Description

Предметом насто щего авторского свидетельства  вл етс  устройство дл  измерени  температуры  кор  генератора посто нного тока при помощи меднозакисного выпр мител , помещенного в паз машины.The subject of this author's certificate is a device for measuring the temperature of the core of the generator of direct current using a copper oxide rectifier placed in the groove of the machine.

Сущность изобретени , заключающа с  в особой схеме электрических соединений указанного выпр мител , источника электрического тока, электричес1 ого измерительного прибора и катущки самоиндукции, устран ющей вли ние пульсирующей э. д. с., по сн етс  чертежом, на котором изображена принципиальна  электрическа  схема предлагаемого устройства .The invention consists in a special circuit of electrical connections of said rectifier, source of electric current, electric measuring device and self-induction coil, eliminating the influence of pulsating energy. d. s., illustrated in the drawing, which shows a circuit diagram of the device.

Заложенный в паз  кор  мащины меднозакисный выпр митель С одним концом присоединен к коллекторной пластине Р, а другим заземлен (фактически присоединен к заземленному корпусу  кор ). Между вспомогательной щеткой контролируемой мащины и заземленным валом включены последовательно реактивна  катущка L с очень больщой самоиндукцией, магнитоэлектрический миллиамперметр А и источник Е посто нного тока (гальванические элементы илиA copper-oxide rectifier laid into the groove of the bark box is connected at one end to the collector plate P, and the other is grounded (actually connected to the grounded core case). Between the auxiliary brush of the monitored mashiny and the grounded shaft are connected in series the reactive coil L with a very large self-induction, a magnetoelectric milliammeter A and a source of direct current E (galvanic cells or

аккумул тор), ток от которого должен протекать через выпр митель С в непровод щем направлении.battery), the current from which must flow through rectifier C in a non-conductive direction.

Протекающий через миллиамперметр А ток i состоит из двух составл ющих- посто нной ig и переменной синусоидальной г (вызванной наличием синусоидальной э. д. с. между коллекторной пластиной Р и щеткой), котора  не вли ет на показани  миллиамперметра, но усиливает нагрев выпр мител  О.The current i flowing through milliammeter A consists of two components, a constant ig and a variable sinusoidal r (caused by the presence of a sinusoidal e.d. ABOUT.

Дл  уменьщени  i включаетс  реактивна  катущка L, котора  должна удовлетвор ть условию, чтобы полное падение напр жени  в выпр мителе С (от i -и от не превыщало 5 V; иначе возможно пробитие выпр мител .To decrease i, a reactive coil L is turned on, which must satisfy the condition that the total voltage drop in the rectifier C (from i to and from does not exceed 5 V; otherwise, the rectifier may break through.

Дл  предохранени  изол ции  кор  в случае короткого замыкани  нужно включить между выпр мителем С и корпусом небольщой предохранитель, рассчитанный на несколько дес тков миллиампер.In order to protect the insulation of the core in the event of a short circuit, a small fuse designed for several tens of milliamperes must be inserted between rectifier C and the case.
