高损耗电力变压器的改造

High-loss Power Transformers Reconstructing

近年来，新设计的低损耗中小型电力变压器S9系列已大批量投入电网运行，取得了显著的节能效果。但由于电网中仍存在大量高损耗变压器，造成大量的电能损耗。节约能源，合理利用资源，成为当今社会走可持续发展道路的必要保证。通过对变压器铁芯降低磁密改造及线圈增加匝数，并对改造前后的产品性能、经济效益对比和变压器改造实例分析，进一步表明对原有高损耗变压器采用新材料和新工艺改造，既能达到节约大量资金，又能达到高效利用能源的目的。

In recent years, small low-loss S9 series of transformers have been used in electricity net and energy wasting is reduced evidently, but many high-loss transformers are still running and wasting a lot of electricity energy. Saving energy and using resource economically are necessary to the societyis keeping continuous development. The paper introduces a technique to reconstruct high-loss transformers by setting down flux density of cores and increasing circles of windings, then loss will be decreased and much money will be saved compared with producing new transformers. An example shows the results exactly.
