Description
Technical field
The present invention relates to a kind of distribute-electricity transformer district perception terminal device and methods, belong to smart grid, intelligent power technology neck
Domain.
Background technique
With the construction of strong smart grid, the reliability of China's power grid is continuously improved, and grid company itself takes power supply
The check requirements of business also improve year by year.China's residential electricity consumption speedup is exceedingly fast, and it is big, a that resident's platform area shows number of users again
The problems such as body electricity consumption behavior is complicated, fault location difficulty is big, electric network state level monitoring is low.
Currently, resident's platform area failure actively perceive level is low, troubleshooting time is long, the processing of resident's platform area's power-off fault
Technical level is also in the passive repairing stage, while there is also positioning to be not allowed, accident responsibility assert the problems such as horizontal low.
Passive repairing causes slow, repair call heavy workload of sending a telegram in reply.Intelligent electric meter is in client's power loss only to power-off event
It keeps a record, uniformly reports power failure and telegram in reply event after telegram in reply again, so company can not carry out repairing work in first time, it can only
Passive waiting user carries out repairing after dialing 95598 repair calls again, causes fault handling time substantially to extend, and same
A large amount of customer interrupteds in platform area can all dial repairing phone, cause unnecessary repair call processing workload.
It is low that failure automates position level.Low pressure resident is extremely complex for the topology of radio area, is related to 10kV inlet wire, transformation
Device, distribution box, feeder pillar, service cable, electricity box and user's internal circuit, are only difficult to effective position from the repair call of user
Fault point, difficult by artificial fault location and exclusion, the average time-consuming of malfunction elimination is up to 3 hours at present.

Power quality monitoring device is filled, it is insufficient to the power quality data acquisition of power grid end (resident's inlet wire) and analysis ability,
There are commonplace three-phase imbalance, load factor is high, voltage is low, idle excessive the problems such as, while lack of wisdom data are analyzed
System provides whole resolution.
The on-line monitoring for the quantity of states such as line impedance, user be separate also lacks effective technology means.Excessive contact resistance,
The problems such as broken neutral line, fuse aging, aging circuit, can all cause line impedance significant changes, and maintenance can be reduced in time
Via net loss prevents the major accidents such as electrical fire and personnel's electric shock；It is separate manual by ammeter installation personnel belonging to user
Record, once being difficult to discovery mistake after filing, Losses Analysis and three-phase imbalance control to company cause tired
It is puzzled.The quantity of states such as above-mentioned line impedance, user be separate also lack special equipment and system just to monitor and analyze.
To solve the above problems, having carried out the research and practice of a large amount of distribute-electricity transformer district monitoring terminals both at home and abroad, but majority is
Respective concern is solved, develops a large amount of independent terminal devices and system, but the incompleteness of detection technique, detection are calculated
