Description

Technical Field

[0001] The utility model relates to the field of electric power equipment, in particular to an integrated capacitor power-taking type primary and secondary fusion column-mounted circuit breaker. Background Art

[0002] The integrated capacitor-powered, primary-secondary integrated pole-mounted circuit breaker obtains electrical energy through capacitor-powered technology. It controls the primary circuit by opening and closing it, and monitors and protects the line's operating status through the measurement and control functions of the secondary circuit, thereby ensuring the safe and stable operation of the power system. Its capacitor-powered device utilizes the characteristics of capacitors, connecting capacitors between the phase line and ground, or between phase lines, to continuously charge and discharge the capacitors in the electric field to obtain energy.
