Combined with the "grassroots cadres contact farmers" activities and each cadres to contact a people, by 减少不必要的中间传动环节降低了能耗和噪声，使断路器的功能更加可靠。 5.4 该断路器具有寿命长，维护简单，无污染，无爆炸危险，噪音低等优点，比适用于频繁操作等条件比较苛刻的工作条件。断路器即可装入手车式开关柜。也可用于固定式开关柜。 6. 工作原理 6.1 储能动作 断路器合闸所需能量由合闸弹簧储能提供。储能即可由外部电源驱动电机完成，也可使用储能手柄手动完成。 储能操作:固定在框架上的储能电机15通电输出扭矩，通过电机输出轴16的单向轴承13带动链轮14转动，或者将储能受柄插入手动储能孔中顺时针摇动，通过蜗轮蜗杆(10，11)带动链轮14转动。然后通过链条9带动链轮3转动，链轮3转动时，档销1推动轮5上的滑块2使储能轴21跟随转动， 并通过两边拐臂19拉伸合闸弹簧进行储能.到达储能位置时，框架上的限位杆压下滑块2，使储能轴与链轮传动系统脱开，储能保持掣子7顶住滚轮6保持储能位置，同时储能轴上拨板23带动储能指示牌翻转，显示已储能标记，并切换行程开关，切断储能电机供电电源，此时断路器处于合闸准备状态。 6.2 合闸操作 机构储能后，若接到合闸信号，合闸电磁铁17动作或按下合闸按钮，使储能保持轴8转动，带动掣子7松开滚轮6，解除储能保持，合闸弹簧18释放能量，使储能轴21和轴上的凸轮22作顺时针转动，通过转动拐臂36，传动连板37带动绝缘拉杆34带动动触头向上运动进入合闸位置，并压缩触头弹簧33，保持触头所需接触压力。 合闸动作完成后，由合闸掣子40与半轴42保持合闸位置,同时储能指示牌，储能行程开关复位，电机供电回路接通，合分指示牌显示“合”标记，若外接电源也接通则再次进入储能状态。 注:当断路器已处于合闸状态或选用闭锁装置而未接通外接电源及手车式断路器在推进过程中，均不能进行合闸操作。 6.3 分闸操作 合闸动作完成后，一旦接到分闸信号或按分闸按钮，分闸脱扣电磁铁或过流脱扣电磁铁动作，使分闸半轴42对合闸保持掣子40的约束被解除。由触头簧33和分闸35储存的能量使灭弧室29动静触头分离而实现分闸操作。在分闸过程后段，由液压缓冲器吸收分闸过程剩余能量并限定分闸位置。 合分指示牌显示出“分”标记，同时拉动计数器43，实现计数器计数，由传动连杆拉动主辅助开关切换。 7. 防误联锁 7.1 断路器合闸操作完成后，合闸联锁弯板2向下运动扣住合闸保持轴上的合闸弯板3，在断路器未分闸时将不能再次合闸。 7.2 断路器在合闸结束后，如合闸电信号未及时去除，断路器内部防跳控制回路将切断合闸回路防止多次重合闸。 7. 3 手车式断路器在未到实验位置或工作位置时，由联锁弯板4扣住合闸脱扣3上的销5，断路器将不能合闸，防止断路器处于合闸状态进入负荷区。 7.4 手车式断路器在工作位置或试验位置合闸后，由滚轮压推进机构锁板，手车将无法移动，防止在合闸状态拉出或推进负荷区。 7.5 如果选用电气合闸闭锁，在二次控制电源末接通情况下阻止手动进行合闸操作。 注意:合闸闭锁功率消耗为4.5W，在0.8-1.1倍额定电压可正常操作。 8. 安装，调试 8.1 拆箱 断路器从包装箱中起吊时，挂钩应挂在断路器上有明显标志的起吊机处，搬移时不得使上下出线臂受力，同时不应让断路器受到较大的冲击振动。 8.2 安装前检查 adership: Luo Mingjun, rectification time: before September 25th, insist for a long time) 1, 2, to further improve research, solve thoroughly, not solid, the effect is not obvious.
