Description
Предлагаетс схема прибора с чувствительным элементом из сплаг .а пермаллой дл измерени слабых магнитных полей.A schematic of the instrument with a permalloy SPM sensing element is proposed for measuring weak magnetic fields.
Особенностью схемы вл етс применение вентил во вторичной цеии трансформатора, в результате чего отпадает необходимость в дополнительной катушке компенсации земного магнитного пол .A feature of the circuit is the use of a valve in the secondary circuit of a transformer, as a result of which there is no need for an additional compensation coil for the earth's magnetic field.
На предлагаемом чертеже приводитс принципиальна электрическа схема прибора.In the proposed drawing, the circuit diagram of the device is given.
Первична обмотка / трансформатора Тр питаетс током частоты 50 гц.The primary winding / transformer Tr is powered by a current frequency of 50 Hz.
В цепи вторичной об.мотки 2 с помощью вентил 3 происходит выир мление неременного тока, в результате чего сердечник 4 трансформатора будет намагничиватьс cpeдни значением выпp JлeиIюгo тока.In the secondary winding circuit 2, a non-current current is extracted by means of the valve 3, as a result of which the transformer core 4 will be magnetised by means of a voltage value of the current.
Если нанравление силовых линий накладываемого на сердечник постороннего магнитного пол (нанрпмер, пол земли) будет противоположным направлению силовых линий магиитного пол , создавае.мого Быпр млепным током, то ири соответствуюш,ем подборе величины переменного напр жени питани трансформатора можно добитьс компенсации действи указанных магнитных полей.If the designation of the power lines imposed on the core of an extraneous magnetic field (nanrpmer, earth floor) is opposite to the direction of the power lines of the magical field, creating a quick current, then by matching the magnitude of the alternating voltage of the transformer you can compensate for the effect of these magnetic fields .
Предмет изобретени Subject invention
Прибор дл измерени слабых магнитных нолей, вынолнеиный по типу трансформатора с разомкнутой магнитной цепью, в которой мешающее магнитное поле (наприме, поле земли) скомпенсировано посто нной составл ющей магнитного потока, отличающийс тем, что ДЛ5 создани этой составл ющей в цепь вторичной (измерительной) об. последовательно с гальванометром включен выпр митель.An instrument for measuring weak magnetic fields, a transformer with a magnetic type with an open magnetic circuit, in which the interfering magnetic field (for example, the earth field) is compensated for by the constant component of the magnetic flux, in which DL5 creates this component in the secondary (measuring) circuit about. A rectifier is connected in series with the galvanometer.
