For reaching above-mentioned purpose, solution of the present utility model is:
A kind of Mobile vacuum load switch and fuse combined electric apparatus, including handcart, propulsive mechanism, switch operating mechanism, insulating polar pole, upper contact arm, lower contact arm, vacuum interrupter, fuse and trip link mechanism；Insulating polar pole is arranged on handcart, and handcart arranges propulsive mechanism, and propulsive mechanism orders about handcart and moves；Upper contact arm is arranged on insulating polar pole upper end, and fuse is placed in contact arm, and lower contact arm is arranged in the middle part of insulating polar pole, and vacuum interrupter is arranged between fuse and lower contact arm, forms " F " type cascaded structure；The moved end of vacuum interrupter is connected with lower contact arm and is connected with the Partner of switch operating mechanism by insulated tension pole, switch operating mechanism is arranged on insulating polar pole, the drive end of switch operating mechanism links with trip link mechanism, it is relative with the shock end of fuse that trip link mechanism is arranged on insulating polar pole upper end, fuse blows action, the shock end of fuse orders about trip link mechanism action.
Further, trip link mechanism is set to " V " type swing arm, the first arm and second arm one end connect and is formed, and end is swingable is arranged on insulating polar pole upper end in connection, first arm is relative with the shock end of fuse, and the second arm is connected with the drive end of switch operating mechanism by connecting rod.
After using such scheme, this utility model maintenance and replacing fuse can be carried out outside cabinet, do not affect the operation of other switch cubicle, it is possible to greatly shorten unnecessary power off time in backup circuit breaker pushes maintenance cabinet.
Using integrated design, switch operating mechanism and propulsive mechanism are respectively adopted model structural design, overall structure advantages of simple.
Vacuum interrupter is arranged between fuse and lower contact arm, forms " F " type series arrangement, and fuse is arranged on the top of vacuum interrupter, and when properly functioning, vacuum interrupter is also in the protection domain of fuse.
Fuse is horizontally disposed in upper contact arm insulating cylinder, and the two ends of its insulating cylinder all leave louvre so that fuse dispels the heat,
The conventional universal product selected by fuse, meets easy spare unit and easily exchanges.
Switch operating mechanism is directly connected with the moved end of arc-chutes, decreases transmission link, makes on/off switch operation is simple and reliable stable.

Detailed description of the invention
Below in conjunction with drawings and the specific embodiments, this utility model is described in detail.
Refering to shown in Fig. 1 and Fig. 2, a kind of Mobile vacuum load switch of this utility model announcement and fuse combined electric apparatus, including handcart 1, propulsive mechanism 2, insulating polar pole 3, switch operating mechanism 4, upper contact arm 51, lower contact arm 52, vacuum interrupter 6, fuse 7 and trip link mechanism 8.
Insulating polar pole 3 is arranged on handcart 1, and handcart 1 arranges propulsive mechanism 2, and propulsive mechanism 2 orders about handcart 1 and moves, and propulsive mechanism 2 and handcart are existing structure, and its concrete structure does not repeats.
Upper contact arm 51 is arranged on insulating polar pole 3 upper end, and fuse 7 is placed in contact arm 51, and lower contact arm 52 is arranged in the middle part of insulating polar pole 3, and vacuum interrupter 6 is arranged between fuse 7 and lower contact arm 52, forms " F " type cascaded structure.Fuse 7 can be current-limiting fuse.Fuse 7 is arranged on the top of vacuum interrupter 6, and when properly functioning, vacuum interrupter 6 is also in the protection domain of fuse 7.
The moved end of vacuum interrupter 6 is connected with lower contact arm 52, the moved end of vacuum interrupter 6 is connected also by the Partner of insulated tension pole 9 with switch operating mechanism 4, switch operating mechanism 4 is arranged on insulating polar pole 3, the drive end of switch operating mechanism 4 links with trip link mechanism 8, it is relative with the shock end 71 of fuse 7 that trip link mechanism 8 is arranged on insulating polar pole 3 upper end, fuse 7 fusing, the shock end 71 of fuse 7 orders about trip link mechanism 8 action.Switch operating mechanism 4 is existing conventional structure, and its concrete structure does not repeats.
In the present embodiment, trip link mechanism 8 is set to " V " type swing arm, it is connected with second arm 82 one end by the first arm 81 and is formed, connect that end is swingable is arranged on insulating polar pole 3 upper end, first arm 81 is relative with the shock end 71 of fuse 7, and the second arm 82 is connected with the drive end of switch operating mechanism 4 by connecting rod 83.
Insulating polar pole 3 uses epoxide resin material APG pouring technology, improves product insulating properties, and the primary conductive part of every phase is all enclosed in cylinder, substantially increases anti-filthy ability.Propulsive mechanism 2 is arranged on before switch so that switch operates more humane when coordinating with cabinet, and operator can be operated directly facing propulsive mechanism 2, has iron dividing plate between operator and pole, and plate has observation window.
When this utility model uses, switching-in spring energy storage；Energy storage has two ways, electronic and manual, and manual energy storage is to be inserted in energy storage hole by stored energy operation handle, swings complete to energy storage when hearing the sound of " click ".Electric energy-stored is to plug in, and switches on power, motor complete switching-in spring energy storage, and after energy storage, electric motor loop disconnects automatically, it is possible to after combined floodgate again energy storage to realize reclosing function.
Energising connect secondary control loop, make making electromagnet action, switching-in spring release energy the actions such as band moving cam, connecting rod realize close a floodgate, simultaneously also to tripping spring energy storage, to tactile bucket contact spring energy storage, get ready for separating brake, it is possible to hand push button carries out closing operation.
Sub-switching operation；After electronic tripping electromagnet energized action, closing magnet master part is threaded off, and tripping spring releases energy, contact spring releases energy, and drives arc-chutes moving conductive rod to move downward, completes sub-switching operation, it is possible to hand push button carries out closing operation.
Arc-chutes disjunction is driven to thread off during fuse blows；When fuse runs, if primary circuit makes its arbitrary phase fuse blows action by fault current, fuse clashes into end (clashing into length 26) and clashes into dropout trace mechanism and drive switch trip action, makes arc-chutes action separating brake, changes fuse tripping mechanism and automatically resets.
The foregoing is only preferred embodiment of the present utility model, not the restriction to this case design, all equivalent variations done according to the design key of this case, each fall within the protection domain of this case.
