摘　　要：由于受测试仪器、保护原理等条件限制,在工程现场对微机型继电保护进行测试时,可能存在不能直接获得所需要的试验电压的情况,为此,文章介绍两种获得微机继电保护装置所需试验电压的实现方法,并在对其原理进行分析和理论计算后,采用实际的继电保护装置进行验证,证明这两种方法是可行且正确有效的。Due to the limitation of test instruments,protection principle and other conditions,it may not be possible to obtain the required test voltage directly when testing the micro-processor based protection in the engineering site.Therefore,this paper introduces two methods to obtain the test voltage required by the micro-processor based protection equipment.After the principle analysis and theoretical calculation of these two methods,the actual relay protection equipment is used to verify that the two methods are feasible,correct and effective.
