Description

Предлагаетс  устройство дл  измерени  посто нных токов, содержащее электрический генератор, обмотка возбуждени  которого питаетс  измер емым током, и подключенный к его зажимам электроизмерительный прибор.A device for measuring direct currents is proposed, which contains an electric generator, the field winding of which is powered by the measured current, and an electrical measuring device connected to its terminals.

Предлагаемое зстройство отличаетс  от известных устройств подобного рода тем, что обмотка возбуждени  генератора вынолнеиа секционированной дл  изменени  числа ее витков при переходе с одного диапазона измерений на другой.The proposed device differs from the known devices of this kind in that the excitation winding of a generator is sectioned to change the number of its turns when switching from one measurement range to another.

Такое д.стройство позвол ет расширить пределы его изме 1ени .Such a device allows one to expand the limits of its measurement.

В предлагаемом зстройстве (,см. схему) применен электрический генератор 1, приводимый во вращение с посто нной скоростью от синхронного электрического двигател  2. Измер емый ток питает обмотку 3 возбуждени  генератора, а на зажим  кор  подключен измер юпщ : его напр жение вольтметр 4, проградуированный в значени х тока возбуждени  генератора. Дл  получени  нескольких пределов измерени  прибора обмотка 3 возбуждени  генератора выполнена секционированной с различными числами витков в каждой секции.In the proposed device (see diagram), an electric generator 1 is applied, which is driven at constant speed from a synchronous electric motor 2. The measured current feeds the generator excitation winding 3, and the measuring terminal is connected to the core terminal: graduated in terms of generator excitation current. In order to obtain several measuring limits for the device, the generator excitation winding 3 is made sectioned with different numbers of turns in each section.

В зависимости от величины измер емого тока секции включаютс  в схему последовательно или параллельно. При необходимости могут включатьс  только отдельные секции или же они могут включатьс  таким образом, чтобы магнитные потоки, создаваемые каждой секцией вычитались .Depending on the magnitude of the measured current, the sections are included in the circuit in series or in parallel. If necessary, only individual sections may be included, or they may be included in such a way that the magnetic flux created by each section is subtracted.

Предмет изобретени Subject invention

Устройство дл  измерени  посто нных токов, содержащее электриче1:кий генератор, обмотка возбуждени  которого питаетс  измер емым током, и электроизмерительный прибор, градуированный непосредственно в значени х измер емого тока и подключенный к выходным зажимамA device for measuring direct currents, containing an electrical generator, the excitation winding of which is powered by the measured current, and an electrical measuring instrument, calibrated directly in the values of the measured current and connected to the output terminals

генератора, отличающеес  тем, что, с целью расширени  пределов измерени  устройства, обмотка возбуждени  генератора выполнена секционированной дл  получени  изменени  числа витков этой обмотки при переходе с одного диапазона измерений на другой.Generator, characterized in that, in order to expand the measurement limits of the device, the generator excitation winding is made sectioned to obtain a change in the number of turns of this winding when switching from one measurement range to another.
