摘　　要：船用断路器作为舰船电力系统重要的控制和保护设备,直接影响舰船系统的安全可靠性能。由于工作环境的特殊性,船用断路器不可避免地会受到海浪重复拍打引起的颠震载荷。为探究颠震载荷对断路器整机可靠性以及触头系统接触性能的影响,以某型船用真空断路器为研究对象,运用理论推导、数值分析和试验验证等方法探究断路器在颠震载荷下的动态响应特性,寻找船用断路器结构设计的薄弱环节和探究触头系统的颠震规律,为船用电器设备抗颠震设计提供了理论依据和参考。Marine circuit breaker,as an important control and protection equipment of shipboard power system,can directly affect the safe and reliable performance of the ship board system.Due to the special nature of the working environment,marine circuit breakers are inevitably subjected to bump loads due to repeated lapping of waves.In order to investigate the influence of the bump loads on reliability of the circuit breaker and the contact performance of the contact system,a certain marine vacuum circuit breaker is taken as the research object to explore the dynamic response characteristics of the circuit breaker under bump loads by the use of such methods as theoretical derivation,numerical analysis and test verification,find the weak link of the marine circuit breaker structure design and the bump regularity of the contact system,which has provided a theoretical basis and reference for the design of marine electrical equipment against bump.
