himself design it under actual demand). 在箱式变基 础的一侧或四周埋设好接地极，变压器接地与防雷接地可以公用一个接地系统。 引至箱式变基础平台的接地引线应不少于两根，并确保接地电阻小于等于 4 欧姆。 Securely bury grounding polar at one side or around packaged substation foundation, transformer grounding and lightningresistant grounding shall share in one grounding system. Grounding fedin line into package substation foundation platform should not be less than two, and assure it is not over 4 ohms grounding resistor. 箱式变应采用专用工具底部起吊，如附图所示，注意吊装标记。 Packaged substation should be hoisted from base and hoisted by special tool, see relative illustration. And note hoisting mark. 箱式变底座与基础之间的缝隙用水泥沙浆抹封，以免雨水进入电缆室。 Use cement slurry to plaster and seal the clearance between packaged substation base and foundation, so that rainwater flows into cable room. 电缆进入电缆室后，电缆与穿管之间的缝隙须密封防水。 After cable enters cable room, this must seal with clearance between cable and infed pipe for better waterproof performance. 5．箱式变电站的操作与维修 Operation and maintenance for packaged substation 箱式变在安装维修后，在投入运行前应检查下列项目： After packaged substation is installed and repaired。 following items should be inspected before formal operation: 9 a、 成套装置内是否清洁； If it is clean and tidy inside packaged device。 b、 操作机构是否灵活； If manipulation device is flexible。 c、 主要电器通断是否灵活可靠； If major electric appliance switches on or off in flexible and reliable form。 d、 仪表与互感器的匹配是否正确，接线及极性是否正确； If instrumentation correctly matches with mutual inductance meter and if wiring and polarity are correct e、 电器辅助接点的通断回路是否可靠、准确； If switchon/off loop at auxiliary joint point for electric appliance is reliable and accurate。 f、 所有电器安装螺母是否紧固； If fixation nut for all electric appliances is tight。 g、 所有母线是否连接良好； If all buses is better connected。 h、 电器整定值是否符合要求，熔断器选择是否正确； If electric appliance mutation value meets relevant requirements, and if fuse is correctly selected。 i、 表计及继电器动作是否准确无误； If meter pointer and relay activation is accurate without any error。 j、 主回路及辅助回路的电气接点是否符合原理图要求； If electric joint between major loop and auxiliary one meets requirement for wiring schematic drawing。 k、 变压器的温控装置是否已调到规定的使用温度； If thermostatic controller for transformer has been adjusted to specified operation temperature。 l、 检查电容器外壳的接地是否良好，放电系统是否可靠； If grounding for capacitor shell is better and if electric discharge system is reliable。 m、 箱式变投运前应对高低压配电设备、变压器计量装置等进行必要的试验，试验合格后，才允许投运。 10 Before transfer for packaged substation, this must first make necessary test for hi/lowvoltage power distribution facility and transformer metering device, it is put into formal transfer only after qualified. 将变压器室门及所有开关设备可以开启的门均关好，所有开关应处 于分闸位置。 Completely switch off transformer room door and those can be opened for all switch devices, all switches should stay at switchoff position. 按操作程序合闸 11KV 进线电源，观察高压室指示仪表，若正常，变压器方可投入运行。 Under operation procedure, switch on 11KV infed power supply, observe meter set at hivoltage room。 if normal, this only can run transformer. 闭合低压室总开关，观察电压指示仪表，若正常，再分别合分路开关，箱式变投入正常运行。 Switch on main lowvoltage switch, observe voltage indicating meter。 if normal, respectively switch on branch switch, then this puts packaged substation into normal operation. Power Transformer 适用范围 Scope of application 本说明书运用于容量为 6300KVA 及以下，电压为 35KVA 以下的油浸式电力变压器。 凡本系列变压器经正常运输后，不需作吊芯检查，即可装配有关拆卸的零部件，做验收试验项目，合格后，便可投入运行。 The instructions are suitable for oilimmersed power transformer with the capacity of 6300KVA and below and the voltage of below 35KVA. This series of transformers needn39。 t to perform suspended core treatments after normal transporation. After assembling the relavant teardown parts and ponents and being qualified in acceptance test, they can be put into use. 变压器的运输 Transportation of the transformer 1． 变压器至安装地点的运输方法：主要为公路或铁路运输。 此类变压器一律装满油运输，应附带的零件，配套件，出厂技术文件等，另装成箱与变压器一起发运。 Transportation approach of the transformer to the installation site: mainly by highway or railway transporation. This kind of transformer should be transported in fulloil container without exception. The incidental parts, auxiliary equipments and technical d。
