Description
Technical field
The present invention relates to converter transformer valve sides to connect outlet structure design field, more particularly, to a kind of current conversion station converter transformer valve
Side casing bridges connecting line construction.
Background technology
In ± 800kV ultra-high voltage converter stations, two group of 12 concatenated mode of connection of pulse conversion valve tower of generally use, often
12 pulsation valve group of group is arranged in a valve Room.A, the valve side set of the converter power transformer (referred to as " change of current change ", similarly hereinafter) of B, C three-phase
Pipe is inserted directly into inside the valve Room, and be connected to the change of current valve tower of one-to-one A, B, C three-phase of phase sequence by pipe busbar respectively
Connecting terminal.
For the ultra-high voltage converter station in conventional low earthquake intensity area, since the horizontal acceleration of earthquake is small, change of current valve tower
Corresponding hunting range is smaller under earthquake operating mode, and the wiring radian of the connection flexible circuit conductor of suspension insulator can offset converter valve
Earthquake displacement between the value side bushing that the connecting terminal of tower and the change of current become.But for being in high earthquake intensity, as earthquake is strong
Not less than 8 degree areas of degree, ultra-high voltage converter station, since site earthquake intensity is high, displacement of the converter valve under earthquake operating mode compared with
Greatly.It is calculated for example, being analyzed by actual emulation, for high earthquake intensity area 800kV ultra-high voltage converter stations, high-end 800kV
Earthquake amplitude of fluctuation at the connecting terminal of converter valve is likely to be breached 1.5m.Obviously, soft the leading of conventional suspension insulator connection
The wiring radian of line cannot meet the antidetonation needs of the converter valve in high earthquake intensity area.Simultaneously as 800kV change of current valve towers
This body weight is 4-5t, if using the connection type of conventional suspension insulator connection flexible circuit conductor, due to suspension insulator
