| 智能断路器选型 Selection of intelligent circuit breaker 智能型万能式断路器用作电气设备或线路保护时，用户选型时主要有以下4点考虑： When the intelligent universal circuit breaker is used as electrical equipment or line protection, the following four points should be considered when selecting the type of intelligent universal circuit breaker: （1）选用断路器的额定电流大于或等于线路或电气设备的额定电流； (1) The rated current of the selected circuit breaker is greater than or equal to the rated current of the line or electrical equipment; （2）选用断路器的额定短路分断能力（电流）大于或等于线路的预期（最大）短路电流； (2) The rated short-circuit breaking capacity (current) of the selected circuit breaker is greater than or equal to the expected (maximum) short-circuit current of the line; （3）选用断路器的保护功能相对完善全面，能满足其工作场合的要求； (3) The protection function of the circuit breaker is relatively perfect and comprehensive, which can meet the requirements of its working place; （4）选用断路器的外形尺寸相对较小，节省空间， 智能断路器便于在同一柜内可安装多台断路器。 (4) The size of the circuit breaker is relatively small, which saves space. The intelligent circuit breaker is easy to install multiple circuit breakers in the same cabinet. |
