Description
Technical field
The utility model relates to electrical equipment technical fields, supervise more particularly, to a kind of differentiation branch line operation data
Survey device.
Background technique
Currently, distribution operation maintenance personnel can implement platform area low-voltage load monitoring work by metering automation system.In Tai Qu
It installs metering CT on the bus of low-tension distribution box additional and acquires current signal, by measuring terminal voltage, electric current, active and reactive etc.
Data are sent to backstage, consult in metering automation system for user.
However, this hardware configuration can only data on picking platform area bus, system can only monitor the total load in platform area,
The load condition of each branch switch back segment low-pressure line-outgoing in distribution box can not be monitored.
In the routine work of distribution O&M class, the loading condition of each road branch line in platform area influences maintenance work most important.
If having no idea to grasp the operation data of each road branch line in platform area, just have no idea to carry out load Analysis to each road outlet, whenever
The tripping of low pressure branch switch excess load occurs for peak times of power consumption summer, many platform areas.
According to statistics, Tan Zhou branch office is during 2012-2017, and platform area low tension switch trips in power-off event, and branch line is opened
It closes tripping and accounts for 90%, illustrate the reason of causing low-voltage load unplanned property in platform area to have a power failure, be primarily due to bear each road branch line
Lotus monitoring lacks effective measures, without carrying out load cutover work in time, branch switch is caused to trip.When platform area low-voltage circuit is sent out
Raw single-line ground (electric leakage) does not use residual current protecting due to being all made of air-break circuit-breaker in the low-tension distribution box of middle mountain office
Breaker (leakage switch), since the action value of protection is not achieved in electric current, so switch is failure to actuate, it can not automatism isolation.Due to
Each branch line in platform area has no idea to monitor load current, also just has no idea to measure residual current, operation maintenance personnel reaches existing
Field also has no idea immediately to judge to occur branch's line position of ground fault, can only be by trying drag switch, until ground fault disappears
It loses, then the branch line of non-faulting again power transmission, first-aid repair efficiency has to be hoisted, and the user that also resulting in originally can not have a power failure stops in short-term
Electricity.
In the prior art lack platform distinguish branch line load monitoring means, be easy to cause certain all the way outlet excess load not by and
Shi Faxian causes non-plan repair fault outage, brings loss for enterprise and user, when low pressure single-line ground event occurs for platform area
Barrier, repair personnel scene are difficult to quickly judge hair.
