Title (EN) CIRCUIT BREAKER
(FR) DISJONCTEUR
(ZH) 断路器
Abstract:
(EN) A circuit breaker, comprising: a primary protection circuit (100) connected to a protected circuit (300) in series; an auxiliary protection circuit (200) connected to the protected circuit (300) in series, the primary protection circuit (100) being connected to the auxiliary protection circuit (200) in parallel; a mechanical breaking means, which may break the primary protection circuit (100) when overcurrent occurs to the protected circuit (300); and a fusing means, which may be fused when the primary protection circuit (100) is broken to break the protected circuit (300).
(FR) L'invention concerne un disjoncteur comprenant : un circuit de protection primaire (100) branché en série à un circuit protégé (300) ; un circuit de protection auxiliaire (200) branché en série au circuit protégé (300), le circuit de protection primaire (100) étant branché en parallèle au circuit de protection auxiliaire (200) ; un moyen de rupture mécanique, qui peut interrompre le circuit de protection primaire (100) lorsqu'une surintensité se produit vers le circuit protégé (300) ; et un moyen de fusion, qui peut fondre lorsque le circuit de protection primaire (100) est rompu pour interrompre le circuit protégé (300).
(ZH) 一种断路器,包括串联在被保护电路(300)中的主保护电路(100);串联在被保护电路(300)中的辅助保护电路(200);主保护电路(100)与辅助保护电路(200)并联;机械断开装置,机械断开装置在被保护电路(300)发生过电流时断开主保护电路(100);熔断装置,熔断装置在主保护电路(100)断开后熔断而断开被保护电路(300)。
