The invention relates to an opening and closing device used for operating a handle of a circuit breaker, in particular to an opening and closing device which can integrate manual operation and electric operation. A technology adopted by the invention is that the manual-operation and electric-operation integrated opening and closing device used for the circuit breaker is characterized by comprising a motor arranged on an upper cover of the circuit breaker, a conversion knob, a double-sawtooth batten and a handle bracket, wherein a threaded rod is arranged on an output shaft of the motor; and an opening is formed in one side of the double-sawtooth batten, a thread matched with a thread in the threaded rod is formed in the relative inner side surface of the opening, and the threaded rod and the thread in the inner side surface of the opening are in screw thread fit. With the adoption of the scheme, the problems of the prior art are solved, and one novel manual-operation and electric-operation integrated opening and closing device for the circuit breaker is provided, is convenient to use, mount and dismount and compact in structure, has complete functions, and can achieve switching of manual and electric opening and closing simultaneously.
Description
technical field [0001] The invention relates to a device for operating a circuit breaker handle to open or close. In particular, it refers to a manual and electric integrated opening and closing device. Background technique [0002] At present, circuit breakers on the market adopt manual and electric integrated reclosing mechanisms, and there are mainly two structures. One is a link mechanism; the other is a gear and rack coordination mechanism. [0003] The link mechanism drives the linkage rod through the rotation of the motor shaft, the linkage rod pulls the transmission rod, and the other end of the transmission rod is fixed on the product handle, thereby driving the handle to move forward and backward. The advantage of this mechanism is that the structure is relatively simple. The disadvantage is that manual closing and opening cannot be realized. When the intelligent circuit breaker encounters a power failure or maintenance, it must be manually closed and opened....
