摘要： There is provided a method for electrically energizing and heating a platinum or platinum-alloy composite tube structure having a structure including a first main tube, a second main tube, and a branch tube connecting the first main tube and the second main tube, which prevents a local part of the branch tube from being electrically energized and heated in an excessive or insufficient manner. There is provided a method for electrically energizing and heating a platinum or platinum-alloy composite tube structure having a structure including a first main tube, a second main tube, and a branch tube connecting the first main tube and the second main tube, the method comprising dividing an energizing path for the branch tube into a first energizing path from the first main tube to the branch tube and a second energizing path from the branch tube to the second main tube; and performing energization control for the first energizing path and energization control for the second energizing path independently of each other.
摘要翻译：提供了一种对具有第一主管，第二主管和连接第一主管和第二主管的分支管的结构的铂或铂合金复合管结构进行电激励加热的方法，其防止分支管的局部部分被电力激励并以过度或不足的方式加热。提供了一种对具有包括第一主管，第二主管和连接第一主管和第二主管的分支管的结构的铂或铂合金复合管结构进行电激励和加热的方法，该方法包括将所述支管的通电路径从所述第一主管到所述分支管分成第一通电路径，以及从所述分支管到所述第二主管的第二通电路径; 并且对于第一通电路径进行通电控制，并且彼此独立地执行用于第二通电路径的通电控制。
