Title
(EN) Plug-in circuit breaker
(ZH) 插入式断路器
Abstract
(EN) The invention relates to the field of low-voltage electric appliances, particularly to a plug-in circuit breaker, which comprises a protection electrode, wherein one end of the operation button of theprotection electrode is inserted into a circuit breaker shell, the operation button, a first wire outlet end and a first wire inlet terminal are arranged at the two ends of the circuit breaker shellrespectively, an arc extinguishing system is arranged in the middle of a protection electrode assembly cavity and located on one side of the first wire inlet terminal, an operation mechanism is arranged between the operation button and the arc extinguishing system, a protection mechanism is arranged between a first wire outlet terminal and the arc extinguishing system and located on one side of the operation mechanism, the plug-in circuit breaker is in a closed state, the operation mechanism is in a lock catch state, when a short circuit state or an overload state exists, the protection mechanism drives the operation mechanism to trip, the plug-in circuit breaker trips and the operation mechanism enters the tripping state, the operation button is pulled to move towards the opening direction, the operation mechanism is driven to recover to the lock catch state, and the plug-in circuit breaker enters the opening state. The plug-in circuit breaker is compact in structure and small in size.
(ZH) 本发明涉及低压电器领域,具体涉及一种插入式断路器,其包括保护极,保护极的操作按钮一端插置在断路器壳体内,操作按钮和第一出线端、第一进线端子分别设置在断路器壳体的两端,灭弧系统设置在保护极装配腔中部且位于第一进线端子一侧,操作机构设置在操作按钮和灭弧系统之间,保护机构设置在第一出线端子和灭弧系统之间且位于操作机构一侧;所述插入式断路器处于合闸状态,操作机构处于锁扣状态,短路或过载时,保护机构驱动操作机构脱扣,插入式断路器跳闸且操作机构进入脱扣状态,拉拔操作按钮使其向分闸方向移动,驱动操作机构恢复至锁扣状态,插入式断路器进入分闸状态;本发明插入式断路器,其结构紧凑、体积小。
