Problems solved by technology
[0004] Although the above-mentioned reclosing mechanism can perform opening and closing operations during use, when closing and opening, the connecting rod assembly is driven by the gear combination to realize the opening and closing operation, resulting in a slow response speed, which makes it fast when needed. And when the opening and closing operation is performed stably, the opening and closing cannot be performed quickly, effectively and stably, which may easily cause safety accidents

The invention discloses a stable-breaking reclosing switch. According to the technical scheme, the stable-breaking reclosing switch is characterized in that the stable-breaking reclosing switch comprises a switch body located in a switching body, wherein the switch body comprises a driving mechanism, a limiting mechanism and a touch control piece, the driving mechanism comprises a driving source, a pushing component, a transmission piece and a reset driving piece, the transmission piece is connected with the touch control piece and the pushing component, the driving source is used for providing driving force for the pushing component to conduct closing movement, the pushing component drives the touch control piece to conduct closing movement through the transmission piece, the limiting mechanism comprises a limiting buckle, a pressing piece and a limiting elastic piece, the pushing component is in pressing contact with the pressing piece so as to enable the limiting elastic piece to be pressed to deform, the limiting buckle is driven to limit the pushing component, and the reset driving piece provides opening power for driving the touch control piece to move in an opening mode. The stable-breaking reclosing switch has the advantages that quick response can be achieved, opening and closing operation can be stably carried out, quick response can be achieved during opening and closing, and the effect of improving the use safety of the whole reclosing switch is achieved.
Description
technical field [0001] The invention relates to the technical field of electrical safety, in particular to a reclosing switch with stable breaking. Background technique [0002] The leakage reclosing switch in the traditional distribution network, that is, the molded case switch, is opened and closed by a multi-link mechanism in the molded case switch. The structure is complex, the reliability is poor, and the failure rate in use is high. The maintenance and The cost of replacement is high, so there are many disadvantages in actual power distribution applications. [0003] The Chinese patent with the existing notification number CN211150463U discloses a reclosing mechanism of an electrical switch, which includes a motor, a main gear, a connecting rod assembly, an impeller, a manual opening and closing screw and a slave gear, and the motor is fixed to the circuit breaker On the cover, the main gear is mounted on the shaft of the motor through a one-way bearing, and the slave...
