算在大气过电压情况下的弧垂曲线,能满足工程需要。

This paper theoretically expounds how optical-fiber composite overhead ground wire（OPGW） meets the conductor-to-ground-wire spacing requirement in relevant code at atmospheric over-voltage. With the description of the stringing forms of OPGW, the stress solving method of OPGW suspended in the strain form in practical engineering is presented, and selection of the sag observation span approached. The sag curve at atmospheric over-voltage calculated by this method can meet the needs of engineering.
