- 摘要:
- 气体绝缘全封闭组合电气（ GIS ）的户外产品气动机构储气罐热镀锌端盖的内腔出现腐蚀问题，影响产品运行可靠性。经分析确认，腐蚀原因为内壁热镀锌层残留锌渣在清理时造成镀层破损，从而导致防腐能力减弱。通过对图纸的工艺性分析和设计结构的改善，有效缓解了锌渣残留的问题，降低了清理强度，解决了储气罐内壁热镀锌层的腐蚀问题，并验证了方法的实际效果。改善后的储气罐能通过 12 周期中性盐雾试验，确保了基材的防腐效果。
- Abstract:
- ： The inner cavity of the hot-dip galvanized end cover of the air storage tank of the pneumatic mechanism of the outdoor product of gas insulated switchgear （ GIS ） has corrosion problems ， which affects the operation reliability of the product. After analysis ， it is confirmed that the corrosion is caused by the damage of the coating caused by the residual zinc slag of the hot-dip galvanized coating on the inner wall during cleaning ， resulting in the weakening of the anti-corrosion ability. Through the process analysis of the drawing and the improvement of the design structure ， the problem of zinc residue is effectively alleviated ， the cleaning strength is reduced ， the corrosion problem of hot-dip galvanized coating on the inner wall of air storage tank is solved ， and the practical effect of the method is verified. The improved air storage tank can pass the 12 cycles neutral salt spray test ， and the anti-corrosion effect of the substrate is maintained.
