AI Technical Summary
The closing mechanism of existing frame circuit breakers is prone to loosening under vibration, leading to closing operation failure, prolonging power outage time, and affecting the normal operation of the power system.
The design incorporates a combination of components such as clamping studs, connecting plates, insulating plug frames, anti-loosening washers, lever switches, limit blocks, and abutment protrusions. Springs and chamfered structures enhance connection stability and prevent loosening, while anti-loosening washers prevent the clamping studs from loosening.
Stable connection of the circuit breaker closing mechanism is achieved under vibration environment, ensuring quick and convenient operation, preventing connection loosening, and improving the safety and reliability of electrical connection.
