Position, that is, positioned at the low order end of movement travel, repulsion dish are located at the low order end of closing dielectric chamber to the jacking block 18 on shackle rod,
The pulse power 10 is energized to first coil 91, and repulsion dish 90 produce inductive loop, the electric current side of inductive loop and first coil 91
To contrary, between repulsion dish 90 and first coil 91, produce repulsion, thus repulsion dish 90 drive shackle rod 19 and then drive is opened
Close pull bar 191 to left movement, wherein, the motor process of shackle rod is divided into two stages：First stage, due to through hole 610
Exist, at the motion initial stage of repulsion dish 90, the gases at high pressure of repulsion dish 90 direction of motion side can be discharged from damping through hole,
Gases at high pressure little and constant to the square active force of repulsion dish it is ensured that the high speed divide-shut brake motion of shackle rod, when using not
The branch wire time switching can be affected；Second stage, repulsion dish 90 move to damping through hole to the left, with the continuation of repulsion dish
Motion, the excircle of repulsion dish can gradually block damping through hole until closure damps through hole completely, during this section, damps through hole
Confession gases at high pressure discharge aperture less and less, the output of high-pressure buffer gas, is fewer and feweri, and gases at high pressure are to repulsion dish
90 counteracting force is increasing, increasing to the buffer-braking power of repulsion dish, so that the speed of repulsion dish is gradually reduced, until
The jacking block 18 of shackle rod contacts stop motion with the second stop block 121, that is, complete separating brake process, by such gas buffer
Achieve this repulsion operating mechanism when applying in high-speed switch, can quick acting switching-off, and extremely short after separating brake completes
Realize braking within discrete time, it is to avoid the collision of repulsion dish and first, second coil.In whole separating brake process, divide-shut brake
, in the motion early stage of repulsion dish, jacking block 18 is close to spacing collar, and limit spring is compressed for limit spring in maintaining body,
Switch lever drives jacking block when being moved through spacing collar to the left, and limit spring extends, switch lever move to jacking block with spacing
During fast 121 contact of block, limit spring can apply a retentivity to jacking block, and maintained switch pull bar is in open position；Close a floodgate
When, the pulse power 10 is energized to the second coil 92, produces repulsion, the motion of switch lever between the second coil 92 and repulsion dish 90
Process is contrary.
