三相非晶变压器

非晶合金铁芯具有高饱和磁感强度、低损耗（相当于硅钢片的1/3 ～ 1/5），低矫顽力、低激磁电流、良好的温度稳定性等特点，用非晶合金铁芯制造的变压器，其空载损耗只有现行S9产品的1/4 ～ 1/5，空载电流较S9系列下降20%，节能十分显著，特别适用于负载率低的用户，如农村地区和发展中地区。伊戈尔电气股份有限公司生产的SH15型非晶合金产品、铁芯采用单框或三相五柱卷铁芯，铁芯夹紧件用薄板成型框架结构，低压线圈为箔绕式，使其损耗低、抗短路能力强、结构先进合理的总体性能基本达到世界先进水平。 SH15 Series Amorphous Metal Core Distribution Transformer is the best energy-saving distribution transformer in the world at present. It saves energy remarkably that its no-load loss is only 1/4 ～ 1/5 of the present products. It especially applies to the users of low load rate, such as the rural area and the developing region. In order to decrease SH15 series transformers’ losses, to enhance its ability to withstand short circuit, its core is made into single ring core or three-phase five-column core, its core clamp is made as frame structure with laminal sheet metal, its LV winding is foil wound. With the application of these advanced technologies, its macro-property reaches the world top level.
