| 摘要: |
| 现场试验是继电保护安装、调试和检修维护的重要组成部分,是保证继电保护及其二次设备具备良好运行状态的一种有效措施。针对现场试验中带负荷检查存在的问题、高频保护中通道问题、光纤保护中远跳功能应注意的问题等,指出应特别关注的问题。还提出了现场试验中几种典型的试验方法:跳闸回路的绝缘试验、装置电源对地绝缘测量、电流互感器伏安特性测量及二次负载核算方法。 |

| Abstract: |
| Site test is an important procedure of relay protection installation,commissioning and main-tenance,and is an effective measure to guarantee the relay protection and its secondary equipment in normal operating state. Several typical problems existing in site test of relay protection are pointed out,such as test with load,channel test of high frequency protection,remote trip function test of optical protection. Several typical test methods are also provided,such as insulation test of tripping circuit,insulation measuring of power supply to ground,volt-ampere characteristic measurement of current transformer and secondary load check method. |
