Abstract: Изобретение относится к электроизмерительной технике и предназначено для поверки шунтов постоянного тока в широком диапазоне измеряемых величин. Устройство содержит эталонную меру сопротивления, выполненную в виде трех параллельно соединенных резисторов с ненормируемой погрешностью с возможностью их отключения из измерительной цепи и изменения коэффициента преобразования эталонной меры сопротивления. Определение погрешности шунтов постоянного тока производится при помощи двухрядного потенциометра постоянного тока, к зажимам первого ряда которого присоединены потенциальные зажимы эталонной меры сопротивления, а к зажимам второго ряда присоединены потенциальные зажимы поверяемого шунта. Параллельно шунту присоединены резистор, имитирующий сопротивление измерительного прибора, и эталонная катушка сопротивления с возможностью их отключения из измерительной цепи, при этом номинальное значение сопротивления третьего резистора эталонной меры сопротивления с большим сопротивлением равно номинальному значению сопротивления резистора, имитирующего сопротивление измерительного прибора. Технический результат - повышение точности поверки шунтов постоянного тока в рабочих условиях в широком диапазоне измеряемых величин при конструктивном упрощении устройства. 1 ил.
