低能量下X射线辐射对变压器油影响

Study of the Low Energy X-ray Impact to the Transformer Oil

针对利用X射线数字成像技术对电力变压器进行透照检测时可能造成变压器绝缘油绝缘性能的变化的问题,提出了定X射线能量对变压器油进行照射研究。该研究利用便携式高频X射线机分别对带电压和不带电压的变压器油进行定能量和定时间的照射,实验结果表明,在低能量下,X射线的辐射对变压器油的击穿电压,带电倾向性和介质损耗因数没有影响。

In order to clearly understand the impact of X - rays on the transformer oil, It is proposed a research of using given energy X - ray to irradiate the transformer oil in this paper. The content of the study is to irradiate the applied voltage and no voltage transformer oil respectively for given energy and given time by portable high frequency X -ray generator. Experimental results show that low energy X - ray has no effect on the breakdown voltage, charging tendency, and the dielectric loss factor of transformer oil.
