Abstract

Способ откачки и герметизации в вакуумной печи вакуумных дугогасительных камер, собранных из узлов, предварительно спаянных первым припоем и имеющих один или несколько незапаянных швов между этими узлами с заложенным в них вторым припоем с более низкой, чем у первого, температурой плавления, содержащий последовательность операций: откачки объема печи, нагрев до температуры обезгаживания, выдержка при этой температуре, кратковременный нагрев и выдержка при температуре плавления второго припоя, снятие нагрева, герметизация швов и остывание печи, отличающийся тем, что после операции откачки объема печи проводится дополнительная операция выдержки при температуре не более 100°С, длительностью, достаточной для откачки газа из внутреннего объема вакуумных камер через незапаянные швы.A method of pumping and sealing in a vacuum furnace vacuum arcing chambers assembled from nodes previously soldered by the first solder and having one or more unsealed seams between these nodes with a second solder embedded in them with a lower melting temperature than the first one, containing the sequence of operations: evacuation of the furnace volume, heating to the degassing temperature, holding at this temperature, short-term heating and holding at the melting temperature of the second solder, removing heat, sealing the joints and cooling furnace, characterized in that after the operation of pumping the volume of the furnace, an additional operation of soaking is carried out at a temperature of not more than 100 ° C, with a duration sufficient to pump gas from the internal volume of the vacuum chambers through unsealed seams.
