Study on Installation Technology of 35 kV GIS Switchgear in Xiaolangdi Power Supply System
In order to optimize the installation effect of 35 kV GIS switchgear in the Xiaolangdi power supply system,im-prove the sealing performance of the switchgear,and ensure its long-term stable operation,a new installation technology is proposed.This installation methodology includes first,the preparation of the necessary tools and instruments for the in-stallation of the switchgear to lay a solid foundation for the installation,second,installing the switchgear body,fixing it on the foundation,connecting the busbars inside the switchgear,third,installing a GIS gas insulation system,and finally,using the upper in and upper out wiring method to install and debug the secondary circuit.The installation test results show that after the application of this technology,the gas leakage rate of 6 groups of GIS switchgear is considerably low-er,and significant results have been achieved in improving the sealing performance of the switchgear.
