摘要： PROBLEM TO BE SOLVED: To provide a power supply feeder for construction in which switching construction of an existing power supply feeder and an existing coaxial cable can be executed in an uninterruptive wave manner in maintenance work of a transmission path for a cable television. SOLUTION: The power supply feeder for the construction is composed of a rectifier (12) for rectifying AC fed from an external power supply to DC, an inverter (13) for converting the rectified DC to the AC matched with the phase of the AC flowing in a coaxial cable (5) for the CATV and for outputting it, a transformer (14) for outputting the voltage of the inverter output by matching it with the voltage of the coaxial cable (5), and a control unit (CON) for controlling the inverter(13) so that the phase of the inverter output is matched with the phase of the AC flowing in the coaxial cable (5) by detecting the phase of the AC of the external power supply and the phase of the AC flowing in the coaxial cable (5).

摘要： PROBLEM TO BE SOLVED: To provide a method of replacing an aerial line between electric poles, without an old line or a new line getting hung down between the electric poles when replacing to a new line, capable of performing a replacement work without any obstacle even at a place crossing over a heavy traffic road or over a private land, furthermore with excellent safety and workability, and to provide a replacement tool enabling the method.SOLUTION: A cylindrical cover member 10 made of plastic is sequentially mounted on an old line 16 to be replaced from a pole 24 on a sending side toward a pole 26 on a receiving side. As a replacement from an old line 16 to a new line 30 is done through the inside of the cover member 10, the new line 30 can be newly laid at the same position as the old line 16, without getting an aerial line or the like hung down between the electric poles 24 and 26. Furthermore, the cover member 10 is made of light plastic, which makes it possible to lift it rather easily up to the electric pole 24 so as to contribute to the safety of a replacement work.
摘要翻译：要解决的问题：提供一种替换电线之间的架空电线的方法，在更换新线路之前，不需要在电线杆之间旧线或新线路挂起，能够进行更换工作而无需更换任何障碍物，即使在交通繁忙的交通道路或私人土地上的地方，此外还具有良好的安全性和可操作性，并提供使该方法更换的工具。解决方案：由塑料制成的圆柱形盖构件10依次安装在旧线16上，以从发送侧的极24朝向接收侧的极26更换。作为从原线16到新线30的替代，通过盖构件10的内部完成，新线30可以重新铺设在与旧线16相同的位置，而不会得到架空线等悬挂在电杆24和26之间。此外，盖构件10由轻塑料制成，这使得可以更容易地将其提升到电杆24，从而有助于更换作业的安全性。版权所有（C）2013，JPO＆INPIT
