摘　　要：For the purpose of testing and analysing the corona characteristics of UHVDC bundle conductors, UHVDC corona cage would be built in China. Corona cage is one of the indispensable equipments for conductor corona performance researches. Tests of conductor co- rona characteristics in corona cages can overcome the shortages of those with test lines.The dimensions of several corona cages constructed overseas were introduced in this paper. Based on foreign experiences and the requirement of State Grid Corporation of China, the UHVDC corona cage was designed as double-cage, double-layer, three-sections, and catenary shape with the size of 70 m×22 m×13 m. The corona loss measurement system, radio interference measuring system, and the audible noise measuring system are also detailed, including the measurement theory, connection with the cage, the parameters and the designing basis. The UHVDC corona cage has been put into service. It now undergoes a large amount of audible noise and radio frequency interference tests.For the purpose of testing and analysing the corona characteristics of UHVDC bundle conductors, UHVDC corona cage would be built in China.
