Description

В известных устройствах дл  измерени  температуры контактной площадки электрического контакта при протекании через него тока не предусмотрена возможность суммировани  токов от термоэ.д.с, что понижает чувствительность приборов и точность производимых ими измерений .In the known devices for measuring the temperature of the contact pad of an electrical contact when current flows through it, it is not possible to sum up the currents from thermal emf, which reduces the sensitivity of the instruments and the accuracy of the measurements they make.

Предлагаемое устройство обеспечивает компенсацию токов, возникающих от падени  напр жени  на контактах и от индуктированных э. д. с.The proposed device provides compensation for currents arising from the voltage drop at the contacts and from the induced voltage. d.

Между исследуемыми контактами, выполненными из одного материала , помещаетс  токопровод щий элемент, изготовленный из другого материала и соединенный с одним из вводов электроизмерительного прибора, второй ввод которого подключен к движку делител , соединенного с исследуемыми контактами.A conductive element made of another material and connected to one of the inputs of an electrical measuring device is placed between the contacts under study made of the same material, the second input of which is connected to a divider engine connected to the contacts under study.

На чертеже изображена принципиальна  схема описываемого устройства .The drawing shows a schematic diagram of the described device.

Устройство содержит исследуемые контакты 1 н 2, токопровод щий элемент 5, электроизмерительный прибор 4 и делитель 5. Исследуемые контакты изготовлены из одного материала, например меди или стали, и представл ют собой стержни с торцами, обработанными по сфере. Токонровод щий элемент выполнен в виде пластины из другого материала , например никел , и помещен между исследуемыми контактами. Токопровод щий элемент соединен с одним из вводов электроизмерительного прибора, который вторым вводом подключен к движку Делител , соединенного, в свою очередь, с исследуемыми контактами.The device contains the investigated contacts 1 n 2, the conductive element 5, the electrical measuring device 4 and the divider 5. The investigated contacts are made of the same material, for example copper or steel, and are rods with ends machined on a sphere. The current-conducting element is made in the form of a plate made of another material, for example nickel, and placed between the contacts under study. The conductive element is connected to one of the inputs of the electrical measuring device, which is connected to the divider engine by the second input, which, in turn, is connected to the contacts under study.

Токи, текущие через электроизмерительный прибор и возникающие в результате падени  напр жени  на контактах и от индуктированных э. д. с., компенсируютс  выбором положени  проводников и установки движка делител , а токи, пропорциональные термоэ.д.с., суммируютс  в приборе.The currents flowing through the electrical measuring device and resulting from the voltage drop at the contacts and from the induced e. D. s., are compensated by the choice of the position of the conductors and the installation of the divider engine, and the currents proportional to the thermal emf are summed in the device.
