New Distribution Network


Built-in pillar type lightning protection and pressure limiting device


 


Technical Features:


Adopting an integrated structure, the insulator and the arrester are integrally molded to solve the problem that the insulator and the arrester need to be installed separately, and there is no need to strip or puncture during installation, eliminating the impact of the construction process on the mechanical performance and sealing performance of the insulated wire;When the lightning amplitude is too high, after the arrester breaks down,the insulator still has the function of supporting the wire, and the overhead line of the distribution network can still operate normally, which can reduce the line problems caused by the failure of the lightning protection device itself.


 


A lightning strike indication method based on the temperature rise discoloration effect is proposed. A special irreversible color-changing paint is sprayed on the surface of the equalizing ring. When the arrester is broken down, the power frequency arc is applied to the equalizing ring, and the equalizing ring changes from orange to orange. The color is black, which solves the problem that the identification of the lightning protection device is not obvious and the line inspector is difficult to find the fault.


 


The discharge electrode of the device adopts a built-in ring electrode, which has reliable operation, fixed gap distance, stable discharge voltage, and does not require on-site manual adjustment. This solves the problem of current lightning protection devices limited by installation technology and effectively improves the lightning protection effect of the device.


 


The new type of built-in column lightning protection and voltage limiting device for distribution network proposes to install a simple lightning discharge counter in areas where lightning strikes frequently occur, which can record the number of lightning strikes in real time, effectively improve the monitoring level of overhead lines in the distribution network, and also provide life management for lightning protection devices analyze data.
