保山干式变压器：保山干式变压器区域划分的一般原则

保山干式变压器区域划分的一般原则 　　
一般以高压线圈为基础来划分区域，低压线圈的区域与高压线圈的区域是相对应的，即区域数和高压线圈相等。两个线圈相对应的区域高度应尽量相等，且在区域内沿高度方向安匝分布尽量均匀。
一个区域的主漏磁空道及线段轴向尺寸、油道尽量相等。
低压各区域中的匝数百分数，应根据相对应的高压各区域中的百分数而决定，其百分数的数值相差越小越好，否则安匝分布的不平衡性就大。
对称的线圈可按一半计算；线圈由两个支路并联时，可合并成一个支路计算。

General principles of the transformer zoning

Usually divided areas on the basis of the high voltage coil, the low pressure region of the coil and the high voltage coil region is the corresponding, i.e. equal to the number of regions and the high voltage coil. Two coils an area corresponding height should be equal, as far as possible and distributed as evenly as possible in the region along the height Fangxiang An turns.
A regional main drain the magnetic Kongdao and the segment axial dimension, the oil channel as equal.
The percentage of the number of turns of the respective regions of the low pressure, and should be determined according to the percentage of the corresponding high-pressure region, the percentage of the numerical difference between the smaller the better, otherwise the imbalance of the distribution of ampere turns.
Symmetrical coil may be calculated as half; coil is composed of two branches in parallel, can be combined into one branch.
