旁路作业技术在配电网工程中的研究与应用

配电不停电作业技术是提高供电可靠性的重要手段,已不断受到国内供电企业重视。其中的旁路作业技术作为不停电解决配电网大型检修和改造工程的有效方式,一直被业内归类为配电不停电作业技术中最复杂的作业项目。按照传统作业方式,旁路作业的开展将依托柔性电缆和旁路开关等设备形成较为复杂的旁路系统,以实现负荷转移,作业过程牵涉多班组和多专业配合,准备工作多,需投入较多的人力、物力,且现场安全风险管控难度较大。对传统旁路作业现场组织管理流程进行总结,提出了一种多班组、多专业作业现场组织管理模式和一种新的旁路作业技术。经多次现场实践,证明该方法在配电网检修和改造中是有效且实用的。

Research and Application about Usage of Bypass Working in Distribution Network Reconstruction

Live working technology is an important means to improve the reliability of power supply, which has been constantly attached importance by the domestic power supply enterprises. As an effective way to solve the large-scale maintenance and reconstruction project of distribution network, the bypass working technology is classified as the most complex live working. According to the traditional methods, bypass working should rely on flexible cables, bypass switches and other special equipments to form a complex bypass system to achieve load transfer. The operation process involves multiple professional departments, and requires more worker and equipment.The traditional bypass working process is summarized. A multi-departments, multi-fields organization and management idea is proposed, and a new bypass working technology is put forward. It is proved that the proposed method is effective and practical in the maintenance and reconstruction of distribution network.
