With the global emphasis on sustainable development and environmental protection, the proposal of the "dual carbon goals", namely carbon peak and carbon neutrality goals, has brought unprecedented development opportunities to the new energy field. As an important component of new energy,  PV power generation is rapidly entering a new stage of large-scale, market-oriented, high-proportion and high-quality development. In this context, the stability and safety of the power system are particularly important. As a key device in the power system, the performance of the ACB directly affects the reliability of the entire system.

    ACB play a vital role in PV power generation systems. They need to maintain stable operation under various extreme conditions to ensure continuous power supply and safety protection of the system. Powder metallurgy contact materials are ideal for manufacturing high-performance ACB due to their unique properties. These materials can adapt to super large currents, with excellent resistance to arc erosion and anti-welding ability, allowing them to maintain excellent performance under high loads and extreme temperatures.

    In order to meet the high performance requirements of PV power generation systems for ACB, the following are several recommended powder metallurgy contact materials:

    ① AgWC40: This material combines the high conductivity of Ag and the wear resistance of WC, giving it excellent electrical contact performance and arc erosion resistance in high current environments.

    ② AgNi30/AgNi25C2: AgNi is widely used as contact material due to its good electrical conductivity and thermal conductivity, making it suitable for use in high-load circuit breakers.

    ③ AgW50: AgW is known for its extremely high hardness and excellent wear resistance. The sintering process further increases the density and uniformity of the material, making it ideal for withstanding high currents and extreme operating conditions.

    The application of powder metallurgy contact materials not only improves the performance of ACB, but also provides a strong guarantee for the stable operation of PV power generation  systems. With the continuous advancement of technology and the development of new materials, powder metallurgy materials will play a more important role in the field of new energy in the future, making greater contributions to achieving the "dual carbon goals" and building new power systems.
