1. Do a good job in lightning protection management
In the design and planning of power distribution lines, the local natural climate and the surrounding environment of the power distribution lines should be fully considered, and lightning arresters and insulators should be renewed reasonably. For example, for areas with open areas and frequent lightning accidents, it is necessary to increase the number of lightning protection facilities, and regularly carry out lightning arrester grounding resistance testing to improve the effectiveness and reliability of lightning protection facilities and ensure the normal operation of power distribution lines.
2. do a good job in equipment transformation
The transformation of power distribution equipment is usually to rationalize the lightning protection infrastructure of power distribution lines to improve the effectiveness of lightning protection facilities. For example, installing pillar insulators as much as possible can effectively improve the quality of insulators and enhance the insulation capacity of distribution lines; the original distribution line connectors can be changed and replaced by amp clamps, which will not affect the distribution lines; timely Replace the resistance that does not meet the requirements, and install advanced lightning arresters, such as oxidation arresters, to improve the lightning protection effect.
3. do a good job of protecting the electrode gap
Because the distribution line is usually affected by thunderstorms and exploded during actual operation, it is necessary to do a good job of protecting the electrode gap. During the construction of power distribution lines, metal ball electrodes are generally installed in parallel on both sides of the insulator string, so there is a protection gap, which is usually determined according to relevant experimental data. Generally, after the power distribution line is struck by lightning, the ground wire will often produce a certain overvoltage. If the gap discharge voltage is not greater than the discharge voltage on both sides of the insulator, the safety of the insulator can be effectively ensured.
4. strengthen the control circuit resistance
Strengthen the control of the line resistance, which can enhance the lightning protection safety of the distribution line. In the actual operation of the distribution line, reducing the resistance of the distribution line can effectively reduce the power consumption in the operation of the power line, and can also effectively improve the efficiency of the use of power resources. In order to reduce the resistance of the distribution line and strengthen the effective adjustment of the resistance, the current in the distribution line is introduced into the ground network, thereby reducing the impact of lightning on the line, and laying a good foundation for the improvement of the quality of the distribution line. Leading the lightning current into the ground grid can not only reduce the resistance, but also reduce the construction cost of the resistance, thereby improving the economic benefits of power enterprises. For the resistance control of distribution lines, the line resistance can be reduced according to the requirements of the distribution resistance, and resistance reduction equipment can be integrated and applied.
