[0002] The integrated primary and secondary pole-mounted circuit breaker equipment is an intelligent power equipment that integrates primary and secondary equipment. It is mainly used in power distribution networks and undertakes functions such as line protection, fault isolation, and power distribution. It integrates the traditionally separately designed primary equipment (such as the circuit breaker body) and secondary equipment (such as the control unit, protection unit, communication unit, etc.) into one device, achieving high integration, intelligence, and efficiency of the equipment.

[0003] The existing primary and secondary fusion pole-mounted circuit breaker equipment has an inner steel tube inside to decompose a large amount of non-conductive gases such as carbon dioxide and nitrogen under the high temperature of the arc, forming a longitudinal high-pressure airflow to blow out the arc. The chemical arc extinguishing method cannot perform good arc extinguishing work in some environments. For example, in high-altitude areas, the air pressure is low, which may lead to insufficient gas pressure and inability to effectively blow the arc. Therefore, it is particularly important to propose a primary and secondary fusion pole-mounted circuit breaker with a mechanized arc extinguishing mechanism to reduce the damage and combustion of equipment caused by the arc.

[0015] The beneficial effects of the present invention are: 1. The present invention adopts an arc extinguishing mechanism design structure so that in a normal power-on state, the elastic force provided by the elastic component is greater than the rebound magnetic force of the movable contact component and the magnetic induction component, so that the top end of the movable contact component and the bottom end of the magnetic induction component are plugged into each other to form a circuit. When a short circuit occurs, the magnetism of the magnetic induction component is enhanced, and the elastic force provided by the elastic component is less than the rebound magnetic force of the movable contact component and the magnetic induction component. The top end of the movable contact component slides under the insulating block, and several insulating blocks are tightly connected to form a fully closed arc extinguishing structure, which cuts off the arc and forms a short circuit. It can be used in high-altitude areas, solving the technical problem that the chemical arc extinguishing method cannot perform good arc extinguishing work in some environments.

[0016] 2. The present invention adopts the structural design of the arc extinguishing assembly. When the insulating block is located in the adapting groove, the movable column is located at the eccentric end of the inclined guide groove. Several insulating blocks are separated from each other to form a movable channel. The movable channel is used as a movable contact assembly and an arc passes through. When the adjusting ring rotates, the movable column moves on the inclined guide groove, so that the insulating block rotates with the rotating rod as the rotation axis, and the arc is rotationally cut from the outside to the inside, so that the gas in the movable channel flows relatively, and the stability of the arc is reduced, thereby reducing the thermal damage of the arc to the insulating block, until the movable column moves to the centripetal end of the inclined guide groove, and several insulating blocks are closely connected to form a fully closed arc extinguishing structure, which cuts off the arc and isolates the arc to prevent the arc from reigniting, thereby extinguishing the arc to form a short circuit.

[0017] 3. The present invention further designs the insulating block so that when the insulating block cuts the arc, the arc is divided into multiple segments, and the energy of each arc segment is significantly reduced, thereby reducing the concentrated heat effect of each arc segment and reducing the thermal damage of the insulating block, thereby protecting the insulating block. Each arc segment with reduced energy is extinguished independently in its own arc extinguishing chamber, and the arc extinguishing process is more efficient and rapid. The arc extinguishing chamber provides more dispersion space for the arc. Several preparatory grooves on the same plane are designed to be connected to form a windmill-shaped arc extinguishing chamber, so that during the formation of the arc extinguishing chamber, the preparatory grooves drive each arc segment to be blown obliquely, further dispersing the arc energy, thereby further reducing the thermal damage of the insulating block and improving the arc extinguishing efficiency.

[0018] 4. The present invention extends the movable distance of the movable contact assembly by providing a straight guide groove B, so that the arc below the insulating block can be further extended, protecting the thinner wall portion of the top of the connecting rod with the plug-in groove, thereby reducing damage to the connecting rod.

[0019] 5. The present invention adopts the structural design of the elastic component, so that the elastic force of the elastic component in the initial state provides a vertical upward force for the connecting ring block, which is used for plugging the auxiliary plug slot and the bottom of the fixed contact to power on in the normal power-on state. When a momentary short circuit occurs due to an accidental touch, the magnetic force generated by the magnetic induction coil becomes larger, causing the movable contact component to slide down, and the connecting ring block drives the rotating joint located on the rotating seat to move downward. The time for the plug slot and the fixed contact to separate and generate an arc is very short, and no damage will be caused. At this time, the rotating joint moves downward for a short distance. When the current returns to normal, the rotating joint located on the rotating seat The rotating joint on it is still diagonally above the rotating joint located in the middle of the rotating cavity, and the elastic force of the elastic component still provides a vertical upward force for the connecting ring block, so that the plug-in slot and the fixed contact can be reinserted, reducing unnecessary circuit breaker and power outage maintenance and reducing economic losses. When the short circuit time is long, the connecting ring block drives the rotating joint on the rotating seat to move downward to the diagonally below the rotating joint located in the middle of the rotating cavity. The elastic force of the elastic component still provides a vertical downward force for the connecting ring block, accelerating the sliding of the movable contact assembly, thereby accelerating the arc extinguishing speed of the arc extinguishing assembly and reducing damage.

[0020] 6. The present invention adopts the structural design of the jump adjustment component, so that in the initial state, the upper inclined surface of the triangular block and the elastic component jointly provide a vertical upward force for the connecting ring block to prevent the plug slot from being separated from the fixed contact due to the change of the conventional current, so that when the magnetic force generated by the magnetic induction coil becomes larger, when the movable contact component slides down, the connecting ring block slides relative to the upper inclined surface of the triangular block, and the spring B is compressed so that the triangular block provides a greater force for the connecting ring block. When the plug slot and the fixed contact are just separated, it is in the jump state, and at this time, the connecting ring block just moves to the corner of the triangular block. Therefore, the rated current passing through the magnetic induction coil during tripping varies based on the magnitude of the vertical upward force provided by the triangular block to the connecting ring block. Therefore, by rotating the adjusting screw block, the threaded rod drives the movable block B to slide along the movable slot B, causing the spring B to expand and contract. The triangular block is adjusted to provide the connecting ring block with the magnitude of the vertical upward force, thereby adjusting the rated current of the plug-in slot and the fixed contact to be disengaged. When the plug-in slot and the fixed contact are disengaged to generate an arc, the connecting ring block moves down to contact the lower inclined surface of the triangular block. At this time, the lower inclined surface of the triangular block provides a vertical downward force to the connecting ring block, which makes the connecting ring block and the entire movable contact assembly move downward faster, thereby increasing the arc elongation speed and reducing damage.

[0029] In the embodiment of the present invention, the movable contact assembly 7 includes a connecting rod 71, which is arranged on the cavity 43. A plug-in groove 72 is provided at the top of the connecting rod 71. The plug-in groove 72 is plugged with the bottom of the fixed contact 53. An insulating tube 73 is fixed on the surface of the connecting rod 71. A connecting ring block 74 is fixed in the middle of the insulating tube 73. A plurality of rotating guide grooves 75 are provided in an annular structure with equal spacing on the surface of the insulating tube 73 relative to the upper position of the connecting ring block 74. A plurality of ball blocks 652 are movably connected to the plurality of rotating guide grooves 75 respectively. The rotating guide groove 75 includes a straight guide groove A751. A partial threaded guide groove 752 is provided at the top of the straight guide groove A751. A straight guide groove B753 is provided at the top of the partial threaded guide groove 752. A slide bar 76 is fixedly provided on the surface of the insulating tube 73 at a position below the connecting ring block 74. The slide bar 76 and the insulating tube 73 constitute a slide rod unit. The slide rod unit is slidably connected to the slide groove 42. The bottom end of the slide rod unit passes through the slide groove 42 and is fixedly provided with an adjustment block 77. An annular groove 78 is opened at the top of the insulating tube 73, and a magnetic ring 79 is fixedly provided on the annular groove 78. The present invention provides a downward sliding force for the movable contact assembly 7 by setting a magnetic ring 79 to repel the magnetic force generated by the magnetic induction coil 52; the entire movable contact assembly 7 slides down, the slide rod unit slides down along the slide groove 42, and the ball block 652 moves on the straight guide groove A751.

[0030] In the embodiment of the present invention, the elastic component 8 includes a swivel seat 81 and two swivel joints 82.

When a momentary short circuit occurs due to an accidental touch, the magnetic force generated by the magnetic induction coil 52 becomes larger, causing the movable contact assembly 7 to slide down, and the connecting ring block 74 drives the swivel joint 82 located on the swivel seat 81 to move downward. The time for the plug slot 72 to separate from the fixed contact 53 to generate an arc is very short, and no damage will be caused. At this time, the swivel joint 82 moves downward a short distance. When the current returns to normal, the swivel joint 82 located on the swivel seat 81 The movable joint 82 is still located diagonally above the rotating joint 82 in the middle of the rotating cavity 44, and the elastic force of the elastic component 8 still provides a vertical upward force for the connecting ring block 74, so that the plug-in slot 72 and the fixed contact 53 are reinserted, reducing unnecessary circuit breaker power outages and maintenance, and reducing economic losses. When the short circuit time is long, the connecting ring block 74 drives the rotating joint 82 on the rotating seat 81 to move downward to the diagonally below the rotating joint 82 in the middle of the rotating cavity 44. The elastic force of the elastic component 8 still provides a vertical downward force for the connecting ring block 74, accelerating the sliding of the movable contact assembly 7, thereby accelerating the arc extinguishing speed of the arc extinguishing assembly 6 and reducing damage.

[0031] In an embodiment of the present invention, the take-off adjustment component 9 includes a movable block A91, a movable block B92 and a threaded rod 93. The movable block A91 is movably arranged on the movable groove A45. The movable block A91 is penetrated and fixed with a triangular block 94. The triangular block 94 is movably cooperated with the connecting ring block 74. The connecting ring block 74 is provided with a vertical groove 95 at one end away from the triangular block 94. The movable block B92 is movably arranged on the movable groove B46. The movable block B92 is provided with a plurality of circular grooves 96 at one end close to the vertical groove 95. Each circular groove 96 is elastically connected to the vertical groove 95 by a spring B97. The spring B97 is truncated cone-shaped. The threaded rod 93 is threadedly connected to the insulating shell 4 relative to the movable groove B46. The end of the threaded rod 93 close to the movable block B92 is inserted into the movable groove B46 and is rotatably connected to the movable block B92. An adjusting screw block 98 is fixed on the threaded rod 93. The present invention adopts the structural design of the jump adjustment component 9, so that in the initial state, the upper inclined surface of the triangular block 94 and the elastic component 8 jointly provide a vertical upward force for the connecting ring block 74 to prevent the plug slot 72 from being separated from the fixed contact 53 due to the change of the conventional current, so that when the magnetic force generated by the magnetic induction coil 52 becomes larger, when the movable contact component 7 slides down, the connecting ring block 74 slides relative to the upper inclined surface of the triangular block 94, and the spring B97 is compressed so that the triangular block 94 provides a greater force for the connecting ring block 74, and the plug slot 72 is just separated from the fixed contact 53 when it is in the jump state, at which time the connecting ring block 74 just moves to the corner of the triangular block 94, Therefore, the rated current passing through the magnetic induction coil 52 during the tripping changes based on the magnitude of the vertical upward force provided by the triangular block 94 to the connecting ring block 74. Therefore, by rotating the adjusting screw block 98, the threaded rod 93 drives the movable block B92 to slide along the movable groove B46 to cause the spring B97 to expand and contract. The triangular block 94 is adjusted to provide the connecting ring block 74 with the magnitude of the vertical upward force, thereby adjusting the rated current of the plug-in slot 72 and the fixed contact 53 to be disengaged. When the plug-in slot 72 is disengaged from the fixed contact 53 to generate an arc, the connecting ring block 74 moves down to contact the lower inclined surface of the triangular block 94. At this time, the lower inclined surface of the triangular block 94 provides a vertical downward force to the connecting ring block 74, so that the downward movement speed of the connecting ring block 74 and the entire movable contact assembly 7 becomes faster, thereby increasing the arc elongation speed and reducing damage.

[0032] Working principle: This embodiment provides a primary and secondary integrated column mounted circuit breaker. When in use, the present invention sets the magnetic ring 79 to repel the magnetic force generated by the magnetic induction coil 52 when it is energized, so that the elastic component 8 and the upper inclined surface of the triangular block 94 jointly provide the connecting ring block 74 with a vertical upward force greater than the repulsive magnetic force. When the current is greater than the set rated current or even short-circuited, the magnetic force generated by the magnetic induction coil 52 becomes larger, the movable contact assembly 7 slides down, and the connecting ring block 74 slides relative to the upper inclined surface of the triangular block 94. When the plug-in slot 72 and the fixed contact 53 are just separated, it is in a jump state. At this time, the connecting ring block 74 just moves to the corner of the triangular block 94. Therefore, the rated current passing through the magnetic induction coil 52 during the tripping changes based on the magnitude of the vertical upward force provided by the triangular block 94 to the connecting ring block 74. Therefore, by rotating the adjusting screw block 98, the threaded rod 93 drives the movable block B92 to slide along the movable groove B46 to cause the spring B97 to expand and contract. The triangular block 94 is adjusted to provide the connecting ring block 74 with the magnitude of the vertical upward force, thereby adjusting the rated current magnitude of the plug-in slot 72 and the fixed contact 53 to be separated. When the plug-in slot 72 and the fixed contact 53 are separated to generate an arc, the connecting ring block 74 moves down to contact with the lower inclined surface of the triangular block 94. At this time, the lower inclined surface of the triangular block 94 provides a vertical downward force for the connecting ring block 74, so that the downward movement speed of the connecting ring block 74 and the entire movable contact assembly 7 becomes faster, thereby increasing the arc elongation speed and reducing damage. When the current returns to normal in a short time, the rotating joint 82 on the rotating seat 81 is still obliquely above the rotating joint 82 located in the middle of the rotating cavity 44, and the elastic force of the elastic component 8 still provides a vertical upward force for the connecting ring block 74, so that the plug-in slot 72 and the fixed contact 53 are re-plugged; When the short circuit time is long, the connecting ring block 74 drives the rotating joint 82 located on the rotating seat 81 to move downward to the obliquely below the rotating joint 82 located in the middle of the rotating cavity 44, and the elastic force of the elastic component 8 still provides a vertical downward force for the connecting ring block 74, accelerating the downward movement of the movable contact assembly 7, thereby speeding up the arc extinguishing speed of the arc extinguishing assembly 6 and reducing damage.
