AI Technical Summary

Technical Problem

Existing pole-mounted circuit breakers present a contradiction between improving insulation reliability and ensuring mechanical drive reliability, and there is also a conflict between the integration of equipment functions and the convenience of on-site maintenance, especially in terms of dynamic seal leakage and maintenance complexity.

Method used

It adopts magnetic coupling non-contact drive technology, which drives the contacts to open and close through the rotation of permanent magnet rotor, eliminating the dynamic sealing point that penetrates the air box, and adopts a modular plug-in design for the integrated control power supply compartment, realizing functional decoupling and rapid maintenance.

Benefits of technology

This greatly improves the long-term reliability of gas insulation, reduces equipment maintenance time, and enhances the stability of mechanical transmission and equipment online rate.

Abstract

The invention discloses an intelligent isolation type quick circuit breaker, and belongs to the technical field of high-voltage switch equipment. The circuit breaker comprises a horizontal sealed gas tank, a driving coil module and a pluggable control power supply integrated cabin. An arc extinguish chamber cavity, a permanent magnetic mechanism cavity and a sensor cavity are arranged in the gas tank, and a moving contact rotating shaft of the vacuum arc extinguish chamber is rigidly and directly connected with an output shaft of the permanent magnetic mechanism through an insulating coupling band. The driving coil module is arranged outside the gas tank in a sleeving mode, the internal permanent magnet rotor is driven to rotate in a magnetic coupling non-contact mode, and therefore a contact is driven to be opened and closed, a dynamic sealing point penetrating through the gas tank is thoroughly eliminated, and the long-term reliability of gas insulation is greatly improved. The control power supply integrated cabin adopts a modular plugging design, integrates protection, communication, hybrid energy taking and driving circuits, and can be quickly replaced when a fault occurs, so that the maintenance time is greatly shortened. The system has the advantages of high reliability, quick action, low maintenance cost and intelligent monitoring, and is suitable for protection and control of the overhead line of the power distribution network.
