Abstract

The 400kV Mintia-Sibiu OHL was build in 1971-1972. In 2011-2013 National Transmission Company (CN Transelectrica SA) performed a refurbishment project for the OHL elements. A part of this large project is executed in LW technology by the maintenance subsidiary of Transelectrica (SC Smart SA). The live working part of project consist of: replacement of suspension insulation strings, replacement of insulation chain elements, replacement of dampers, replacement of vibration dampers, Installation of armour-rods together with suspension clamps, painting, Installation of aerial plates on towers, replacement of damaged tower elements. The work was done using some new methods for access on the conductors, including the aerial insulating platform class A. When a project starts we should consider all the ways to complete the works. Considering present technologies used in Romania some works needs deenergization of the line. For other parts of the project Live Working is mandatory, in order to maintain the system's stability. At the end of the project an economical analysis is done. Was it efficient to use Live Maintenance technologies?

400kV Mintia-Sibiu OHL建于1971-1972年。2011-2013年，国家输电公司(CN transelecica SA)对OHL元件进行了翻新项目。这个大型项目的一部分由transselecica (SC Smart SA)的维护子公司执行LW技术。本工程带电工作部分包括:更换悬架绝缘串、更换绝缘链元件、更换阻尼器、更换减振器、安装护杆及悬挂夹、喷漆、安装塔架架空板、更换损坏的塔架元件。这项工作采用了一些新的方法来接近导线，包括a级架空绝缘平台。当一个项目开始时，我们应该考虑所有的方法来完成工作。考虑到罗马尼亚目前使用的技术，一些工程需要对线路进行断电。对于项目的其他部分，Live Working是强制性的，以保持系统的稳定性。在项目的最后进行了经济分析。使用实时维护技术是否有效?
