摘　　要：根据电接触理论，分别对３种不同结构形状触头的电接触性能进行了分析研究，从室内和室外两种环境的试验结果及理论分析得出，Ｈ型触头具有最佳的电接触性能，桥式双断点触头的电接触性能最差。Electrical contact characteristics of three contacts with different configurationswere studied according to the electrical contact theory in this paper,the experiments which werecarried out in outdoor and indoor and theoretical calculations all showed the H-contacts keeps thehighest reliability,on the contrary,the bridge contacts has the worst results.
