由于循环油的耐压降低或X线管灯丝接线较长,往往会发生高压绝缘纸筒击穿。现介绍我院在维修过程中所采用的简便方法。一、表面线状击穿先用新的坏钢锯条或小刀,刮清击穿处的碳化物。然后,用环氧树脂加入适量固化剂(乙二胺)调匀,涂在击穿处,等干后即可使用。涂时要求表面光滑,不许有刺状出现,以避免尖端放电。二、击穿面较大而且较深这种击穿光用环氧树脂无法填平。此时
As the circulating oil pressure is reduced or the X-ray tube filaments are longer, a breakdown of the high-voltage insulating paper cylinder tends to occur. Now introduce the simple method that our institute uses in the maintenance process. First, the surface of the line of breakdown with a new bad steel blade or knife, scraping the breakdown of the carbides. Then, add an appropriate amount of curing agent (ethylenediamine) with epoxy resin and mix thoroughly, apply it to the breakdown area, and wait for it to dry before use. When coating, the surface should be smooth and no stinging should occur to avoid tip discharge. Second, the breakdown surface is larger and deeper This breakdown light cannot be filled with epoxy resin. at this time
