Description
Technical field
The utility model relates to a kind of electrical switchgear, relates in particular to a kind of automatic change-over transmission mechanism.
Background technology
At present single the electromagnet of utilization that uses is as the transmission mechanism of the automatic change-over (being called for short ATS) of operational power, and commonly used have following two kinds of structures, as depicted in figs. 1 and 2.
Seeing earlier shown in Fig. 1, is the structural representation of existing a kind of transmission mechanism.Its working method is as follows: at first, electromagnet 11 work, adhesive armature 12, armature 12 drive pull bar 19 motions.Pull bar 19 is connected on the load axis 15, and under the pulling of pull bar 19, load axis 15 rotates around axle 18.So the pin 14 that is positioned on the load axis is stirred moving contact frame 13 rotations, as shown in the figure, one elongated slot is arranged on the moving contact frame 13, and pin 14 was placed on an indentation, there on elongated slot top originally, because the rotation of load axis 15, pin 14 will slip in the elongated slot, thereby moving contact frame 13 is rotated.Because load axis 15 is connected with stabilizer 16, load axis 15 rotations can cause stabilizer 16 to rotate together, under the help of the auxiliary switch 17 that links to each other with stabilizer 16, just can realize the conversion of automatic change-over.The advantage that adopts the transmission mechanism of this structure is that auxiliary switch 17 directly cooperates with load axis 15, and is simple in structure; Shortcoming is that stabilizer 15 is separated with moving contact frame 13, and impulsive force is big during conversion, and contact vibrates easily.
Fig. 2 is the structural representation of another kind of transmission mechanism.The course of work of Fig. 2 is as follows: at first, electromagnetic actuation armature 21, thus drive pull bar 22 motions.Pull bar 22 is connected on the swivel mount 23, pull bar 22 pulling swivel mounts 23 rotate, make in the elongated slot of pin 28 on moving contact frame 24 on the swivel mount 23 and slide, in this structure, moving contact frame 24 is connected as a single entity with stabilizer, but the elongated slot on the moving contact frame 24 that do not draw among the figure rotates owing to the slip of pin 28 drives moving contact frame 24 (comprising stabilizer), finishes the conversion of automatic change-over under the help of auxiliary switch 26.The advantage of this structure is that moving contact frame 24 is connected as a single entity with stabilizer, and moment of inertia is big; Its shortcoming is that auxiliary switch 26 is to separate with entire mechanism, and they connect by connecting rod 25, but have so just reduced reliability of products.
Because these two kinds of structures have merits and demerits separately, if their advantages can be got up, just can make transmission mechanism have more performance.
