Description
Насто щее изобретение относитс к устройствам дл регулировани напр жени С1ш ронного генератора измен ющейс частоты, питаюн1его асинхронный двигатель буровой установки, в котором в качестве регулирующего элемента нрнменен трансформатор тока с нодмагиичиванием , питающий через вынр митель обмотку возбуждени возбудител генератора.The present invention relates to devices for regulating the voltage C1shnogo generator of variable frequency, powered by an asynchronous motor of a drilling rig, in which as a regulating element nnmenmenen current transformer with nodmagichivaniem, which feeds an exciter generator through a winding generator.
Предлагаемое устройство отличаетс от известных нодобных устройств тем, что трансформатор тока с нодмагничиваннем снабжен трем обмотками управлени , нерва из которых включена нараллельно шунту в цени возбуждени генератора, втора -через вынр митель на выход измерительного трансформатора тока, а треть -к источнику эталонного напр жени , нричем намагничивающа сила нервой управл ющей обмотки действует встречно намагничивающей силе, создаваемой другими управл ющими обмотками. Такое вынолнение устройства позвол ет поддерживать носто нным отнощение напр жени генератора к частоте нри посто нной нагрузке двигател и автоматически измен ть это соотнощение нри изменении нагрузки двигател .The proposed device differs from the known device-like devices in that the current transformer with the magnetisation unit is equipped with three control windings, the nerve of which is connected along the shunt in order to excite the generator, the second through the transmitter at the output of the measuring current transformer, and The magnetizing force of the nerve of the control winding acts counter to the magnetizing force created by the other control windings. Such an implementation of the device makes it possible to maintain a constant ratio of the generator voltage to the frequency at a constant engine load and to automatically change this ratio as the engine load changes.
На чертеже изображена электрическа схема предлагаемого устройства.The drawing shows the electrical circuit of the proposed device.
Обмотка возбуждени / синхронного генератора 2 нитаетс от возбудител 3. Обмотка возбуждени 4 возбудител подключена к независимому источнику посто нного тока (нанример к стартерной батарее) и через выпр митель 5 к трансформатору 6 тока с подмагнич-иванием, включенному в цепь статора генератора. Таким образом осуществл етс компаундирование тока возбуждени возбудител . К обмотке 7 подThe excitation / synchronous generator winding 2 is threaded from the exciter 3. The exciter winding 4 of the exciter is connected to an independent DC source (such as the starter battery) and through the rectifier 5 to the current transformer 6 with magnetic biasing connected to the generator stator circuit. In this way, the excitation current of the driver is compounded. To winding 7 under
