Analysis of Failure Causes of Grounding Flat Steel for 110kV Transmission Tower
نویسندگان
چکیده
Abstract The corrosion causes of the grounded flat steel a 110kV transmission tower were experimentally analyzed by means macro testing, microstructure inspection, chemical composition analysis, product morphology and energy spectrum, galvanized layer thickness test, soil physical property analysis other test methods. results show that improper selection anti-corrosion process service environment alkaline high salt are main reasons for its fracture. It is proposed power grid equipment should not use grounding cold galvanizing process, inspection in Irrigation areas along Yellow River be strengthened.

Lightning Performance and its Prevention for Quadruple-circuit Transmission Line with 220kV/110kV Voltage in a Tower
According to the physical process of discharge development of insulator that is struck by lightning, the lightning flashover model for quadruple-circuit transmission line with dual voltage 220kV/110kV in same tower is established basing on EMTP. The actual evaluation index of lightning protection performance is adopted with the consideration of influence of system voltage. The characteristics o...
متن کاملCauses of Catastrophic Failure of High Mn Steel Utilized as Crusher Overlaying Shields (TECHNICAL NOTE)
The secondary cone crusher's shields at Sarcheshmeh Copper Complex of Iran are made of Hadfield steel with a nominal composition of Fe-1.3 % C-12 % Mn. They have a cut-off in the shape of a cone with an upper end diameter of 80cm and an approximate lower end diameter of 200 cm whose main problem is an unexpected early failure under normal working condition. In this paper, the results of metallo...
