Abstract

The invention relates to the technical field of electric power system maintenance, in particular to a malfunction early warning method and system for a power distribution room of power-guaranteed users, consisting of a current measuring device, a voltage measuring device, a switch state detecting device, a wireless communication device,a display device, an alarm device and a microprocessor. The malfunction early warning method and system for a power distribution room of power-guaranteed users are characterized in that the current measuring device, the voltage measuring device, and the switch state detecting device are all assigned an identification ID; the current measuring device and the voltage measuring device are arranged on a measuring point of a power distribution room of power-guaranteed users; the measuring point is positioned at a starting point of a power distribution branch of power-guaranteed users and a connection point of power distribution equipment; the switch state detecting device is arranged on a distribution line switch of power-guaranteed users, and the wireless communication device is arranged in the power distribution room of power-guaranteed users. The malfunction early warning method and system for a power distribution room of power-guaranteed users have advantages of discovering faults of indoor power distribution lines and equipment and warning power-guaranteed users in time, handling and repairing malfunction,and speeding up the recovery of power for users.

Description

technical field [0001] The invention relates to the technical field of power system maintenance, in particular to a fault warning method and system for a power distribution room of a power-guaranteed user. Background technique [0002] The power consumption of important users is the focus of power supply enterprises. Although there are not many important users, they occupy an important position in the local society, politics, and economy. Interruption of power supply may cause greater political impact and greater economic impact. losses, and even serious disruption of social public order. At present, the focus of the task of ensuring power supply for important users is to ensure that the distribution network equipment is free from failure, while ignoring the failure of the user's own electrical equipment. When a short-circuit fault occurs in one of the user's electrical equipment, even if the distribution network is not faulty, it will also cause the user to cut off the pow...
