Abstract
The utility model relates to an aerify load switch for cabinet. Main solve current load switch when using, the moving contact station will bear the destruction of axial force, leads to mechanical strength to reduce, reduces machinery and electrical life, and the low technical problem of capacity. This load switch includes pivot (1), explosion chamber (2), its characterized in that: still include cross arm (3), cross arm (3) are the frame form, tip (31) and side (32) of both sides including both ends, pivot (1) is fixed in tip (31) of cross arm (3) and can drives main shaft (6) rotatoryly, cross arm (3) are placed in explosion chamber (2) for a plurality of and along the axial of pivot (1) in, just explosion chamber (2) and cross arm (3) fixed connection. This aerify load switch for cabinet is through the structural design to the moving contact mounting means to increase mechanical strength, increase machinery and electrical life, simple easy installation, and the axial distance between the moving contact is adjustable, the increase capacity.
Description
Technical field
This utility model belongs to switching technique field, particularly relates to a kind of gas-filling cabinet on-load switch.
Background technology
SF6 on-load switch is a kind of to have the insulation of excellence, arc extinction performance, it is possible to meet close, isolate, ground connection three station
The switchgear of function.Have simple in construction, interlocking is reliable, volume is little, maintenance less, the advantage such as safety easily installation, it is adaptable to no
Same application scenario.Can preferably protect transformator owing to SF6 on-load switch coordinates with limiting fuse, oneself obtains general abroad
All over using.Along with Urban Net Construction and the development that deepens continuously of transformation, load switch equipment is at the ring network power supply of 12kV distribution system
Application with terminal power transmission also gets more and more.
At present, existing SF6 on-load switch in use, the destruction of moving contact station axial force to be born, cause machinery
Intensity reduces, and reduces machinery and electrical endurance, and installs inconvenience, it addition, the finite capacity of product.
Utility model content
In order to overcome shortcoming and the weak point of background technology, this utility model provides a kind of gas-filling cabinet on-load switch,
Solve existing on-load switch in use, the destruction of moving contact station axial force to be born, cause mechanical strength to reduce, reduce machine
Tool and electrical endurance, and the technical problem that capacity is low.
The technical solution of the utility model is: a kind of gas-filling cabinet on-load switch, including rotating shaft, arc-chutes, also includes horizontal stroke
Load, described cross-arm is frame-shaped, and including end and the side of both sides at two ends, described cross-arm is frame-shaped, including two ends end and
The side of both sides, described rotating shaft is fixed on the end of cross-arm and main shaft can be driven to rotate, and described arc-chutes are several and edges
Axially being built in cross-arm of rotating shaft, and described arc-chutes are fixed with cross-arm and are connected.
Described arc-chutes towards rotating shaft axially and can horizontal sliding along the side of cross-arm so that between arc-chutes
Axial distance is adjustable.
The side of described cross-arm is provided with the hole, location along horizontal direction distribution, and described arc-chutes pass through securing member and location
Match and be fixed on side in hole.
Described arc-chutes are annular, and described arc-chutes are provided with gathering sill, and described gathering sill snaps in the side of cross-arm, described
Arc-chutes pass through gathering sill along described side sliding.
This utility model has the advantages that this gas-filling cabinet on-load switch is by the knot to moving contact mounting means
Structure designs, and makes the axial distance between moving contact adjustable, thus increases mechanical strength, increases capacity, and it is mechanical and electric to increase
The gas life-span, simple easily installation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, rotating shaft 1, arc-chutes 2, cross-arm 3, end 3, side 32, position hole 4, gathering sill 5, main shaft 6.
Detailed description of the invention
Below for accompanying drawing, embodiment of the present utility model is described further:
As it can be seen, a kind of gas-filling cabinet on-load switch, including rotating shaft 1, arc-chutes 2 and cross-arm 3, described cross-arm 3 is
Frame-shaped, including end 31 and the side 32 of both sides at two ends, described rotating shaft 1 is fixed on the end 31 of cross-arm 3 and can drive master
Axle 6 rotates, and described arc-chutes 2 are several and being axially built in cross-arm 3 along rotating shaft 1, and described arc-chutes 2 and cross-arm
3 fixing connect, described arc-chutes 2 towards rotating shaft 1 axially and can horizontal sliding along the side of cross-arm 3 so that arc-chutes 2
Between axial distance adjustable.By the contact of three stations is installed in arc-chutes, it is possible to effectively reduce axial destructive power
Can slide to regulate distance each other along cross-arm between impact on contact, and each station, according to such scheme, should
Gas-filling cabinet on-load switch is by designing the structure of moving contact mounting means, and makes the axial distance between moving contact can
Adjust, thus increase mechanical strength, increase capacity, increase machinery and electrical endurance, the most easily install.
In this utility model, the side of described cross-arm 3 is provided with the hole, location 4 along horizontal direction distribution, described arc extinguishing
Room 2 is passed through securing member and is fixed on side 32 with positioning hole 4 and matching.By arranging hole, location on the side of cross-arm, each dynamic
Being equipped with the hole, location of multiple horizontal distribution at contact station, when regulation, first loosening fasteners, mobile contact station is with regulation
Distance each other, is matched with hole, location by securing member so that moving contact station is fixed on cross-arm the most again.Regulation
Convenient, stability is strong.
In this utility model, described arc-chutes 2 are annular, and described arc-chutes 2 are provided with gathering sill 4, described gathering sill 5
Snapping in the side 32 of cross-arm 3, described arc-chutes 2 pass through gathering sill 5 along the sliding of described side 32.By at moving contact station two
Side arranges gathering sill, and after arc-chutes load in cross-arm, the gathering sill of its both sides snaps in the side of cross-arm, so that arc-chutes exist
During slip, it is possible to coordinate to realize the stability guided with side sliding by gathering sill, increase stability during regulation.
In this utility model, described cross-arm 3 is integral type structure.The side of cross-arm and end are integral type structure, increase
Add intensity, thus be effectively increased electrical endurance.
