牵引变压器的气候环境适应性设计浅析

Traction transformer of climate adaptability design analysis

高海拔地区具有气压低,气温低等气候特点。此环境将对牵引变压器所用材料及冷却介质产生影响;低气压使牵引变压器的外部电气绝缘下降;牵引变压器温升增加,对此,阐述了在进行牵引变压器设计时,其环境适应性所需的设计要求。

The climate characteristic of the plateau region is low pressure and low temperature. In this situation, there are three elements that will affect the design of the traction transformer （ shot for TT） ： 1 ） the characteristic of the materials and the cooling medium will be changed ; 2） the electrical insulation will be descended ; 3 ） the temperature rise of Tr will be increased. So, in this paper, the design requirement of the environmental adaptability of TT will he expounded.
