The invention relates to a zinc oxide valve piece fitting method based on a homoenergetic principle and a single-column zinc oxide arrester matching method. According to the homoenergetic principle, the zinc oxide valve piece can be subjected to homoenergetic fitting to ensure that the integration of product of voltage and current of each column of zinc oxide valve piece of the arrester over timetrends to be uniform in the voltage change process; the homoenergetic principle means that when the arrester operates, the absorbed energy is the integration of the product of the voltage and currentover time. The zinc oxide valve piece fitting method based on the homoenergetic principle and the single-column zinc oxide arrester matching method in the invention can solve the problem that the zincoxide valve piece with poor performance can accelerate the failure or even the breakdown of the whole group of arresters due to the large number of the zinc oxide valve pieces, the large difference in the volt-ampere characteristics or the large residual voltage dispersity of the single piece and prevent the direct current system from being forced to stop.
