AI Technical Summary
Technical Problem
The disconnecting switches of existing pole-mounted circuit breakers are prone to aging in outdoor environments, leading to poor contact and affecting the stability of the power system.
Method used
The conductive plate is held by a conductive clamp, and the conductive column and conductive plate are wrapped with a protective sleeve. Combined with the drive mechanism, contactless opening and closing is achieved. The bending mechanism reduces contact wear, and the heat dissipation effect is improved by the protective sleeve and the non-powered fan.
Benefits of technology
It slows down the aging of conductive components, improves the operational stability of the power system and the service life of the circuit breaker, and makes operation safer and more reliable.
