产品详细资料
注意，三角形绕组电流比Y形绕组电流滞后30°，这与变压器铭牌一致。现在假设一个具有ACB序列的电源分别连接到变压器端子a、C、B。平衡负载的电流如下所示：注意，三角形绕组电流Y形绕组电流30°（在IEC术语中为Yd11型，在GE Multilin术语中为Y/d330型），这与变压器铭牌不一致。这是因为用于计算三角形绕组的电流的物理连接以及因此的方程没有改变。变压器铭牌相位关系信息仅适用于规定的相序。可以建议，对于ACB序列，通过将源相A、B和C分别连接到变压器端子A、C和B，可以将相位关系恢复到变压器铭牌上显示的相位关系。这将恢复铭牌上的相移，但会导致继电器内B相和C相的错误识别，因此不建议使用。720已使用
Note that the delta winding currents lag the wye winding currents by 30°, which is in agreement with the transformer nameplate. Now assume that a source, with a sequence of ACB is connected to transformer terminals A, C, B respectively. The currents that would be present for a balanced load are shown below:Note that the delta winding currents leads the wye winding currents by 30°, (which is a type Yd11 in IEC nomenclature and a type Y/d330 in GE Multilin nomenclature) which is in disagreement with the transformer nameplate. This is because the physical connections and hence the equations used to calculate current for the delta winding have not changed. The transformer nameplate phase relationship information is only correct for a stated phase sequence. It may be suggested that for the ACB sequence the phase relationship can be returned to that shown on the transformer nameplate by connecting source phases A, B and C to transformer terminals A, C, and B respectively. This will restore the nameplate phase shifts but will cause incorrect identification of phases B and C within the relay, and is therefore not recommended.
