Abstract

The invention discloses an operating mechanism and a control and protection switch electrical device with the operating mechanism. The operating mechanism comprises a warning mechanism and a tripping mechanism, wherein the warning mechanism is arranged on a mounting plate. The warning mechanism comprises a side cam and a side stopping device, the side stopping device is provided with a stopping table clamped with and separated from the side cam; the tripping mechanism comprises a middle cam and a middle stopping device, and the middle stopping device is provided with a tripping part clamped with or separated from the middle cam. The operating mechanism further comprises a transmission part, and the transmission part comprises a warning push rod for receiving overload or overcurrent signals, a push plate for receiving short circuit signals and a short circuit push rod. According to the operating mechanism, an alarm is given and a main circuit is opened when short circuit happens; only the alarm is given and the main circuit is not opened in case of overload and overcurrent, the operating mechanism is simple in structure, the side stopping device and the middle stopping device perform motions independently and do not influence each other, the operating mechanism is stable and reliable in motion, and misoperation is effectively avoided.

Description

technical field [0001] The invention relates to the field of control and protection switching devices in low-voltage electrical appliances, in particular to an operating mechanism and a control and protection switching device with the operating mechanism. Background technique [0002] "Control and Protective Switching Device" (or Control Protective Device) is a new product in low-voltage electrical appliances, and its product category code is "CPS", which is the abbreviation of "Control and Protective Switching Device" in English. CPS can realize integrated, internally coordinated control and protection functions on products with a single structure, and can replace circuit breakers (fuse), contactors, overload (or overcurrent, phase failure) protection relays, starters, A variety of traditional discrete components such as isolators. KB0 is the first generation of CPS products in China. KB0 is mainly used in power systems with AC 50Hz (60Hz), rated voltage to 690V, and curr...
