Description

Предлагаетс  устройство дл  измерени  электрического сопротивлени  медных катушек электрических маидин по методу сравнени . В известных устройствах подробного рода в качестве измерител  используют логометр, в цепь одной из рамок которого включаетс  измер емое сопротивление, а в цепь другой - регулируемый эталонный магазин сопротивлений .A device is proposed for measuring the electrical resistance of copper coils of electrical maidine by the comparison method. In the well-known devices of the detailed kind, a logometer is used as a meter, the circuit of one of the frames of which includes the measured resistance, and the other one - an adjustable reference resistance magazine.

Предлагаемое устройство отличаетс  от известных тем, что сопротивлени  эталонного магазина сопротивлений изготовл ют из того же материала, что и материал измер емых катушек. Такое выполнение устройства позвол ет устранить погрешность измерени , вызванную наличием температурного коэффициента электрического сопротивлени  материала провер емой катушки.The proposed device differs from the known ones in that the resistors of the reference resistance box are made of the same material as the material of the measured coils. Such an embodiment of the device makes it possible to eliminate the measurement error caused by the presence of the temperature coefficient of the electrical resistance of the material of the tested coil.

В предлагаемом устройстве (см. схему) измерение электрического сопротивлени  катушек пр оизводитс  по методу сравнени  с помошьго логометра 1. В цепь одной из рамок логометра включают измер емое сопротивление J д., а в цепь другой - эталонный магазин сопротивлений 2. Дл  устранени  вли ни  температурного коэффициента электрического сопротивлени  материала катушек на результаты измерений эталонный магазин выполн етс  из медных сопротивлений с тем же температурным коэффициентом сопротивлени .In the proposed device (see diagram), the measurement of the electrical resistance of the coils is carried out using the comparison method with a logometer 1. In the circuit of one of the frames of the gauge, the measured resistance Jd is included, and in the circuit of the other, the reference resistance magazine 2. the temperature coefficient of electrical resistance of the material of the coils on the measurement results of the reference magazine is made of copper resistances with the same temperature coefficient of resistance.

В устройстве имеютс  так же переключатели диапазонов 3 vi 4, магазин сопротивлений 5 из манганина, с помощью которого шкалы прибора дл  всех диапазонов свод тс  в одну, а так же сопротивлени  6 и 7 регулировани  верхнего и нижнего пределов измерени . Конденсатор о служит дл  сглаживани  пульсаций тока в измерительной цепи.In the device there are also switches of ranges 3 vi 4, resistance box 5 from manganin, with which the instrument scales for all ranges are combined into one, as well as resistances 6 and 7 for adjusting the upper and lower limits of measurement. The capacitor is used to smooth the ripple of the current in the measuring circuit.
