Because the harmonics in tangyin substation are primarily from electric traction loads, this paper gives the structures of several main locomotive models and general harmonics they produce. the harmonics produced by electric locomotive have a characteristic that their range and phase are both dispersive. this paper also analyzes the impedance - matching balance transformer ' s structure and harmonics injected into the power system at its primary side, and sums up the characteristics of the harmonics from electric traction loads in the tangyin traction substation
鑒于湯陰變電站的諧波主要來自電力牽引負荷，本文列舉了電力機車幾種主要車型的結構以及它們產生諧波的概況，得出了電力機車的各次諧波電流幅值和相角具有較大分散性的特點。針對湯陰牽引變電站的牽引變壓器，分析了阻抗匹配平衡變壓器的結構及其高壓側注入電網的諧波，推導了有關計算公式。通過理論分析並結合湯牽線的實測諧波數據，歸納了電力牽引負荷注入湯陰變電站的諧波的特點。 -
This test checks for proper connection, impedance balance between the phases and minor or impending short circuits in the windings

Conventional hybrids used in all existing phone patches can provide good balance at only one frequency into a complex impedance such as telephone line
傳統的混合線路採用所有現行的電話臨時線路技術，只能做到單一頻率的良好平衡進入如電話線的復數阻抗中。 -
But in fact, there are many windings on each leg of a balance transformer, and the winding impedance relationships that the balance condition requires are strict, so it is difficult to design and make such transformers. if adopting the connection scheme of dual windings, the windings on single leg will increase almost doubly. it is more difficult to satisfy the balance condition and probably it will confront conflict when arranging these windings, so parameters of various phases can not be balanced
事實上由於平衡變壓器單柱繞組數目較多，若採用雙重接線方案，則單柱繞組數目增加近一倍，滿足平衡條件十分困難，甚至使得繞組在空間上的布置產生矛盾，無法達到各相參數平衡的要求，而「四相四心柱「結構的三相變四相電力變壓器較好的解決了這一難題。 -
It is the simplest form among transformers in this kind. for evaluating the relationship between the error of winding impedance and the performance of the three - phase to four - phase power transformer, this paper uses “ matlab ” as a digital simulation platform to exam the mathematic model and analyze the balance condition as well as
因此，本文對不同排列方式，不同回數四相輸電線路的電場、磁場、無線電干擾和可聞噪聲進行了詳細的分析和計算，並把它們與三相輸電線路相應的電磁場參數進行了全面比較。 -
