Abstract
The invention relates to a lightning protection method of lightning arresters on a 10-KV distribution line. The lightning protection method comprises steps as follows: avoiding overlapping front guide waves and reflection waves of two groups of adjacent lightning arresters on an insulator at the same time when suffering from the lightning stroke; installing a group of the lightning arresters on every even base rod; cancelling the installation of the lightning arrester on a lower layer of a double-circuit line arranged up and down; and not installing the lightning arrester for the area shielded by high buildings. The invented method does not influence the normal and safe running of the distribution line. The engineering construction is simple and the maintenance is convenient. The construction cost, the construction, the maintenance and the lightning protection effect are taken into comprehensive consideration to achieve the most economical lightning protection effect.
Description
Technical field
The present invention relates to a kind of lightening arresting method, relate in particular to a kind of lightening arresting method of 10KV distribution line lightning arrester, belong to the Electric Application field.
Background technology
10kV distribution line the most effectively lightening arresting method is that lightning arrester is installed, and obviously is one sided but near insulator on every bar or the electric equipment lightning arrester is installed all, and is also uneconomical.Factor such as project cost, construction, maintenance and lightning protection effect are taken all factors into consideration, and where, what lightning arresters are installed, reaching most economical lightning protection effect is to need the urgent problem that solves at present.
Summary of the invention
The present invention is directed to the problem that exists in the above-mentioned prior art,, through lightning protection effect relatively, a kind of lightening arresting method of 10KV distribution line lightning arrester is provided according to thunder and lightning statistics and tripping operation number of times.Solved the problem that factor such as project cost, construction, maintenance and lightning protection effect in the prior art can not the coordinating and unifyings.
Technical scheme of the present invention is following:
When avoiding being struck by lightning two groups of adjacent lightning arresters before draw ripple and reflected wave is superimposed on the insulator at one time; Every at a distance from even number base bar, one group of lightning arrester is installed;
For the double-circuit line that levels is arranged, its lower floor's cancellation lightning arrester is installed;
High-rise is blocked the area, lightning arrester is not installed.
Advantageous effect of the present invention is following:
1, do not influence the normal safe operation of distribution line.
2, engineering construction is simple, easy to maintenance.
3, factors such as project cost, construction, maintenance and lightning protection effect are taken all factors into consideration, reached most economical lightning protection effect.

Through statistics and analysis distribution line switch trip, line-to-ground, disconnection fault, disconnector damages and the counter action frequency, is combining data that lightning location system is surveyed, and takes following concrete measure:
When avoiding being struck by lightning two groups of adjacent lightning arresters before draw ripple and reflected wave is superimposed on the insulator at one time; Every at a distance from the basic bar of even number (2 or 4 or 6), according to actual concrete condition, one group of lightning arrester is installed;
For the double-circuit line that levels is arranged, its lower floor's cancellation lightning arrester is installed;
High-rise is blocked the area, lightning arrester is not installed.
