The utility model relates to distribution transformer maintenance earthing device, is specially a kind of 10kV drop switch ground connection connecting rod.The technical problem that when having solved current distribution transformer and ground loop not being installed being caused upkeep operation, earth connection cannot articulate.A 10kV drop switch ground connection connecting rod, comprises a contact plate that is L-type, vertically has two connecting holes on the horizontal segment of contact plate, the corner of contact plate be fixed with one with contact plate horizontal segment and vertical section parallel hitching axis all; Contact plate is stretched out at the two ends of described hitching axis; The front end of contact plate horizontal segment is fixed with an operation pipe; Described operation tubular axis line is parallel with hitching axis axis.In distribution transforming maintenance, use this device, simple, convenient, be easy to carry, cheap, can meet and become the problem that in platform work, earth connection cannot articulate.

Description

10kV drop switch ground connection connecting rod
Technical field
The utility model relates to distribution transformer maintenance earthing device, is specially a kind of 10kV drop switch ground connection connecting rod.
Background technology
In changing or repair distribution transformer (particularly 10KV) work, after pulling open drop switch, need articulate at high-side lead place one group of earth connection, but in actual job site, ground loop is not installed in most of distribution transforming, in other part hanging earthing conductors existence of high-voltage connection, articulating circuit is the problem that insulated conductor cannot articulate, or cannot hang firmly problem in lightning arrester earth connection existence around, so, staff works and just cannot guarantee personal safety under the distribution transformer that ground loop is not installed, once the earth connection that occurs to install after the fault of drop switch insulation breakdown can not guarantee personal security, very easily there is accident of human electric shock.Therefore need a kind of device that can be applicable to not have to install the ring distribution transformer upkeep operation connecing.
Summary of the invention
The technical problem that when the utility model is not installed ground loop and caused upkeep operation for solving current distribution transformer, earth connection cannot articulate, provides a kind of 10kV drop switch ground connection connecting rod.
The utility model is to adopt following technical scheme to realize: a kind of 10kV drop switch ground connection connecting rod, comprise a contact plate that is L-type, on the horizontal segment of contact plate, vertically have two connecting holes, the corner of contact plate be fixed with one with contact plate horizontal segment and vertical section parallel hitching axis all; Contact plate is stretched out at the two ends of described hitching axis; The front end of contact plate horizontal segment is fixed with an operation pipe; Described operation tubular axis line is parallel with hitching axis axis.
Contact plate be responsible for drop switch under contact, hitching axis is responsible for earth connection to be suspended from drop switch undersetting draw-in groove, rises and supports turning effort, connecting hole is responsible for being connected with earth connection line nose, the responsible brake pull-rod of operation pipe (hole) operates.
When the utility model is used, 10kV earth connection is removed after shorting bar, 3 front end copper cash noses of earth connection are connected to connecting hole, then according to earth connection erection sequence, first connect earth terminal, then by 10kV insulating rod (brake pull-rod) " on " prefix cross bar penetrates from operation pipe (hole), hitching axis is put into drop switch undersetting draw-in groove, contact plate, under earth connection Action of Gravity Field, with contact close contact under drop switch, reaches ground connection object.
The beneficial effects of the utility model: in distribution transforming maintenance, use this device, simple, convenient, be easy to carry, cheap, can meet and become the problem that in platform work, earth connection cannot articulate.
The utility model can be used for various drop switch and articulates earth connection and support the use.
The utility model belongs to dismountable device, and Yi Ge power supply station configuration five covers just can meet daily required, have reduced production cost.

1-contact plate, 2-connecting hole, 3-hitching axis, 4-operates pipe.
Embodiment
A kind of 10kV drop switch ground connection connecting rod, comprise a contact plate 1 that is L-type, on the horizontal segment of contact plate 1, vertically have two connecting holes 2, the corner of contact plate 1 (be horizontal segment and vertical section junction inner side) be fixed with one with contact plate 1 horizontal segment and vertical section parallel hitching axis 3 all; Contact plate 1 is stretched out at the two ends of described hitching axis 3; The front end of contact plate 1 horizontal segment is fixed with an operation pipe 4; It is parallel with hitching axis 3 axis that 4 axis are managed in described operation.
On the front and back end line of centres that is centered close to contact plate 1 horizontal segment part of described two connecting holes 2.
The aperture of connecting hole 2 is 10.2mm; Operation pipe 4 internal diameters are 13.6mm; Hitching axis 3 diameters are 6.8mm.
The aperture of connecting hole 2 is conducive to the installation of earth connection, the internal diameter of operation pipe 4 can match with brake pull-rod, hitching axis 3 matches with the groove on contact base under falling type switch, the two ends of hitching axis 3 can be placed in the groove of base, make whole device can with lower contact close contact, guarantee earthing effect.
Fig. 1, Fig. 3 all can find out, contact plate 1 is L-type, and horizontal section length is generally greater than vertical section, and hitching axis 3 and operation pipe 4 parallel; Connecting hole 2 is positioned on the line of centres of contact plate 1 horizontal segment part front and back end.
