Abstract: Изобретение относится к области электротехники, в частности к разрядникам для грозозащиты элементов электрооборудования или линии электропередачи. Технический результат заключается в одновременном увеличении прочности, надежности и технологичности разрядника, а также в увеличении диапазона токов молнии, которые он может выдержать без повреждения. Достигается благодаря нескольким факторам, в числе которых находится армирование более протяженными электродами изоляционного тела, а также большая масса и теплоёмкость электродов, что способствуют дополнительному отводу тепла от канала разряда, гашению дуги и уменьшению тепловой нагрузки на изоляцию разрядника. Надежность и технологичность обеспечивается выступающими наружу из изоляционного тела частями электродов, что позволяет изготавливать изоляционное тело в одну стадию благодаря возможности крепления электродов в форме, что также повышает прочность изоляционного тела ввиду отсутствия в нем швов и соединений. Кроме того, выступающие электроды повышают надежность разрядника, поскольку при чрезмерном повышении разрядного перенапряжения разряд может начаться на внешних частях электродов, предохраняя разрядные камеры в изоляционном теле от выгорания. 4 н. и 6 з.п. ф-лы, 5 ил.
