Abstract

The utility model discloses a general earth bar with adjustable, it has been solved prior art and has had that the usage is single, the operating difficulties scheduling problem, its characterized in that: it is by " U " type crotch (1) and insulator spindle constitutions such as (8), it presss from both sides (3) and shell fragment (4) for straight plane, both ends are curved movable wire to have set up the middle part in " U " type crotch (1) to set up earth connection terminal (2) at the one of which side arm, connected with insulator spindle (8) continuously through the activity. Have rational in infrastructure, convenient operation, strong adaptability, have advantage such as hidden danger safely, but ground connection and transmission line bare wire ground connection are arranged in transformer substation's bare wire, aluminium to the wide application, have good popularization and application and worth.

Description

Adjustable universal earth rod
One, technical field
The utility model belongs to power construction auxiliary equipment, relates in particular to a kind ofly be applicable to transformer station's bare wire, aluminium row's ground connection and the adjustable universal earth rod of transmission line plain conductor ground connection.
Two, background technology
At present, in most transformer station, bonding conductor mainly contains square type aluminium row and two kinds, round wire, and the earth rod used mainly contains T-shaped and U-shaped two kinds of versions, its wire clamp is fixedly connected with insulating rod, the angle of wire clamp is non-adjustable, U-shaped earth rod generally can not be used in square type aluminium row, and T-shaped earth rod wire clamp servo rotary in rotation rundown process, easily fall down from aluminium row, not easily find the hitch point of optimized suspension angle, particularly in switch cubicle, hang earth connection, insulating bar is longer to take up room, impact construction, use, inconvenient operation.
Three, summary of the invention
The purpose of this utility model is for market provides a kind of adjustable universal earth rod of rational in infrastructure, easy to use, strong adaptability, quick and safe.
The technical solution of the utility model is it is be made up of in described " U " type crotch parts such as " U " type crotch and insulating bars to be provided with the active wire folder and shell fragment that middle part is straight plane, two ends are curved, and be provided with earth connection terminal at one side arm, be connected with insulating bar by active joint.Described active joint is made up of top connection, lower contact and fastening bolt, top connection and lower contact one end are cylindrical, the other end is semi-cylindrical, semi-cylindrical side plane is the male and fomale(M&F) of rule, and on semicolumn, be provided with the adjustment slotted eye be fixedly connected with by fastening bolt, cylindrical end and " U " type crotch one side arm end connecting hole of top connection are fixedly linked, and the cylindrical end of lower contact is fixedly connected with insulating bar upper end.Described insulating bar lower end is provided with the interior screw connection hole connecting and extend insulating bar, is connected with insulating bar by the external screw thread being arranged on the upper end extending insulating bar.
The beneficial effects of the utility model are: not only rational in infrastructure, simple to operate, and the needs that the angle that power supply installation, maintenance personnel can be made to adjust arbitrarily wire clamp and insulating bar is fixedly connected with to adapt to diverse location wire and different conductor, thus effectively ensure that electric power overhaul personnel job safety is without hidden danger.
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Four, accompanying drawing explanation
Fig. 1 is the downward status architecture schematic diagram of the utility model crotch;
Fig. 2 is the utility model crotch level structural representation.
In figure: 1 is " U " type crotch, and 2 is earth connection terminal, 3 is active wire folder, and 4 is shell fragment, and 5 is top connection, and 6 is lower contact, and 7 is fastening bolt, and 8 is insulating bar, and 9 is interior screw connection hole, and 10 is external screw thread, and 11 for extending insulating bar.
Five, embodiment
As shown in Figure 1, insulating material to be asked for according to electrical safety regulations for technical operation make insulating bar 8 and extend insulating bar 11, get metal material and make " U " type crotch 1, and in " U " type crotch 1, be provided with the active wire folder 3 and shell fragment 4 that middle part is straight plane, two ends are curved, and be provided with earth connection terminal 2 at one side arm, be connected with insulating bar 8 by the active joint be made up of top connection 5, lower contact 6 and fastening bolt 7.Top connection 5 and lower contact 6 one end are cylindrical, the other end is semi-cylindrical, semi-cylindrical side plane is the male and fomale(M&F) of rule, and on semicolumn, be provided with the adjustment slotted eye be fixedly connected with by fastening bolt 7, cylindrical end and " U " type crotch 1 one side arm end connecting hole of top connection 5 are fixedly linked, and the cylindrical end of lower contact 6 is fixedly connected with insulating bar 8 upper end.Also can arrange to connect in insulating bar 8 lower end and extend screw connection hole 9 in insulating bar 11, be connected with insulating bar 8 by the external screw thread 10 being arranged on the upper end extending insulating bar 11.When implementing the utility model, operating personnel can adjust angle between " U " type crotch 1 and insulating bar 8 in the position residing for self and wire, when carrying out earth connection to the circular bare wire of transformer station or field, the earth connection rod regulating angle only need firmly be hooked on bare wire by operating personnel, under the effect of shell fragment 4, circular bare wire is tightly clamped by the circular arc of arcuation elbow and " U " type crotch 1 top that active wire presss from both sides 3 tops, when in transformer station, aluminium row wire needs earth connection to keep in repair, " U " type crotch 1 on insulating bar 8 only need be regulated by active joint by operating personnel, make aluminium arrange wire and press from both sides 3 mid-plane location in active wire, aluminium is arranged wire and is tightly clamped by active wire folder 3 under the effect of shell fragment 4, both ensure that the compact siro spinning technology of ground wire and circular bare wire, also guarantee no matter the whether tensioned wind large even again of wire also can not make the hook of grounding wire device come off on wire simultaneously, thus guarantee the job safety of maintainer.The utility model is not only rational in infrastructure, easy to operate, widely applicable, safe and reliable, but also improves the operating efficiency of upkeep operation, has application value widely.
