ABB框架断路器跳跃故障诊断及维护技术的应用！〔摘要〕本文介绍了云浮发电厂多起ABB低压框架断路器跳跃，弹簧储能机构反复储能，从而导致了断路器本体机构严重变形、负载设备损坏的问题，对故障进行分析，并结合实践经验总结有效的维护措施，提高ABB低压框架断路器安全使用。〔关键词〕框架断路器；弹簧储能；操作机构针对多起断路器跳跃故障，分析其原因有以下几方面：（1）合闸半轴两端与侧板孔间隙窄摩擦力太大，导致合闸半轴存在回位缓慢或卡涩，在每次合闸后，电机会自动对弹簧进行储能操作，造成当电动储能到位后，合闸半轴仍未到位，于是弹簧能量无法挂扣住，并瞬间释放掉，然后重新储能，如此反复，如果合闸半轴在期间***到位，储能机构会停止储能，否则会一直储能，将会打坏内部操作机构，直到拉开控制电源才停止。（2）工作电源断路器由于需长期运行，未进行操作机构***，驱动轴承、分合闸钩块、小轴及转动部位缺少定期润滑，机构积尘或卡涩导致操作故障。（3）环境和运行温度的影响，长期的高温运行，断路器操作机构上使用的润滑脂受温度影响后的有效作用时间缩短，导致操作机构内部润滑不畅，如电除尘、除灰等高负荷低压配电断路器，故障率明显高于其他低负荷配电断路器。（4）开关的操作频率低，根据生产厂家的建议，对于操作频率较低或者平时不进行操作的断路器，需要定期对其进行切换操作，以改善操作机构的润滑坏境，防止久不操作的断路器机构内部发生粘住，而实际上，在机组正常运行的前提下，配电系统的断路器是较少进行切换的。（5）维护周期过长，在机组稳定运行的前提下，低压配电断路器的停运机会较少，部分开关的维护无法做到每年一次，储能机构的润滑环境恶化而致故障。E3N3200R2000PR122/P-LIFHR3PACC:M220V,YO220V,YC220V,4CO,CP-EE3N3200***00PR121/P-LIFHR4PACC:M220V,YO220V,YC220V,4COE3N3200***00PR122/P-LIFHR4PACC:M220V,YO220V,YC220V,4CO,CP-EE3N3200***00PR122/P-LIWMP3PACC:M220V,YO220V,YC220V,4CO,CP-EE3N3200***00PR122/P-LIWMP4PACC:M220V,YO220V,YC220V,4CO,CP-EE3N3200***00PR121/P-LIWMP4PACC:M220V,YO220V,YC220V,4COE3N3200R2000PR121/P-LIWMP4PACC:M220V,YO220V,YC220V,4COE3N3200***00PR121/P-LIWMP3PACC:M220V,YO220V,YC220V,4COE3N3200R2000PR121/P-LIWMP3PACC:M220V,YO220V,YC220V,4COE3N3200R2000PR122/P-LIWMP3PACC:M220V,YO220V,YC220V,4CO,CP-EE3N3200R2000PR122/P-LIWMP4PACC:M220V,YO220V,YC220V,4CO,CP-EE3N3200***00PR122/PC-LSIWMP3PACC:M220V,YO220V,YC220V,YU220V,4CO,CP-EE3N3200***00PR122/PC-LSIWMP3PACC:M220V,YO220V,YC220V,4CO,CP-EE3N3200***00PR122/PD-LSIWMP3PACC:M220V,YO220V,YC220V,4CO,CP-EE3N3200***00PR122/PD-LSIWMP4PACC:M220V,YO220V,YC220V,4CO,CP-EE3N3200***00PR122/PV-LSIWMP3PACC:M220V,YO220V,YC220V,4CO,CP-EE3N3200***00PR122/PD-LSIFHR3PACC:M220V,YO220V,YC220V,4CO,CP-EE3N3200***00PR123/PD-LSIWMP4PACC:M220V,YO220V,YC220V,4CO,CP-EE3N3200***00PR123/PD-LSIWMP3PACC:M220V,YO220V,YC220V,4CO,CP-EE3N3200***00PR122/PC-LSIWMP4PACC:M220V,YO220V,YC220V,4CO,CP-EE3N3200***00PR121/P-LSIFHR3PACC:M220V,YO220V,YC220V,4COE3N3200***00PR123/P-LSIFHR3PACC:M220V,YO220V,YC220V,4CO,CP-EE3N3200R2000PR123/P-LSIFHR3PACC:M220V,YO220V,YC220V,4CO,CP-EE3N3200***00PR121/P-LSIFHR4PACC:M220V,YO220V,YC220V,4COE3N3200R2000PR122/P-LSIFHR3PACC:M220V,YO220V,YC220V,4CO,CP-EE3N3200***00PR122/P-LSIFHR3PACC:M220V,YO220V,YC220V,4CO,CP-EE3N3200R2000PR121/P-LSIFHR3PACC:M220V,YO220V,YC220V,4COE3N3200***00PR123/P-LSIFHR4PACC:M220V,YO220V,YC220V,4CO,CP-EE3N3200R2000PR121/P-LSIFHR4PACC:M220V,YO220V,YC220V,4COE3N3200R2000PR122/P-LSIFHR4PACC:M220V,YO220V,YC220V,4CO,CP-EE3N3200***00PR122/P-LSIFHR4PACC:M220V,YO220V,YC220V,4CO,CP-EE3N3200R2000PR123/P-LSIFHR4PACC:M220V,YO220V,YC220V,4CO,CP-EE3N3200***00PR123/P-LSIWMP3PACC:M220V,YO220V,YC220V,4CO,CP-EE3N3200R2000PR123/P-LSIWMP4PACC:M220V,YO220V,YC220V,4CO,CP-EE3N3200R2000PR123/P-LSIWMP3PACC:M220V,YO220V,YC220V,4CO,CP-EE3N3200R2000PR122/P-LSIWMP3PACC:M220V,YO220V,YC220V,4CO,CP-EE3N3200R2000PR122/P-LSIWMP4PACC:M220V,YO220V,YC220V,4CO,CP-EE3N3200***00PR123/P-LSIWMP4PACC:M220V,YO220V,YC220V,4CO,CP-EE3N3200R2000PR121/P-LSIWMP3PACC:M220V,YO220V,YC220V,4COE3N3200R2000PR121/P-LSIWMP4PACC:M220V,YO220V,YC220V,4COE3N3200***00PR122/P-LSIWMP3PACC:M220V,YO220V,YC220V,4CO,CP-EE3N3200***00PR122/P-LSIWMP4PACC:M220V,YO220V,YC220V,4CO,CP-EE3N3200***00PR121/P-LSIWMP3PACC:M220V,YO220V,YC220V,4COE3N3200***00PR121/P-LSIWMP4PACC:M220V,YO220V,YC220V,4COE3N3200***00PR122/PD-LSIGWMP4PACC:M220V,YO220V,YC220V,4CO,CP-EE3N3200***00PR122/PC-LSIGWMP4PACC:M220V,YO220V,YC220V,4CO,CP-EE3N3200***00PR122/PD-LSIGWMP3PACC:M220V,YO220V,YC220V,4CO,ExtCT,CP-EE3N3200***00PR122/PVD-LSIWMP4PACC:M220V,YO220V,YC220V,4CO,CP-EE3N3200***00PR123/P-LSIWMP4PACC:M220V,YO220V,YC220V,10CO,CP-EE3N3200***00PR122/PC-LSIGWMP3PACC:M220V,YO220V,YC220V,4CO,ExtCT,CP-EE3N3200***00PR122/PK-LSIGWMP4PACC:M220V,YO220V,YC220V,4CO,CP-E,InputPR120/KE3N3200R2000PR121/P-LSIGFHR3PACC:M220V,YO220V,YC220V,4CO,ExtCTE3N3200***00PR121/P-LSIGFHR3PACC:M220V,YO220V,YC220V,4CO,ExtCTE3N3200***00PR122/P-LSIGFHR3PACC:M220V,YO220V,YC220V,4CO,ExtCT,CP-EE3N3200R2000PR122/P-LSIGFHR3PACC:M220V,YO220V,YC220V,4CO,ExtCT,CP-EE3N3200R2000PR121/P-LSIGFHR4PACC:M220V,YO220V,YC220V,4COE3N3200***00PR122/P-LSIGFHR4PACC:M220V,YO220V,YC220V,4CO,CP-EE3N3200R2000PR122/P-LSIGFHR4PACC:M220V,YO220V,YC220V,4CO,CP-EE3N3200***00PR121/P-LSIGFHR4PACC:M220V,YO220V,YC220V,4COE3N3200***00PR123/P-LSIGFHR4PACC:M220V,YO220V,YC220V,4CO,CP-EE3N3200***00PR123/P-LSIGFHR3PACC:M220V,YO220V,YC220V,4CO,ExtCT,CP-EE3N3200R2000PR123/P-LSIGFHR3PACC:M220V,YO220V,YC220V,4CO,ExtCT,CP-EE3N3200R2000PR123/P-LSIGFHR4PACC:M220V,YO220V,YC220V,4CO,CP-EE3N3200R2000PR122/P-LSIGWMP4PACC:M220V,YO220V,YC220V,4CO,CP-EE3N3200***00PR122/P-LSIGWMP3PACC:M220V,YO220V,YC220V,4CO,ExtCT,CP-EE3N3200R2000PR121/P-LSIGWMP3PACC:M220V,YO220V,YC220V,4CO,ExtCTE3N3200R2000PR122/P-LSIGWMP3PACC:M220V,YO220V,YC220V,4CO,ExtCT,CP-EE3N3200***00PR122/P-LSIGWMP4PACC:M220V,YO220V,YC220V,4CO,CP-EE3N3200R2000PR123/P-LSIGWMP4PACC:M220V,YO220V,YC220V,4CO,CP-EE3N3200***00PR123/P-LSIGWMP4PACC:M220V,YO220V,YC220V,4CO,CP-EE3N3200R2000PR123/P-LSIGWMP3PACC:M220V,YO220V,YC220V,4CO,ExtCT,CP-EE3
