Насто щее изобретение относитс к области электроизмерительной техники.The present invention relates to the field of electrical measuring equipment.
Известны устройства дл измерени электрической мощности - ваттметры.An apparatus for measuring electrical power, wattmeters, is known.
Недостатком известных устройств вл етс наличие методической погрешности вследствие собственного потреблени его обмоток.A disadvantage of the known devices is the presence of a methodological error due to the self-consumption of its windings.
С целью повышени точности измерени устройство снабжено последовательно соединенными переменными активным и индуктивным емкостным сопротивлени ми и нуль-органом , причем последовательно соединенные сопротивлени включены между пол рными зажимами токовой обмотки и обмотки напр жени ваттметра, а нуль-орган - между пол рным зажимом обмотки напр жени и непол рным зажимом токовой обмотки.In order to improve measurement accuracy, the device is equipped with series-connected variable resistive and inductive capacitance resistances and a null organ, with series-connected resistances connected between the polar clamps of the current winding and the voltage winding of the wattmeter, and the null organ between the polar clamp of the voltage winding and a non-polar clamp current winding.
На чертеже приведена схема предлагаемого устройства.The drawing shows a diagram of the proposed device.
Устройство измерени электрической мощности содержит: токовую обмотку 1 и обмотку напр жени 2 ваттметра, индуктивное емкостное и активное сопротивлени 3, 4, нуль-орган 5, нагрузку потребител 6.The electric power measurement device contains: a current winding 1 and a voltage winding 2 of a wattmeter, an inductive capacitive and active resistance 3, 4, a zero-organ 5, a load of the consumer 6.
Обмотка напр жёни 2 ваттметра подключаетс в сеть .«.ерез.последовательно соединенные переменные активное и реактивное сопротивлени 3, 4. Регулиру последние, добиваютс чтобы напр жение на обмотке 2 точно совпадало с напр жением на нагрузке потребител 6, что фиксируетс нуль-органом 5. Таким образом, ток потреблени обмотки 2 не протекает через токовую обмотку 1 ваттметра, чем исключаетс его методическа погрешность вследствие собственного потреблени обмоток.The winding of the voltage of 2 wattmeters is connected to the network. "Sequentially connected variables of active and reactive resistances 3, 4. The regulator of the latter ensures that the voltage on the winding 2 exactly coincides with the voltage on the load of the consumer 6, which is fixed by the zero authority 5 Thus, the current consumption of the winding 2 does not flow through the current winding 1 of a wattmeter, which eliminates its methodological error due to its own consumption of the windings.
Нредмет изобретени Nredmet of the invention
Устройство дл измерени электрической мощности, содержащее ваттметр, отличающеес тем, что, с целью повышени точности измерени , оно снабжено последовательно соединенными переменными активным и реактивным сопротивлени ми и пуль-оргапом, причем указанные сопротивлени включены между пол рными зажимами токовой обмотки и обмотки напр жени ваттметра, а нуль-орган - между пол рным зажимом обмотки напр жени и непол рнь1м зажимом токовой обмотки .,A device for measuring electrical power, comprising a wattmeter, characterized in that, in order to improve the measurement accuracy, it is equipped with series-connected variable active and reactive resistances and a pulsed orgap, and these resistances are connected between the polar terminals of the current winding and the wattmeter winding , and the null organ is between the polar terminal of the voltage winding and the half terminal of the current winding.,
