摘　　要：继电保护装置跳闸出口触点的性能是评估继电器特性的一项重要指标,其在相关标准中有严格的安全性能规定和要求,但标准对于采用何种方法进行测试却没有明确规定。文中基于IEC60255-1标准规定的触点性能试验要求,从触点机械耐久、极限接通容量、通流能力、极限断开容量能力方面着手,通过理论计算,设计了继电器跳闸出口触点性能试验的方法,并实际搭建了电路进行测试。测试结果验证了所提方法可适用于继电保护装置跳闸出口触点的性能试验。The performance of the tripping output contact of the protection device is an important index for assessing the characteristics of relays.There are strict rules and requirements on its safety performance in relevant standards.However,no explicit requirements are specified on the method for testing.According to the specified requirements of contact performance test in IEC 60255-1,this paper devises methods for testing the performance of the tripping output contact of relays through theoretical calculation by considering the mechanical endurance,the limit making capacity,the contact current and the limit breaking capacity.And circuits for testing are actually built.The test results have verified that the proposed methods are applicable to testing the performance of tripping output contacts of protection devices.
