Description

Technical Field

[0001] This invention relates to the field of circuit breakers, specifically to a switch circuit breaker for an intelligent ring main unit. Background Technology

[0002] A ring main unit is an electrical device consisting of a set of high-voltage switchgear installed in a steel plate metal cabinet or assembled into a modular ring main power supply unit. Its core components are load switches and fuses. It has the advantages of simple structure, small size, low price, improved power supply parameters and performance, and power supply safety. Switches and circuit breakers are usually installed at the power line access point to automatically disconnect the circuit in case of overload, short circuit, or undervoltage faults.

[0003] Currently, Chinese patent application number CN202023124930.8 discloses a circuit breaker, including a circuit breaker body and a switch disposed on the front side of the circuit breaker body. A protective mechanism is sleeved on the outside of the switch. The protective mechanism includes a first cover, a second cover, a connecting block, a telescopic rod, a spring, and a locking block. The protective mechanism includes a first cover disposed on the top of the switch, a second cover disposed at the bottom of the first cover, and a connecting block fixedly connected to the top of the second cover near the circuit breaker body. By setting the first cover and the second cover, the switch of the circuit breaker body can be blocked to prevent accidental opening. The connecting block, telescopic rod, spring, locking block, and locking groove can push the second cover upward, so that the locking block is locked in the locking groove of the first cover under the elastic force of the spring, thus facilitating the blocking of the switch. When it is necessary to open, simply press the locking block to disengage it from the locking groove, which is convenient for operation.

[0004] However, existing circuit breakers typically only lock and secure the energized wiring during use. When pulled by external forces, the wiring can easily become loose, affecting the safety of energization. Furthermore, during the vertical lifting and lowering of the switch to block it, a passageway for the switch needs to be left on the upper and lower sides, resulting in poor protection for the switch.

After the wiring is inserted into the inner side of the through-hole 73, the clamping component 74 clamps and positions the wiring around the wire.

[0036] The locking assembly 74 includes a rotating block 741 rotatably connected to the inside of the side wall of the cover 71, a first rotating rod 742 connected to the middle right side of the rotating block 741, a second rotating rod 743 rotatably connected to the other end of the first rotating rod 742, and a threaded rod 744 connected to the other end of the second rotating rod 743. Under the action of the rotating block 741, the first rotating rod 742 drives the threaded rod 744 to rotate through the second rotating rod 743. A first annular block 745 and a second annular block 746 are respectively connected to the front and rear sides of the outer surface of the threaded rod 744, a cover 747 surrounding the outside of the first annular block 745 and the second annular block 746, and respectively... The clamping components 748 connected to the inner ends of the first annular block 745 and the second annular block 746, under the action of the threaded rod 744, cause the first annular block 745 and the second annular block 746 to move the clamping components 748 inside the cover 747, so as to position the wire when moving inward. The threaded parts on the left and right sides of the threaded rod 744 have the same structure and the thread direction is opposite. There are four clamping components 748, and each of the four clamping components 748 is connected to the first annular block 745 and the second annular block 746 in pairs, so that the four clamping components 748 can rotate synchronously to clamp the wire.

The four columns 7483 move in the first slide groove 7452 and the second slide groove 7462 respectively to make the slider 7482 drive the pressure block 7484 to move laterally.

[0040] Please see Figure 1 , Figure 7 and Figure 8 The present invention provides a switch circuit breaker for an intelligent ring main unit. The protective structure 8 includes a transparent cover 81, support rods 82 fixed to both sides of the rear of the transparent cover 81, and a support assembly 83 connected to the other side of the support rods 82. The support assembly 83 is embedded inside the circuit breaker body 1. The transparent cover 81 is made of ABS resin. The transparent cover 81 flips upward in an arc-shaped trajectory under the support of the support assembly 83.

[0041] The support assembly 83 includes a rotating shaft 831 fixed inside the circuit breaker body 1. A first support block 832 is rotatably connected to one side of the rotating shaft 831. A first connecting rod 833 and a second connecting rod 834 are rotatably connected to the upper and lower parts of the side of the first support block 832 away from the rotating shaft 831, respectively. The other sides of the first connecting rod 833 and the second connecting rod 834 are rotatably connected to a second support block 835. A support shaft 836 is fixedly connected to the middle of the second support block 835, and the other side of the support shaft 836 is rotatably connected to the support rod 82. The support rod 82 rotates on the support shaft 836 and lifts the support shaft 836 upward to avoid jamming when the transparent cover 81 flips upward, ensuring the normal flipping of the transparent cover 81. The first support block 832 and the second support block 835 are arranged in parallel, and the second connecting rod 834 and the second support block 835 are also arranged in parallel. A rectangular structure is formed between the first support block 832, the first connecting rod 833, the second connecting rod 834 and the second support block 835, which facilitates the movement of the support shaft 836 in an arc shape.

[0042] This invention provides an improved switch circuit breaker for an intelligent ring main unit, the working principle of which is as follows;

[0043] First, this design is installed in the intelligent ring network cabinet through the mounting slot 2 for use;

[0044] Second, the power supply inlet and outlet ends in the ring main unit are installed to the upper and lower sides of the circuit breaker body 1 respectively, and bolts are locked into the upper wiring positioning port 3 and the lower wiring positioning port 4 for positioning and fastening.

[0045] Third, after the wiring is installed, the user rotates the rotating block 741. Under the action of the rotating block 741, the first rotating rod 742 drives the threaded rod 744 to rotate through the second rotating rod 743. Under the action of the threaded rod 744, the first annular block 745 and the second annular block 746 rotate inside the cover 747. The two sides of the first annular block 745 drive the two column rods 7483 to move in the two first sliding grooves 7452, so that the slider 7482 drives the pressure block 7584 to move laterally to clamp the wiring on both sides. The two sides of the second annular block 746 drive the two column rods 7483 to move in the second sliding groove 7462, so that the slider 7482 drives the pressure block 7584 to move laterally to clamp the wiring on the other side. The external protective rubber of the wires on all four sides can be pressed and positioned to ensure the stability of the wiring connection.

[0046] Fourth, when the operating switch 5 is not operated, the transparent cover 81 protects the outside, allowing the circuit breaker body 1 to be seen through the transparent cover 81 and preventing accidental contact. When the operating switch 5 needs to be operated, the transparent cover 81 is flipped upwards. The transparent cover 81 rotates on the support shaft 836, and the support shaft 835 moves in an arc shape on the rectangular structure formed by the first support block 832, the first connecting rod 833, the second connecting rod 834, and the second support block 835. This causes the transparent cover 81 to flip upwards in an arc shape, after which the operating switch 5 can be operated.

[0047] This invention provides an improved intelligent ring main unit circuit breaker. The operating switch 5 has a status indicator light at its front end for monitoring the switch's status. A positioning structure 7 for auxiliary fixing of the wiring is installed on the top side of the circuit breaker body 1. Rotating the rotating block 741 causes four pressure blocks 7484 to move laterally, clamping and positioning the outer insulating rubber layer of the wiring, further fixing the wiring and preventing loosening that can easily occur from fixing only the metal parts, thus improving wiring stability. A protective structure 8 is provided on the front side of the operating switch 5 to prevent accidental operation. When the operating switch 5 is not in use, a transparent cover 81 covers and protects the outside of the operating switch 5 to prevent accidental contact. When operation is required, the transparent cover 81 rotates on the support shaft 836, causing the support shaft 835 to move in an arc shape, thus causing the transparent cover 81 to flip upwards in an arc shape. After flipping up, it can be used to... The operation switch 5 is used for operation and has good protection. The first annular block 745 is rotatably connected to the top rear side of the first internal thread block 745, and the first internal thread block 7451 is wrapped around the outer end of the threaded rod 744 and threadedly connected to it. When the threaded rod 744 rotates, the first internal thread block 7451 drives the first annular block 745 to rotate. The first annular block 745 has two parallel first sliding grooves 7452 on its left and right sides, and the inner sides of the two first sliding grooves 7452 are respectively connected to two pressing components 748, so that the pressing components 748 can move within the first sliding grooves 7452. The first support block 832 and the second support block 835 are arranged in parallel, and the second connecting rod 834 and the second support block 835 are also arranged in parallel. The first support block 832, the first connecting rod 833, the second connecting rod 834 and the second support block 835 form a rectangular structure, which facilitates the movement of the support shaft 836 in an arc shape.
