Embodiment Construction
[0015] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.
[0016] Such as Figure 1 to Figure 3 As shown, an electrically operated interlocking mechanism includes an interlocking plate 1, an electric mechanism 2, a pressure plate 3, a micro switch 5 and a locking electromagnet 7. The electric mechanism 2 is provided with a slider 6, and the interlocking plate 1 There is a chute 8 matching the shape and size of the slider 6, a micro switch 5 is fixed on the motor mechanism 2 below the interlock plate 1, and a lock is fixed on the motor mechanism 2 above the interlock plate 1. Electromagnet 7, described interlocking plate 1 is provided with pressing plate 3, and described interlocking plate 1 is guided by slide block 6...

The invention discloses an electrically operated interlocking mechanism, which comprises an interlocking plate, an electrically operated mechanism, a pressing plate, a micro switch and a locking electromagnet, wherein the electrically operated mechanism is provided with a sliding block, the interlocking plate is provided with a sliding slot matched with the sliding block in shape and size, the micro switch is fixed on the electrically operated mechanism below the interlocking plate, the locking electromagnet is fixed on the electrically operated mechanism above the interlocking plate, the pressing plate is arranged on the interlocking plate, and the interlocking plate can move up and down under the guidance of the sliding block and fixation of the pressing plate so as to open or close an operating shaft hole of the electrically operated mechanism. The interlocking mechanism designed according to the invention has the advantages of simple structure, convenient and reliable operation, high safety, easy installation and debugging and the like, and realizes the interlocking between manual and electric operations of the electrically operated mechanism and the interlocking between an electric operation of an isolating switch and an upstream circuit breaker, thereby meeting five-prevention requirements of a switch cabinet, greatly reducing the occurrence probability of accidents, andbringing convenience for the production and life of people.
Description
technical field [0001] The invention relates to the technical field of switch cabinets, in particular to an electrically operated interlocking mechanism. Background technique [0002] Medium voltage 4000A and above high current fixed switchgear isolating switch operating force is very large, manual operation is very inconvenient, generally using electric operating mechanism to achieve, but there will be problems in the operation sequence and related interlocking when using electric operating mechanism . The existing interlocking mechanism has potential safety hazards, which is not conducive to the safety, continuity and stability of power supply, and brings unstable factors to production and life. [0003] Therefore, it is urgent to create a device that can solve the above problems, reduce the probability of accidents, and bring convenience to people's production and life. Contents of the invention [0004] The purpose of the present invention is to provide a new type of...
