When switch needs are adjusted in "on" position, after the assembling of grounding lead shaft rotates clockwise specified angle, ground connection
The assembling of axle divide-shut brake spring produces pulling force and continues to cause the ground connection main shaft to rotate, and ground connection blade is connected with arc-chutes static side
Lower contact be separated, make grounding switch be in point position.
The divide-shut brake of the embodiment of the present application breaker in middle be by VSP5 electromagnetic springs operating mechanism by transmission, drive main shaft and
Isolation axle is rotated so as to realized, and VSP5 electromagnetic spring operating mechanisms are a machinery and the transmission module for electrically combining, and are
The source of switch divide-shut brake power.During electromagnetic spring operating mechanism action, main shaft with isolate axle almost and meanwhile action (therebetween
Action have a small time difference).Main axis make the epoxy connecting lever of main shaft upper molding push/pull up, so that
The dynamic and static contact of arc-chutes or separation, isolation axle is rotated makes isolation knife couple with the assembling of upper touch base and separate.
Main axis cause the three-phase epoxy connecting lever on main shaft to push, and upper touch base assembling is with isolation knife according to corresponding three-phase
Module position is coupled, and the moving contact in arc-chutes is contacted with static contact, and switch is in "on" position;
Main shaft is rotated backward causes three-phase epoxy connecting lever pull-up, arc-chutes be flexible coupling according to corresponding three-phase component
Position is separated, and the assembling of upper touch base departs from according to corresponding three-phase module position with isolation knife, the moving contact in arc-chutes and
Static contact is separated, and switch is in gate-dividing state.
It should be noted that the one end that is flexible coupling is connected with the conducting block of movable end of arc extinguishing chamber all the time, the other end all the time with every
It is connected from knife, it plays an interconnection function of the major loop when closing a floodgate so that major loop forms path.Meanwhile, switch
When divide-shut brake, displacement when vacuum interrupter moving contact is moved up and down can by be flexible coupling itself deformation and absorb.From
And the malformation that avoids causing using hard connecting mode and destruction.
The embodiment of the present invention proposes a kind of double-fracture vacuum load switch, and the switch includes switch frame, isolated part, master
Shaft portion, grounded part, main shaft portion include that main shaft and lower bracing frame assembling, isolated part include upper support frame assembling, isolation
Spindle mounted, upper support frame assembling include that touch base is assembled, and isolation spindle mounted includes isolation knife assembling and is flexible coupling, lower support
Rack-mounted with include arc-chutes, when switch in closing position when, the dynamic and static contact of arc-chutes contacts, and isolation knife is assembled with upper touch base
It is coupled, isolation knife is connected by being flexible coupling with the conducting block of movable end of arc extinguishing chamber, and conducting block is connected with the moved end of arc-chutes, from
And the path in whole loop is realized, when switch is in sub-gate position, inside arc-chutes, dynamic and static contact is separated, and forms a vacuum
Fracture, isolation knife are separated with upper touch base, are formed an isolation fracture, are therefore switched and define double break mouth structure in separating brake, i.e.,
Make in the case where structure is very compact, it is also possible to meet the insulating requirements of high load capacity electric pressure switch.
