摘要
介绍了一种高分断低压中小容量塑壳断路器。通过综合使用限流和灭弧措施,合理运用气吹、磁吹及气压反应机构,增大断路器开距,提高触头分断速度,达到了提高产品的分断能力和性价比的目的。本产品已实现批量生产,市场前景良好。
Introduction was made to a kind of moulded case circuit breaker with high-breaking low-voltage medium and small capacity.Through synthetic usage of current limiting and arc extinguishing measures,reasonably applying air-blowing,magnetic-blowing and air pressure reaction machine,raising circuit breaker opening distance and improving contacts breaking speed,the system reached the purpose of enhancing breaking capacity and good cost performance.The product has realized batch production with good market prospect.
