在去年全国工交战线“质量月”活动中,为了提高产品质量,解决渗漏问题,我厂决定:对库存的和生产线上的YY型移相电容器,全部都要重新进行密封性检查。根据“IEC”标准草案和国内有关资料,75℃加热试漏法是电容器密封性的最后检查方法。我厂按照这种方法,先把试品擦净,缝接地方涂上白土,放在真空罐内加热,试品温度,用芯子插有温度计的电容器确定。在使用这种方法中,发现三个问题:1.不合格的试
In last year’s national working-class warfare “quality month ” activities, in order to improve product quality, to solve the leakage problem, our factory decided: on the inventory and production line YY-type phase-shifting capacitors, all to be re-sealed. According to the “IEC” standard draft and the domestic relevant information, 75 ℃ heating leakage test method is the final inspection of the capacitor sealing. I plant in accordance with this method, the first wipe the test, sew the ground coated with clay, placed in a vacuum tank heating, the test sample temperature, with a core inserted thermistor capacitors to determine. In using this method, three problems were found: 1. Unqualified test
