用于炼油、化工等企业的防爆高压电动机经常发生崩烧事故,影响了生产安全,造成经济损失。文章通过对因果树图中的9条末端因素进行分析,确认主要原因是由于引线绝缘层损伤。针对这一原因,找出了相应的对策,并对其效果进行了验证。
The high- voltage Ex motors used in oil refining or chemical plants are often bumt and these accidents have very serious influence on the security in the production and bring about economic loss. With a cause - effect tree graph, 9 main factors involved in this accident are worked out. By analysis one by one, the cause of the accident is confirmed, damage of the insulating layer of the leading wire. Against this cause, some measures are taken; furthermore, the result is verified.
