Abstract
The utility model relates to a three-phase wire interphase imbalance tool. The interphase imbalance tool is characterized by comprising a trapezoidal plate (1), two through holes (2) are formed in the middle of the upper bottom of the trapezoidal plate (1), the two ends of the lower bottom of the trapezoidal plate (1) are respectively provided with a through hole (2), a flange (3) is installed beside each through hole (2) of the two ends of the lower bottom and perpendicular to the trapezoidal plate (1), and a through hole is also formed in each flange (3). It is proved through trials that by the adoption of the tool, the winding phenomenon of three-phase wires is greatly avoided when the wires are unfolded, labor intensity of workers is greatly reduced, power outage time is greatly shortened, and labor efficiency is improved; wire unfolding and paying-off in construction are convenient after the tool is adopted, power outage time shortening is facilitated, and working efficiency of construction and new circuit erection is improved.
Description
Technical field
The utility model relates to the alternate uneven instrument of a kind of three-phase conducting wire.
Background technology
In recent years, in power construction, new stringing road, three-phase conducting wire unfolds (one leads three) simultaneously, has realized the unsettled unwrapping wire of circuit, has successfully solved spreading conducting wire process, in construction, realizes three wires and unfolds simultaneously and increased substantially operating efficiency.But in practice of construction, while often there is spreading conducting wire, three-phase conducting wire unbalance stress etc. makes towing plate imbalance, cause three-phase conducting wire to be wound around, now must step on bar operation by workmen, manually the wire being wound around is flattened, continuing unfolding work, this has not only increased difficulty of construction, has also wasted human cost, also the effort of raising the efficiency is had a greatly reduced quality simultaneously.
For example certain city electric power system in decades 10 kilovolt constructions are continued to use always and are manually dragged spreading conducting wire, make three-phase unbalance stress, cause construction of line insulator to be drawn by wire askew, when three-phase conducting wire unfolds simultaneously, energy imbalance is very outstanding, needs workmen to step on bar adjustment.This maintenance crew of power supply administration of city occurs that when to 12 line constructions the alternate uneven number of times of unfolding conductor reaches 364 times, cause three-phase conducting wire to be wound around up to 99.7%, and spended time goes upset to account for 42.3% of the construction used time, the uneven number of times of unwrapping wire wherein causing because of " towing plate disequilibrium extreme difference " reaches 262 times, having accounted for 72%, is the subject matter that circuit exhibition payingoff construction exists.
Utility model content
The purpose of this utility model is to provide the alternate uneven instrument of a kind of three-phase conducting wire, and the three-phase conducting wire balance can ensure spreading conducting wire after use time is drawn askew phenomenon thereby reduce insulator.
The alternate uneven instrument of a kind of three-phase conducting wire, its special feature is: comprise a trapezoidal plate, in the middle of the upper base of this trapezoidal plate, have two through holes, have a through hole at the two ends of going to the bottom of this trapezoidal plate, and the each through hole side at these two ends of going to the bottom is all provided with the rib vertical with this trapezoidal plate, also has through hole on this rib.
Wherein two through holes in the middle of the upper base of trapezoidal plate distribute along the short transverse of this trapezoidal plate, and the spacing of these two through holes is 120mm.
Wherein on described trapezoidal plate, have a dovetail groove, and the shape of described trapezoidal plate and this dovetail groove is isosceles trapezoid.
Wherein on rib, be provided with arc groove.
Through probationary certificate, adopt after instrument of the present utility model, the wrapping phenomena of three-phase conducting wire while having avoided greatly spreading conducting wire, greatly reduce employee's labour intensity, shorten interruption duration, improved efficiency, adopted after instrument of the present utility model as construction unfolding line provides convenience, be conducive to shorten interruption duration, improve the operating efficiency on construction, new stringing road.
Brief description of the drawings
Accompanying drawing 1 is structural representation of the present utility model;
Accompanying drawing 2 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, 2, the utility model is the alternate uneven instrument of a kind of three-phase conducting wire, comprises a trapezoidal plate 1, specifically can adopt iron plate, steel plate or aluminium alloy plate.In the middle of the upper base of this trapezoidal plate 1, have two through holes 2, have a through hole 2 at the two ends of going to the bottom of this trapezoidal plate 1, and the other rib vertical with this trapezoidal plate 13 that be all provided with of each through hole 2 at these two ends of going to the bottom, can be close to wire easily fixing thereby the one side contacting with wire on rib 3 is provided with arc groove, on this rib 3, also have through hole 2.
Wherein two through holes 2 in the middle of the upper base of trapezoidal plate 1 distribute along the short transverse of this trapezoidal plate 1, and the spacing of these two through holes 2 is 120mm.Wherein on described trapezoidal plate 1, have a dovetail groove, and the shape of described trapezoidal plate 1 and this dovetail groove is isosceles trapezoid, thereby can in ensureing trapezoidal plate 1 structural strength, reduces its weight as far as possible.
Using method of the present utility model is:
When use by two wires of arranged on left and right sides respectively purposes binding wire be temporarily fixed at other through hole 2 places of two of 1 belows of trapezoidal plate rib 3, it is temporary fixed that a middle wire coordinates binding wire to carry out by two through holes 2 in the middle of trapezoidal plate 1 top, like this in the time of spreading conducting wire, the stressed equalization of three-phase conducting wire makes towing plate remain balance, avoid the winding of three-phase conducting wire, after completing, binding wire and trapezoidal plate 1 have all been taken off from wire.
