Abstract
Изобретение относитс к электроэнергетике . Цель изобретени - расширение технологических возможностей испытательного оборудовани . К испытуемому трансформатору 2, к его первичной обмотке, подают напр жение от основного испытательного источника 1 переменного тока. После затухани тока включени трансформатора 2 к его вторичной обмотке подключают дополнительный источник тока 5, синхронизированный по частоте с первым источником . Регистрируетс показани датчиков 12 и 13 тока и напр жени на вторичных обмотках трансформаторов напр жени 10 и 11. При этом достигаетс исключение биени тока короткого замыкани при испытани х. Расширение технологических возможностей испытательного оборудовани достигаетс за счет улучшени использовани мощности нескольких фаз и увеличени числа возможных вариантов схем испытаний. 2 с. п. ф-лы, 1 ил. СThe invention relates to power engineering. The purpose of the invention is to expand the technological capabilities of the test equipment. The test transformer 2, to its primary winding, serves the voltage from the main test source 1 of alternating current. After attenuation of the switching current of the transformer 2, an additional current source 5, synchronized in frequency with the first source, is connected to its secondary winding. The readings of the current and voltage sensors 12 and 13 on the secondary windings of the voltage transformers 10 and 11 are recorded. In this case, the elimination of the short circuit current during testing is achieved. The expansion of the technological capabilities of the test equipment is achieved by improving the use of power of several phases and increasing the number of possible variants of test circuits. 2 sec. item f-ly, 1 ill.
