Description
Technical field
The invention belongs to electric power project engineering fields more particularly to a kind of leakage conductor to install reconnaissance method.
Background technique
Overhead transmission line conveying distance is remote, and active channel is wide, is typically distributed across city, rural open field or mountain area.
Consider from safety and insulation angle, iron tower of power transmission line height is generally all in 20m or more, and most transmission lines of electricity are all fortune
Row is in exposed environments, and line steel tower is often neighbouring highest works, and in area with more lightning activities domain, line steel tower is hit general by thunder and lightning
Rate is larger.And after transmission line of electricity is struck by lightning, it is likely to result in power-off event, seriously affects the production and living of resident.For this purpose, power supply
Department usually selects the lightning protection auxiliary equipment such as zinc oxide surge arresters on iron tower of power transmission line to prevent transmission line lightning stroke.However, working as
The installation reconnaissance of preceding leakage conductor has no unified Regulations can for reference, and reconnaissance relies primarily on teams and groups technician, and people
Member's quality is different to lead to problems such as leakage conductor installation reconnaissance in the presence of random larger.
Summary of the invention
The technical problem to be solved in the present invention: in view of the above problems in the prior art, providing one kind not only can be improved choosing
Point mass, reduce because peopleware it is different caused by it is random, the route of the labor intensity of operating personnel can also be substantially reduced
Arrester installs reconnaissance method.
In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention are as follows:
A kind of leakage conductor installation reconnaissance method, implementation steps include:
1) it determines the shaft tower coordinate of route, and the shaft tower coordinate of route is imported into map；
2) installation point to be selected is determined on map；
3) it is directed to each installation point to be selected, obtains the assessed value of corresponding each damage to crops caused by thunder factor, each damage to crops caused by thunder respectively
The factor include span L1, history lightning strike spot L2, cross a river or mountain valley L3, Some Mining Districts L4, side slope L5, height difference L6, height above sea level L7, dodge
Density L8, L9 in 2 kilometers of transforming plant lead-in, and summed to obtain weight factor and K according to the value of each damage to crops caused by thunder factor；
4) select installation point to be selected that reconnaissance is installed as final arrester according to weight factor and K.
The detailed step of step 4) includes:
S1) whether up to standard as preliminary sieve according to the assessed value for the damage to crops caused by thunder factor specified in the assessed value of each damage to crops caused by thunder factor
Condition is selected to carry out preliminary screening；
S2) select installation point to be selected as final arrester installation choosing according to the result of preliminary screening, weight factor and K
Point.
Preferably, step S2) detailed step include: the installation to be selected for filtering out weight factor and K and being greater than preset threshold
Point selects at least one installation point to be selected to install reconnaissance as final arrester from the installation point to be selected for meeting target.Or
Person preferably, step S2) detailed step include: to be ranked up according to weight factor and K to all installation points to be selected, from row
Select at least one weight factor and the installation point to be selected of K optimum orientation that reconnaissance is installed as final arrester in sequence result.
Leakage conductor of the present invention installation reconnaissance method have an advantage that the present invention in the shaft tower coordinate for determining route,
And the shaft tower coordinate of route is imported into map, determine that installation point to be selected obtains respectively for each installation point to be selected on map
The assessed value of corresponding each damage to crops caused by thunder factor, each damage to crops caused by thunder factor include span L1, history lightning strike spot L2, cross a river or mountain valley L3,
Some Mining Districts L4, side slope L5, height difference L6, height above sea level L7, CG lightning density L8, L9 in 2 kilometers of transforming plant lead-in, and according to each damage to crops caused by thunder
The value of the factor is summed to obtain weight factor and K, finally selects installation point to be selected to keep away as final according to weight factor and K
Thunder device installs reconnaissance, not only can be improved reconnaissance quality, reduce because peopleware it is different caused by it is random, can also drop significantly
The labor intensity of low operating personnel.
Detailed description of the invention
Fig. 1 is the basic procedure schematic diagram of the embodiment of the present invention one.
