Abstract
Ochrona układu izolacyjnego transformatora współpracującego z falownikami AC/DC/AC lub DC/AC o modulacji szerokości impulsów MSI charakteryzuje się tym, że w punktach połączenia falownika AC/DC/AC lub DC/AC z transformatorem jest włączony filtr pojemnościowy. W transformatorach trójfazowych filtr jest trójfazowy, a w transformatorach jednofazowych filtr jest jednofazowy. Filtr pojemnościowy (1) składa się z kondensatorów C, bądź korzystnie z kondensatorów C i rezystorów R, albo kondensatorów C i indukcyjności L względnie kondensatorów C, rezystorów R i indukcyjności L, przy czym kondensatory C, rezystory R i indukcyjności L mogą być połączone w trójkąt lub w gwiazdę. W transformatorach podstawowych, w których stabilizacja napięcia wyjściowego jest realizowana poprzez transformator regulacyjny zasilany z falownika, filtr pojemnościowy (1) korzystnie jest włączyć do końcówek wejściowych transformatora regulacyjnego. W transformatorach podstawowych, w których stabilizacja napięcia wyjściowego jest realizowana poprzez transformator regulacyjny zasilany z falownika, przy czym falownik z regulacją napięcia jest zasilany z transformatora dodatkowego, to jeden filtr pojemnościowy (1) korzystnie jest włączyć do końcówek wejściowych transformatora regulacyjnego, a drugi filtr pojemnościowy (1), korzystnie jest włączyć do końcówek wyjściowych transformatora dodatkowego. Na farmach fotowoltaicznych (7), transformator (8) jest połączony z falownikiem (6), korzystnie jest włączyć filtr pojemnościowy (1) do końcówek wejściowych transformatora (8). Na farmach wiatrowych i w hydroelektrowniach w których generator elektryczny, poprzez falownik, jest połączony z transformatorem (8), to korzystnie jest włączyć filtr pojemnościowy (1) do końcówek wejściowych transformatora (8).Protection of the transformer insulation system cooperating with AC / DC / AC or DC / AC inverters with pulse width modulation MSI is characterized by the fact that the capacitive filter is switched on at the connection points of the AC / DC / AC or DC / AC inverter. In three-phase transformers, the filter is three-phase, and in single-phase transformers the filter is single-phase. The capacitive filter (1) consists of capacitors C, or preferably of capacitors C and resistors R, or capacitors C and inductance L or capacitors C, resistors R and inductance L, whereby the capacitors C, resistors R and inductances L can be combined in triangle or star. In basic transformers, in which the output voltage is stabilized by a control transformer supplied from the inverter, the capacitive filter (1) is preferably connected to the input terminals of the control transformer. In basic transformers, in which the output voltage is stabilized by means of a control transformer supplied from the inverter, where the adjustable-voltage inverter is supplied from the additional transformer, one capacitive filter (1) is preferably connected to the input terminals of the control transformer, and the other is a capacitive filter (1), it is preferable to include an additional transformer in the output terminals. On solar farms (7), the transformer (8) is connected to the inverter (6), it is preferable to include a capacitive filter (1) at the input terminals of the transformer (8). On wind farms and hydroelectric plants in which the electric generator, through the inverter, is connected to the transformer (8), it is advantageous to include a capacitive filter (1) to the input terminals of the transformer (8).
