Description
Technical field
The utility model relates to a kind of anchor clamps, is specifically related to a kind of 500 KV lead sags adjustment auxiliary clamp.
Background technology
After voltage reached 500 kilovolts, lead was very serious to the corona phenomenon of air, especially big greasy weather, violent corona even can cause discharge accident.In order to reduce corona, must strengthen the conductor equivalent diameter, the Electric Field Distribution around the homogeneous conductor.But if with very large diameter solid conductor, not only weight is big, and because skin effect, lead is middle can not to be effectively utilized.Thereby produced and split into many way to a lead; The diameter of wire that so just has been equivalent to overstriking; Compare with solid conductor, bundle conductor can make that the inductance of power transmission line reduces, electric capacity increases, and its wave impedance to alternating current is reduced; Can contain the generation of corona well, improve the ability to transmit electricity of circuit.500 kilovolts of bundle conductors generally are that every phase conductor is formed with 4 less leads in cross section; At a distance of 0.5 meter, during Construction of Tension Stringing, must adjust to 4 root lead sags the same between intraphase conductor; Remain on the par line, could guarantee the mounting process and the security of operation of follow-up conductor spacer.Now in 500 KV inlet wires constructions, especially on the hills, the mountain area, when Construction of Tension Stringing is carried out in the area, high mountain, the sub-bank of the ubiquity bundle conductor adjustment situation of difficult of hanging down.End lead during Construction of Tension Stringing hangs up properly, and carries out the degree of tightness adjustment at the other end with strand mill or Lever Blocks, begins from distal-most end, and one grade of one grade of ground is to the leveling of stringing end.But; Owing to receive the frictional force of strain section length, landform, the iron tower discrepancy in elevation, releasing pulley, the influence of wire density, this several kinds of phenomenons often appear in sub-conductor: (1) this empty low and next outage, and (2) stringing end sag high (low) goes out a lot; Far-end sag still low (height); (3) the unexpected play of sub-conductor, the good sub-bank that causes adjusted the changing of haveing hair hang down have to be readjusted.Above-mentioned phenomenon causes the sag observed efficiency in the middle of the stringing low, and line transfer is slow, and construction is wasted time and energy.
Summary of the invention
The utility model is big, the problem that wastes time and energy of lead sag adjustment difficulty during to above-mentioned stringing, and a kind of lead sag adjustment auxiliary clamp is provided, and makes that the adjustment of lead sag is simple, has improved efficiency of construction greatly.
For realizing above-mentioned purpose, the technical scheme that the utility model is taked is:
A kind of lead sag adjustment auxiliary clamp; Comprise the jig I and with the supporting jig II of jig I, said jig I and jig II are fastening with the nut that is arranged on bolt upper end through bolt, jig I one end is drilled with screwed hole; The other end has U-lag, and jig I downside is provided with arc groove; Said jig II two ends all have U-lag, and jig II upper side is provided with and the corresponding arc groove of jig I downside arc groove, and said bolt lower end is installed in the U-lag of jig II through pin.
Be provided with four arc grooves on said jig I and the jig II.
Said nut is a wing nut.
The utility model has two jigs, and jig is provided with four arc grooves, is used for fixing lead, and two jigs are fastening through bolt, nut, and the utility model is simple in structure, and is easy to operate, improved efficiency of construction, improved the stringing qualification rate.
Description of drawings
Fig. 1 the utility model structural representation.
Fig. 2 the utility model structure jig I structural representation.
Fig. 3 the utility model structure jig II structural representation.
Embodiment
Like Fig. 1, the utility model structural representation, a kind of lead sag adjustment auxiliary clamp; Comprise jig I 2 and with the supporting jig II 3 of jig I 2, jig I 2 is fastening, as shown in Figure 2 with the wing nut 4 that is arranged on bolt 1 upper end through bolt 1 with jig II 3; The utility model jig I structural representation, jig I 2 one ends are drilled with screwed hole 8, and the other end has U-lag 9; Jig I 2 downsides are provided with arc groove 6, and are as shown in Figure 3, the utility model jig II structural representation; Jig II 3 two ends all have U-lag 10; Jig II 3 upper sides are provided with and jig I 2 downside arc grooves 6 corresponding arc grooves 7, and bolt 1 lower end 5 is installed in the U-lag 10 of jig II 3 through pinning, and are provided with four arc grooves on jig I 2 and the jig II 3.
When Construction of Tension Stringing, arrange to install the auxiliary clamp personnel of ascending a height in advance along the line according to the landform field condition and put in place, the high-altitude personnel ascended a height before stringing begins and carry out the preparation that auxiliary clamp is installed, and waiting rolls off the production line installs notice.When the sag of one grade of tension stringing section far-end or several grades of leads was tightened to the standard sag, the commanding promptly notified this location personnel to roll off the production line to begin to install auxiliary clamp.An end of jig I 2 links together with an end of jig II 3 through round bolt hole 8 and bolt 1, wing nut 4 before installing; The other end all is up and down a U type groove 6; Rotating bolt 1 is opened auxiliary clamp; The end that to open again after snapping on the lead rotates fastening bolt 1 altogether, tightens with wing nut 4.A bolt only need be installed in the high-altitude, fastening two wing nuts 4.Because what adopt is wing nut, so only with hand is fastening get final product, need not other specific purpose tools, after the dress auxiliary clamp tightens, the sub-bank of the lead of back is vertical just be fixed constant.Progressively be installed to one grade of the near-end of tension stringing section by that analogy, the work of this section stringing is promptly accomplished.
