产品详情资料
在受保护区域发生接地故障时，相电流的剩余电流与中性电流之间的相位差大于90°，即剩余电流和中性电流的方向朝向受保护区域。在计算差分电流时，剩余电流和中性电流的方向经过加权，只有当相电流和中性流的剩余电流之间的相位差超过90°时，才能进行操作。相位差越小，即越接近90°，运行所需的差动电流越高。差动原理的工作特性在描述接地故障继电器模块SPCD 2D55的文件中给出。基本设置P1/In和P2/In的设置范围为5…50%。数值差动电流原理的操作在待保护绕组一侧的相电流（负载电流）方面是稳定的，因此相关侧的相电流平均值越高，启动所需的差动电流就越高，At an earth fault in the protected area the phase difference between the residual current of the phase currents and the neutral current is greater than 90°, i.e. the directions of the residual current and the neutral current are towards the protected area. In the calculation of the differential current the directions of the residual current and the neutral current are so weighted that operation is possible only if the phase difference between the residual current of the phase current and neutral current exceeds 90°. The smaller the phase difference, i.e. the closer it is to 90°, the higher the differential current required for operation. The operation characteristic for the differential principle is presented in the document describing the earth-fault relay module SPCD 2D55. The setting range of the basic settings P1/In and P2/In is 5...50%. The operation of the numerical differential current principle is stabilized in respect of the phase currents (load current) on the side of the winding to be protected so that the higher the average of the phase currents on the concerned side the higher is the differential current required for starting
