line circuit-breaker的意思|示意

This paper presents a new on-line monitoring system for vacuum circuit breaker.

介绍了一种所研制的真空断路器新型智能在线监测系统。

Through analyzing the reclosing of circuit breaker in middle of line-transformer strings, the existing problems were figured out and the modification measures were put forward.

通过对线-变串中开关重合闸问题的分析，找出了存在的问题，提出了改进意见。

The paper analyse the requirements and implementation ways for protection of LV distribution line. Type selection and parameter setting of fuse and circuit-breaker are introduced.

系统地分析了低压配电线路保护的要求和实施方法，叙述了熔断器和断路器的选型，及其参数的整定；

With the structure as exterior impact the user's vision, also reflected the reliability of products, in line with the circuit breaker this kind of product characteristics.

用结构作为外观冲击用户的视觉，也体现了产品的可靠性，符合断路器这类产品的特点。

Protection against motor over - load usually adopt thermal relay, but protection against line over - load usually adopt long delay over- current release of circuit- breaker.

电动机过载保护通常采用继电器，而配电线路过载保护多采用断路器的长延时过电流脱扣器来完成。

That is, when the line failure, the relay circuit breaker tripping, the device auto-reclosing after a short time interval, so that a re-breaker.

即当线路出现故障，继电保护使断路器跳闸后，自动重合闸装置经短时间间隔后使断路器重新合上。
