摘　　要：随着近些年真空断路器在各变电所、开闭所等电力系统中的大量应用,组合式过电压保护器也逐步在电力系统中大量安装使用,为避免大气过电压和内部操作过电压对电力系统内各高压电气设备造成损坏,确保电力系统安全可靠运行。通过多年运行经验,发现组合式过电压保护器有着优越的性能,在抑制、消除系统过电压方面具有很好的效果,同时发现在设计、制造、安装、试验、运行维护等各方面存在需要注意和改进的地方,如果在这些细节方面不加以注意和改进,在保护器运行过程中,必然要出现一系列问题,影响电力系统安全、可靠、持续、稳定运行,严重时会造成闪络、短路等电气设备安全事故,不仅严重损毁高压电气设备,甚至导致电力系统停电,造成严重经济损失及潜在的人身安全事故。以下就组合式过电压保护器结构、工作原理、安装及试验等方面注意事项做详细介绍,用以在高压电力系统中使用组合式过电压保护器作为参考。With the widespread application of vacuum circuit breakers in various substations,switching stations and other power systems in recent years,combined overvoltage protectors have gradually been installed and used in large quantities in the power system to avoid damage to high-voltage electrical equipment in the power system caused by atmospheric overvoltage and internal operation overvoltage,and to ensure the safe and reliable operation of the power system.Through years of operating experience,it has been found that the combined overvoltage protector has superior performance and has a good effect in suppressing and eliminating system overvoltage.At the same time,it has also been found that there are areas that need attention and improvement in design,manufacturing,installation,testing,operation and maintenance.If these details are not paid attention to and improved,a series of problems will inevitably arise during the operation of the protector,affecting the safety,reliability,continuous and stable operation of the power system.In severe cases,it can cause electrical equipment safety accidents such as flashover and short circuit,not only seriously damaging high-voltage electrical equipment,but also causing power outages in the power system,resulting in serious economic losses and potential personal safety accidents.The following provides a detailed introduction to the structure,working principle,installation,and testing precautions of the combined overvoltage protector,which can be used as a reference for the use of combined overvoltage protectors in high-voltage power systems.
