[0002] A reclosing switch is an electrical device used for self-restoring power supply. Closing a circuit breaker in a short period of time is called reclosing. Since most overhead line faults are actually instantaneous or temporary, reclosing is one of the self-restoring power supply methods commonly used in operation. A circuit breaker refers to a switching device that can close, carry and disconnect currents under normal circuit conditions and can close, carry and disconnect currents under abnormal circuit conditions within a specified time. Circuit breakers are divided into high-voltage circuit breakers and low-voltage circuit breakers according to their scope of use. When loading, it is generally necessary to use the reclosing switch in conjunction with the circuit breaker equipment and connect them through wiring.

[0056] In the embodiment of the utility model, the fixed installation of the gusset plate 103 and the connection between the assembly bolts 102 of the bracket frame 101 and the plate carrier mechanism 6 enhance the overall stability of the bracket mechanism 1 and provide a solid foundation for the loading mechanism.

[0058] In the embodiment of the utility model, by using the support frame 101, the assembly bolts 102 and the gusset plate 103, the support mechanism 1 may provide stronger structural support and increase the stability of the entire system. The assembly support frame 602, the assembly hole group 603 and the rivet 601 of the carrier mechanism 6 may provide a reliable connection method to ensure the stable assembly of the carrier mechanism and reduce the risk of loosening or falling off of parts. An auxiliary sliding end sleeve 1601 is fixed in the auxiliary support sleeve 16, which is connected to the auxiliary side sleeve 5 by sliding, providing additional support, and the end edge of the auxiliary sliding end sleeve 1601 is in the shape of an arc surface, which may help reduce friction and make sliding smoother.

[0060] In the embodiment of the utility model, the threaded shaft 11 can slide smoothly in the telescopic bushing 13 through the design of the auxiliary sliding mechanism 17, which includes the second bearing 1701 and the sliding block 1702. This smooth sliding can ensure the stability and accuracy of the device during adjustment. The construction of the auxiliary sliding mechanism 17 enables the end of the threaded shaft 11 to be connected to the second bearing 1701 and to be rotatably mounted with the sliding block 1702 through it.

[0061] Working principle: When adjusting the bearing area and the mounting hole position of the entire device, the transfer plate mechanism 6 is pulled, which drives the threaded shaft 11 to rotate, and then drives the threaded shaft 11 to spirally rotate and move in the internal threaded tube 15, and then drives the telescopic sleeve 2 to slide on the surface of the telescopic bushing 13, drives the auxiliary side sleeve 5 to slide on the surface of the auxiliary support sleeve 16, and then drives the auxiliary side sleeve 5 to extend or contract the supporting structure fixed on both sides of the auxiliary support sleeve 16, that is, drives the two carrier plate mechanisms 6 to extend or contract, and then can provide loading for the reclosing switch and the circuit breaker respectively. When the side end is fixed to the external mechanism, it can be fixed by the fixed installation mechanism 8 connected to the connecting seat 7 and the rotating adjustment installation plate mechanism 12.
