35 kV断路器弹簧钢的夹杂物微观形态分析
The Microscopic Morphological Analysis of 35kV Circuit Breaker's Spring Steel Inclusions
摘要
Abstract
This article studies the relaxation phenomena of 35kV circuit breaker spring. Through spectral analysis, microstructure and inclusion test rating of spring, combined SEM and micro energy spectrum and morphology analysis of inclusion composition, found that the main reason of this relaxation phenomena is unqualified material.关键词
