Description
Изобретение относитс к способам iiiiMcpeinin посто нного тока без разpiiiiia цепи, В известных устройствах рода H;iMcpoHiie ocyHieсгвл етс с помощью п: мерптельной обмотки, взаимодействующей с MartinTiibiM полем измер емого тока и подключенной к стрелочному индикатору , например к баллистическому гальванометру.The invention relates to methods for iiiiMcpeinin DC without razpiiiiia circuit, In the known devices of the genus H; iMcpoHiie ocyHi is connected using n: merptelnoy winding, interacting with MartinTiibiM field of the measured current and connected to a dial gauge, for example to a ballistic galvanometer
Дл упрощени измерительного устройства предлагаетс , согласно изобретению, измерительную обмотку расположить на двух полукольцах нз немагнитного материала, выполненных в виде клещей, охватывающих проводник с измер емым током, а в качестве индикатора использовать флюксметр. Предлагаемый способ измерени по сн етс фиг. 1 и 2. На фиг. 1 показано устройство клещей с измерительной обмоткой; на фиг. 2 - схема измерительного устройства.In order to simplify the measuring device, according to the invention, it is proposed to place the measuring winding on two half-rings of a non-magnetic material made in the form of ticks covering a conductor with measured current, and using a fluxmeter as an indicator. The proposed measurement method is illustrated in FIG. 1 and 2. In FIG. 1 shows a pincer device with a measuring winding; in fig. 2 - diagram of the measuring device.
Магнитные клещи состо т из двух полуколец / и 2, изготовленных из немагнитного электроизол ционного материала, например гетинакса,Magnetic mites consist of two half-rings / and 2, made of a non-magnetic electrically insulating material, such as getinax,
текстолита, дерева и т. п. Руко тки 3 служат дл раскрыти клещей при установке их на проводник с током. Измерительна обмотка 4 разделена на две части и расположена на полукольцах / и 2 клещей. Флюксметр 5 соединен с измерительной катушкой соединительными проводами 6.PCB, wood, etc. Handles 3 are used to open ticks when installed on a conductor with a current. The measuring winding 4 is divided into two parts and located on the half rings / and 2 ticks. Fluxmeter 5 is connected to the measuring coil by connecting wires 6.
При измерении полукольца клещей развод т, охватывают ими проводник с током и смыкают вокруг проводника. Стрелка флюксметра при этом отклон етс , а угол поворота стрелки пропорционален силе тока в проводнике.When measuring the semiring, the tongs are diluted, cover the current carrying conductor with them, and close them around the conductor. The arrow of the fluxmeter is thus deflected, and the angle of rotation of the arrow is proportional to the strength of the current in the conductor.
При сн тии клещей с проводника стрелка отклон етс в обратную сторону , поэтому отсчет производ т до сн ти клещей.When removing ticks from a conductor, the shooter deviates in the opposite direction, therefore, counting is done before removing ticks.
