Description
Предлагаемое устройство дл измерени мощности по схеме с твердыми выпр мител ми отличаетс от примен емых обычно схем тем, что в нем -включены, как указано на чертеже, два выпр мительные каскада А и В.The proposed power measuring device according to the circuit with solid rectifiers differs from the commonly used schemes in that it includes, as indicated in the drawing, two rectifying stages A and B.
На один из них действует сумма напр жени сети и падени напр жени в сопротивлении, включенном в цепь переменного тока, а на второй действует разность тех же напр жений . Посто нные токи от обоих устройств подвод тс к измерительному прибору с двум раздельно действующими электромагнитными системами.One of them is affected by the sum of the network voltage and the voltage drop in the resistance connected to the AC circuit, and the second is affected by the difference of the same voltage. The constant currents from both devices are supplied to the measuring device with two separately operating electromagnetic systems.
Схема позвол ет производить измерени величины и знака активной и реактивной мощности.The circuit allows measurements of the magnitude and sign of active and reactive power.
Предмет изобретени Subject invention
Устройство дл измерени мощности по схеме с твердыми выпр мител ми , включенными один на сумму напр жени сети и падени напр жени в сопротивлении, включенном в цепь главного тока, а второй на разность тех же напр жений , отличающеес тем. что в нем при.менен балансный измерительный прибор с двум раздельными , действующими друг другу навстречу, электромагнитными системами, обмотки которых получают питание от указанных выпр мителей .A device for measuring power according to a circuit with solid rectifiers connected one for the sum of the network voltage and voltage drop in the resistance connected to the main current circuit, and the other for the difference of the same voltage, characterized by that it contains a balanced measuring device with two separate electromagnetic systems operating to each other, the windings of which are powered by the said rectifiers.
