| 摘要: |
| 为了探究触点配对方式对汽车继电器电接触性能的影响，选取AgMeO型触头材料进行实验，采用粉末冶金法制备AgSnO2, AgCuO和AgZnO 3种触头材料，并测量其物理性能，采用JF04C电接触触点材料测试系统，按5种不同触点配对方式进行电接触实验，并对实验前后的阴阳极触点进行称量，实验结果表明：触点配对方式对接触电阻，材料转移和损耗影响较大，对燃弧能量的影响较小，通过对触点进行不对称配对可以明显降低接触电阻和材料转移和损耗，明显改善汽车继电器的接触性能. |

| Abstract: |
| In order to investigate the effect of contact pairing mode on the automotive relays electrical contact properties, AgMeO contact materials were selected for experiment.Three kinds of contact materials AgSnO2, AgCuO, and AgZnO were prepared by powder metallurgy method, and their physical properties were measured. The electric contact test was carried out according to five different contact pairing modes using JF04C electric contact materials testing system, then cathode and anode were weighed before and after the experiment. Experimental results show that the contact resistance, material transfer and loss were greatly affected by the contact pairing mode, but the effect on the arc energy was small.Contact resistance, material transfer and loss could be significantly reduced by asymmetric contact pairing, and contact performance of automotive relays could be significantly improved. |
