Abstract

High transitional resistance at the joint between conductors may cause power losses and contribute to increased fire hazard on power facilities. This especially concerns aluminum conductors, because the interaction between aluminum and atmospheric oxygen gives rise to stubborn dielectric surface oxide film that considerably increases the transitional resistance. Use of oxidation inhibitors that can substantially reduce the contact resistance is one way to deal with this issue. Here, oxidation inhibitors produced in different countries are compared. The effectiveness of inhibitors is also studied at lower and elevated temperatures. Due to their relatively high effectiveness, the inhibitors can be recommended as a means to reduce the transitional resistance.

评估氧化抑制剂对铝导体之间电连接的有效性

摘要

导体之间接头处的高过渡电阻可能会导致电力损失并增加电力设施的火灾危险。这尤其涉及铝导体，因为铝和大气中的氧之间的相互作用会产生顽固的介电表面氧化膜，从而大大增加了过渡电阻。使用可以显着降低接触电阻的氧化抑制剂是解决这个问题的一种方法。这里比较了不同国家生产的氧化抑制剂。还在较低和较高温度下研究了抑制剂的有效性。由于其相对较高的有效性，可以推荐抑制剂作为降低过渡电阻的手段。
