Description
Technical field
Determine method the invention belongs to the field of monitoring, more particularly to a kind of abort situation for low-voltage network.
Background technology
During annual summer peak meeting, residential electricity consumption load drastically abruptly increase, from 95598 Customer Service Centers (also known as electric power visitor
Family servicing call center system or 95598 customer service hotlines) the breakdown repair list for coming is transmitted through mainly with power distribution station low tension switch
Tripping operation, the molten knife fusing of feeder pillar, bar become based on the fusing of crane case stereotype, and the normal electricity consumption to low pressure resident causes very big shadow
Ring.When power supply reliability has turned into one critical services index of Utilities Electric Co., how quick fault point, eliminate failure,
Fast quick-recovery resident powers, and reduces resident's power off time, and this is related to Utilities Electric Co. to the promise of society and to value view
Practicing.
At this stage, low pressure resident breakdown repair basic procedure is as follows：
After family has a power failure, resident can contact residential property first, if trouble point does not belong to property and managed, resident will dial
95598 customer service hotlines are made a call to, 95598 Customer Service Centers can give each electric company according to address job order where residential households
Hold inquiry, hold the project to outsource team ask and can be dispatched to nearby according to the single specific address of repairing, after construction brigade makes house calls if it find that
Trouble point does not belong to it and is managed, and repairing can singly be replied to and hold inquiry by he, and propose to need scheduling assisted treatment, and holding inquiry again will repairing list
Control centre is given to, dispatcher arranges O＆M maintainer to go to in-situ processing failure again.
Be can be seen that in the case of some failures from above-mentioned breakdown repair flow, residential property, project to outsource team do not have
Solve resident to have a power failure this problem, the role of they simply eliminate the possible position in trouble point, if one can be developed
Set is directed to the failure fast positioning method or system of low-voltage network, the localization of faults within the most short time, it is possible to will be small
Area's property, the emergency repair time of these engineering noises of project to outsource team are omitted, and power network operation maintenance personnel goes directly to according to dispatcher's instruction
Trouble point handling failure, fast quick-recovery power transmission, improves rapidly power supply reliability.
