低温镀铁是近年来迅速发展起来的一项旧件修复新工艺,它展现出广阔的前景,在很多方面优于喷镀:堆焊和镀铬等旧件修复工艺。对电源的要求,低温镀铁与其它电镀方法相比有共性,也有其特殊性。低温镀铁在起镀时要进行一段正负半波比值不同(即以不同的不对称比)的可调交流镀,然后不断开正半波电流而转入直流镀。这中间有一个不断电的可调的交直流转换过程。下面就把三相平衡电源线路作一介绍。
Low temperature iron plating is a new process of repairing old parts developed rapidly in recent years. It shows a broad prospect and is superior to thermal spraying in many aspects: repairing old parts such as welding and chrome plating. The requirements of the power supply, low temperature iron plating compared with other plating methods have commonalities, but also its particularity. Low-temperature iron plating in the plating should be carried out for a positive and negative half-wave ratio of different (ie, different asymmetry ratio) adjustable exchange plating, and then continue to open the positive half-wave current into DC plating. There is an uninterruptible AC-DC converter in the middle. The following three-phase balanced power lines for an introduction.
