Abstract

FIELD: electrical engineering; off-load switching of high-power and high- frequency circuits. SUBSTANCE: movable contact of switch is make in the form of hollow flexible cylinder of thin sheet made of high-conductance, heat-resistant metal, such as molybdenum, coiled into multilayer spiral at pitch equal to sheet width; contact is loosely joined with terminal lead over inner surface of spherically rounded-off hole in cylindrical conductor of lead or directly over external spherically rounded-off surface of lead (conductor) with guaranteed gap equal to half-sum of tolerated diameters of mating surfaces of lead (conductor) and movable contact. EFFECT: improved current-carrying capacity and electric strength, improved stability of electrical characteristics during long-time switching operations, improved operating reliability under severe mechanical and environmental conditions. 5 dwg

Изобретение относится к конструкции высоковольтного вакуумного переключателя, предназначенного для коммутации без нагрузки мощных высокочастотных цепей. Достигаемый технический результат - повышение токопропускной способности и электропрочности, обеспечение стабильности электрических параметров при длительной коммутации и надежности работы в условиях воздействия жестких механических и климатических нагрузок. Сущность изобретения состоит в выполнении подвижного контакта переключателя в форме полого упругого цилиндра из свернутой в многослойную спираль тонкой ленты из немагнитного высокопроводящего термоупругого металла, например молибдена, причем шаг спирали выполнен равным толщине ленты, а контакт сочленен подвижно с выводом по внутренней поверхности сферически скругленного отверстия в цилиндрическом токопроводнике вывода, либо непосредственно по внешней сферической скругленной поверхности вывода (токопроводника) с гарантированным зазором, равным полусумме допусков на диаметры сопрягаемых поверхностей вывода (токопроводника) и подвижного контакта.The invention relates to the design of a high-voltage vacuum switch designed for switching without load powerful high-frequency circuits. Achievable technical result is an increase in current transmission capacity and electric strength, ensuring the stability of electrical parameters during long-term switching and reliability under conditions of exposure to severe mechanical and climatic loads. The essence of the invention consists in making a movable contact of a switch in the form of a hollow elastic cylinder made of a thin tape of a nonmagnetic highly conductive thermoelastic metal folded into a multilayer spiral, for example molybdenum, the spiral pitch being made equal to the thickness of the tape, and the contact is movably connected with the output on the inner surface of a spherically rounded hole in a cylindrical output conductor, or directly along the external spherical rounded surface of the output (current conductor) with a guaranteed Azores, equal to half the sum of the tolerances on the diameters of the mating surfaces of the output (tokoprovodnika) and the movable contact.
