摘　　要：分析了高压真空断路器"跳跃"的成因、类型及其危害,可在控制回路或断路器本体上采取防跳措施。综合继电保护装置中的防跳措施不能防止断路器第二类"跳跃"的发生。当与断路器本体防跳组合起来时,需解决组合防跳的寄生现象。文章给出了几种目前常用的防跳控制回路,探讨了其不足之处,并针对寄生现象,结合实际,给出了防跳控制回路的三种改进措施。Anti-bounce measures can be taken in control loop or circuit breaker body based on analysis of the cause of formation, types and harm of high-voltage vacuum breaker＇s ＂bouncing＂ . The type 2 ＂bounce＂ in breaker can not be prevented against by the antibounee measures used in integrated relay protective devices. This paper gives some commonly used antibounce control circuits combined with anti-bounce measures in breaker body, its shortages are discussed and three improved measures for anti-bounce eontrol loop are presented upon considering parasitism phenomena and nractieal use.
