Description

Предлагаетс  способ исследовани  нагрева контактов коммутаторных аппаратов.A method for studying the heating of the contacts of switching devices is proposed.

Описываемый способ  вл етс  более совершенным, по сравнению с известными, так как позвол ет искусственно воспроизвести реальные услови  контактов, исключить из исследовани  тепло, выдел емое в самой толще контактов, и получить режим нагрева контактов теплом, выдел емым только в переходном сопротивлении.The described method is more perfect than the known ones, since it allows artificially reproducing the actual conditions of the contacts, eliminating the heat generated in the thickness of the contacts from the study and obtaining the heating mode of the contacts with heat generated only in the transient resistance.

j{:in этой цели между копт ктам закладываютс  миниатюрные нагревательные элементы площадью в несколько дес тков квадратных миллиметров, выполненные из топкого нихрома, намотанного на тонкой слюд ной пластинке с наружными покрыти ми из очень тонкой слюды. Потребл ема  нагревательным элементом мощность контролируетс  амперметром и вольметром и подбираетс  равной мощности , выдел ющейс  в переходномj {: in this purpose, miniature heating elements with an area of several tens of square millimeters, made of top nichrome, wound on a thin mica plate with external coatings of very thin mica, are laid between the copts. The power consumed by the heating element is monitored by an ammeter and a volmeter and is chosen to be equal to the power released in the transition state.

сопротивлении при определенной силе тока и ожидаемом увеличении значени  переходного сопротивлени .resistance at a certain current strength and the expected increase in the value of the transient resistance.

Предлагаемый метод дает хорощие результаты при рабочих поверхност х контактов от 30-40 мм и выще как дл  «поверхностных, так и дл  других видов «линейных контактов.The proposed method gives good results with working contact surfaces from 30–40 mm and higher for both “surface and other types” of linear contacts.

In order to reproduce the expected heating mode of the contacts with heat generated in the transition resistance, a miniature heating element is inserted between the contacts and the power output is set equal to the power lost in the contacts, according to the calculation, npi of the actual operation mode of the device.
