Discussion on Shortening the Same Stop Time of Double Busbars in the Installation of 220 kV HGIS Equipment
A method is proposed to shorten the simultaneous shutdown time of double busbars in the installation of 220 kV HGIS equipment,which decomposes the equipment installation into non power outage work and power outage work.By first placing the equipment body in place to the foundation during the power outage period,and then splicing the casing,tapping the busbar,overlapping the busbar and equipment down lead during the power outage period,and completing the body handover test,the power outage time of the busbar,especially the double busbar,can be effectively reduced,which has a positive effect on maintaining the stability of the power system and reducing the economic losses caused by the power outage.
