single-roll breaker

Practically, most distribution feeders are open ring systems with single circuit breaker configuration.

实际上, 大多数配电馈线开放环系统与单断路器配置.

Study on Protection of Single Breaker in Lingbao BTB Project

灵宝背靠背工程单断路器保护研究

Single circuit breaker configuration is more economical because fewer circuit breakers are used.

单断路器配置是更经济,因为更少断路器使用.

When the reconfiguration of single loop networks accords with the economic current distribution, the switch, through which passes the smallest current and no branch over current, is the branch breaker.

在单环网的重构中按电流经济分布时，将流过电流绝对值最小的且没有支路电流过载的开关作为断开开关。

Single-phase controllers utilize a pole, common trip circuit breaker with 10,000 amp symmetrical interrupting capacity rating.

单相 控制装置采用两极 、 普通行程断路器,额定对称中断能力为10,000安培.
