Abstract: As the demand for power supply from enterprises and residential users increases, uninterrupted power distribution operations have gradually replaced traditional planned power outages as the main hazard method for repairing network line equipment. Using the bypass operation method to replace or install switches, drop fuses and other equipment under load is a routine and complex operation in the distribution network without power outages. All grassroots units of power grid enterprises carry out extensive tasks. This article analyzes the abnormal diversion problems of the bypass system found in actual on-site operations, and puts forward the issues that need to be paid attention to in such operations and the measures that should be taken to ensure the safe development of adjacent road operations in the community.
