意大利平板点焊机电极烧损的分析

Analysis about the electrode melt of Italy plate weld machine

对平板点焊机电极烧损做了分析:电网高压的窜入击穿二极管,导致主变压器某二次侧线圈短路使三相二次侧绕组电流严重失衡,电流瞬时巨增而烧损电极。

This article analyzes the burn-out electrode of plate weld machine,which including the high voltage fled in disorder from the power source strikes these diodes,the current pass in through the second coil of the transformer cause unbalance,the huge current in short time burned the electrode in order to avoid it.
