Description

Technical Field

[0001] The utility model relates to the field of electric power fittings, in particular to a pole-mounted circuit breaker with a deep integration of a fast permanent magnet mechanism. Background Technique

[0002] The working principle of a pole-mounted circuit breaker is generally as follows: when the circuit breaker breaks the circuit, an arc will be generated between the moving and static contacts; the pole-mounted circuit breaker usually uses a vacuum interrupter or other arc extinguishing technologies to extinguish the arc; taking the vacuum interrupter as an example, its interior is in a high vacuum state. When an arc is generated due to the separation of the contacts, since there is no air or other gas in the vacuum, the arc is difficult to maintain, and the vacuum has a very high insulation strength; at the same time, under the special structural design of the contacts, an appropriate longitudinal magnetic field will be generated to promote the vacuum arc to remain in a diffused type and make the arc evenly distributed on the surface of the contacts for combustion, maintaining a low arc voltage; at the natural zero-crossing of the current, the remaining ions, electrons, and metal vapor can be recombined or condensed on the surface of the contacts and the shielding cover within the time order of microseconds, and the dielectric insulation strength of the interrupter port is quickly restored, so that the arc is extinguished, achieving the purpose of breaking the circuit.

[0003] When the pole-mounted circuit breaker is installed on a telegraph pole, the pole-mounted circuit breaker is fixed to the telegraph pole through a simple bracket welded by a profiled steel structure. When the pole-mounted circuit breaker is actually installed, it cannot be adjusted in terms of angle and position, and cannot adapt to different installation situations, resulting in poor adaptability; therefore, it is necessary to provide a pole-mounted circuit breaker with a deep integration of a fast permanent magnet mechanism to solve the above technical problems. Content of the Utility Model

At the same time, an adjustment shaft is inserted into the positioning seat, and a fixed seat is fixedly welded to the end of the adjustment shaft. The fixed seat is adapted to the size of the telegraph pole and covers the outer surface of the telegraph pole. At the same time, a hoop is fixedly covered on the side of the telegraph pole away from the fixed seat. A clamping seat covers the bottom of the adjustment shaft, and locking pieces are fixedly installed at both ends of the clamping seat.

[0006] Preferably, both the fixed seat and the hoop are made of metal and are in a semi-circular structure.

At the same time, positioning pieces are fixedly installed on both sides of the fixing seat 5 and the clamp 6, and the fixing seat 5 and the clamp 6 are fixedly connected by fixing bolts; the fixing seat 5 and the clamp 6 are combined together to form an annular fixing cylinder, and the circuit breaker body 1 is installed on the outer side of the electric pole 7 through the annular fixing cylinder.

At this time, the locking pieces 9 on both sides of the holder 8 are fixed to cover the bottom of the base 2 through four groups of second fixing bolts 12.

When the angle and position of the circuit breaker body 1 are adjusted, the first fixing bolts 11 pass through the screw holes opened on the mounting platform 10 and resist the bottom surface of the adjustment shaft 4 to ensure the stability of the adjustment shaft 4 when it is stationary and not easy to loosen.

[0020] The fixing seat 5 and the clamp 6 are both semicircular structures made of metal material, and the fixing seat 5 and the clamp 6 are combined together to form an annular fixing tube, and the circuit breaker body 1 is installed on the outside of the electric pole 7 through the annular fixing tube.

[0025] The working principle of the permanent magnet mechanism in the pole-mounted circuit breaker is as follows: Closing process: When the circuit breaker receives a closing command, the closing coil is energized to generate a magnetic field; this magnetic field interacts with the magnetic field of the permanent magnet to generate a strong electromagnetic suction force, overcoming the reaction force of the spring and other resistances, and pulling the moving iron core downward; the moving iron core drives the contacts of the circuit breaker to close through the transmission mechanism to complete the closing operation; after closing in place, even if the closing coil is de-energized, due to the magnetic force of the permanent magnet, the moving iron core can still be kept in the closing position, making the circuit breaker reliably in the closed state;

[0026] Opening process: When opening is required, the opening coil is energized, and the generated magnetic field direction is opposite to that during closing, so that the moving iron core is subjected to an upward electromagnetic force; this force overcomes the suction force of the permanent magnet and the pulling force of the spring, and pushes the moving iron core upward, and the contacts of the circuit breaker are separated through the transmission mechanism to achieve opening; after opening in place, the opening coil is de-energized, and the moving iron core is kept in the opening position under the action of the spring;

[0027] The working principle of deep integration in the pole-mounted circuit breaker: This type of circuit breaker deeply integrates the permanent magnet mechanism with other parts of the pole-mounted circuit breaker to achieve the protection and control of the circuit; during normal operation, the circuit breaker is in the closed state, allowing current to pass through; when a fault occurs in the circuit, such as overload, short circuit, etc., the circuit breaker can quickly detect the fault signal and trigger the permanent magnet mechanism to perform an opening operation, quickly cutting off the circuit to prevent the fault from expanding and protecting the safety of the line and equipment; at the same time, it may also have intelligent monitoring and communication functions, capable of real-time monitoring of circuit parameters and transmitting data to the control center or other devices for remote monitoring and management.
