220kV single-circuit double-cable terminal tower mounting structure for offshore wind plant
The invention discloses a 220kV single-circuit double-cable terminal tower mounting structure for an offshore wind plant. The 220kV single-circuit double-cable terminal tower mounting structure comprises a cable terminal tower, and the cable terminal tower is provided with a fixing platform, a side-phase wire hanging cross arm, a tower body middle-phase wire hanging point and a ground wire cross arm; the number of the fixing platforms is three, each fixing platform is provided with two cable outdoor terminals, and the two cable outdoor terminals are respectively connected with the same-phase double cables through double copper bars, so that the form conversion between the cables and the overhead conductor is completed. A novel double-copper-bar design structure is adopted, the defects that lead wires of two cable terminal heads are different in length and disordered in arrangement are overcome, meanwhile, heat dissipation of the bare double copper bars is better, the power transmission capacity requirement of current-carrying capacity is met, other electrical performance requirements of economic current density, thermal stability, dynamic stability verification and the like are met, and the cable terminal head is high in practicability. And meanwhile, the requirement of mechanical strength can be met, the cable terminal base can be stably fixed, and the connection of the cable terminal wiring terminal is firm and reliable.
本发明公开了海上风电场220kV单回路双根电缆终端塔安装结构，包括电缆终端塔，电缆终端塔设置固定平台、边相导线挂线横担、塔身中相导线挂点和地线横担；固定平台设置为三个，每个固定平台上设置两个电缆户外终端，两个电缆户外终端分别通过双铜排与同相双根电缆连接，完成电缆与架空导线的形式转化。本发明采用新型双铜排的设计结构，避免两个电缆终端头导线引线长短不一、布置杂乱的缺点，同时裸双铜排的散热更佳，既满足载流量的电力输送容量要求，又满足经济电流密度、热稳定和动稳定校验等其它电气性能要求，同时还可以满足机械强度的要求，能够使电缆终端头底座固定稳定、电缆终端头接线端子连接牢固可靠。
