Изобретение относитс к области измерительной техники.The invention relates to the field of measurement technology.
Известны устройства дл измерепи температуры обмоток роторов синхронных электрических машин с использованием в качестве термодатчика самой обмотки ротора, включенной в измерительную схему с показывающим прибором.Devices are known for measuring the temperature of the windings of the rotors of synchronous electric machines using the rotor winding itself included in the measurement circuit with the indicating device as a thermal sensor.
Однако показани известных устройств недостаточно точны из-за температурной погрешности в показывающем приборе.However, the readings of the known devices are not accurate enough due to the temperature error in the indicating device.
Дл повышени точности измерени в предлагаемом устройстве в качестве показывающего прибора использован логометр, одна рамка которого подключена к выпр мителю схемы непосредственно, а друга рамка через добавочные резисторы и щетки подсоединена к кольцам ротора синхронной машины.To improve the measurement accuracy in the proposed device, a logometer is used as an indicating instrument, one frame of which is connected to the circuit rectifier directly, and the other frame is connected via resistors and brushes to the rotor rings of the synchronous machine.
На чертеже показано онисываемое устройство .The drawing shows the onisable device.
Обмотка 1 ротора через кольцо 2 ротора подключена к первичной обмотке 3 трансформатора 4 посто нного тока вторична цепь 5 которого св зана через трансформатор 6 переменного тока с выпр мителем 7.The rotor winding 1 through the rotor ring 2 is connected to the primary winding 3 of the direct current transformer 4 whose secondary circuit 5 is connected through an alternating current transformer 6 with a rectifier 7.
Рамка 8 логометра 9 подключена к выпр мителю 7 непосредственно, а рамка 10 - через добавочные резисторы И и 12 и щетки подсоединена к кольцам 2, 13 ротора.Frame 8 of the meter 9 is connected to the rectifier 7 directly, and frame 10 through additional resistors And and 12 and brushes connected to the rings 2, 13 of the rotor.
Предложенна схема устройства не требует температурной компенсации, так как рамка 8 логометра 9 подключена к щеткам ротора через добавочные резисторы 11 и 12.The proposed scheme of the device does not require temperature compensation, since the frame 8 of the meter 9 is connected to the rotor brushes through additional resistors 11 and 12.
Предмет изобретени Subject invention
Устройство дл измерени температуры обмоток роторов синхронных электрических машин с использованием в качестве термодатчика самой обмотки ротора, содержащее трансформатор посто нного тока, первична обмотка которого подключена к термодатчику, а его вторична цепь при помощи трансформатора переменного тока индуктивно св зана с выпр мителем , к которому присоединен показывающий прибор, отличающеес тем, что, с целью -повышени точности измерени , в качестве показывающего прибора использован логометр, одна рамка которого подключена к выпр мителю, а друга - через добавочные резисторы и щетки подсоединена к кольцам ротора синхронной машины.A device for measuring the temperature of the rotor windings of synchronous electric machines using the rotor winding itself as a thermal sensor, which contains a DC transformer, the primary winding of which is connected to the thermal sensor, and its secondary circuit is inductively connected to the rectifier to which it is connected indicating device, characterized in that, in order to increase the measurement accuracy, a logometer is used as a indicating device, one frame of which is connected on to the rectifier, and the other through additional resistors and brushes connected to the rotor rings of the synchronous machine.
