摘　　要：特高压杆塔试验基地加荷塔是铁塔真型试验的主要承力系统之一,加荷塔的试验能力需要满足1000kV特高压交流同塔双回、±1000kV特高压直流单回与±800kV特高压直流双回等输电线路铁塔真型试验的需求。为此,加荷塔的设计参数选择至关重要。根据收集到的特高压铁塔设计资料,兼顾特高压输电线路远期的发展,确定了特高压杆塔试验基地3基加荷塔的高度、宽度与加荷点数等参数。多基特高压杆塔真型试验的顺利完成,印证了加荷塔设计参数选择的合理性。The loading structure （loading towers） of an UHV transmission tower test base is one of the main loading system for prototype tower test and the loading capacity of the loading towers need to satisfy the testing requirements of the prototype towers of 1 000 kV UHVAC double-circuit,±1 000 kV UHVDC single-circuit as well as ±800 kV UHVDC double-circuit.Selection of design parameters is thus very important for loading structures.According to the collected design information of UHV transmission towers,and with consideration of the future developments of UHV transmission lines,the design parameters,including height,width and number of loading points,were determined for the loading structures of the UHV testing towers ,which have been proved reasonable through prototype test of several UHV towers.
