PSIM User Manual phần 3

Trong những hình ảnh, p đề cập đến chính, s đề cập đến trung học, và t đề cập đến đại học. Quanh co với dấu chấm lớn hơn là các cuộn sơ cấp (hoặc quanh co tiểu học đầu tiên cho 2 chính 2 trung mấu biến áp (TF_1F_4W)). Đối với cuộn dây nhiều máy biến áp, trình tự của các cuộn dây từ trên xuống dưới. Đối với các máy biến áp với 2 hoặc 3 cuộn dây, các thuộc tính như sau | Transformers Images TF_1F TF_1F_3W TF_1F_5W TF_1F_5W _1 TF_1F_7W TF_1F_8W 1 3 a UÚ 0 p-13 1 UU s-1 s-2 p-1 nn N 1 23 sj 1 3 s-4 n J. n TF_ 1F_1 TF 1F 4W p 2D Ộ 3 1 m LJLJ n ủ In the images p refers to primary 5 refers to secondary and t refers to tertiary. The winding with the larger dot is the primary winding or the first primary winding for the 2-primary-2-secondary-winding transformer TF_1F_4W . For the multiple winding transformers the sequence of the windings is from the top to the bottom. For the transformers with 2 or 3 windings the attributes are as follows. Attributes Parameters Description Rp primary Rs secondary Rt tertiary Lp pri. leakage Ls sec. leakage Lt ter. leakage Lm magnetizing Np primary Ns secondary Nt tertiary Resistance of the primary secondary tertiary winding in Ohm Leakage inductance of the primary secondary tertiary winding in H seen from the primary Magnetizing inductance in H No. of turns of the primary secondary tertiary winding All the resistances and inductances are referred to the primary side. For the transformers with more than 1 primary winding or more than 3 secondary windings the attributes are as follows.

Example A single-phase two-winding transformer has a winding resistance of 0.002 Ohm and leakage inductance of 1 mH at both the primary and the secondary side all the values are referred to the primary . The magnetizing inductance is 100 mH and the turns
