The calculation method of the coil temperature rise in SF6 gas insulated transformer under nature gas circulation is introduced. The effects of power loss and heat dissipation on the coil temperature rise are also discussed in this paper. 本文分析了自冷式SF6气体绝缘变压器线圈温升的计算方法,并对变压器功率损耗与散热情况对线圈温升的影响进行了讨论。
The electromagnetic pressure produced by the counteract of magnetic field in coil and the eddy current in liquid metal is mainly determined by the magnetic flux density on the surface and its dissipation in the liquid metal. 在分析液态金属电磁成形理论模型的基础上确认:作用在液态金属表面的电磁压力和加热密度主要取决于其表面上磁场的大小以及磁场在液态金属中的分布规律。
