1. 安装前应认真阅读本说明书和产品铭牌, 了解产品重量、安装方法等内容，准备好相应的起吊设备和工具。

Read this manual carefully before installation to understand product weight and installation method, etc. Prepare right hanging equipment and tools.

2. 本产品作为户内式使用，应安装在场地清洁、通风良好和具有合适的大气条件的户内场所。如果变压器安装在地下室或其他空间受限制的地方时，应有足够的通风，一般变压器每1kW 损耗，应有4米3/分钟的空气通风量。

For indoor using, make sure clean place, good ventilation and right environment. For underground and restricted space using, make sure enough ventilation (1kw loss needs 4cubit meter/min ventilation).

3. 本产品安装时，一般应离开墙壁和其他障碍物300mm ，相邻变压器之间应有

300mm 以上的距离。但对于配电箱和其他安装空间有限的场合以上距离可适当调整。

This product should be installed 300mm away from wall, barrier and other transformer. If this product is installed in distribution box or other space limited area, the distance can be adjusted properly.

4. 一般情况下，变压器可直接放置在使用场地，安装检查完毕后即可投入运行。对于有防震和其他特殊要求的情况，安装变压器的地基应埋置螺栓，安装时卸下变压器的小车轮，通过螺栓螺母把变压器固定。如果变压器安装位置不是在地面，而是在楼层上，应采取措施（如底部垫橡胶板）以减振。

Normally, the transformer can be put in the site and start running after installation check. For shockproof and other special requirements, put bolts in the base ground of the transformer, remove the wheel and fix the transformer with the bolts and nuts. For upper floor using instead of the ground, take appropriate action such as rubber plate to reduce

vibration.

5. 对变压器进行微量的位置调整，可利用安装在变压器下部的滚轮或利用杠杆原理，使力的作用点作用在变压器下部的夹件上。注意：变压器下部的滚轮不是万向轮，而是只能使变压器前后或左右方向运动。

For minor position adjustment, use wheel under the transformer or push the clamp under the transformer (the lever principle). Note: The wheel under the transformer is not universal wheel. It can only moves forward/backward or leftward/rightward.

注意：不可将力的作用点作用于变压器的风机、引线、线圈和铁心上。

Note: Do not push on the fan, leads, winding and iron core.

七、运行前的检验和试验 7. Inspection and Commissioning before Running

1. 检查所有紧固件、连接件、标准件是否松动，并重新紧固一次。Make sure no loose on all fasteners, connection parts and standard parts. And tighten them again.

2. 检查运输时拆卸的零部件是否已安装妥当，并检查变压器内部是否有异物存在。 Check if all removed parts for shipment are installed and no foreign material in the transformer.

3. 检查风机、温控设备以及其它辅助器件能否正常运行。（温控器/风机配置示意图见附图3）

Check fan, temperature controller and other supporting equipment are running properly. (See Fig.3 for the temperature controller and fan configuration sketch)

温控器可按下表设定调节：Adjust the temperature controller according to the table below:

冷却风机的配备（如有）：Cooling Fan Configuration (if any):

变压器配置的风机，有单相风机和三相风机。具体接线请参见温控器/风机端子接线示意图（温控器端子接线示意图见附图4），端子排在温控器的背面。

Single-phase or 3-phase Fan is provided. For wiring, please refer to temperature controller and Fan terminal wiring sketch (Fig.4 temperature controller wiring sketch). The terminals are located on the back of the temperature controller.

附图3 温控器/风机配置示意图

Fig.3 Temperature Controller and Fan Configuration Sketch

附图4温控器/风机接线端子排示意图

Fig.4 Temperature Controller and Fan Terminal Sketch

4. 检查变压器的外壳和铁心是否已作可靠永久性接地。Check transformer case and core are grounded permanently.

5. 绕组直流电阻的测试。Test DC resistance for winding.

6. 绝缘电阻的测试。一般情况下，绝缘电阻可满足如下值：

Insulation resistance test. Normally the insulation resistance should meet the following requirement:

高压—低压及地high voltage –low voltage/ground≥300M Ω

低压—地 low voltage-ground ≥50M Ω

在比较干燥的环境条件下，以上绝缘电阻值是很容易达到的。但是如果是在空气湿度较大的环境里，变压器的绝缘电阻值会有所下降。一般地，若用额定电压为2500V 的摇表测量，其绝缘电阻值不小于2M Ω（一分钟25℃时的读数），就能满足使用要求。但是，如变压器遭受异常潮湿发生凝露现象，则不论其绝缘电阻如何，在其进行耐压试验或投入运行前，必须进行干燥处理。

In dry condition, the insulation requirement can be met easily. In humid condition, the insulation resistance goes down. Normally, if the resistance value measured by megameter with the rated voltage of 2500V is less than 2 MΩ(25℃, 1min reading), we say it meets the requirement. However, if condensation happens because the transformer gets extremely wet, drying must be done before running.

7. 对于有载调压变压器，应根据有载调压分接开关使用说明书作投入运行前的必要检查和试验。

For on-load tap-changing transformer, necessary inspection and commissioning before running should be done according to the instruction manual of the on-load tap changer.

八、使用8. Use

1. 调整电压 Voltage Adjustment:

在投入运行前，要根据当地电网电压的状况，将连接片联接在相应（在产品上有相应的标志）的档位上。当电网电压高于额定电压时，将连接片联接在1档或2档。反之联接在4档、5档处（档位联接示意图附图5）。电网电压等于额定电压时，联接在3档处。以额定电压比为10/0.4kV,分接范围为±2×2.5%，功率因数0.8, 输出额定

电流时, 当分接向上或向下调一档时, 低压电压将降低或增加9.5V 。即分接向上调可使输出电压降低，分接向下调可使输出电压升高。调整分接位置后，应将分接的连接片充分紧固，避免因接触电阻过大，引起局部过热造成设备损害；同时应注意紧固时不可用力过大，以免造成分接螺母的螺纹损坏。请注意，调压时绝对是在无励磁（即断电）的条件下进行。

附图5 档位联接示意图

Before starting up, connect the connecting sheet to the right channel (there are label on the product) according to the local power network status. If the voltage is higher than the rated voltage, connect to channel 1 or 2. If it is lower, connect to channel 4 or 5 (see Fig 5, channel connecting sketch). If local voltage is equal to rated voltage, connect to channel 3. When the rated voltage ratio is 10/0.4kv, tapping range is ±2×2.5%, power factor is 0.8, and at the rated output current, if connect to 1-level upper or 1-level lower channel, the low voltage will reduce or increase by 9.5V., i.e., tapping increase results in decrease of the output voltage and tapping decrease results in increase of the output voltage. After adjusting, fasten the connecting sheet. Fig 5, Channel Connecting Sketch

To avoid connecting resistance too big to destroy the equipment by local overheating, and to prevent overexerted fastening so as not to destroy the tapping screw. Note, voltage adjustment must be done after power off.

2. 并联运行：若两台（或多台）变压器需要并联运行，只有当变压器的联接组别、高低压额定电压比相同，阻抗电压相差不大于10%时，变压器才可以并联运行。

Parallel Running: If parallel running of 2 or more transformers is necessary, make sure that the vector group and the rated voltage ratio of high and low voltage are same, and the difference of impedance voltage is less than 10%.

3. 请注意产品的接地必须可靠，用户设置的接地网电阻应≤4Ω，在全部安装完成后，请仔细全面地进行检查，不要有金属异物遗留在产品中。

Make sure reliable grounding and the grounding resistance should ≤4Ω. Carefully check after installation to make sure no metal remains in the product.

4. 噪音 Noise：

若变压器在运行中噪音过大，您可参照以下步骤检验，以降低噪音。

⑴低压输出电压是否偏高，可调整分接，降低电压，也可降低噪音。

⑵变压器带防护外壳，可按一下外壳面板，若噪音下降，则紧固面板螺丝即可。 ⑶可用木头顶一下母线槽，若噪音下降，则紧固母线槽螺丝即可。

⑷停电处理，检查外壳上下网板有无异物（螺丝或其他东西）或网板变形是

否较大（安装队安装时有可能踩变形引起振动发出噪音）。紧固变压器主体上下夹件、垫块、母线和其他紧固件的螺丝。检查风机是否松动，是否有异物掉进风机。

⑸检测电源及负载性质，若线路中存在谐波污染或大的整流设备和谐波设备

都会引起谐波振动发出噪音，建议您使用有源滤波器和隔离变压器。

If the noise is too big, check the transformer according to the following steps.

(1) If the low output voltage is too high, tapping can be made to lower the

voltage and to reduce the noise.

(2) Press the case of the transformer to see if noise goes down, if so, fasten the

screw.

(3)

(4) Push the busbar trunking with wood, if noise goes down, fasten the screw. After disconnecting power, check if there is foreign material or big

deformation on the case plates (this may be caused when installation).

Fasten the screws of the clamp, cushion block, busbar and other fasteners.

Check if fan is loose or foreign material inside.

(5) Check power source and load status, if there is harmonic wave pollution or

big rectifying equipment or harmonic wave equipment, we suggest that

you use active filter or isolating transformer.

九、维护 9. Maintenance

尊敬的用户，为使您更安全、可靠、长期地使用，我公司生产的干式变压器产品是需要维护的（而不是完全免维护），维护的内容如下：

For safe, reliabe and long-term use of the product, maintenance is necessary for our transformer. Below are the maintenance items:

1.变压器特别是箔绕式绕组类型产品若停止运行超过72小时（若湿度 ≥95％时允许时间还要缩短）在投运前要做绝缘试验，用2500V 摇表测量，一次对二次及地≥300M Ω，二次对地 ≥50M Ω；铁芯对地≥5M Ω（注意测量前拆除接地片）。若达不到以上要求，请对变压器产品做干燥处理，一般启动风机吹一段时间即可。

If the transformer, especially for the foil-wound transformer, stops running for over 72 hrs( if humidity ≥95％ , the time is shorter), do insulation test before use. Use the 2500V megameter to measure, primary voltage vs. secondary voltage/ground ≥300M Ω, secondary voltage vs. ground ≥50M Ω, iron corn vs. ground ≥5M Ω (remove earthing strip before test). If this can’t be met, dry the transformer by running the fan for a period.

2. 在断电的情况下，定期清理产品表面污秽，表面污秽物大量堆积，会构成电流通路，造成表面过热损坏产品。在一般污秽状态下，可半年清理一次，严重污秽状态下，应缩短清理时间，同时在清理污秽物时，紧固各个部位的螺栓，特别是导电连接部位。

After power disconnection, clean the surface of the product. If too dirty, it will form the current path and cause surface overheat and product broken. For normal status, do the cleaning half a year. For severe dirty status, reduce the cleaning duration, and fasten the screws of each part, especially for the power connection part.

十、注意事项 Notice

1. 本产品按照调压方式可分为有载调压和无励磁调压。用户在订货时需详细注明。

According to voltage adjustment, there are on-load adjustment mold and no excitation adjustment mold. Please mention it when place order.

2. 温控器及风机的具体使用方法可参照随机附带的使用说明书。温控器及风机的电源应通过开关屏获得，而不要直接连在变压器上。

Please refer to the user manual for temperature controller and fan. These two should be powered by switch panel rather than connecting to transformer directly.

3. 变压器安装完毕投入运行之前，对于无外壳的产品，一般应在变压器的周围安装隔离栅栏，以避免人或物意外事故发生。

For transformer without the case, barrier should be installed before using to prevent human and animal.

4. 工作人员进入变压器室一定要穿绝缘鞋，注意与带电部分的安全距离。变压器投入运行以后，禁止触摸变压器主体，以防事故发生。

Operator should wear safety insulation shoes to get in the transformer room, watch out safety distance to powered part. After transformer running, no touch on it.

5. 避雷保护，我们建议您选用相应电压的氧化锌避雷器，避雷器安装要可靠，且距离产品的距离尽可能的小。避雷器的安装和检验请按其相关标准进行。

Lightning protection: use zinc oxide arresters with corresponding voltages, reliable installation, and the distance to product should be as short as possible. Follow relevant standards for the installation and inspection.
