标准摘要
[中文适用范围]: IEC60255的本部分以IEC61000-4-5为基础,适用时参考该出版物,规定了用于电力系统保护的测量继电器和保护设备的浪涌抗扰度试验的一般要求,包括所用的控制、监测和过程接口设备与这些系统。测试的目的是确认被测设备在通电并受到开关和雷电效应引起的浪涌电压引起的电源和互连线路上的高能干扰时能够正常运行。本标准无意测试绝缘承受高压应力的能力。 IEC 60255-27 涵盖了绝缘测试。本标准规定的要求适用于新状态下的测量继电器和保护设备,规定的所有试验仅为型式试验。本标准的目的是定义: 〜使用的术语; ~ 测试严重程度; 〜测试设备; 〜测试设置; 〜测试程序; ~ 接受标准; 〜测试报告要求。 [外文原描述]: IEC 60255-22-5:2008 specifies the general requirements for surge immunity tests for measuring relays and protection equipment for power system protection, including the control, monitoring and process interface equipment used with those systems. Is based on IEC 61000-4-5. The objective of the tests is to confirm that the equipment under test will operate correctly when energized and subjected to high-energy disturbances on the power and interconnection lines, caused by surge voltages from switching and lightning effects. The main change in this new edition concerns line to earth tests.
