On any groove in, make the shaft that can not rotate, when mechanism is from isolation (ground connection) to ground connection (isolation) conversion work state
When, the startup of electromagnet 20 makes shaft end retract unlock, and junction panel 17 turns to ground connection (isolation) under the leading of shifting shaft 22
Latched position, after rotateing in place, interlock switch 21 is depressed by the boss on junction panel 17,20 electricity of cut-out interlock circuit electromagnet
Source makes 20 shaft end of electromagnet reinsert and realizes locking in any groove on mechanical lock, while also making junction panel 17 in new position
Locking is set, at the same time 18 position of auxiliary switch is converted, and completes the conversion of control loop.
After motor 2 is cut off the power, since system is there are inertia, transmission mechanism will also operate a period of time, such as Fig. 6 institutes
Show, the present invention is additionally provided with buffer unit 23 in side of the master gear 8 far from two-way frid 10, effectively absorbs overshoot energy.Institute
It includes friction plate 24, spring 25 and adjustment bolt 26 to state buffer unit 23, and spring 25 is mounted on friction plate 24 far from master gear 8 one
Side, after rotation overshoots, the shifting shaft 22 on master gear 8, which acts on the friction plate 24, consumes inertia energy, the friction plate
24 position adjusts by adjusting bolt 26, can both adjust frictional force size in this way, whole system can also be made in specific bit
It sets and stops.
The operation principle of the present invention is that：
1, mechanism disconnecting switch (DS) operates
When mechanism divides position in isolation ground connection pair, after mechanism is connected to disconnecting switch after feed motion instruction, for controlling
The contactor 19 that DS processed closes a floodgate, which is attracted, connects the rotation of motor 2, and motor 2 passes through primary transmission gear set 3 and secondary transmission gear set 4
Transmission after, drive master gear 8 to rotate, when the shifting shaft 22 on master gear 8 enters in the sliding slot 27 on two-way frid 10, i.e.,
Two-way frid 10 is driven to rotate, the lead agency output shaft after the transmission of output gear group 12 by frid axis 11 of two-way frid 10
The 13 corresponding angles of output.When mechanism is connected to the instruction of DS separating brakes, the contactor 19 for controlling DS separating brakes acts, more than drive
Transmission system makes mechanism return to open position.
2, mechanism earthing switch (ES) operates
When mechanism is connected to the instruction of ES feed motions, the contactor 19 for controlling ES combined floodgates (is used to control DS separating brakes
Contactor 19) be attracted, motor 2 rotate, drive transmission system realize ES close a floodgate.When mechanism is connected to the instruction of ES separating brakes, it is used for
The contactor 19 (contactor 19 for being used to control DS combined floodgates) for controlling ES separating brakes is attracted, and motor 2 rotates, and transmission system is driven to make
Mechanism returns on open position.
3, mechanism interlock operating principle
When mechanism isolator operation, due to 21 equal cut-off loop of auxiliary switch 18 and interlock switch, electromagnet 20 is not
Action, reliably cuts off conversing circuits.When needing earthing switch to act, mechanism need to be converted to ground connection mode of operation, press ground connection
Switch knob is operated, so that control system control auxiliary switch 18 and interlock switch 21 is turned on circuit, mechanism driving is allowed to convert,
It is transformed to ground state, while in conversion process, the action unlock of electromagnet 20 makes the stirring on master gear 8 of junction panel 17
Under the leading of axis 22, ground connection latched position is turned to, after rotateing in place, interlock switch 21 is depressed by the boss on junction panel 17,
20 power supply of interlock circuit electromagnet is cut off, is relocked.Otherwise action process is the same.
