Description

Technical Field

[0001] The present invention relates to the technical field of circuit breakers, and more specifically, to a combined circuit breaker for the Internet of Things. Background Art

[0002] In the manufacturing of power electronic components, combined circuit breakers for the Internet of Things have important uses, mainly in the early warning mechanism. The combined circuit breaker has built-in sensors that can continuously monitor electrical parameters. Once an abnormality is detected, such as overload, short circuit or leakage, it will immediately send an early warning to the user or management system, allowing timely measures to reduce the risk of electrical accidents and realize the combined circuit breaking processing of circuit breakers and the Internet of Things.

[0003] In the existing public documents, the patent with patent publication number CN115799007A discloses a combined IoT AC / DC universal small circuit breaker and its assembly method. This technology is provided with a control board in the electric operation module, and the current signal acquisition board and the voltage signal acquisition board on the circuit breaker body adjacent to the electric operation module are connected to the control board through connecting pins. The split combination design solves the problem of interchangeability between AC and DC products, can flexibly realize single-pole or multi-pole products, improve the reusability of products, and facilitate the maintenance of series products in engineering use. However, this technology still has the following defects.

[0004] In the manufacturing of power electronic components, when the Internet of Things combination circuit breaker is used wirelessly, when the circuit abnormality triggers the double-terminal separation operation, the traditional mechanical structure adopts a single-side terminal fixed mode to asymmetrically separate the static end and the moving end, resulting in non-uniform dissipation characteristics of the arc discharge. Specifically, during the separation process of the moving end, the arc energy is concentrated at a single point on the fixed end and continuously released, forming a local high-temperature aggregation phenomenon. The lack of an effective arc root migration and dispersion path design causes the arc stagnation time to be prolonged. This unilateral arc erosion effect causes the contact material to deteriorate rapidly, and the fixed end ablation depth is large, which greatly shortens the service life of the Internet of Things combination circuit breaker.

The insulating sleeve column rotates clockwise on the outer wall of the support shaft. The contact terminal drives the dispersion terminal to rotate clockwise. The dispersion terminal is vertically separated from the dispersion deflection terminal.

[0013] 2. The present invention adopts a synchronous dispersion and deflection component, enabling the Internet of Things controller to start the micro cylinder. At the same time, the pushing frame moves, the outer gear drives the inner gear to engage and rotate, and the arc isolation block rotates. This enables the dispersion terminal and the dispersion deflection terminal to complete three-dimensional multi-directional separation. At the same time, the arc isolation block accurately embeds into the separation gap to form an insulating barrier, with better arc energy dispersion effect and faster arc dissipation speed, avoiding damage to the dispersion deflection terminal, and greatly extending the service life of the Internet of Things combined circuit breaker.

[0014] 3. The present invention adopts the articulated groove strip to guide and move along the outer wall of the guide rod, and the articulated groove strip drives the moving sliding shaft to rotate, enabling the articulated groove strip to move horizontally stably. At the same time, the fixed block supports the embedded shaft ring, and the outer gear on the embedded shaft ring can stably perform the rotation operation, converting the horizontal movement function of the articulated groove strip into the horizontal multi-angle azimuth deflection and vertical separation drive of the dispersion deflection terminal, with better dispersion synchronization.

[0031] In this technical solution, as Figure 4-9As shown in the figure, an internal gear 18 is rotatably connected below the insulating arc block 14; a terminal 19 is rotatably connected below the internal gear 18.

A limiting ring 22 is fixedly connected to the outer wall of the moving slide shaft 21. The lower surface of the limiting ring 22 is slidably connected to a hinged groove strip 23. The hinged groove strip 23 is slidably connected to the moving slide shaft 21 and is also slidably connected to the external gear 20; on one side of the inner wall of the hinged groove strip 23, a linkage support column 24 is fixedly installed. Inside the hinged groove strip 23 and at a position on one side of the moving slide shaft 21, a guiding rod 32 is installed. Both hinged groove strips 23 are slidably connected to the guiding rod 32, and the guiding rod 32 is fixedly connected to the circuit breaker housing 1. A linkage sleeve shaft 25 is rotatably connected to the outer wall of the linkage support column 24. At a position away from the linkage support column 24 on the inner wall of the linkage sleeve shaft 25, a synchronous pull shaft 26 is rotatably connected. At one end of the synchronous pull shaft 26, a push frame 27 is installed. Both synchronous pull shafts 26 are fixedly connected to the push frame 27, and both hinged groove rings 3 are fixedly connected to the push frame 27. A micro electric cylinder 28 is fixedly installed on the lower surface of the push frame 27.

[0033] The micro electric cylinder 28 is electrically connected to the Internet of Things controller 17 and is fixedly connected to the circuit breaker housing 1. The hinged groove strip 23 is slidably connected to the internal gear 18, and both the inner wall of the hinged groove strip 23 and the outer wall of the moving slide shaft 21 are smooth surfaces. The vertical cross-sectional shapes of both the linkage support column 24 and the synchronous pull shaft 26 are circular, and the center point of the synchronous pull shaft 26 is higher than the center point of the linkage support column 24. The bottom end of the external gear 20 is rotatably connected to an embedded shaft ring 29, and a fixing block 30 is fixedly installed on the lower surface of the embedded shaft ring 29. The fixing block 30 is fixedly connected to the terminal 19. A connection wire harness 31 is fixedly installed at the bottom end of the linkage terminal post 13, and the connection wire harness 31 is fixedly connected to the terminal 19.

[0034] The usage method of the combined circuit breaker for the Internet of Things in the present invention is as follows:

[0035] Step 1: During installation, insert bolts into the installation holes 10 to fixedly install the circuit breaker housing 1 in the distribution cabinet body. Connect the power supply wire harness through the power supply terminal 2, and connect the output wire harness to the terminal 19. Rotate the bolt 16 on the circuit breaker housing 1 to lock the power supply wire harness, and the terminal 19 also fixes the output wire harness in the same way to complete the installation operation.

[0036] Step 2: During power supply, power is supplied to the circuit breaker housing 1 through the power supply harness. The circuit breaker housing 1 supplies power to the power transmission harness 15, the power transmission harness 15 supplies power to the contact terminal 9, the contact terminal 9 supplies power to the dispersion terminal 11, the dispersion terminal 11 supplies power to the dispersion deflection terminal 12, the dispersion deflection terminal 12 supplies power to the linkage terminal post 13, and the linkage terminal post 13 supplies power to the terminal block 19 through the connection harness 31. The terminal block 19 performs a power supply operation on the output harness.

[0037] Step 3: During linkage, when power supply is abnormal and needs to be disconnected, the micro cylinder 28 is started through the Internet of Things controller 17. The micro cylinder 28 pushes the push frame 27 upward. The push frame 27 drives the two synchronous pull shafts 26 upward. The two synchronous pull shafts 26 drive the top of the linkage sleeve shaft 25 upward. The linkage sleeve shaft 25 drives the linkage strut 24 to move to the right, and the other linkage strut 24 moves to the left. The linkage strut 24 drives the articulated groove bar 23 to move to the right. The articulated groove bar 23 guides and moves along the outer wall of the guide rod 32, and the articulated groove bar 23 drives the moving slide shaft 21 to rotate. The moving slide shaft 21 drives the limit ring 22 to rotate. At the same time, both the moving slide shaft 21 and the limit ring 22 slide on the articulated groove bar 23. In this way, the moving slide shaft 21 drives the external gear 20 to rotate. The fixed block 30 is supported by the terminal block 19, the embedded shaft ring 29 is supported by the fixed block 30, and the external gear 20 on the embedded shaft ring 29 can stably perform a rotation operation. The external gear 20 drives a plurality of internal gears 18 to rotate. The internal gears 18 drive the linkage terminal post 13 to rotate on the terminal block 19.

[0038] The linkage terminal post 13 drives the dispersion deflection terminal 12 to rotate. The dispersion deflection terminal 12 deflects and separates from the dispersion terminal 11. At the same time, the linkage terminal post 13 drives the arc isolation block 14 to rotate. The arc isolation block 14 quickly deflects and isolates in the deflection separation gap between the dispersion deflection terminal 12 and the dispersion terminal 11, thereby insulating and blocking between the dispersion deflection terminal 12 and the dispersion terminal 11, and quickly performing lateral dispersion deflection so that the arc between the dispersion terminal 11 and the dispersion deflection terminal 12 can be quickly dispersed and eliminated, avoiding the formation of a high-temperature aggregation phenomenon on the terminal block 19.

[0039] Step 4: During synchronous decentralized deflection, when the pushing frame 27 moves upward, the two articulated groove rings 3 move upward synchronously. In this way, the articulated groove rings 3 drive multiple linkage columns 4 to move upward, and the linkage columns 4 drive the top end of the synchronous sleeve column 5 to move upward. The bottom end of the synchronous sleeve column 5 drives the pulling shaft 8 to rotate, and the pulling shaft 8 drives the insulating sleeve column 6 to rotate clockwise. The insulating sleeve column 6 rotates clockwise on the outer wall of the support shaft 7, and the insulating sleeve column 6 drives the contact terminal 9 to rotate clockwise. The contact terminal 9 drives the decentralized terminal 11 to rotate clockwise, and the decentralized terminal 11 is vertically separated from the decentralized deflection terminal 12. In this way, during the vertical decentralized separation of the decentralized deflection terminal 12 and the decentralized terminal 11, the decentralized terminal 11 and the decentralized deflection terminal 12 can also be deflected and horizontally separated synchronously. The decentralized terminal 11 and the decentralized deflection terminal 12 can disperse the arc energy and quickly dissipate the arc to avoid deep ablation of the wiring terminal 19. The Internet of Things controller 17 is combined with multiple decentralized deflection terminals 12 for decentralized deflection disconnection, greatly extending the service life of the Internet of Things combined circuit breaker.
