Feasibility Analysis Of Chemical Resistance Reduction For Surge Arresters

The 400 kv lightning arrester device plays a crucial role in the power system, and its performance directly affects the system's stability. Chemical resistance reduction involves reducing the surface or internal resistance of 66 kv lightning arrester through material treatment, thereby improving its transient response characteristics.

The principle of chemical resistance reduction

Chemical resistance reduction achieves resistance control by forming a conductive thin film on the surface of 66kv surge arrester material or adjusting the conductivity of the internal composite material. Resistance-reducing materials typically include oxide conductors or conductive polymers, which can alter charge migration paths at the microscopic level.

• Surface treatment: Apply a chemical coating to the 69 kv lightning arrester casing to form a uniform conductive layer.

• Internal Modification: Introducing conductive fillers into zinc oxide or other core materials to optimize current distribution.

• Durability Considerations: Material stability significantly affects long-term performance and requires experimental data verification.

These methods can theoretically adjust the electrical characteristics of surge arresters, but their practical application still needs to be considered in conjunction with environmental conditions and power grid design requirements.

Applicable conditions for chemical resistance reduction

9kv 5ka lightning arrester can be chemically resisted, but the ambient humidity, pollution level, and long-term voltage withstand capability must be assessed. In high-humidity and high-pollution areas, the surface of 9kv lightning arrester is prone to corona discharge and leakage. Chemical resistance reduction can improve the conductivity to some extent.
