The Importance Of Suitable Lubricants For Sf6 Circuit Breaker Operating Mechanisms

When importing sf6 circuit breaker operating mechanism from abroad, the lubrication of its operating mechanism must be performed according to the type of grease specified in the instruction manual. The operating mechanism contains various mechanical components such as bearings, guide devices, and actuation mechanisms, and its motion performance directly depends on the friction state between these components. If lubrication is inadequate, even if the arc-extinguishing chamber of the sf6 circuit breaker spring mechanism itself is designed properly, its cutting or closing action may still fail due to mechanical obstruction. Applying appropriate lubricants (such as silicone-based or fluorosilicone greases) to these mechanical components can maintain the smooth operation of the operating mechanism.
