CN105513913A 一种采用中置式操动机构的高压断路器 无效 - 驳回 复审申请

一种采用中置式操动机构的高压断路器
摘要：
本发明提供的一种采用中置式操动机构的高压断路器，高压断路器包括A相瓷套、B相瓷套、C相瓷套、中置式操动机构和传动结构；A相瓷套、B相瓷套、C相瓷套均包括上瓷套、下瓷套和接线板，所述上瓷套和下瓷套通过接线板连接，上瓷套和下瓷套内部分别设有灭弧室和绝缘拉杆，绝缘拉杆一端与灭弧室连接，其另一端和中置式操动机构均连接传动结构。本发明提供的采用中置式操动机构的高压断路器中，驱动电机配置于中间位置，实现操动力的平衡及传动；采用永磁同步电机代替弹簧操动机构，实现机构零件的简化、方便更换、控制灵活；本发明结构形式简单牢靠、转动惯量小、重量轻，易于实现。
摘要（英）：

The invention provides a high-voltage circuit breaker adopting a built-in type operating mechanism, wherein the high-voltage circuit breaker comprises an A phase ceramic sleeve, a B phase ceramic sleeve, a C phase ceramic sleeve, a built-in type operating mechanism and a transmission mechanism; each of the A phase ceramic sleeve, the B phase ceramic sleeve and the C phase ceramic sleeve comprises an upper ceramic sleeve, a lower ceramic sleeve and a wiring board, the upper ceramic sleeve and the lower ceramic sleeve are connected through the wiring board, an arc extinguish chamber is arranged in the upper ceramic sleeve, a insulated pull rod is arranged in the lower ceramic sleeve, one end of the insulated pull rod is connected with the arc extinguish chamber, and the other end and the built-in type operating mechanism are connected with the transmission mechanism separately. According to the invention, a driving motor is arranged on the middle part of the high-voltage circuit breaker to realize the balance and transmission of the actuating force; a permanent magnet synchronous motor adopted by the circuit breaker replaces a spring operating mechanism, so that the mechanism and components are simplified, can be change conveniently and control flexibly; the structure of the circuit breaker has small rotational inertia and light weight, and is simple, reliable and easy to realize.
