The problem of higher oil temperater for the cooling system of the rectifier transformer, the transform plan of the cooling system of the rectifier transforner is presented.
针对整流变压器冷却系统运行存在的油温偏高问题，介绍了整流变压器冷却系统改造方案。
2
When rectifier transformer is matched with gas relay, "light gas" signal and "critical oil temperature" signal are connected in parallel;
当整流变压器配用瓦斯继电器时，“轻瓦斯”讯号和“临界油温”讯号并联；
3
The cooling oil level, and the recommended levels shall be clearly visible during normal operation of the rectifier via the external sight glass.
