| 干式变压器与油浸式变压器的优缺点及其区别 Advantages and disadvantages of dry-type transformer and oil-immersed transformer and their differences 1外观 1 appearance 封装形式不同，干式变压器能直接看到铁芯和线圈，而油式变压器只能看到变压器的外壳； Different encapsulation forms, dry transformer can directly see the core and coil, while oil transformer can only see the transformer shell; 2引线形式不同 2. Different lead forms 干式变压器大多使用硅橡胶套管，而油式变压器大部分使用瓷套管； Silicone rubber bushing is mostly used in dry-type transformer, while porcelain bushing is mostly used in oil-type transformer. 3容量及电压不同 3. Different capacities and voltages 干式变压器一般适用于配电用，容量大都在1600KVA以下，电压在10KV以下，也有个别做到35KV电压等级的；而油式变压器却可以从小到大做到全部容量，电压等级也做到了所有电压；我国正在建设的特高压1000KV试验线路，采用的一定是油式变压器。 Dry-type transformers are generally suitable for distribution applications, with capacity mostly below 1600 KVA, voltage below 10 KV, and individual 35 KV voltage levels; while oil-type transformers can achieve all capacities from small to large, and voltage levels can also achieve all voltages; UHV 1000 KV test lines under construction in China must adopt oil-type transformers. 4绝缘和散热不一样 4 Insulation is different from heat dissipation 干式变压器一般用树脂绝缘，靠自然风冷，大容量靠风机冷却，而油式变压器靠绝缘油进行绝缘，靠绝缘油在变压器内部的循环将线圈产生的热带到变压器的散热器（片）上进行散热。 Dry-type transformers are generally insulated by resins, which are cooled by natural air and large capacity by fans. Oil-type transformers are insulated by insulating oil, which circulates in the transformer to heat the heat sink of the transformer. |
