Description
Известны устройства дл оценки экономичности работы потребителей электрической энергии с помощью измерител коэффициента мощности.Devices are known for estimating the efficiency of an electrical energy consumer using a power factor meter.
Недостатком этих устройств вл етс то, что они не обеспечивают точной оценки рационального использовани электроэнергии.The disadvantage of these devices is that they do not provide accurate estimates of the rational use of electricity.
Предлагаемое устройство позвол ет более точно определить экономичность работы электросети на основе учета отклонени значени коэффициента мощности от установленного оптимального значени . Это достигаетс тем, что в устройстве применен св занный с осью подвижной системы измерител коэффициента мощности электрический датчик переменного тока, напр жение на выходе которого пропорционально углу отклонени указател прибора и равно нулю в положенич указател , соответствующем заданному значению коэффициента мощности . Датчик снабжен приспособлением дл программной установки его нулевой точки, соответственно с изменением по времени установленного значени коэффициента мощности. Новым вл етс также применение подключенного к датчику трансформатора с двум вторичными обмотками, предназначенными дл подключени к ним обмоток тока и напр жени электрического счетчика.The proposed device makes it possible to more accurately determine the efficiency of the operation of the power grid based on the consideration of the deviation of the value of the power factor from the set optimal value. This is achieved in that the device uses an electrical AC sensor connected to the axis of the moving system of the power factor meter, the output voltage of which is proportional to the deflection angle of the instrument pointer and is zero at the pointer position corresponding to the specified power factor value. The sensor is equipped with a device for programmatically setting its zero point, according to the time variation of the set value of the power factor. Also new is the use of a transformer with two secondary windings connected to the sensor, designed to connect current windings and electric meter voltages to them.
На чертеже изображена блок-схема устройства. Исследуема сеть через измерительные трансформаторы 1 и 2 тока и напр жени подключаетс к прибору 3. Прибор 3 представл ет собой измеритель коэффициента мощности, на оси которого укреплен,электрический датчик переменного тока, напр жение на выходе датчика зависит от угла поворота подвижной системы нрибора. При положении указател прибора на отметке щкалы, соответствующей оптимальному значению коэффициента мощности, напр жение датчика равно нулю и при переходе через эту отметку измен етс по фазе на 180°. Напр жение возбуждеThe drawing shows a block diagram of the device. The network under study is connected to the device 3 through the measuring transformers 1 and 2 of the current and voltage. Device 3 is a power factor meter, on the axis of which the electrical alternating current sensor is fixed, the voltage at the sensor output depends on the angle of rotation of the moving system. When the instrument pointer is at the mark, which corresponds to the optimum value of the power factor, the voltage of the sensor is zero and when passing through this mark it changes in phase by 180 °. Voltage is excited
