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.
