Abstract

FIELD: electrothermics; power supply to direct-heating resistance furnaces, such as graphitizing furnaces, and other heavy-current devices. SUBSTANCE: current lead for heavy-current electrothermal devices has carbon electrode and current-carrying metal bus joined to the former. Joint is made by means of additionally introduced electric contact plugs. Plugs are welded into carbon electrode by electric arc welding. Contact plugs are provided with expansion devices and opposing ends of the latter are joined to current-conducting metal bus. EFFECT: reduced electrical resistance at joint and reduced power requirement. 1 cl, 2 dwg

Использование: изобретение относится к электротермии и предназначено для электропитания печей сопротивления прямого нагрева, таких, например, как печи графитации и других высокоамперных устройств. Цель: снижение электросопротивления в зоне сопряжения и снижения расхода электроэнергии. Сущность изобретения: токоввод электротермических высокоамперных устройств включает углеродный электрод и сопряженную с ним токоподводящую металлическую шину. Сопряжение выполнено посредством дополнительно введенных электроконтактных пробок. Пробки вварены в углеродный электрод злектродуговой сваркой. Электроконтактные пробки снабжены компенсаторами, а противоположные концы компенсаторов соединены с токоподводящей металлической шиной. 1 с.п.ф-лы, 2 ил.Usage: the invention relates to electrothermics and is intended for power supply of direct heating resistance furnaces, such as, for example, graphitization furnaces and other high-ampere devices. Goal: reduce electrical resistance in the interface zone and reduce energy consumption. The inventive current lead of electrothermal high-ampere devices includes a carbon electrode and a current-conducting metal bus connected to it. Pairing is carried out by means of additionally introduced contact plugs. The plugs are welded into the carbon electrode by electric arc welding. Contact plugs are equipped with compensators, and the opposite ends of the compensators are connected to a current-carrying metal bus. 1 s.p. f-ly, 2 ill.
