Изобретение относитс к электротех- , нике, а именно служит дл нахождени важной динамической характеристики электромагнитных элементов посто нного тока - динамической электромагнитной (т говой) характеристики при отпускании шунтированием обмотки возбуждени ..The invention relates to electrical engineering, namely, it serves to find an important dynamic characteristic of the electromagnetic elements of a direct current — a dynamic electromagnetic (traction) characteristic when released by shunting the field winding.
Известно устройство дл испытани реле в динамическом режиме, состо ™ щее из блоков усилител , сн ти импульсов , измерител времени и бесконтактного реле. Сн тие характеристик осуществл етс плавный изменением тока в обмотке возбуждени электромагнитного элемента 1.A device for testing relays in dynamic mode is known, consisting of amplifier blocks, pulse pickup, a time meter and a contactless relay. The removal of the characteristics is carried out by continuously varying the current in the excitation winding of the electromagnetic element 1.
Однако реальный закон изменени тока в обмотке возбуждени электромагнитного элемента при отпускании замен етс плавным (статическш л), что приводит к недостаточной точности и надежности испытани электромагнитных реле.However, the actual law of change of current in the excitation winding of an electromagnetic element when released is replaced by a smooth (static), which leads to a lack of accuracy and reliability of testing electromagnetic relays.
Известно также устройство дл измерени подъемной силы магнита, состо щее из блока намагничивани 4р змагнйчйва-It is also known a device for measuring the lifting force of a magnet, consisting of a magnetizing unit 4p zmagnichyva-
ни ) и измерительного механизма. При индивидуальных измерени х электромагнитной силы производитс измерение соответствующего зазора 2nor) and measuring mechanism. With individual measurements of electromagnetic force, an appropriate gap 2 is measured.
Однако измерение электромагнитной силы возможке только при определенном интервале ее изменени . При небольших значени х электромагнитной силы ее измерение происходит с особенно большой погрешностью из-за вли ни трени . Еди10 ничные измерени электромагнитной силы в статическом режиме недостаточно точны ,However, the measurement of electromagnetic force is possible only at a certain interval of its change. With small values of electromagnetic force, its measurement occurs with a particularly large error due to the influence of friction. Uniform measurements of electromagnetic force in static mode are not accurate enough.
Наиболее близким к предлагаемому вл етс устройство дл испытани элект15 ромагнитов посто нного тока, состо щее из электромагнитного элемента посто нного тока, датчика положени кор , Bti- числительной схемы и электроннолучевого осциллографа Closest to the present invention is a device for testing electromagnetics of direct current, consisting of an electromagnetic element of direct current, a core position sensor, a Bti-numeral circuit, and an electron-beam oscilloscope
