Method for reducing interruption times of customers during overhaul operation

The invention discloses a method for reducing interruption times of customers during an overhaul operation. The method includes the steps of: determining the area where a line to be maintained is, wherein one end of the line to be maintained is a first line, and the other end is a second line; checking phase sequences at two sides of an interconnection switch of the first line and the second line; under the condition that the phase sequences at the two sides of the interconnection switch is correct, performing loop closing operation on the first line and the second line according to a blending instruction; and in a pre-set time, performing looping-off operation on the first line and the second line. Therefore, during this process, there is no need for power cut in the area where the line to be maintained is, and the area is still in a normal operation under the loop closing power supply condition. Compared with a conventional method according to which power cut is conducted at first, the method has the advantages that interruption times of the customers during the overhaul operation are reduced, and thus the power supply satisfaction rate of the customers is improved.
