Изобретение относитс к электроизмерительной- технике, в частности к: устройствам дл измерени диэлектрической йроницаемости и тангенса угла диэлектрических потерь испытуемых образцов твердых электроизол ционных материалов. The invention relates to an electrical measuring technique, in particular, to: devices for measuring the dielectric constant and the tangent of the dielectric loss angle of the tested samples of solid electrical insulating materials.
Известны измерительные конденсаторы , содержащие электроды типа точечных держателей ГО.Known measuring capacitors containing electrodes such as point holders GO.
Недостатком этих ко щенсаторов вл етс , наличие погрешности измерени , обусловленной вли нием краевого эффекта и паразитных емкостей.The disadvantage of these co-sensors is the presence of measurement error due to the influence of the edge effect and parasitic capacitances.
Наиболее близким по технической сущности к предлагаемому вл етс измерительный конденсатор, содержащий плоские неподвижный и подвижный электроды и соединенный с подвижнь1м электродом микрометрический виит с головкой. Между основанием и повоpoTHbiM кольцом головки последова-. .т тельно установлены калиброваннЬй упругий элемент и шарик, фиксируемыйThe closest in technical essence to the present invention is a measuring capacitor containing flat stationary and movable electrodes and a micrometer viit connected to a mobile electrode with a head. Between the base and the thrust ring head sequence-. . The calibrated elastic element and the ball fixed

Недостатком этого измерительного конденсатора. вл етс отсутствие возможности регулировки и установки требуемого удельного давлени на испытуемый образец, что особенно существенно при испытани х образцов без электродов на рабочих поверхност х . Наличие воздушных промежутков между электродами измерительного конденсатора и.рабочими поверхност ми испытуемого образца приводит к значительной погрешности измерени его &М1{остн и, следовательно , к погрешност м измерений диэлектрической проницаемости и тангенса угла диэлект трических потерь исследуемого материала .The disadvantage of this measuring capacitor. It is not possible to adjust and set the required specific pressure on the test sample, which is especially significant when testing samples without electrodes on the working surfaces. The presence of air gaps between the electrodes of the measuring capacitor and the working surfaces of the test sample leads to a significant error in measuring it & M1 {and, consequently, to errors in measuring the dielectric constant and the tangent of the dielectric loss angle of the material under study.
Цель изобретени - повышение точности измерени .The purpose of the invention is to improve the measurement accuracy.
