From current time to the time for getting first current data after restoring.
Specifically, the 7th above-mentioned preset time period can be 15 days.
In a kind of optional scheme, after judgement distribution line failure tripping, line tripping duration can also be calculated,
Specifically, it if reclosing success, trips duration=reclosure time-trip time；If reclosing is unsuccessful, trip
Duration=trip time recovery time-, wherein recovery time can click several rule-likes and be calculated：
The first rule：After the current value at a nearest time point restores normal after tripping, it can will adopt
Collect the time of the corresponding signal of " combined floodgate " state of a nearest switchgear as recovery time；
Second of rule：First electric current recovery normal time in 15 days after tripping is calculated, it can will be at this
The time of the corresponding signal of " combined floodgate " state of a collected nearest switchgear is as recovery time before time；
The third rule：If not the time of the corresponding signal of " combined floodgate " state of switchgear, can will send out
Collected first current value restores the normal time as recovery time after raw tripping.
Optionally, in the above embodiment of the present invention, step S158 is obtained according to the difference of recovery time and trip time
The corresponding tripping duration of distribution line, including：
Step S1582, judges whether recovery time is less than preset value.

Step S1584, if it is determined that recovery time is less than or equal to preset value, then obtains reclosure time and trip time
Difference obtains tripping duration.
Step S1586, if it is determined that recovery time is more than preset value, then obtains the difference of recovery time and trip time,
Obtain tripping duration.
In a kind of optional scheme, if reclosing is unsuccessful, and the recovery time being calculated is less than 30 seconds, then may be used
With direct determining tripping duration=reclosure time-trip time；If reclosing is unsuccessful and recovery time for being calculated
It is longer, then it can determine tripping duration=trip time recovery time-.
Fig. 3 is a kind of flow chart of the failure analysis method of optional distribution line according to the ... of the embodiment of the present invention, below
A kind of preferred embodiment of the present invention is described in detail in conjunction with Fig. 3, as shown in figure 3, this method may include：Acquire remote signalling
Signal (including switch division and protection act), judges whether switch is " dividing ", if it is, it is determined as that generic failure trips,
And further judge whether reclosing succeeds, if it succeeds, being determined as that reclosing success trips, and calculate generic failure tripping
Duration；If it fails, being then determined as the unsuccessful tripping of reclosing, and calculate generic failure tripping duration.Determining general event
After barrier tripping, further it can judge that transmission test trips by judging whether to meet either condition：Preceding 2 electric currents are sentenced
Disconnected (whether the current value of 2 points is both less than threshold values i.e. before interpretation), central point electric current judges (i.e. by the current value in preceding 2 points
More than point centered on the point of threshold values, and judge whether the current value of former and later two points of central point is both less than threshold values) and whether
There are repair tickets, when judging to meet either condition, are determined as that transmission test trips.Judging that transmission test trips it
Afterwards, it can be determined that switched in 5 seconds whether division (judge to switch in 5 seconds and whether close a floodgate, and end-state be "on" position), such as
Fruit meets, then is determined as that trial line charging trips, and calculates trial line charging tripping duration, if conditions are not met, then calculating transmission test tripping
Duration；Furthermore it is possible to judge that electric current is always less than threshold values 1A in first 2 days, and the previous day is all "on" position, if it is satisfied, then
It is determined as that extension wire trips, and calculates extension wire tripping duration, if conditions are not met, then calculates transmission test tripping duration.
Specifically, if reclosing success, trip duration=reclosure time-tripping time of origin；If reclosing is not
Success, then calculate recovery time first, if recovery time is less than 30 seconds, the duration=reclosure time that trips-tripping occurs
Time, otherwise, trip duration=recovery time-tripping time of origin, wherein recovery time can be nearest after tripping
After the electric current at one time point restores, the time that a nearest switch closes, and can be before first electric current restores in 15 days,
A nearest switch closes the time, first electric current recovery time is can also be, if recovery time.
Through the above scheme, by the way that distribution line failure tripping is divided into generic failure tripping, transmission test tripping, tries to send
Electric tripping and extension wire four classes of tripping, and pass through the switch remote signals associated by distribution line, protection act remote signalling letter
Number and circuit telemetering of current data calculated and make tripping type comprehensive judgement, in order to be jumped to distribution network line
Lock situation is controlled in time, can targetedly assist carrying out power distribution network production maintenance work, to further increase power distribution network
Circuit reliability.And require, when calculating, have occupying system resources few, it is low to CPU and request memory, and support it is automatic and
The characteristics of manual calculations.
