宁德变压器的运输和验收

宁德变压器的运输和验收
    1.运输
    1)宁德变压器从制造厂到用户，可因地制宜地选用火车、汽车或船只运输。
    2)宁德变压器一般装满油整体运输，其套管、开关附件、储油柜等均不必拆卸。中型宁德变压器也可以充氮运输，将散热器、储油柜、套管、净油器、开关附件等拆卸后另行装箱，安装时再行组装。充氮气运输是将宁德变压器本体内的油放去(留小部分油)，充氮气，由压力表全程监视(如发现低于要求时应及时补充氮气)。安装时放去氮气并注回宁德变压器油。
    3)运输及安装过程中，起吊宁德变压器时，应使用箱壁上的吊攀，吊攀可以承受总装后并注满油的宁德变压器总重量。箱盖上的吊环仅起吊器身时用，起吊时钢索与垂线之夹角不得大于30°。否则应采用专用横梁起吊宁德变压器。
    4)在装卸和运输过程中，不应有冲击或严重振动情况。利用机械牵引时，牵引的着力点应在宁德变压器重心以下.以防倾倒。运输倾斜角不得大于15°。否侧可在订货时提出，以便做好加固措施.防止内部结构变形.移动速度以减少宁德变压器振动为原则，不宜过急。装卸时应防止车辆弹簧弹力或船只浮力而引起宁德变压器倾倒。
 
    2.验收和储存
    1)收到宁德变压器以后，应立即按铭牌检查规格是否与所需的相符，随之查对产品和附件是否齐全，并检查宁德变压器有无漏油、渗油现象，易损部件如套管、油位计、信号温度计、吸湿器等是否损坏。
    2)宁德变压器如不立即安装和投入运行而需长期存放时，必须装上在运箱中拆下的储油拒、吸湿器。并注油到当时气温的油面线上。将宁德变压器垫高垫平，防止水淹。所有密封处应封好.宁德变压器在保管期间，每三个月检查一次，检查有无渗油，油位是否正常，外表有无锈蚀；并应每六个月检查一次油的绝缘强度。
 
Transport and acceptance of the transformer
 
    1 Transportation
    1) adapter from the manufacturer to the user, can be adapted to local conditions to use the train, car or ship transport.
    2) distribution transformers are generally filled with oil the overall transport, and its casing, switch accessories, storage cabinets, etc. do not have to be removed. Medium-sized transformer can also be nitrogen transport, heat sink, storage cabinets, casing, oil purifier, switch attachments demolition prior to packing, installation, re-assembled. Sufficient nitrogen transport is to put this body of transformer oil (leave a small portion of oil), nitrogen filling, full surveillance by the pressure gauge (as found below the requirements should be promptly added nitrogen). Let go of nitrogen and injected back into the transformer oil.
    3) Transportation and installation process, lifting the transformer tank wall hanging climbing, hanging climbing can withstand the total weight of the assembly after the oil filled transformer. Rings only on the lid when lifting the body of the lifting wire rope and vertical angle of not greater than 30 °. Otherwise it should be a dedicated beam lifting transformer.
    4) during handling and transport, there should be no impact or severe vibration conditions. Use of mechanical traction, pulling the focus should be below the transformer center of gravity to prevent the dumping. Transportation tilt angle not greater than 15 °. No side in order to do in order to reinforce measures to prevent internal structural deformation movement speed in order to reduce transformer vibration principle, should not be too hasty. Loading and unloading should be to prevent the vehicle spring force or vessel buoyancy caused transformer dumping.
 
    (2) acceptance and storage
    1) received transformer should immediately whether the nameplate check the specifications consistent with the desired, followed by checking the products and accessories are complete, and check whether the transformer oil spill, oil leakage phenomenon, vulnerable parts such as casing, oil meter, signal thermometers, moisture and other damage.
    2) transformer, if not immediately install and put into operation and need long-term storage must be packed in the shipping box, remove the reservoir refused breathers. And oiling to the temperature of the oil surface line. Transformer booster cushion to prevent flooding. All seals should be sealed transformers in the custody of the check once every three months to check for oil leakage, oil level is normal appearance with or without corrosion; and every six months, check the oil dielectric strength.
