The Importance of LubricationIn high-voltage circuit breakers, lubrication plays a crucial role. Not only does lubrication affect the service life of the circuit breaker, but it also directly impacts its safety and reliability. Poor lubrication can lead to slow operation of the circuit breaker and even failure to function properly at critical moments, resulting in serious power system failures.Why is lubrication essential in the high-voltage circuit breaker operating mechanism?Lubrication in the

When connecting an AC microgrid to a DC distribution system, several potential issues may arise. Here's a detailed analysis of these problems:1. Power Quality Issues Voltage Fluctuations and Stability: Voltage fluctuations in AC microgrids can affect the stability of DC distribution systems. DC systems have higher requirements for voltage stability, and any fluctuations can lead to a decline in system performance or equipment damage. Harmonic Pollution: Nonlinear loads in AC microgrids can gener

Differences Between Ground Rods and Surge ProtectorsGround rods (Ground Rod) and surge protectors (Surge Protector) are two different electrical devices that serve distinct roles in electrical systems. Here are the main differences between them:1. Ground Rod (Ground Rod)DefinitionGround Rod is a metal rod, typically made of copper or copper-coated steel, buried in the ground to provide a low-impedance path for electrical currents to flow into the earth.Function Provide Grounding Path: The primar
