Abstract
Sposób pomiaru prądów w obiektach elektroenergetycznych wielofazowych, w szczególności w trójfazowych układach szynowych generatorów, blokach generator - transformator, transformatorach energetycznych i stacjach elektroenergetycznych, przeznaczony zwłaszcza do stosowania w automatyce zabezpieczeniowej tych obiektów, w którym tory prądowe (T) sprzęga się magnetycznie z cewkami pomiarowymi (Cp), złączonymi następnie z członami pomiarowymi (P) napięcia, charakteryzuje się tym, że w obwody cewek pomiarowych (Cp) i członów pomiarowych (P) napięcia poszczególnych pomiarowych torów prądowych (T) wpina się szeregowo cewki kompensujące (Ck), sprzężone magnetycznie z torami prądowymi (T), sąsiadującymi z pomiarowym torem prądowym (T), które kompensują oddziaływanie prądów sąsiednich torów prądowych (T) na cewki pomiarowe (Cp) członów pomiarowych (P) napięcia poszczególnych pomiarowych torów prądowych (T). Przetwornik prądowo - napięciowy, służący do realizacji tego sposobu, zbudowany z kilku torów prądowych (T), z których co najmniej jeden stanowi pomiarowy tor prądowy (T), sprzężony magnetycznie z cewką pomiarową (Cp), która złączona jest następnie z członem pomiarowym (P) napięcia charakteryzuje się tym, że w obwód cewki pomiarowej (Cp) i członu pomiarowego (P) napięcia pomiarowego toru prądowego (T) włączona jest szeregowo co najmniej jedna cewka kompensująca (Ck), sprzężona magnetycznie z torem prądowym (T), sąsiadującym z pomiarowym torem prądowym (T).The method of measuring currents in multi-phase power facilities, in particular in three-phase generator busbar systems, generator-transformer blocks, power transformers and power stations, designed especially for use in the automation of these objects in which the current path (T) magnetically couples with measuring coils (Cp), then connected to the voltage measuring members (P), is characterized by the fact that in the circuits of the measuring coils (Cp) and measuring members (P), the voltages of individual measuring current paths (T) are connected in series compensation coils (Ck), coupled magnetically with current paths (T), adjacent to the measuring current path (T), which compensate the impact of the currents of adjacent current paths (T) on the measuring coils (Cp) of the measuring members (P), voltage of individual measuring current paths (T). Current-voltage transducer, used to implement this method, built of several current paths (T), at least one of which is the measuring current path (T), magnetically coupled with the measuring coil (Cp), which is then connected to the measuring element ( P) voltage is characterized by the fact that at least one compensation coil (Ck) in series with the measuring coil (Cp) and measuring element (P) of the measuring voltage (T) is magnetically coupled with the current path (T), adjacent with measuring current path (T).
