互感器产品顶油方式的改进
发布时间:2018-10-21 18:40
【摘要】:正1前言油浸互感器产品(包括电流、电压及组合互感器)在真空注油后,要对膨胀器进行顶油操作,以达到规定高度的要求。由于现行的顶油方式是在常压下对膨胀器进行顶油的,在顶油过程中,膨胀器波纹内可能会残存一定的气泡,这些气泡必须在膨胀器高度超出自然高度后,采用人工方式通过在不同方位按压、振动膨胀器来排出其中的残存气泡。但这种
[Abstract]:Oil immersed transformer products (including current, voltage and combination transformer) should be operated on top of the expander after vacuum oil injection to meet the requirements of the specified height. Because the current top oil method is to top the expander under atmospheric pressure, during the top oil process, there may be some bubbles remaining in the expander ripple, and these bubbles must be higher than the natural height of the expander. The residual bubbles are discharged manually by pressing the vibratory expander in different directions. But this.
