Description
Дл измерени температуры нагрева обмоток электрических машин, в частности т говых двигателей электровоза, по изменению электрического сонротивлеии этих обмоток иримеи ют устройства, содержащие измерительный прибор по типу логометра, на рамки которого поданы падени напр жений:на контролируемой обмотке электрической машины и иа включенном последовательно с нею посто нном сопротивлении.To measure the heating temperature of the windings of electric machines, in particular, traction motors of an electric locomotive, by changing the electrical resistance of these windings, devices containing a measuring instrument, like a meter, are applied to the framework: voltage drops are monitored on the controlled winding of the electric machine and connected in series with her constant resistance.
Предлагаемое устройство более совершенио по сравнению с известными устройствами подобного типа, так как в нем устранено вли ние иа прибор резких колебаний тока при переходных процессах в электрической машине.The proposed device is more sophisticated than the known devices of this type, since it eliminates the influence of the device on sharp current oscillations during transients in an electric machine.
Это достигаетс тем, что в цепь одной из рамок прибора включены конденсатор и катушка индуктивности.This is achieved by including a capacitor and an inductor in the circuit of one of the instrument frames.
На чертеже изображена электрическа схема предлагаемого устройства .The drawing shows the electrical circuit of the proposed device.
Устройство содержит прибор по типу логометра, на одну из рамок 1 которого подаетс падение напр жени иа обмотке электрической машины 2 (например, на обмотке дополнительных полюсов), а иа другую 3 падение напр жени на дополиителы-юм посто нном сопротивлении (шунте) 4, включенном последовательно с этой обмоткой.The device contains a device as a logometer, on one of the frames 1 of which a voltage drop is applied to the winding of the electric machine 2 (for example, on the winding of additional poles), and the other 3 voltage drop on additional polarity (shunt) 4, connected in series with this winding.
Дл устранени вли ни резких колебаний тока при переходных процессах в двигателе в цепь одной из рамок прибора включены емкость 5 и индуктивность 6.To eliminate the effect of sharp current oscillations during transients in a motor, capacitance 5 and inductance 6 are included in the circuit of one of the instrument frames.
