Description
Technical field
The present invention relates to electric power overhaul instrument, specially a kind of Hi-pot test lead windguard, mainly for detection of power transformation
High-tension apparatus in standing.
Background technology
In power equipment maintaining work, it is often necessary to carry out test detection to the high-tension apparatus in transformer station, it usually needs will
The test clip of instrument test lead ends is connected on high-tension apparatus, is then connected corresponding tester and is detected, belongs to straight
Tape splicing electro-detection operation.The problem of existing is, because high-tension apparatus position is often higher, the influence of wind-force be it is inevitable,
After test clip is connected with high-tension apparatus, due to the effect of wind-force, test lead is possible to the wind disorderly pendulum, contacts other equipment,
Due to being live testing operation, being normally carried out for test job is not only influenceed, and very big potential safety hazard be present.
The content of the invention
It is an object of the invention to provide a kind of Hi-pot test lead windguard, mainly for detection of the high pressure in transformer station
Equipment, it is the instrument test lead of live detection high-tension apparatus, safe high pressure can also be set in the case of even if there is wind
It is standby to carry out test jobs, the influence of wind-force is reduced as far as possible.
The present invention adopts the following technical scheme that realization：
A kind of Hi-pot test lead windguard, including bobbin winoler, the bobbin winoler include housing, end cap and core.
The end face of the housing is connected with end cap, and the side of the housing is provided with lead wire outlet, and the center of the housing is stretched out
Have around axle, the bottom surface inner wall edge of the housing is provided with positive stop lug boss.
The core includes substrate, and the circle centre position of the substrate is provided with around axis hole, in the front and back of the substrate
Center portion has each extended over wire connection cavity and spring cavity, and the side of the wire connection cavity becomes coiling face, and the edge of the wire connection cavity prolongs
Stretching has some and substrate-parallel coiling flap, and the side of the wire connection cavity forms fracture, if being provided with stem grafting in the wire connection cavity
Terminal, connecting test wire one end respectively on the binding post, the test lead is stretched out by fracture wound along coiling face after, survey
Try the wire other end to stretch out from the lead wire outlet of housing, the other end of the test lead is connected to test clip；The substrate
Dorsal edge is provided with position-limit mechanism, and the position-limit mechanism includes the left end post and right-hand member post positioned at substrate back edge, described
Connected between left end post and right-hand member post by flexible spacing curl, the middle part of the spacing curl is provided with spacing concave tooth；
The position-limit mechanism includes the spacing rotor being installed between left end post and right-hand member post, and the spacing rotor is carried on the back around substrate is fixedly arranged on
The limit shaft of face edge rotates, and the spacing rotor has drift angle and two base angles；Clockwork spring bullet is installed in the spring cavity
Spring.
The end cap inner central section is provided with some circle copper rings, and copper ring contacts with different binding posts respectively, each copper ring
Had point of contact to the extension of end cap outer central sections, the contact point is connected with connecting wire.
In use, when core 3 is in clockwork spring 311（Plane scroll spring）In the presence of when rotating in the counterclockwise direction,
Position-limit mechanism is with the counterclockwise rotates of core 3, as shown in fig. 7, the position-limit mechanism on the substrate 31 of core 3 is passing through shell every time
During positive stop lug boss 12 in body 1, the drift angle of spacing rotor 39 deflects to the right, against left end post 312, smoothly streaks positive stop lug boss
12, realize automatic contraction test lead 4；When core 3 is being rotated in a clockwise direction under artificially extracting test lead 4 out, such as Fig. 8
It is shown, clockwork spring 311 is compressed, the drift angle of spacing rotor 39 deflects to the left, when passing through the positive stop lug boss 12 in housing 1 every time,
Because spacing curl 315 has certain elasticity, appropriate elastic deformation can occur in the presence of manpower so that spacing turn
Positive stop lug boss 12 is streaked in the drift angle friction of son 39, and test lead 4 is constantly extracted out；Now, the base angle position of spacing rotor 39
In in spacing concave tooth 314, the drift angle of spacing rotor 39 prevents core 3 in the presence of clockwork spring 311 against positive stop lug boss 12
Rotate counterclockwise, as shown in figure 8, the length that fixed wire stretches out.When needing to close at test lead 4 in bobbin winoler, first
One small section of test lead is pulled out, then unclamps test lead, utilizes the contraction inertia of clockwork spring 311 so that spacing curl 315
The certain deformation of generation, the drift angle of spacing rotor 39 deflect to the right so that and spacing concave tooth 314 is produced at the base angle of spacing rotor 39, it
Afterwards under the recovery elastic force effect of clockwork spring 311, continue to close at test lead 4 in bobbin winoler, in the process, people also may be used
So that test lead to be filled in along lead wire outlet 11, the counterclockwise rotates of core 3 are aided in.
During work, two test clips 5 of the end of test lead 4 are clipped on high-tension apparatus to be tested respectively, from coiling
Extract test lead 4 in device out, stop after extracting appropriate length out, then access the connecting wire head at the end cap of bobbin winoler corresponding
Tester in.Due to the Action of Gravity Field of bobbin winoler, test lead is substantially at plumbness, is having the situation of wind in time
Under, test lead also will not disorderly be put with the wind, in the case of live testing operation, ensure being smoothed out for test job, be eliminated
Unnecessary potential safety hazard.
The present invention is reasonable in design, and instrument test lead is asked by wind-force interference when solving live detection high-tension apparatus
