Description
Technical field
The present invention relates to current transformer experimental technique field.
Background technology
With economic development and the increase of power consumption, the experiment work of facility, equipment in power supply system is increasingly
It is heavy.In substation equipment maintenance and repair, current transformer test number (TN) at most, almost 250 times in teams and groups 1 year.Therefore, carry
High current transformer test efficiency is significant.
Found through analysis, Wiring step is tested in current transformer test operation and is taken at most, average used time 10-20 points
Clock.Because current transformer height is higher, the conventional ladder being equipped with is reached, and operating personnel cannot directly wiring, it is necessary to by
Peg.Peg is main to be constituted by insulating bar and in the hook that its one end is set.There is problems with prior art peg：
1st, need to splice with other extension bar when insulating bar is lengthened, fixed using threaded connection more, be aligned between two bars, spun
Time-consuming, accounts for more than the 60% of peg patching operations time；
2nd, hook-shaped is unreasonable, and hook is in semicircular arc, and by sheet steel are made, the position linked up with during peg patching operations
And angle of inclination difference can make contact resistance that very big difference occurs, the accuracy of influence current transformer experiment is, it is necessary to repeatedly adjust
Whole hook angle of inclination is so that contact resistance is smaller, it is impossible to more than the maximum of regulation, influences wiring efficiency；
3rd, hook drop-proof is using the soft copper line traffic control for setting thereon, but easily occurs annealed copper wire when dislodging hook and hook spiral shell
The situation of bolt, is 20% through testting the occurrence probability of the phenomenon, hinders hook to win, and influences efficiency.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of current transformer test connection action bars, simple structure, behaviour
Facilitate, current transformer test connection efficiency can be effectively improved, it is ensured that wiring quality, effectively reduce personnel labor intensity.
In order to solve the above technical problems, the technical solution used in the present invention is：A kind of current transformer test connection behaviour
Make bar, including extension type insulating bar and the hook being fixed at the top of it, the hook includes column and is fixed on the column
The downward right angle hook of upper inlet, the column and right angle hook are by section by circular steel are made.
The hook also concave frame including opening upwards, the concave frame is fixed on the column upper end, the right angle
The top of hook, the concave frame by by section by circular steel are made.
The steel are manganese alloy steel.
A diameter of 1-10mm of the steel.
The extension type insulating bar include socket can axially opposed slip inner and outer tubes, said inner tube bottom
Rotational lock mechanism is fixed with, said inner tube can be fixedly connected with outer tube by the rotational lock mechanism；The hook
It is fixed on the top of said inner tube.
Escapement is additionally provided between said inner tube and outer tube, for preventing inner tube from deviating from from outer tube.
It is using the beneficial effect produced by above-mentioned technical proposal：
1st, the present invention can keep the stabilization of hook by the shape of rational design hook.
2nd, hook uses circular steel, and how deflection can keep good contact all the time no matter to link up with angle.
3rd, the problem aligned when telescopic action bars is docked in the absence of two poles, it is easy to operate, reduce threading operation
Time.
Using current transformer test connection action bars of the present invention, individual event setting up time can be shorten within 5 minutes,
Operating efficiency is substantially increased, experimental accuracy is improve, contingency occurrence probability is reduced.
Brief description of the drawings
Fig. 1 is the schematic diagram of an embodiment of the present invention.
Wherein, 1, insulating bar；2nd, column；3rd, right angle hook；4th, concave frame；11st, inner tube；12nd, outer tube；13rd, ring is confined.
Specific embodiment
The invention will be further described with reference to the accompanying drawings and detailed description.
The present invention provides a kind of current transformer test connection action bars, sees Fig. 1, including extension type insulating bar 1 and solid
Hook at the top of it, hook includes column 2 and is fixed on the downward right angle hook 3 of the upper inlet of column 2, column 2 and right angle hook 3
By section by circular steel are made.Right angle hook 3, entrance is small, does not fall out.
The hook also concave frame 4 including opening upwards, concave frame 4 is fixed on the upper end of column 2, the top of right angle hook 3, spill
Frame 4 by by section by circular steel are made.Concave frame 4 conveniently carries out eminence operation.
The present invention can keep the stabilization of hook by the shape of rational design hook.Hook uses circular steel, nothing
By hook angle, how deflection can keep good contact all the time.
Steel are manganese alloy steel.
A diameter of 1-10mm of steel.
Extension type insulating bar 1 include socket can axially opposed slip inner tube 11 and outer tube 12, the bottom of inner tube 11
Rotational lock mechanism is fixed with, inner tube 11 can be fixedly connected with outer tube 12 by rotational lock mechanism；In hook is fixed on
The top of pipe 11.
Rotational lock mechanism is voluntarily selected according to prior art, and the present invention is fastened preferably by spring catch rotation lock.
Telescopic action bars is fitted together using bar with rod set, long by stretch mode change bar, when reaching correct position
Fixation is blocked by spring catch, the problem aligned when being docked in the absence of two poles is easy to operate, is fixed by spring catch, reduced
The time of threading operation.
Escapement is additionally provided between inner tube 11 and outer tube 12, for preventing inner tube 11 from deviating from from outer tube 12.For example,
It installs confinement ring 13 additional with the interface of inner tube 11 on outer tube 12, and tightening up 12 mouthfuls of outer tube prevents inner tube 11 from coming off from outer tube 12
Come.
The embodiment of the present invention is tested under the conditions of 4 grades of strong wind wind-force, and the test wire number of times that comes off is 0.Different wiring personnel hang
Between contact resistance is 70-74 micro-ohms after bar wiring, much smaller than the regulation maximum of 150 micro-ohms, sprung mass is stable.
Using current transformer test connection action bars of the present invention, 3 points of individual event setting up time average out to 35 seconds is greatly improved
Operating efficiency.
The present invention is described in detail above, application specific case is carried out to embodiments of the present invention in the present invention
Illustrate, the explanation of above example is only intended to help and understands the present invention, it is noted that for the technology people of the art
