Selection of Grease for Operating Apparatus of Indoor High Voltage Switchgear
High voltage switch is the most important switching equipment in power system,and the lubrication of its op-erating mechanism is an important factor affecting the operation of the switch.The mechanical structure characteristics,working conditions and types of friction,and the lubrication requirements of the typical parts of the operating mechanism were analyzed,and suitable lubricating greases were proposed.The extreme pressure property and life of the proposed grea-ses were predicted by model and machine learning method,the wear of operating mechanism under the lubrication of the proposed greases was predicted by S-N curve approximation and reliability calculation method,verifying that the proposed greases meet the lubrication and service life requirements of operating mechanism.
