随着电气设备的增多,绝缘油耐电强度的试验工作日渐繁重。采用手动操作,费时且升压速度不均匀,影响试验质量。为改善这种状况,我厂制作组装了“三杯油自动耐压试验装置”。多年实践结果表明:该试验装置在工作时,接通电源即可自动操作,不要人监视;试验数据分散性小,提高了准确度;试验时间短,试验过程中无需人工拨散 With the increase of electrical equipment, the test of electrical insulation strength of oil has become increasingly heavy. The use of manual operation, time-consuming and uneven speed boost, affecting the quality of the test. To improve this situation, I plant assembly “three cups of oil pressure test device.” Years of practical results show that: the test device at work, the power can be automatically switched on, do not want people to monitor; test data dispersion is small, improve the accuracy; test time is short, the test process without artificial dispersion
