1. CN101909930 - Overhead line tension balancer, and device adapted to prevent lubricating oil from scattering and used for the overhead line tension balancer

An overhead line tension balancer has a water drain structure and can prevent lubricating oil in the tension balancer from scattering to the outside. An overhead line tension balancer (100) for supporting a spanned overhead line while applying tension thereto, wherein rainwater collecting inside the overhead line tension balancer is collected from a collecting pipe connecting section (209) into a collecting tank (211) through a collecting pipe (207). The oil content of grease applied to the inside of the overhead line tension balancer (100) is prevented from scattering to the outside even if the oil content is fluidized together with the rainwater.

本发明提供一种采用除水构造且能够抑制起因于内部的润滑油的油成分向外部飞散的架空线用张力平衡器。在将张力施加于架设的架空线并进行支撑的架空线用张力平衡器(100)中，将积存在内部的雨水从收集管连接部(209)经由收集管(207)，收集到回收箱(211)。通过这样，即使涂布在架空线用张力平衡器(100)内的滑脂的油成分与雨水一起变得流动化，也能够防止向外部飞散的事态。
