35/10kv干式变压器上限容量多少 限定干式变压器容量要素有哪些

      35KV的干式变压器，按国标GB-10228-2008《干式电力变压器技术参数和要求》，上限容量为20000kVA。一般低电压为400V的无励磁调压电力变压器，按照上述规范，上限容量为2500kVA、315000KVA。超出这一变压器大小得话，原材料成本会高出很多。

       The 35KV dry type transformer has an upper limit capacity of 20000kVA according to the national standard GB-10228-2008 "Technical parameters and requirements for dry type power transformers". Generally, an excitation free voltage regulating power transformer with a low voltage of 400V has an upper limit capacity of 2500kVA and 315000KVA according to the above specifications. Beyond this transformer size, the raw material cost will be much higher.

       1、排热缘故干式变压器的绕阻和铁心排热比油浸变压器艰难，假如容积做大了，变电器容积都大了，成形的绝缘层材料排热更艰难。所以目前一般不建议用大空间干式变压器，其合理性不太好。

       1. Due to heat removal, the winding resistance and iron core heat removal of dry-type transformers are more difficult than oil-immersed transformers. If the volume is increased, the transformer volume is also increased, and the formed insulation layer material is more difficult to heat removal. So currently, it is generally not recommended to use large space dry type transformers, as their rationality is not very good.

　　2、可用场地干式变压器一般都是用以配电设备，例如灯光照明、电子电路等，对容积的要求不高。

       2. Usable dry type transformers are generally used for power distribution equipment, such as lighting, electronic circuits, etc., and have low volume requirements.
