Abstract
The utility model discloses a kind of temporary grounding link of 35kV or less portables with warning function.The utility model uses special chuck structure, and is provided with hanging ring structure, and the lower pile crown or parallel groove clamp of the connection disconnecting switch, drop out fuse that can be consolidated by collet avoid falseness and hang ground wire；The structure of the utility model middle link can be effectively increased the safe distance of operation, therefore, stop the power supply of upper level main line without drawing when the lower pile crown by disconnecting switch, drop out fuse carries out ground connection operation, and, ground wire is reliable across link stable connection, it even if installing ground wire has the action to rebound upwards in operation, can also be blocked by link, and remain safe distance.In addition, the device has the function of electrical verification alarm simultaneously, once there is the case where incoming call suddenly, operating personnel can be also reminded at the first time, traditional approach is avoided and there are problems that electrical verification cycle in time.
Description
Technical field
The utility model is related to technical field of electric power, specifically a kind of 35kV or less portables connecing temporarily with warning function
Ground link.
Background technology
Current distribution line (aerial) mostly uses insulated conductor, when line outage carries out ground connection operation, needs to pass through
Ground loop is grounded, and still, most of circuits are not equipped with enough ground loops, work as operation isolation in actual operation
When switch or drop out fuse carry out branched line or distribution low-voltage line maintenance, if under disconnecting switch or drop out fuse
Pile crown installing ground wire (upper pile crown electrification), due to only having 30cm or so between upper pile crown and lower pile crown, cannot meet《Electricity rule》
Requirement to safe distance, it is also necessary to which drawing stops upper level main line power supply and carries out ground wire installing again, thus expands power failure model
It encloses, increases a large amount of grid switching operation work, while also increasing security risk.If using parallel groove clamp in insulated conductor collet
Junction is grounded, and since the collet of the ground wire of each producer production can not be reliably connected with parallel groove clamp, ground wire can only be made to lean on
Nearly parallel groove clamp is actually to form falseness to hang in this way, there is very serious security risk, but in real work, work
Make personnel to scheme conveniently, to will also tend in this manner.Also, there is also another safety to ask for above two mode of operation
Topic, staff have carried out electrical verification operation before ground connection, have then hung ground wire again, during which when at least 3 minutes intervals of needs
Between, and during this, in case of scheduling error, or the case where generation anti-power transmission, then it can lead to electrical ground, may cause
Serious safety accident.
Utility model content
The technical problems to be solved in the utility model is：It is proposed a kind of 35kV or less portables connecing temporarily with warning function
Ground link, its convenient progress temporary grounding operation on the lower pile crown and parallel groove clamp of disconnecting switch or drop out fuse, and
Securely and reliably, with overcome the deficiencies in the prior art.
The utility model is realized in this way：Temporary grounding link of 35kV or less the portables with warning function, including bar
Body is equipped with collet at the top of the body of rod, and the composition of collet includes lead screw and Contraband shape frame, and the top of lead screw passes through the bottom of Contraband shape frame
Portion, and lower fixture block is connected at the top of lead screw, lower fixture block is in Contraband shape frame, and is equipped with guide rail in the inside of Contraband shape frame, under
Fixture block is equipped with corresponding guide groove, is to be flexibly connected to be threadedly coupled between lead screw and Contraband shape frame, between lead screw and lower fixture block；
Link is connected on the outside of Contraband shape frame, link is connected through bar and is connect with Contraband shape frame, and the ring part of link is made to be in Contraband shape
Below frame, link is well contacted and is connected with Contraband shape frame；Induction electroscopic device is equipped on Contraband shape frame.
The connecting rod of the link is integrated with ring body, and vertical total length is 20-30cm.
The ring body of the link is square frame-shaped.
The utility model has the advantages that：The utility model uses special chuck structure, and provided with extension
Ring structure, the lower pile crown or parallel groove clamp of the connection disconnecting switch, drop out fuse that can be consolidated by collet, avoids falseness
Hang ground wire；The structure of the utility model middle link can be effectively increased the safe distance of operation, therefore, by keeping apart
It closes, the lower pile crown of drop out fuse is carried out without the power supply for stopping upper level main line is drawn when ground connection operates, moreover, ground wire is being worn
It crosses that link stable connection is reliable, even if installing ground wire has the action to rebound upwards in operation, can also be blocked by link, and begin
Safe distance is kept eventually.In addition, the device has the function of electrical verification alarm simultaneously, once there is the case where incoming call suddenly, also can
Operating personnel are reminded at the first time, avoid traditional approach and there are problems that electrical verification cycle in time.The utility model is simple in structure, just
In carry, simple operation, and of low cost, using effect is good.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Specific implementation mode
The embodiments of the present invention 1：Temporary grounding link of 35kV or less the portables with warning function, including the body of rod 1,
It is equipped with collet 2 at the top of the body of rod 1, the composition of collet 2 includes that the top of lead screw 2-1 and Contraband shape frame 2-2, lead screw 2-1 pass through Contraband
The bottom of shape frame 2-2, and lower fixture block 2-3 is connected at the top of lead screw 2-1, lower fixture block 2-3 is in Contraband shape frame 2-2, and in Contraband
The inside of shape frame 2-2 is equipped with guide rail 2-4, and corresponding guide groove is equipped on lower fixture block 2-3, is between lead screw 2-1 and Contraband shape frame 2-2
It is threadedly coupled, is to be flexibly connected between lead screw 2-1 and lower fixture block 2-3；It is connected with link 3, link 3 on the outside of Contraband shape frame 2-2
It is connected through bar to connect with Contraband shape frame 2-2, the ring part of link 3 is made to be in below Contraband shape frame 2-2, link 3 and Contraband shape frame
2-2 well contact and conductings；Induction electroscopic device 4 is equipped on Contraband shape frame 2-2；The connecting rod of the link 3 is with ring body
