Description

Technical Field

[0001] The present invention relates to the technical field of circuit breakers, and in particular to a primary-secondary integrated intelligent pole-mounted circuit breaker capable of rapid wiring. Background Art

[0002] With the development of power grids, digitalization, integration, miniaturization, and intelligence are the main development directions. Primary and secondary equipment are highly integrated to meet the requirements of segmented line loss management, local feeder automation, single-phase ground fault detection, device-level interchangeability, factory-based maintenance, plug-and-play, and automated testing. These requirements address insulation coordination, electromagnetic compatibility, and lifespan matching for complete sets of equipment. Pole-mounted circuit breakers are circuit breakers installed and operated on electric poles. The research and manufacturing technologies for various circuit breakers have made significant progress. Vacuum circuit breakers are no longer limited to medium-voltage power grids but are developing towards high voltage and large capacity. Sulfur hexafluoride circuit breakers have many advantages, including high breaking capacity, high continuous breaking times, frequent operation, low operating noise, and no fire hazard.

[0003] Among them, the patent with publication number CN118553557A discloses a standardized pole-mounted circuit breaker with deep integration of primary and secondary circuits, including an operating box, a sealed pole, a three-stage linkage disconnector and a current transformer. The sealed pole is installed above the operating box, and a wiring terminal is provided on the top of the sealed pole. A transfer terminal is provided on one side of the sealed pole. A metal lever is provided inside the transfer terminal. The current transformer is connected to the sealed pole through the transfer terminal. A ceramic bushing is provided inside the sealed pole, and a transmission rocker is provided below the ceramic bushing. The ceramic bushing includes a sensing air cavity and a working cavity. The three sensing air cavities are on the outside of the working cavity. A buffer spring is provided on the outside of the transmission rocker, and a guide rod is provided inside the transfer terminal.

[0004] When the lock is in use, the inner locking column will move toward the inside of the hollow sliding shaft when the locking contact is contracted, and the displacement shaft on the surface of the lock column will move along the sliding groove inside the hollow sliding shaft. The sliding groove adopts a wave-shaped design. When the displacement shaft moves, it can drive the hollow sliding shaft to rotate counterclockwise through the sliding groove, and the lock disk rotates together, and the engagement operation of the locking block is completed with the help of the movable lock hole. In this way, the locking contact and the locking contact can be locked at the moment of closing the circuit to prevent bouncing between the contacts. However, it is not easy to quickly change the current transmission situation and it is not easy to quickly adjust according to needs because the displacement shaft can drive the hollow sliding shaft to rotate counterclockwise through the sliding groove when it moves. Summary of the Invention

[0005] The present invention provides a primary-secondary integrated intelligent pole-mounted circuit breaker capable of rapid wiring, aiming to solve the problems raised in the above background technology.

[0006] In order to achieve the above objectives, the present invention provides the following technical solution: a primary-secondary integrated intelligent pole-mounted circuit breaker capable of rapid wiring, comprising a first insulating seat on which two groups of control components are provided.

[0007] The regulating component includes a first shell arranged on the top of the first insulating seat, a second shell is arranged on one side of the first shell, and electrode rods are arranged on the tops of the first shell and the second shell.

[0008] The interiors of the first and second shells are both clamped with limiting rings, and each limiting ring is rotatably connected to a swivel, and two conversion parts are provided on the limiting ring and the swivel, and arc extinguishing chambers are embedded in multiple conversion parts, and a first protective plate is plugged into the arc extinguishing chamber, a second protective plate is provided on one side of the first protective plate, a second insulating seat is embedded in the second protective plate, and a contact is provided on one side of the second insulating seat.

[0009] An electromagnetic coil is embedded between the contact and the second insulating seat, a center column is provided between the second protective plate and the first protective plate, current sensors are installed on both sides of the center column by bolts, a first contact pin is installed on the top of the first shell by bolts, a second contact pin is provided on the top of the second shell, and the electrode rod is hinged to the second contact pin, the first contact pin is in contact with the end of the electrode rod, and the first contact pin and the second contact pin are embedded with quick-connect connectors for wiring.

[0010] It can be seen that in the above technical solution, the rotation of the conversion part drives the arc extinguishing chamber, the first protective plate, the second protective plate and the contact to deflect, so that the contacts on the two adjacent conversion parts can contact each other, so that the current transmitted by the wire is transmitted to the conversion parts in contact with each other through the arc extinguishing chamber, the center column, the electromagnetic coil and the contact, and the current sensor detects the current transmission situation. The electromagnetic coil is used to generate a strong magnetic force under short-circuit current, which is convenient for dealing with instantaneous large currents. It can push the contacts to disengage and easily trip. At the same time, when the conversion part deflects, it can also drive the deflection block and the thermistor to adjust their position along the guide rod and the slide groove on the nylon side plate, so that the two thermistors can sense each other when they are close to each other, which makes it easy for the thermistor to heat up and bend due to overload current, triggering tripping.

[0011] Optionally, in a possible embodiment, a nylon side plate is provided at one end of each of the multiple conversion members, and each of the nylon side plates is respectively mounted on the inner wall of the limit ring and the rotating ring by bolts, a sliding groove is provided on each of the multiple nylon side plates, and a scale mark is fixedly provided on the outer side of the nylon side plate, two thermistors are slidably connected in the sliding groove, the two thermistors are stacked, and each of the thermistors is slidably connected to a guide rod, one end of the thermistor is rotatably connected to a deflection block, the deflection block is fixed to the end of the conversion member, and electromagnetic shielding blocks are provided on the top and bottom of the deflection block, a gear ring is fixedly provided on the outer side of the rotating ring, and a first micro motor is provided on the outer side of the gear ring, and the first micro motor is mounted by bolts. On the limiting ring, a driving gear is provided at the output end of the first micro motor, and the driving gear is engaged with the gear ring. A driving motor is installed on one side of the first insulating seat by bolts, and a first insulating linkage rod is provided at the output end of the driving motor. A second insulating linkage rod is hinged on the first insulating linkage rod, and one end of the second insulating linkage rod extends to the middle of the electrode rod, and the second insulating linkage rod is rotatably connected to the electrode rod by an axle pin. One end of each of the multiple conversion parts is provided with a second micro motor for driving the conversion part to rotate, and each of the conversion parts is respectively installed on the limiting ring and the inner wall of the rotating ring by bolts. The electromagnetic coil passes through the second insulating seat and the second protective plate and is embedded in the center column. Wires connected to industrial equipment are provided on multiple arc extinguishing chambers.

[0012] It can be seen that in the above technical solution, when opening and closing the switch, the driving motor drives the first insulating linkage rod to rotate, and then the second insulating linkage rod is deflected, and the second insulating linkage rod drives the electrode rod to deflect along the axis point of the connection between the second contact pin and the electrode rod, so that the electrode rod can contact the first contact pin at the top of the first shell, thereby realizing the function of rapid opening and closing of the current on the first shell and the second shell, and the first micro motor drives the active gear to rotate, and then the active gear drives the gear ring to drive the rotating ring to rotate on the limiting ring, and then the various structures on the rotating ring can make circular motion along the axis of the limiting ring, so that the conversion parts on each limiting ring and the rotating ring and the various structures on the arc extinguishing chamber can be staggered, so that the wires and contacts on each arc extinguishing chamber can convert current, thereby improving the convenience and efficiency of the device in converting current.

[0013] The present invention has the following advantages:

[0014] 1. The present invention uses a second insulating linkage rod to drive the electrode rod to deflect along the axis of the connection between the first contact pin on the top of the second shell and the electrode rod, so that the electrode rod can contact the first contact pin on the top of the first shell, thereby realizing the function of rapid opening and closing of current on the first shell and the second shell;

[0015] 2. When the present invention realizes the internal wiring conversion circuit of the first shell and the second shell, the second micro motor drives the conversion member to deflect. When the conversion member rotates, it drives the arc extinguishing chamber, the first protective plate, the second protective plate and the contact to deflect, thereby enabling the contacts on the two adjacent conversion members to contact each other, so that the current carried by the wire is transmitted through the arc extinguishing chamber, the center column, the electromagnetic coil and the contact to the contacting conversion members. In addition, the current sensor detects the current transmission status. The electromagnetic coil is used to generate a strong magnetic force under short-circuit current, which is convenient for dealing with instantaneous large currents and can push the contacts to disengage, making it easy to trip.

[0016] 3. When the conversion member of the present invention deflects, it can also drive the deflection block and the thermistor to adjust their positions along the guide rod and the slide groove on the nylon side plate, so that when the two thermistors are close to each other, they can sense each other and easily cause the thermistor to heat up and bend due to overload current, triggering a trip.

[0017] 4. In the present invention, the first micro-motor drives the driving gear to rotate, which in turn drives the gear ring to drive the rotating ring to rotate on the limiting ring. This enables the various structures on the rotating ring to perform circular motion along the axis of the limiting ring. This allows the conversion members on the limiting ring and the rotating ring, as well as the various structures on the arc extinguishing chamber, to be staggered, so that the wires and contacts on each arc extinguishing chamber can convert current, thereby improving the convenience and efficiency of the device in converting current.

[0018] To sum up, through the corresponding coordinated use of various structures, the electrode rod can contact the first contact pin at the top of the first shell, realizing the function of rapid opening and closing of current on the first shell and the second shell, the electromagnetic coil and the contact transfer current to the conversion parts in contact with each other, and the current sensor detects the current transmission situation, the electromagnetic coil is used to generate strong magnetic force under short-circuit current, which is convenient for dealing with instantaneous large current, and can push the contacts to disengage and easily trip. When the two thermistors are close to each other, they sense each other, which makes it easy for the thermistors to heat up and bend due to overload current, triggering tripping, and realizing the function of double-layer triggering tripping, and the various structures on the rotating ring can make circular motion along the axis of the limit ring, so that the limit rings and the conversion parts on the rotating ring and the various structures on the arc extinguishing chamber can be staggered, so that the wires and contacts on each arc extinguishing chamber can convert current, thereby improving the convenience and efficiency of the device in converting current.
