Detailed Description
In order to make the technical solutions of the present invention better understood by those skilled in the art, the present invention will be further described in detail with reference to the accompanying drawings and preferred embodiments.
As shown in the figure, the utility model comprises a grounding position 11, an isolation position 12, a working position 13, a movable contact 1, an adjusting device and a manual unlocking device, the adjusting device comprises two oppositely arranged working position electromagnetic locks 6, a grounding position electromagnetic lock 7 and a locking cam 4 arranged between the working position electromagnetic locks and the grounding position electromagnetic lock, the locking cam 4 comprises a cam body 14 and two protrusions 15 arranged on the side of the cam body 14, one end of the moving contact 1 is hinged with the lower end of a connecting rod 16, the upper end of the connecting rod 16 is connected with a transmission shaft 3, the transmission shaft 3 is connected with the locking cam 4, the locking cam 4 is driven by the motor 2 at the upper end, the manual unlocking device comprises two opposite unlocking units, the unlocking units comprise manual rods 8, knobs 17 arranged at the upper ends of the manual rods 8 and chain connecting rods 5 arranged at the lower ends of the manual rods 8, the other end of the link rod 5 is arranged on the working position electromagnetic lock 6 or the grounding position electromagnetic lock 7.
When moving contact 1 stops at ground connection position 11, after providing the isolation position signal that turns to, 6 attractions of position electromagnetic lock in work, the electromagnetic lock pole is taken out, separate with shutting cam 4, relieve the shutting, motor 2 begins to rotate simultaneously, drive shutting cam 4 and connecting rod 16 rotate, moving contact 1 is gone to isolation position 12, protruding portion 15 and ground connection position electromagnetic lock pole butt this moment, provide the backstop function of crossing, after moving contact 1 targets in place, motor 2 stall, 6 releases of position electromagnetic lock in work, the electromagnetic lock pole stretches out, with shutting cam 4 slip butt, the locking of 1 both sides of moving contact.
If from isolation position 12 to work position 13, work position electromagnetic lock 6 and the actuation of ground connection position electromagnetic lock 7, the electromagnetic lock pole is taken out, from 4 separation of shutting cam, remove the shutting, motor 2 begins to rotate simultaneously, drive shutting cam 4 and connecting rod 16 rotate, moving contact 1 rotates to work position 13, locate the dog 10 and the 9 butt of backstop post at connecting rod middle part this moment, provide the backstop function of excessive position, when moving contact 1 targets in place the back, work position electromagnetic lock 6 and the 7 releases of ground connection position electromagnetic lock, the electromagnetic lock pole stretches out, with 4 slip butts of shutting cam, 1 both sides locking of moving contact.
And on the contrary, the grounding position electromagnetic lock is attracted to unlock, the movable contact 1 rotates, and the grounding position electromagnetic lock 7 is released to lock. And the locking function is ensured to be realized when the two sides of the moving contact 1 rotate at each position.
When manual unlocking is needed, the manual rod is rotated to the unlocking position by the knob 17 at one end of the manual rod 8 to drive the link rod 5 to rotate, the other end of the link rod 5 is connected to the electromagnetic lock, and the link rod 5 moves to drive the electromagnetic lock rod to move to the suction position so as to unlock the electromagnetic lock; when the moving contact 1 is in place, the manual lever 8 is rotated to a locking position, the electromagnetic lock rod falls back to lock the contact, and the moving contact 1 moves in accordance with unlocking, locking logic and electric operation.
