（12）整个装臵区（包括变电所室外）接地装臵构成一个接地网，防雷、防静电、保护接地共用此接地网，接地电阻不大于4Ω。

the earthing device at the whole area of the equipments (including the outside of the transformer station) composes an earth mat, which is a common mat for the lightning arrester, antistatic and protection earth with a earth resistance not more than 4Ω。

（13）施工完毕的接地网因其他专业施工造成断裂的，应及时予以修复。

if the finished earth mat is broken by the construction work of other specialty, rehabilitation should be performed in time.
（14）接地地下部分施工完毕应及时、真实地作好隐蔽工程记录，由甲方（丙方）检查并会签后方可回填土。

if the construction work for the earth underground completes, record of concealed work should be taken in truth and in time. The back filling can be done after inspected and signed by the party A (party C).
（二）变压器安装
Installation of the transformer
1、变压器就位前应调整好基础轨道的水平度，并在其一侧焊上适当垫块使变压器顶盖沿气体继电器方向有1～1.5％的升高坡度。

变压器不带气体继电器时应水平安装。

the levelness of the foundation channel should be adjusted before emplacing the transformer. And proper shim block should be welded at one side of it to form an uprising grade of 1~1.5% for the head cover of the transformer along the gas relay. The transformer without gas relay should be installed horizontally.
2、变压器的滚轮应拆除不用，变压器的基座应用制动装臵加以固定。

The wheel of the transformer should be removed, the foundation of the transformer should be fixed with braking device.
3、变压器是否进行器身检查，除了制造厂规定可不进行的、应根据到货情况和制造厂商量决定。

如果进行器身检查，应编制施工技术措施，由具有相应资质的单位进行。

whether the transformer’s body should be inspected (excepting the unnecessary inspection specified by the manufacturer) is determined with the manufacturer according to the delivery status. If inspecting the body, the construction technical measurement should be prepared and the inspection should be performed by the unit with responding qualification.
4、储油柜安装前应清洗干净，胶囊或隔膜应完整无破损，胶囊应缓慢充气胀开，检查应无漏气现象。

the oil storage tank should be cleaned before installation. The rubber bladder or diaphragm should be complete without any damage. The rubber bladder can expand slowly with gas charging and has no gas leakage.
5、气体继电器安装前应经检验整定，其顶盖标志箭头指向储油柜。

气体继电器的安装须配合储油柜安装一起进行。

the gas relay should be calibrated before installation, the arrow marked on the head cover of it directs to the oil storage tank. The installation of the gas relay will be performed together with the oil storage tank.
6、散热器安装前须检查制造厂的原密封包装是否完好，若有破损应用合格变压器油冲洗以去除杂质。

散热器就位时应注意上下的朝向不可颠倒，吊装时不许直接以钢丝绳绑在散热片上。

散热器到货时若每片制造厂有编号，则安装时须对号入座，若偏差较大安装不上时应暂停，由制造厂来人处理。

before the installation it is required to check whether the original sealing package from the manufacturer of the radiator is in good condition. If there are damages, it should be flushed with transformer oil to remove the foreign substance. When emplacing the radiator, it should be considered that the direction of the top and the bottom should not reverse. When lifting the radiator, it is not permitted to bind the steel wire directly on the radiating pins. If each radiating pin has a number marked by the manufacturer when it delivered, then the pins should be installed according to the numbers. If the deviation is too large and the pins can not be installed, the installation should be stopped temporarily and the personnel sent from the manufacturer will solve the problems.
7、净油器安装前应检查内部装有变压器总油重量2％的干燥硅胶，硅胶滤网应装于净油器的出口侧（下方）。

before the installation it is required to check whether there are drying silica gel inside the oil purifier with amount of 2% of the total weight of transformer oil, the filter cloth of the silica gel should be fixed at the outlet (lower part) of oil purifier.
8、冷却风扇安装应牢固，试转应无振动，风扇叶轮的正确旋转方向是风向上吹。

the cooling fan should be installed tightly, the test run should have no vibration, the correct direction of rotation of the impeller is a direction blowing the wind upward. 9、吸湿器里的硅胶应干燥，油封存油位应在油面线上，油杯拧紧后应松开3mm 左右。

the silica gel inside the dehydrating breather should be dry, the oil storage level of oil seal should be above the oil level, the oil cup should be loosen about 3 mm after it is tightened.
10、防爆装臵若采用压力释放阀，则不可任意拆下，以免造成密封性能变坏。

但在变压器受电前应拆除压力释放阀顶杆上的压板。

if the explosion protection device adapts pressure release valve, then it cannot be。
