为了改善马尔康至草地四县、马尔康至汶川五县以及马尔康至成都等电路的紧张状况;提高明线线路的复用指数,在马尔康以东六十多公里,上述电路的汇集咽喉口——马塘设立一个增音站的技术方案是可取的。这样可在现有的线路上再增开六套12路载波端机,从而大大提高了明线线路的复用率。然而,要在马塘设立增音站,首先遇到的问题是电源不好解放,该地人烟稀少,地处高寒。只有一个生产队,仅有的一个小电站,电压又不稳定,且经常断电,难以保证通信的需要。根据我区太阳能资源丰富这一得天独厚的自然条件,以及我们在两河,可尔因增音机应用太阳能电池的成功经验。经过可行性技术论证,在马塘增音站应用太阳能电池供电,实行无人值守,这在经济上是划算的,技术上是可行的。
In order to improve the tensions in the Malkon-Grassland four counties, the Malkan-Wenchuan five counties, and the Malkan-Chengdu circuit; to increase the reuse index of the open-air line, more than 60 kilometers east of Malkon, the collection of the above-mentioned circuits - Matang It is advisable to set up a technical scheme for a sound reinforcement station. In this way, six sets of 12-channel carrier terminals can be added to the existing lines, thereby greatly improving the reuse rate of the open-circuit lines. However, the first problem encountered when setting up a sound-increasing station in Matang is that the power supply is not liberated. The land is sparsely populated and it is located in the cold. There is only one production team and only one small power station. The voltage is unstable, and power is often cut off, which makes it difficult to ensure the need for communication. According to the unique natural conditions of our district’s rich solar energy resources, and our successful experience in the application of solar cells to the Keeling sounders in Lianghe. After feasibility technical demonstration, the application of solar battery power supply at the Matang Shengmian station is unattended, which is economically cost-effective and technically feasible.
