Abstract：For the problem of metal oxide arrester (MOA) failure under the action of multiple return-strokes with long continuous current, based on the field-circuit coupling calculation method, the effects of long continuous current, amplitude of return-strokes, number of return-strokes and the interval time of multiple return-strokes on the temperature rise characteristics of the MOA are studied when the lightning strikes the 500kV DC transmission lines. The temperature rise of MOA under the action of multiple return-strokes with long continuous current is analyzed after considering the thermal accumulation effect and surface flashover. The results show that the long continuous current and the interval time of multiple return-strokes have little effect on the temperature rise of MOA, and the maximum temperature rise of MOA can reach 150.7℃ under the action of 10 return-strokes. After the thermal accumulation effect is considered, the maximum temperature rise increases by about 6.6℃. In the process of multiple return-strokes, when the single section surface flashover fault of the MOA occurs, the continuous current will make the fault arc unable to extinguish, which will cause the MOA temperature to rise rapidly and the thermal collapse is more likely to occur.
