Experimental Research On New Circuit Breaker Based On True Type Test Platform Of 10kV Distribution Network

At present, ground faults are a hot research topic at home and abroad. As many scientific research institutions and manufacturers continue to deepen single-phase ground faults, they have proposed a new type of environmentally friendly primary and secondary fusion pole-mounted circuit breaker ZW68. However, the manufacturer’ s products vary from good to bad, so the 10kV distribution network true platform is used to screen the quality of distribution network products. At the same time, single-phase grounding fault tests with different transition resistances and intermittent are grounding are carried out, verifying the new co-box type one and two times Integrated circuit breaker ZW68's ability to handle faults. Finally, through testing multiple new type common box type primary and secondary fusion pole-mounted circuit breakers ZW68, we put forward practical suggestions for the manufacturer's new products.
