摘要
干式空心并联电抗器在运行中曾发生多起烧损事故。人们在分析这些事故中普遍认为电抗器包封进水是导致其事故的主要原因,并对此采取了许多措施,然而运行的结果是事故并没有因此而减少。对此,作者对包封进水对电抗器可靠性的影响进行了试验研究。文章介绍了进行该试验研究所用试品、试验方法、试验过程及结果,并对试验前后的结果进行了对比分析。试验结果认为包封进水对电抗器可靠性有影响,但不是主要因素。建议进一步进行机理研究,并有针对地采取措施。
The burn - out accident occurred several times ha operation of dry type hollow shunt reactor. The major mason of these accidents for people thinking generally is watered reactor sealing, and a lot of measures for this were adopted, but the accidents do not decrease therefore. This paper studied the influence of watered sealing on reactor reliability. The testing sample, method, course and results for this testhag research were introduced, and the results before and after the testing were analyzed and contrasted. The test results show that the influence of watered sealing is not major factor on reactor reliability. It is suggested that to carry out mechanism research further to adopt measures for improving reactor reliability.
