Description

A quick assembly disassembly instrument for quadripartion conductor spacer

Technical Field

The utility model relates to a wire conductor spacer dismouting technical field specifically is a quick assembly disassembly tool for quadripartion wire conductor spacer.

Background

Because of rapid economic development in recent years in China, particularly the power consumption of five provinces in the south is increased rapidly, five direct current and eight alternating current 13 500 kilovolt western and east power transmission large channels are formed in the power grid in the south at present, each channel is 1000 kilometers or more, and the number of the four-split spacers exceeds 13 thousands. The air moist spacer bars in southern areas are easy to rust and are seriously vibrated and vibrated by breeze all the year round, so the spacer bars are seriously damaged. At present, the wire clamp rotary four-split damping spacer is adopted for 500kV and above lines governed by the ultra-high voltage transmission company of the power grid in south China to prevent the problem of conductor span.

The four-split damping spacer is a flexible or semi-rigid spacer capable of reducing breeze vibration or sub-span oscillation of split conductors. The 500kV transmission line in China adopts a four-split conductor structure. The spacer is a main hardware fitting in a split conductor structure, and the basic tasks of the spacer are as follows: prevent whiplash between wires, suppress breeze vibration and subspan oscillation. The most used are damped spacers, which have better damping properties than rigid spacers. The spacer includes a plurality of fixed clamps which are pivotable in a longitudinal direction of the conductor, i.e. in a front-to-back direction in a plane perpendicular to the plane of the paper, but are substantially fixed against rotation in a tensioned clamping position, and a polygonal clamp holder. For a split conductor, there is typically a spacer every few tens of meters to connect the sub-conductors together. The two ends of the sub-conductor in each sub-span are fixed by the spacers, the torsional rigidity is greatly higher than that of the single conductor with the same section, the sub-conductor is difficult to twist around the axis of the sub-conductor after eccentric icing is generated, the eccentric icing condition cannot be relieved, the eccentric icing forms fan-shaped, crescent-shaped and other uneven icing, and the aerodynamic load acting on the split conductor is naturally much larger than that of the single conductor. This is also the main reason why split conductors are more prone to waving than single conductors.

The replacement work of the 500kV transmission line four-split spacer is a main overhaul work project of the transmission live working. The transmission line consumes the vibration energy of the wire, generates damping action on the vibration of the wire, inhibits the oscillation of the sub-span and the breeze vibration, and is provided with a large number of four-split spacing rods.

The application contrast of current conductor spacer assembly and disassembly tools and this scheme to the four-bundle conductor spacer dismouting that needs the dismouting:

1) the existing conductor spacer disassembling tool parameter introduction:

screw pitch of the screw: the pitch, i.e., the lead, is the linear distance that the nut advances for each rotation of the screw, and the screw pitch p is 2 mm.

The number of turns N1 of the lead screw needs to be fastened when the spacer is disassembled and assembled every time;

measuring the fastening distance D to be 1.1cm each time; n-D/p-5.5.

However, the number of fastening turns N1 of a jaw at one position of the spacer during each disassembly and assembly is measured to be 6 turns; therefore, the number of turns N1 which need to be fastened for each time of dismounting the spacer lead screw is 4 multiplied by 6 multiplied by 24 turns ("4" stands for four-split conductor).

The disassembly and assembly of the spacer at each time needs fastening time: according to actual statistics, the fastening time T of one fastening circle is averaged to be 10s, and the fastening time T1 is equal to 24 multiplied by 10 to 240 s; the time t1 required for inserting the compression pin 126 is 4 × 10s, 40s ("4" is a quad conductor).

The spacer is disassembled and assembled each time when the lead screw needs to be loosened, the number of turns N2 needs to be rotated;

in the same way, when the screw rod is loosened, the through nail is inserted into the jaw, so that the number of turns N2 of the screw rod needs to be 5 when one jaw is loosened; the number of turns N2 for dismounting the spacer bar and loosening the lead screw is 4 multiplied by 5 multiplied by 20.

The time required for dismounting the spacer bar and loosening the screw rod every time: the release time T2 is 20 multiplied by 10 to 200 s; the time t2 required for pulling out the pin is 4 × 10s 40 s.

Time required for disassembling and assembling the spacer:

the time H for disassembling the spacer is T1+ T2+ T1+ T2 is 520 s.

2) Parameter introduction of the scheme:

power arm/resistance arm: l1 is equal to 35cm and L2 is equal to 7cm (when the base 5 is adjusted, L2 is affected to a certain extent, and the length of L1 is affected to a certain extent due to different holding positions); L1/L2 is equal to about 5 (L1/L2 is considered to be 5 here).

The labor-saving condition of the scheme is as follows: the lever definition indicates that F1 × L1 is F2 × L2(F1 is the force for crimping the spacer jaws, and F2 is the reaction force of the spacer jaws), that is, F1 is L2/L1 × F2; the data is entered, namely F1 is 1/5 × F2; it can be concluded that within the reasonable length of the working tool, the human body only has to overcome one fifth of the reaction force caused by the pinching of the spacer jaws. The average time T1 taken to press the spacer jaws once is 3 s.

Time required for disassembling and assembling the spacer: the disassembly and assembly of one spacer are carried out for 8 times; the time H required for disassembling the spacer is 8 XT 1+ T1+ T2 is 24+80 is 104 s.

3) The existing conductor spacer disassembling and assembling tool is compared with the scheme in terms of use time;

tb 104s < Ta 520 s; Tb/Ta 1/5 ═ 20%; therefore, the scheme can meet the expected requirement.

Having shown and described the basic principles and principal features of the invention and advantages thereof, it will be apparent to those skilled in the art that the invention is not limited to the details of the foregoing exemplary embodiments, but is capable of other specific forms without departing from the spirit or essential characteristics thereof; the present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein, and any reference signs in the claims are not intended to be construed as limiting the claim concerned.
