Description
Technical field
The present invention relates to power construction O&M field, particularly a kind of power circuit safe distance based on smart mobile phone measures appraisal procedure.
Background technology
Tradition electric energy is current energy source use form the most widely, is related to the productive life of huge numbers of families.Electric line carries the important task that electric energy conveying distributes.For ensureing the normal work of electric line, power circuit operating maintenance personnel are needed to carry out tour work to circuit, be divided into periodical inspection (generally monthly by the tour cycle, can number of times be increased if desired), special tour situations such as (at weather acute variation, disaster, circuit under) fully loaded and overloads, fault inspection (in order to find out line-to-ground, trip reason, finding out accident point).Make an inspection tour action and comprise inspection along thread environment with or without situation affecting line security etc., as the distance on the trees in guard plot, scissors crossing thing off-line road.Cut in the work of cutting superelevation trees, the human casualty accident caused because of safe distance deficiency happens occasionally.
At present, two kinds are mainly contained to circuit and the distance measurement method between ground, scissors crossing thing or trees:
(1) direct method of measurement: need to prepare insulation lining rope (or insulation survey high bar), step on bar instrument one secondary, personal security's instrument, ruler one or altimeter one.Throw to hang over insulation lining rope and wire directly measures wire over the ground or the distance of scissors crossing thing, during measurement, forbid to use tape measure, line chi (accompany tinsel person), and guarantee that surveyors' staff and charging equipment keep a safe distance.Also altimeter can be adopted directly to measure reading.
(2) indirect method of measurement: adopt the vertical range of transit survey wire over the ground or to scissors crossing thing.
There are the following problems for the method used at present:
1) required staff is many: at least need two people to coordinate;
2) outfit is many: insulation lining rope, insulation are surveyed high bar, stepped on bar instrument, personal security's instrument, ruler or altimeter, transit etc.;
3) required time and energy many: need to step on bar, throw and hang lining rope, or the transit using operation comparatively complicated;
4) function is more single: use altimeter or transit directly can only measure vertical range, cannot the distance of any two points in measurement space.The function of cutting and cutting trees security risk is not assessed yet;
5) required cost is high: comprise insulation lining rope, the high bar of insulation survey, step on the instrument costs such as bar instrument, personal security's instrument, ruler, altimeter, transit, and manually-operated cost;
6) the risk hidden danger existed is high: the particularly direct method of measurement, once underestimate safe distance, or touch because of carelessness in operating process, probably meet accident accident by mistake.
