Description
Technical field
It the utility model is related to power safety technique field, more particularly to a kind of RW types fuse switch protective grounding dress
Put.
Background technology
RW types fuse switch is applied to high-tension line, its common installation and pole type transformer high-pressure side, transformer and
On capacitor and junction and high-tension line end or branched line, its effect prevents load overload, transformer short-circuit
When damage high-voltage line and support circuit net, deenergization during daily change platform maintenance, make there is one to be evident that cut-off point therebetween.
Investigation finds that RW types fuse switch when daily change platform overhaul, pulls open switch, progress electrical verification, hanging earthing conductor,
But fuse switch can not hanging earthing conductor, can only mount with transformer high-voltage pile crown or arrester, influenceing operation area
Domain, to hang difficulty big, easy to fall off.
The content of the invention
The utility model embodiment provides a kind of RW types fuse switch protective earthing device, to solve prior art
In exist fuse switch can not hanging earthing conductor, can only be mounted at transformer high-voltage pile crown or arrester, influence operation
Region, big, the caducous problem that hangs difficulty.
The utility model embodiment provides a kind of RW types fuse switch protective earthing device, including：Fixation connecting rod, consolidate
Determine frame, conductor plate and grounding body carry portion；Fixed connecting rod is rectangle patch conductor, and middle part sets mounting hole；Fixed mount is
Inverted U-shaped conductor, fixed mount bottom is by conductor disc seal, and the angle of plane and plane where fixed mount is 45 where conductor plate
Degree, grounding body carry portion is hollow triangular-prism conductor, is socketed on conductor plate, and inner upper side edge is fixedly connected on conductor plate,
Conductor plate overlaps with the high line of triangular prism, and two waists of triangular prism are the cambered surface to concave；Fixed connecting rod is with fixed mount positioned at same
Plane, it is fixedly connected on fixed mount upper end；Insulating barrier is set outside fixed mount；Fixed connecting rod, fixed mount, conductor plate and ground connection
Body carry portion outer surface anticorrosion with painting coating；Insulated in use, fixed connecting rod is fixed on RW types fuse switch by nut
On the wire connecting bolt of sub- lower section.
Preferably, insulating barrier is 3M high-voltage isulation adhesive tapes.
The utility model beneficial effect includes：Disposably drop bar can be mounted successfully so that staff is overhauling
During RW type fuse switches, safety guarantee can be obtained, large-area power-cuts will not be caused to overhaul, mounting contact area is big, leads
Good electrical property, mount more firm stable, will not rock back and forth, it is difficult for drop-off and be not easy and other ground connection linear contact lays.

Embodiment
In order to be given at the implementation that ground wire is hung on RW type fuse switches, the utility model embodiment provides
A kind of built-in water route mineral hot furnace bell, is illustrated below in conjunction with Figure of description to preferred embodiment of the present utility model.
Refering to shown in Fig. 1, Fig. 2 and Fig. 3, the utility model embodiment provides a kind of RW types fuse switch protective grounding
Device, it is characterised in that including：Fixed connecting rod 1, fixed mount 2, conductor plate 3 and grounding body carry portion 4；Fixed connecting rod 1 is length
Square patch conductor, middle part set mounting hole；Fixed mount 2 is inverted U-shaped conductor, and the bottom of fixed mount 2 is sealed by conductor plate 3, led
The angle of the place plane of body plate 3 and the place plane of fixed mount 2 is 45 degree, and grounding body carry portion 4 is hollow triangular-prism conductor, socket
On conductor plate 3, inner upper side is along being fixedly connected on conductor plate 3, and conductor plate 3 overlaps with the high line of triangular prism, triangular prism
Two waists are the cambered surface to concave；Fixed connecting rod 1 is generally aligned in the same plane with fixed mount 2, is fixedly connected on the upper end of fixed mount 2；It is fixed
The outside of frame 2 sets insulating barrier；Fixed connecting rod 1, fixed mount 2, conductor plate 3 and the outer surface anticorrosion with painting of grounding body carry portion 4 apply
Layer；In use, fixed connecting rod 1 is fixed on the wire connecting bolt below RW type fuse switch insulators by nut.
Preferably, insulating barrier is 3M high-voltage isulation adhesive tapes.
In use, angle during installation is as shown in figure 3, the wire tie point below RW type fuse switch insulators is
One L-type angle bar, the both sides of L-type angle bar are in 135 degree, horizontal on one side, if the side be located at the negative semiaxis of x-axis, another side is located at the
The minus 45 degree of angles of four-quadrant；Fixed connecting rod 1 is fixed on galvanized bolt by nut, now the plane and L-type where fixed mount 2
The another side of angle bar overlaps, and now, conductor plate 3 is nearly vertical, and the bayonet socket of drop bar is just stuck in grounding body carry portion 4 downwards,
The both sides of grounding body carry portion 4 have the radian to concave, the bayonet socket outwardly convex of drop bar, and the shape of grounding body carry portion 4 to coincide,
After mounting, up to more than percent 90, electric conductivity maximizes contact area.Fixed mount 2 is played a supporting role, additionally it is possible to prevents from tearing open
Except when manpower cross senior general's drop bar and encounter live part, it is not easy to allow drop bar to rock back and forth, and the contact of other electrical body.
