断路器子装置
摘要：
本发明涉及一种断路器子装置(50)。该子装置包括基座(475)、操作机构(65)、设置在基座(475)中的单件式非导电转子(105)、以及由转子(105)支撑的多组接触臂(190)。转子(105)设置成与操作机构(65)可操作地连接，并且包括相对于基座(475)的旋转自由度，同时转子(105)的部分设置在多组接触臂(190)的每一组之间以限定间隔部分(450)。操作机构(65)包括设置在基座(475)中的框架(310)、与框架(310)成枢转式连接的支架(340)、与支架(310)成枢转式连接的上部连接件(350)、以及具有第一端部(410)和第二端部(415)的下部连接件，第一端部(410)与上部连接件(350)成枢转式连接，而第二端部(415)在间隔部分(450)处与转子(105)成枢转式连接。
摘要（英）：

A circuit breaker subassembly (50) is disclosed. The subassembly includes a base (475), an operating mechanism (65), a one-piece non-conductive rotor (105) disposed within the base (475), and a plurality of sets of contact arms (190) supported by the rotor (105). The rotor (105) is disposed in operable connection with the operating mechanism (65) and includes a rotational degree of freedom relative to the base (475) with portions of the rotor (105) disposed between each set of the plurality of sets of contact arms (190) to define separation portions (450). The operating mechanism (65) includes a frame (310) disposed within the base (475), a cradle (340) in pivotal connection with the frame (310), an upper link (350) in pivotal connection with the cradle (340), and a lower link having a first end (410) and a second end (415), the first end (410) in pivotal connection with the upper link (350) and the second end (415) in pivotal connection with the rotor (105) at the separation portions(450).
