The invention discloses a transmission device for independent type grounding switch divide-shut brakes. The transmission device comprises a base, a push-pull rod arranged above the base and an outputshaft driven by a power device to move horizontally and rotationally, a gear is mounted on the output shaft above the base, a rack is meshed with the gear, a slide chute is arranged in the base, a slider matched with the slide chute is arranged under the rack, a spherical-hinge base is fixedly connected to the tail end of the rack, on end of the push-pull rod is hinged with the rack through the spherical-hinge base while the other end of the same is hinged with one end of a limit rod, one end of the limit rod is fixedly connected with a rotating shaft, two ends of the rotating shaft are mounted on a bearing block through a bearing, the bearing block is fixed on the base, and a transmission rod is fixedly connected on the rotating shaft while the other end of the same is hinged with the lower end of a moving contact.
Description
Technical field [0001] The invention relates to the technical field of a transmission device for the opening and closing of a grounding switch, in particular to a transmission device for the opening and closing of an independent grounding switch. Background technique [0002] Grounding switch is an important part of high-voltage combined electrical equipment, and it is a mechanical switch device used to realize equipment grounding. The installation form of grounding switch in combined electrical appliances is divided into independent type and combined type, and the operating mechanism of grounding switch is divided into manual operation type and electric operation type. Manual operation type is low-speed grounding switch, and electric operation type is fast. Type grounding switch. Once the grounding switch has an abnormal grounding fault, it is very easy to cause a partial power failure of the equipment or the entire station, which will have a greater impact on the safe and reli...
