Description
Изобретение относитс к устройствам , предназначенным дл определени плотности тока в гальванической ванне, питаемой посто нным током от коллекторного генератора, механического или полупроводникового выпр мител . Дл измерени плотности тока используетс индукционный датчик, действие которого основано на индуктировании переменной составл ющей- посто нного тока, пропорциональной по величине среднеэффективному току.The invention relates to devices for determining the current density in a galvanic bath supplied with direct current from a collector generator, a mechanical or semiconductor rectifier. An inductive sensor is used to measure the current density, which is based on inducing a variable component of a constant current proportional to the magnitude of the average effective current.
Известно устройство дл контрол толщины гальванического покрыти издели в ванне, действующее при помопди индукционных датчиков, питаемых током повышенной частоты.A device for monitoring the thickness of an electroplated coating of a product in a bath is known, which acts upon the help of induction sensors powered by an increased frequency current.
Предлагаемое устройство значительно проще известных и позвол ет определ ть с больщой точностью плотность тока в гальванической ванне путем измерени величины переменной составл ющей питающего пульсирующего тока.The proposed device is much simpler known and allows the current density in a galvanic bath to be determined with greater accuracy by measuring the value of the variable component of the supplying pulsating current.
На фиг. 1 приведен индукционный датчик, представл ющий собой трансформатор тока.FIG. 1 shows an induction sensor, which is a current transformer.
Иа тороидальный сердечник 1 датчика, выполненный из ферромагнитного материала с высокой магнитной проницаемостью, намотана обмотка 2, изолированна от внешнего воздействи кожухом 3.The toroidal core 1 of the sensor, made of a ferromagnetic material with high magnetic permeability, is wound around a winding 2 and insulated from external influences by a casing 3.
Индукционный датчик помеи1аетс в электролит в непосредственной близости от деталей и может находитьс в ванне длительное врем , что позвол ет подключнть его к автоматическимрегулируюнитThe induction sensor is immersed in the electrolyte in the immediate vicinity of the parts and can stay in the bath for a long time, which allows it to be connected to an automatic regulator.
устройствам, которые автоматически поддерживают заданную плотность тока или автоматически сигнализируют о недопустимых отклонени х плотности тока от заданной. Индукционные датчики предусматриваютс двух размеров:devices that automatically maintain a given current density or automatically signal an unacceptable deviation of current density from a given one. Induction sensors are available in two sizes:
а)на тороиде диаметром менее 10 мм дл измерени местной плотности тока;a) on a toroid with a diameter less than 10 mm to measure the local current density;
б)на узком большом тороиде, с сечением отверсти 100 см дл измерени средней плотности тока.b) on a narrow large toroid, with a cross-section of a hole of 100 cm to measure the average current density.
Иа фиг. 2 показан индукционный датчик 4, погруженный в гальваническую ванну 5 и подключенный кFIG. 2 shows an induction sensor 4 immersed in a galvanic bath 5 and connected to
