Abstract

The invention discloses a rack-and-pinion type transmission mechanism of an automatic changeover switch device. The transmission mechanism comprises a first gear, a second gear and a rack, wherein the two ends of the rack are provided with dentiform sections, and the middle of the rack is a flat and straight section; the first gear is rotatablely arranged on one end of a base body of the automatic changeover switch, and the second gear is rotatablely arranged on the other end of the base body; and the rack is simultaneously meshed with the fist gear and the second gear, the rack is connected with a driving mechanism which is used for pushing the rack to carry out reciprocating motion, the first gear is linked with a first moving contact of the automatic changeover switch device, and the second gear is linked with a second moving contact of the automatic changeover switch device. The rack-and-pinion type transmission mechanism of the invention has the advantages of simplicity, strong anti-shock / vibration capacity, small impact force and little bounce when the contacts are separated and connected, and great improvement on the operating reliability.

Description

technical field [0001] The invention belongs to a low-voltage switchgear, in particular to an automatic transfer switchgear. Background technique [0002] Automatic transfer switching equipment (ATSE) is mainly used in emergency power supply systems. It is a switching device that automatically switches the load circuit from one power supply to another (standby) power supply to ensure continuous and reliable operation of important loads. Therefore, ATSE is often used in important places where electricity is used, and its product reliability is particularly important. Once the conversion fails, it will cause one of the following two hazards: short circuit between power sources or power failure of important loads (even short power failure), the consequences are serious. This will not only cause economic loss (stopping production, financial paralysis), but also may cause social problems (putting life and safety at risk). Therefore, the industrially developed countries all focu...
