Study on the relief design for the fault current of polymer arrester

폴리머 피뢰기의 고장전류에 대한 방압 설계기술에 관한 연구

The chief advantage of polymer arrester. from design of pressure relief, anti-contamination, electrical failure was reduced by outdoor polymer housing. In the first for development of pressure relief design for polymer arrester, fault current and surge were studied through experiments of electrical. Designed the FRP inner tube and unit modules for pressure relief housing. Tested the performance of unit modules for pressure relief of polymer arrester, and the result was successful. The pressure relief of polymer arrester depend on design pattern of diamond shape and ellipse. Study on the pressure relief of FRP inner tube for outdoor polymer arrester. Designed and manufactured FRP inner tube of polymer arrester. Tested the fault current of polymer arrester per 10 kA, 10 cycle.
