Abstract

The design method for connection fitting in valve hall of converter station of UHVDC based on temperature rise is very important for making the rise of temperature of connection fitting in valve hall to be in reasonable bound. Considering that the rising of temperature of connection fitting in valve hall of converter station is very high

the reason is analyzed through experiment and theory. The main reason is that current distributes asymmetrically. The design method of connection fitting in valve hall of UHVDC based on temperature rise is developed

the simulation of current distribution and temperature rise is proceed through FEM

the import size of connection fitting is decided through optimization

the rise of temperature distributes symmetrically. The connection fitting that are designed by the method are tested in term of correlative standards. Compared with traditional connection fitting in valve hall

the rise of temperature of connection fitting that are designed by the method is distributed symmetrically

the value of rise of temperature falls greatly. The developed method is very important for the design of connection fitting in value hall of UHVDC and provides an important reference to the design of other equipment in converter station and on lines.
