Description
Technical field
This utility model belongs to motor switch technical field, is specifically related to one and makes at rolling stock top
Electric isolating switch.
Background technology
Disconnecting switch is widely used in the main circuit of the rolling stock such as railway locomotive and EMUs, is arranged on
Its roof.Its Main Function is the operating condition optimizing high pressure equipment, when roof apparatus breaks down
Time, trouble point can be isolated, maintain locomotive and the safe operation of EMUs, reduce because of roof apparatus therefore
The accident of locomotive defect hindered and cause, it is ensured that the safe operation of vehicle.Railway locomotive and EMUs are main at present
Using Pneumatic isolating switch, but the impact of Pneumatic isolating switch climate is relatively big, structure is complicated, zero
Parts are many, cause its fault rate higher.
Utility model content
The purpose of this utility model is to provide a kind of electric isolating switch used at rolling stock top,
Solve structure complexity and bigger the asking of impact of climate factor that existing Pneumatic isolating switch exists
Topic.
This utility model be the technical scheme is that a kind of rolling stock top use electronic every
Leaving pass, including rotating insulated son and fixed insulation, the top of fixed insulation connects has contact to press from both sides,
The top of rotating insulated son connects moving conductive rod, and the radius of turn of moving conductive rod is not less than rotating insulated
Centre-to-centre spacing between son and fixed insulation, rotating insulated son is fixed on final drive shaft, also includes leading to
Cross the reductor shaft of bonded motor and speed reducer, final drive shaft and reductor by the most sheathed
Gear is connected with each other, and final drive shaft is also arranged with cam, and cam stirs auxiliary contact, and motor also connects
It is connected to catalyst.
Feature of the present utility model also resides in,
Also include that mounting base, rotating insulated son and fixed insulation may be contained within described mounting base.
Contact folder is secured by bolts on fixed insulation.
The beneficial effects of the utility model are: of the present utility model a kind of in the use of rolling stock top
Electric isolating switch solves structure complexity and the climate factor that existing Pneumatic isolating switch exists
Affect bigger problem.A kind of electric isolating switch used at rolling stock top of the present utility model
For locomotive at the isolated operation dropped under arciform state, can be carried out after its energising point, closing operation, transport
The impact of row state climate is less, simple and reliable for structure, parts are few, failure rate is low, it is ensured that therefore
Barrier security appliance and the safe operation of rolling stock.

Detailed description of the invention
With detailed description of the invention, this utility model is described in detail below in conjunction with the accompanying drawings.
The structure of a kind of electric isolating switch used at rolling stock top that this utility model provides is such as
Shown in Fig. 1-Fig. 3, including rotating insulated sub 1 and fixed insulation 2, the top of fixed insulation 2 is even
Being connected to contact folder 4, the rotating insulated top of sub 1 connects moving conductive rod 3, the rotation of moving conductive rod 3
Radius is not less than the centre-to-centre spacing between rotating insulated sub 1 and fixed insulation 2, and rotating insulated sub 1 is solid
On final drive shaft 5, also include by bonded motor 9 and reductor 8, final drive shaft 5 He
The reductor shaft 7 of reductor 8 is connected with each other by the most sheathed gear 6, final drive shaft 5 and subtracting
Speed arbor 7, by gear 6 driving torque, final drive shaft 5 is also arranged with cam 12,12 groups, cam
Dynamic auxiliary contact 11, motor 9 is also associated with catalyst 10.
A kind of electric isolating switch used at rolling stock top of the present utility model also includes installing the end
Plate 13, rotating insulated sub 1 and fixed insulation 2 can be secured by bolts on mounting base 13.
Contact folder is secured by bolts on fixed insulation.
During work, catalyst 10 and auxiliary contact 11 are all connected with rolling stock managing and control system, when
Motor 9 obtains electric after being divided the instruction of (conjunction) lock simultaneously, and catalyst 10 is corresponding by adhesive (release)
Controlling motor 9 just (instead) to turn, just (instead) the turning of motor 9 converts electric energy to mechanical energy and (i.e. turns round
Square) drive reductor 8 to rotate, 8 moments of torsion of reductor are sent to after being amplified by internal structure slow down
On arbor 7, reductor shaft 7 drives final drive shaft 5 to rotate by gear 6, and final drive shaft 5 carries again
The contact folder 4 that dynamic rotation 1 insulator and moving conductive rod 3 rotate with fixed insulation 2 contacts or divides
From, so that a kind of electric isolating switch used at rolling stock top of the present utility model is carried out point,
Closing operation, stirs auxiliary contact 11 when being rotated by final drive shaft 5 band moving cam 12 so that auxiliary is touched
11 are opened or closed, thus realize to rolling stock managing and control system display rolling stock top electronic
Disconnecting switch be opened or closed signal.
