Abstract
本实用新型涉及一种10kV配电线路内置避雷器绝缘子。其结构为，耐张杆中间相安装内置避雷器绝缘子，避雷器的底部安装脱离器。本实用新型使10kv配电线路运行效果理想，雷击断线事故减少，结构简单，成本低，实用性强，适合推广应用。
The utility model relates to an insulator with a built-in lightning arrester for a 10kV power distribution line. Its structure is that the middle phase of the tension bar is equipped with a built-in lightning arrester insulator, and the bottom of the lightning arrester is equipped with a disconnector. The utility model makes the operation effect of the 10kv power distribution line ideal, reduces the accidents of disconnection due to lightning strikes, has simple structure, low cost and strong practicability, and is suitable for popularization and application.
Description
Technical field
The utility model relates to a kind of insulator, relates in particular to the built-in lightening arrestor insulator of a kind of 10kV distribution line, belongs to the Electric Application field.
Background technology
In recent years, built-in lightening arrestor insulator has been installed by electric company on many 10kV distribution lines of the about 400km of length, but operational effect is unsatisfactory.According to statistics, the lightning-caused breaking accident that took place in 2011 rises 120% than rate of failure in 2010, causes certain economic loss and social harmful effect to company.
Summary of the invention
The utility model provides a kind of 10kV distribution line built-in lightening arrestor insulator to the problem that exists in the above-mentioned prior art, and having solved the 10kv distribution line, that built-in lightening arrestor insulator operational effect is installed is undesirable, the problem that the lightning-caused breaking accident is many.
The technical scheme of the utility model is following:
Built-in lightening arrestor insulator is installed in the middle of the strain insulator bar mutually, and disconnector is installed in the bottom of lightning arrester.
The utility model has the advantages of:
10kv distribution line operational effect is desirable, and the lightning-caused breaking accident reduces, and simple in structure, cost is low, and is practical, is fit to apply.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure, 1, insulator, 2, disconnector.
Embodiment
Embodiment
The distribution line that built-in lightening arrestor insulator is installed is strengthened patrolling and examining, simultaneously this kind lightning arrester is carried out electrical test one by one.To easy generation lightning overvoltage and the circuit of built-in lightening arrestor insulator has been installed, installing meets the earth connection that rules require.Analyze built-in lightening arrestor insulator and pure insulator theoretically and carry out electric property relatively, prove the reasonability of " insulation coordination ".
Be provided with mutually the built-in lightening arrestor insulator except in the middle of the strain insulator bar, all the other positions all are provided with pure insulator.The built-in lightening arrestor insulator that phase is installed in the middle of the strain insulator bar need not the insulation layer structure of acupuncture insulated conductor.In built-in lightning arrester bottom disconnector is installed.Installation meets the earth connection that rules require.
