Abstract—

The article notes that the use of electric contact grease is one of the effective methods for improving the reliability of connections in electrical engineering, which is relevant due to the rapid development of electric transport and increasing requirements for the environmental friendliness of lubricants. Тhe production of grease, which, in addition to tribological efficiency, has electrically conductive properties in a tribosystem, can be achieved by providing a stable dispersed system with a high content of solid lubricants and electrically conductive components. The effect of introducing the electroconductive particles into the grease composition to provide electrically conductive properties was studied. Technological methods for obtaining the electric contact grease have been developed. It has been established that with an increase in the content of electroconductive filler in grease, the wear index and colloidal stability decrease with an increase in the dropping point and shear strength. The optimal content of the electroconductive filler was determined while maintaining the required tribological and physicomechanical characteristics of the electric contact grease. The prospects of using biodegradable oils as the basis for greases are noted.

电接点润滑脂的功能特性

摘要——

文章指出，使用电接触润滑脂是提高电气工程连接可靠性的有效方法之一，这与电力运输的快速发展以及对润滑剂环保性要求的不断提高有关。润滑脂的生产除了摩擦效率外，还具有摩擦系统中的导电性能，可以通过提供具有高含量固体润滑剂和导电成分的稳定分散系统来实现。研究了将导电颗粒引入润滑脂组合物中以提供导​​电性能的效果。已经开发出获得电接触润滑脂的技术方法。已经确定，随着润滑脂中导电填料含量的增加，磨损指数和胶体稳定性随着滴点和剪切强度的增加而降低。在保持电接触润滑脂所需的摩擦学和物理机械特性的同时，确定了导电填料的最佳含量。使用可生物降解油作为润滑脂基础的前景受到关注。
