[0002] A circuit breaker is a mechanical 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 are classified into high-voltage circuit breakers and low-voltage circuit breakers according to their application range; generally, those above 3kV are referred to as high-voltage electrical appliances. A reclosing circuit breaker is a device in a power system whose main function is to automatically reclose the circuit breaker after a transmission line fault occurs, thereby restoring power supply. Reclosing circuit breakers reduce power outage time and improve power supply reliability by detecting line faults and automatically performing reclosing operations.
[0003] Existing reclosing circuit breakers with power supply interference resistance generally have a relatively simple fixing method and require tools for operation, making them cumbersome and inconvenient to install. Furthermore, since the circuit breaker is generally made of plastic, it is easily damaged after repeated disassembly and assembly, which is not conducive to long-term use. Therefore, there is a need for a reclosing circuit breaker with power supply interference resistance. Utility Model Content

[0023] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.
[0024] Please see Figure 1-4This utility model provides a technical solution: a reclosing circuit breaker with anti-power interference function, comprising a reclosing circuit breaker body 1 and an easy-to-operate fixing mechanism. The easy-to-operate fixing mechanism includes a circuit breaker mounting plate 2, a locking block 6, a moving plate 7, a rectangular locking block 9, a sliding rod 10, a connecting plate 11, a limiting plate 12, a telescopic rod 14, and a spring 15. The circuit breaker mounting plate 2 is slidably connected to the surface of the reclosing circuit breaker body 1, the locking block 6 is fixedly connected to the surface of the reclosing circuit breaker body 1, the moving plate 7 is slidably connected to the surface of the reclosing circuit breaker body 1, and the rectangular locking block 9 is slidably connected to the surface of the reclosing circuit breaker body 1. Inside the locking block 6, the rectangular locking block 9 is slidably connected to the circuit breaker mounting plate 2. The sliding rod 10 is slidably connected inside the reclosing circuit breaker body 1. The top of the sliding rod 10 extends out of the reclosing circuit breaker body 1 and is fixedly connected to the moving plate 7. The connecting plate 11 is fixedly connected to the bottom of the sliding rod 10 and is fixedly connected to the rectangular locking block 9. The limiting plate 12 is fixedly connected to the surface of the connecting plate 11 and is slidably connected to the inner wall of the locking block 6. The telescopic rod 14 is fixedly connected to the bottom of the connecting plate 11, and the spring 15 is fixedly connected to the bottom of the connecting plate 11.
[0025] Furthermore, there are four easy-to-operate fixing mechanisms, which are respectively set at the four corners of the reclosing circuit breaker body 1. The surface of the circuit breaker mounting plate 2 is provided with a positioning groove 4 for the sliding of the locking block 6. The locking block 6 is adapted to the positioning groove 4. The surface of the circuit breaker mounting plate 2 is fixedly connected with a limiting protrusion 5. The surface of the reclosing circuit breaker body 1 is provided with a locking groove 8. The limiting protrusion 5 is slidably connected to the locking groove 8. The surface of the circuit breaker mounting plate 2 is provided with multiple positioning holes 3 at equal intervals. Each positioning hole 3 is adapted to the corresponding rectangular locking block 9. The inside of the locking block 6 is provided with a receiving groove 13 for accommodating the components in the easy-to-operate fixing mechanism. The connecting plate 11 is L-shaped.
[0026] Furthermore, when installing the reclosing circuit breaker body 1, the locking block 6 is aligned with the positioning slide groove 4, and the locking groove 8 is aligned with the limiting protrusion 5, so that the reclosing circuit breaker body 1 is slidably installed on the surface of the circuit breaker mounting plate 2. At this time, the two moving plates 7 are touched at the same time, causing the two moving plates 7 to move, which in turn drives the sliding rod 10 and the connecting plate 11 to move. The compression spring 15 causes the telescopic rod 14 to retract, the connecting plate 11 moves and causes the rectangular locking block 9 to retract into the interior of the locking block 6. After the position of the reclosing circuit breaker body 1 is determined, the two moving plates 7 are released so that the corresponding rectangular locking block 9 is reset and locked into the corresponding positioning hole 3 on the circuit breaker mounting plate 2, thereby achieving stable fixation of the reclosing circuit breaker body 1.
[0027] Furthermore, the easy-to-operate fixing mechanism enables the rapid installation and fixing of the reclosing circuit breaker body 1, which is convenient to operate, flexible to use, and saves time. It solves the problem that the existing anti-power interference reclosing circuit breakers generally have a relatively simple fixing method, require tools during operation, making them more troublesome and inconvenient to install, and are prone to damage after repeated disassembly and assembly, which is not conducive to long-term use.
