Abstract: 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.
