电仪施工方案Scheme of electric and instrumental construcation 变压器安装 Tranformer installation 设备到达现场后的检查及保养 Checkings and mentainance of equipment after arrival 充氮运输的变压器油箱内氮气压力应在0.01～0.03Mpa之间，达不到此要求，则进一步检查变压器是否受潮；如受潮应与厂家联系，并必须在安装前对变压器进行干燥处理，并做好检查及处理记录； If the transformers are carried by means of niteogen-filled transportation, the pressure inside its oil tank should remain stable between 0.01 to 0.03 Mpa. Otherwise further humidity ckecking is needed. If the transformer is humidified, it is necessary to connect the supplier. Moreover, drying work, checking and record-making must be carried out before installation. 检查冲击记录仪判定变压器在运输装卸过程中是否受到过冲击； Make it clear wether the transformer has been stricked or heat in transit and in unloading process by checking records on the stricking instrument. 到达现场后的附件应齐全，无锈蚀及机械损伤，密封应良好；充油套管应无渗油，油位正常；瓷件及绝缘件应无裂纹或破损； All auxiliary components arrived should be in readiness and intergratedly packed without erosion or physical damages. There should not be leakage at oilfeed pipe sets; 将附件按要求清洗干净并分类保管； All components should be cleaned as required and store in series; 到达现场的绝缘油，按照标准规定进行抽样测试，避免不同牌号的绝缘油混用，将油桶的油储藏于密封清洁专用油箱； Sampling of insulatin oil arrived should be recommended in case that oil of different types are to be mixed. The oil should be stored into special clean oil tanks; 变压器如三个月内不进行安装时，必须采取以下措施： The following measures must be taken provided that the transformers are not supposed to be installed within three months: 充氮运输的变压器必须每天检查一次氮气压力，如氮气压力低于0.01Mpa，应按厂家说明书补氮； Daily nitrogen pressure check is needed for the transformers. Additional reefed should be processed once the level is below 0.01Mpa; 带油运输的变压器应检查油箱密封情况，测量油的绝缘强度和测量绕组的绝缘值，上部抽真空，充以0.01～0.03Mpa的纯氮气，并每天检查一次氮气压力；Oiltightness of the tanks must be checked. Oil insulation ability and the values should be measured. The upper part of the tanks should be vacuum-stated; 设备在保管期间，必须经常检查设备的情况，并做好记录。 Regulary checking and record-making for the equipment are essential during storage. 作业程序内容Working proc
