[0002] A circuit breaker is a switching device capable of closing, carrying, and interrupting current under normal circuit conditions and closing, carrying, and interrupting current under abnormal circuit conditions within a specified time. Circuit breakers can protect power lines and motors, automatically disconnecting the circuit when they experience severe overload, short circuit, or undervoltage faults. Their function is equivalent to a combination of a fuse switch and over / under-temperature relays.
[0003] Circuit breakers have a wide range of applications, including power systems, industrial sectors, and building construction. Ring main units (RMS) in power systems utilize circuit breakers; high-current RMS units, in particular, have numerous internal circuits and require multiple circuit breakers for safety. While circuit breakers of the same type are often installed side-by-side, they are independent of each other and must be installed individually, requiring position adjustments. This leads to lengthy installation times and low work efficiency. Utility Model Content

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0021] like Figure 1-6As shown, this utility model discloses a ring network high current circuit breaker, including a circuit breaker 1. The circuit breaker 1 is provided with an installation assembly. The installation assembly includes an installation block A2 and an installation block B3 fixedly disposed on the rear side of the circuit breaker 1, a snap fastener 4 and a sleeve 5 fixedly disposed on the left and right sides of the circuit breaker 1 respectively, an installation plate A6 located on the rear side of the circuit breaker 1, an installation block C7 fixedly disposed on the front side of the installation plate A6, and an installation plate B8 located on the rear side of the installation plate A6 and having the same structure as the installation plate A6. The installation block A2 is located above the installation block B3. The installation block C7 is located between the installation block A2 and the installation block B3 and is detachably connected to both. The installation plate A6 and the installation plate B8 are detachably connected. In use, since mounting plate A6 and mounting plate B8 have the same structure, mounting block C7 and locking block C12 on mounting plate B8 are inserted into the locking groove 14 on mounting plate A6, so that mounting plate A6 is located in front of mounting plate B8. The elastic ball 15 on mounting plate A6 will be inserted into the ball groove 16 on mounting plate B8, thus fixing mounting plate A6 and mounting plate B8. Pulling down the sliding bracket 9 moves locking block B11 downward, placing mounting block C7 between mounting block A2 and mounting block B3, so that locking block C12 is located in the locking block A10. Loosen the sliding bracket 9 on the front side of the locking block B11 so that it is springed back to its original position by the spring 30, so that the locking block C12 abuts against the locking blocks A10 and B11, thus fixing the circuit breaker 1 to the mounting plate A6; after passing the screw through the mounting holes A19 on the mounting plate A6 and mounting plate B8, fix it to the ring main unit cabinet to complete the installation of the circuit breaker 1; when multiple circuit breakers 1 need to be installed, insert the snap 4 on the circuit breaker 1 into the socket 5 on the other circuit breaker 1 in advance, so that the two circuit breakers 1 are assembled together, and insert the plug 24 into the two circuit breakers 1. Insert the plug 24 into the socket B27, so that the magnetic post 25 is magnetically connected to the iron plate on the left side wall of the sliding frame 9. Pulling the plug 24 downward will drive the sliding frame 9 and the locking block B11 on the two circuit breakers 1 to move downward, and then install the two circuit breakers 1 on the mounting plate A6 at the same time. When more circuit breakers 1 need to be installed, remove the mounting plate B8 from the rear side of the mounting plate A6 and place it on the right side of the mounting plate A6. Insert the positioning plate 22 on the mounting plate A6 into the positioning groove 23 on the mounting plate B8. At this time, the protrusions 20 on the mounting plate A6 and the mounting plate B8 are aligned. Tighten the screws. The nail passes through the mounting holes B21 on mounting plates A6 and B8 and is fixed to mounting plates A6 and B8 with nuts, thus fixing mounting plates A6 and B8 in place. Another set of assembled circuit breakers 1 is then installed on mounting plate B8, completing the installation of multiple circuit breakers 1. In summary, this utility model has the beneficial effect of facilitating the installation of multiple circuit breakers 1, solving the problem that circuit breakers 1 are independent of each other, requiring individual installation and position adjustment, resulting in long installation times and low work efficiency.
[0022] Preferably, the mounting assembly further includes a sliding bracket 9, a locking block A10 fixedly disposed below the mounting block A2, a locking block B11 fixedly disposed above the sliding bracket 9, and locking blocks C12 fixedly disposed on the upper and lower sides of the mounting block C7. A sliding groove 13 is provided on the rear side wall of the mounting block B3. The sliding bracket 9 is inserted into the sliding groove 13 and slidably connected to the mounting block B3. The locking block C12 is located in front of the locking blocks A10 and B11 and abuts against them. Because the locking block C12 is located in front of the locking blocks A10 and B11 and abuts against them, the locking block C12 will lock in front of the locking blocks A10 and B11, thus fixing the circuit breaker 1 to the front of the mounting plate A6.
[0023] Preferably, the rear sidewall of the mounting plate A6 has a slot 14 that matches the mounting block C7 and the locking block C12. An elastic ball 15 is fixedly disposed on the front sidewall of the slot 14, and a ball groove 16 is disposed on the front sidewall of the mounting plate A6. When the mounting plate A6 is located in front of the mounting plate B8, the elastic ball 15 on the mounting plate A6 will insert into the ball groove 16 on the mounting plate B8, thereby preventing the mounting plate A6 from sliding freely.
[0024] Preferably, the mounting assembly further includes a spring 30, a pressure plate A17 fixedly disposed on the rear side of the sliding frame 9, and a pressure plate B18 fixedly disposed on the front side wall of the sliding groove 13. The pressure plate A17 is located above the pressure plate B18, and the upper and lower ends of the spring 30 are fixedly connected to the pressure plate A17 and the pressure plate B18, respectively. Since the upper and lower ends of the spring 30 are fixedly connected to the pressure plate A17 and the pressure plate B18, the spring 30 will be compressed and deformed when the sliding frame 9 is pulled down. When the sliding frame 9 is released, the spring 30 will spring the sliding frame 9 back to its original position, thus achieving the function of automatically resetting the sliding frame 9.
[0025] Preferably, the mounting plate A6 has a through mounting hole A19 extending from front to back, a protrusion 20 is fixedly disposed on the top of the mounting plate A6, and a through mounting hole B21 is formed on the left and right sides of the protrusion 20. A positioning plate 22 is fixedly disposed on the right side of the mounting plate A6, and a positioning groove 23 matching the positioning plate 22 is formed on the left side wall of the mounting plate A6. Since the positioning groove 23 matching the positioning plate 22 is formed on the left side wall of the mounting plate A6, when the positioning plate 22 on the mounting plate A6 is inserted into the positioning groove 23 on the mounting plate B8, the protrusions 20 on the mounting plate A6 and the mounting hole B21 on the mounting plate B8 will align, which facilitates the fixing of the mounting plate A6 and the mounting plate B8 and prevents the mounting plate A6 from rotating after fixing.
[0026] Preferably, the mounting assembly further includes a plug 24, a magnetic post 25 fixedly disposed on the left side of the plug 24, a plug hole A26 opened on the left side wall of the mounting plate A6, a plug hole B27 extending through the left and right sides of the sliding frame 9, and iron plates fixedly disposed on the left side walls of both the mounting block A2 and the sliding frame 9. Since the sliding frame 9 has plug holes B27 extending through the left and right sides, inserting the plug 24 into the plug holes B27 on the two circuit breakers 1 facilitates the pulling of the two circuit breakers 1. Since the mounting block A2 and the left side wall of the sliding frame 9 are both fixedly disposed on iron plates, when the plug 24 is inserted into the plug hole A26 or the plug hole B27, the magnetic post 25 will magnetically connect with the iron plate on the left side wall of the mounting block A2 or the sliding frame 9, preventing the plug 24 from falling out.
[0027] Preferably, anti-detachment strips 28 are fixedly provided on the left and right sides of the sliding frame 9, and anti-detachment grooves 29 are provided on the left and right side walls of the sliding groove 13. The anti-detachment strips 28 are inserted into the anti-detachment grooves 29 and slidably connected with the mounting block B3. Since the anti-detachment strips 28 are inserted into the anti-detachment grooves 29 and slidably connected with the mounting block B3, they play a role in preventing the sliding frame 9 from falling off.
[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
