Description
Известны комперюационные устройства дл измерени мощности, содержащие два отдельных компенсатора, замер ющих ток и напр жение в контролируемой цепи и осуществл ющих компенсацию измене нием рабочего тока.Compensation devices for measuring power are known, comprising two separate compensators measuring current and voltage in a controlled circuit and compensating for changes in the operating current.
Особенностью предлагаемого компенсационного устройства, обеспечивающей возможность непосредственного отсчета значени измер емой мощности по шкале компенсатора, вл етс последовательное включение потенциометров компенсаторов тока и напр жени в общую цепьрабочего тока и применение третьего потенциометра, включенного парал лельно нагрузке контролируемой сети. Движок этого потенциометра механически св зан с движком потенциометра компенсации тока и электрически соединен с движком потенциометра напр жени через нулевой гальванометр.The peculiarity of the proposed compensation device, which makes it possible to directly measure the measured power value on the compensator scale, is the sequential connection of the potentiometers of the current and voltage compensators to the common operating current and the use of a third potentiometer connected in parallel to the load of the monitored network. The engine of this potentiometer is mechanically connected to the engine of the current compensation potentiometer and electrically connected to the engine of the voltage potentiometer via a zero galvanometer.
Такое устройство позвол ет после осуществлени компенсации измер емого тока перемещением движка потенциометра тока отсчитать величину измер емой мощности по щкале потенциометра напр жени .Such a device allows, after performing the compensation of the measured current by moving the current potentiometer slider, to measure the value of the measured power in the slider of the voltage potentiometer.
На чертеже представлена принципиальна электрическа схема предлагаемого компенсационного устройства.The drawing shows a circuit diagram of the proposed compensation device.
Как видно из чертежа, потенциометры 1 и 2 компенсаторов напр жени и тока включены в цепь рабочего тока I последовательно с установочным сопротивлением 3 и регулировочным сопротивлением 4. Общее сопротивление этой цепи не зависит от положени движков 5 и 6 потенциометров 1 тл 2. Параллельно нагрузке 7 контролируемой цепи включен третий потенциометр 8, движок .9 которого жестко св зан с движком 6 потенциометра 2 тока и электрически соединен через нулевой гальванометр 10 с движком 5 потенциометра напр Лсени /.As can be seen from the drawing, potentiometers 1 and 2 of voltage and current compensators are included in the operating current circuit I in series with adjusting resistance 3 and adjusting resistance 4. The total resistance of this circuit does not depend on the position of the sliders 5 and 6 of potentiometers 1 TL 2. Parallel to the load 7 the monitored circuit includes a third potentiometer 8, the slider .9 of which is rigidly connected to the slider 6 of the current potentiometer 2 and electrically connected through a zero galvanometer 10 to the slider 5 of the potentiometer eg Leni /.
Процесс измерени мощности заключаетс в установке рабочего тока /к, компенсации измер емого тока / в нагрузке 7 и компенсации падени напр жени на части 8 сопротивлени потенциометра 8.The process of power measurement consists in setting the operating current / k, compensating the measured current / in the load 7, and compensating for the voltage drop across the resistance part 8 of the potentiometer 8.
Поставив ключ // в положение «а и включив гальванометр 12 (показан пунктиром) в цепь нормального элемента 13, производ т устаPutting the key // in the position "a" and turning on the galvanometer 12 (shown by dotted lines) in the chain of the normal element 13, the mouth
