Description
Technical field
The utility model relates to a kind of technical field of isolating switch, the transmission device of specifically a kind of angle type isolating switch.
Background technology
Isolating switch is a visual plant in the gas insulated metal enclosed swit chgear, and it connects the effect of other unit in addition except the function that realizes standard code, and consumption is very big in GIS equipment.Isolating switch subangle type isolating switch and line style isolating switch, traditional angle type isolating switch all adopts the connecting lever transmission, the connecting lever box need be installed on the isolating switch housing, at least need to install additional two connecting levers and a cover connecting lever connecting rod, complicated integral structure, have long kinematic chain, the scale error of each member and the gap in the kinematic pair will make linkage produce bigger accumulated error, reduce transmission efficiency; In addition, because the connecting lever transmission is actually interface and rotates around the connecting lever axle center, the free track of interface is circular arc rather than straight line, but the moving contact that connects with connecting lever in using must be a rectilinear motion, movement locus for the restriction interface, usually need in structure, install guide post additional, like this, though moving contact is done rectilinear motion under the restriction of guide post, but certainly exist bigger frictional resistance between the two, consume part mechanical energy, also structure itself has been had certain impact, influenced useful life.
Summary of the invention
In order to overcome above-mentioned defective, it is a kind of simple in structure, compact that the utility model provides, transmission efficiency height, the transmission device of the angle type isolating switch of stable performance.
The technical solution adopted in the utility model is: the transmission device of a kind of angle type isolating switch, comprise insulating bar, leading screw, hold-down nut, bracing frame and positioning sleeve, leading screw is provided with hold-down nut, leading screw and hold-down nut are arranged on positioning sleeve inside along the housing axis, positioning sleeve is axially disposed within the housing center by bracing frame, one end of leading screw is fixedlyed connected with insulating bar, the other end of insulating bar is connected by the outer mechanism of internal spline and housing, moving contact is placed in the leading screw outside and stretches into positioning sleeve inside fixedlys connected with hold-down nut, be provided with the watchband fingertip in the positioning sleeve, the aperture surface of watchband fingertip is connected with moving contact.
Be provided with the stroke limit piece of moving contact in positioning sleeve inside.
The outside at positioning sleeve also is provided with radome.
The utility model has saved the connecting lever box, and mechanism can be directly installed on the isolating switch housing by flange, can dwindle the size of isolating switch, makes compact conformation; Adopt leading screw as transmission device, the transmission efficiency height, mechanical loss is little, utilizes positioning sleeve to guarantee that the moving contact motion reaches for rectilinear motion and the concentricity of housing, has improved the resistance to overturning of isolating switch.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Now in conjunction with the accompanying drawings the utility model is further described, Fig. 1 is a kind of embodiment of the present utility model, mainly comprise insulating bar 1, leading screw 2, hold-down nut 3, bracing frame 4 and positioning sleeve 5, leading screw 2 is provided with hold-down nut 3, leading screw 2 and hold-down nut 3 are arranged on positioning sleeve 5 inside along the housing axis, and hold-down nut 3 can move axially in positioning sleeve 5 along leading screw 2.Positioning sleeve 5 is axially disposed within the housing center by bracing frame 4, and an end of leading screw 2 is fixedlyed connected with insulating bar 1, and the other end of insulating bar 1 is connected by the outer mechanism of internal spline and housing.Moving contact 6 is placed in leading screw 2 outsides and stretches into positioning sleeve 5 inside fixedlys connected with hold-down nut 3, and moving contact 6 can drive lower edge leading screws 2 at hold-down nut 3 and move axially.Be provided with the watchband fingertip in the positioning sleeve 5, the watchband fingertip in the form of a ring, the aperture surface of watchband fingertip is connected with moving contact 6, the watchband fingertip can import electric current or derive moving contact 6.Be provided with the stroke limit piece of moving contact 6 in positioning sleeve 5 inside, guide vane end stop is used for limiting branch, the closing position of moving contact 6 can not the excess of stroke.The outside at positioning sleeve 5 also is provided with radome, and radome and conductor are that equipotential arranges that the curved profile that radome is smooth can make the electric field line between conductor and the external shell more even, avoids point discharge.
The utility model drives insulating bar 1 by mechanism and leading screw 2 rotates, and makes hold-down nut 3 axial linear movement in positioning sleeve 5, and hold-down nut 3 drives moving contact 6 moving linearly vertically simultaneously, thereby realizes branch, the closing operation of moving contact 6.
This shows, the utlity model has simple in structure, compact, transmission efficiency height, the characteristics such as stable performance.
