Self - cooling and forced air cooling
自冷与强迫风冷
Measuring methods of thermal characteristic for forced air cooling of electronic equipment
电子设备强迫风冷热特性测试方法
The transformers can be cooled by air naturally ( an ) or forced air cooling ( af ) . cooled by an , transformers can oprerate up to 100 % of its rated output . in af mode , output can be increased by 40 50 % of its rated output
风冷系统：变压器在自然冷却条件（ an ）下，可在额定容量下长期安全运行，强迫空气冷却（ af ）时，变压器按容量大小相同，可增容40 ~ 50 % 。
3 . we do short circuit analysis upon multiple magnetic circuit transformers by use of steady non - linear analysis and get the leakage reactance respectively between high voltage and high voltage 、 high voltage and low voltage 、 two high voltage and low voltage 、 low voltage and high voltage and low voltage and two high voltage . what ’ s more , we do finite element analysis upon the temperature field of transformers and according to its distribution we get the wind speed to forced air cooling
3 、采用稳态非线性分析法对多磁路变压器进行短路阻抗计算,利用能量法计算出变压器高压与高压、高压与低压、两高压与低压、低压与高压以及低压与两高压之间的漏感;对变压器的温度场进行有限元分析,确定温度场分布情况。
