Lifting and transportation of transformer main body
2.1 运输要求
Transportation Requirements
2.1.1 充油运输的变压器应先充入合格的变压器绝缘油，油面离油箱顶约100mm下车用英语怎么说高度空间充以干燥氮气，检查有无渗漏现象，箱顶装设的压力表应保持正压力即可。
今年的五年二班 Transformer transported with oil filled should be filled with qualified transformer oil to 100mm oil level from tank cover and the space is filled with dried nitrogen. Check whether there is oil leakage. The pressure gauge on the tank cover keeps positive pressure.
2.1.2 充氮运输的变压器，应充入纯度大于99.9%，露点不高于-40C的纯氮气，并应在油箱上装置充氮设备和压力表，保持油箱内的初始正压力在（0.02~0.03）MPa之间（有载分接开关和本体用U形管连结，同时充氮）。主体运到现场后，主体内的氮气压力应保持正压。
Transformer is filled with nitrogen during transportation. The purity of nitrogen shall b
e more than 99.9% and its dew point 文艺短句≤-40C. There shall be nitrogen filling device and pressure guage mounted on the tank. The initial positive pressure inside the tank shall keep between 0.02 and 0.03MPa (on-load tap changer and main body connected by U-shaped tube filled with nitrogen). At site, the nitrogen pressure inside the body shall keep positive.
