Abstract
The invention discloses a middle phase fixing piece of a horizontal conductor. A pin is inserted into left and right hanging plates of a supporting seat; a conductor spring is hung on the pin; a conductor which is sleeved in an opening rubber sleeve is clamped on the conductor spring; two fixed rubber sleeves are embedded in a lower cylinder of the supporting seat; and a porcelain rod penetrates into the two fixed rubber sleeves and penetrates into the supporting seat through a clamping spring to fix the supporting seat. By adoption of the middle phase fixing piece of the horizontal conductor, the conductor is flexibly connected with the porcelain rod, the stress of the conductor on the porcelain rod can be reduced, wire breakage is effectively prevented, and the middle phase fixing pieceof the horizontal conductor has the characteristics of simple structure and good safety.
Description
Technical field
The present invention relates to dead joint member, especially in the horizontal wire of electric power transmission line being the flexible attachment that lead and porcelain rod are connected to a fixed mutually.
Background technology
Current, in the 10kV transmission line, lead is fixed on the porcelain rod with aluminum steel after being parcel layer of aluminum band.In implementation process, labour intensity is big, has more hazards, simultaneously, easily lead is caused damage.In application process, because lead fixed is on the porcelain rod of hard, under the less external force effect of strength such as wind, lead and porcelain rod contact position are easily because of the tired thigh or break of break; Under the bigger external force effect of strength, cause accidents such as the porcelain rod that fractures, damage electric pole easily; Be subjected under the external force effect at electric pole, break lead easily, the porcelain rod that fractures, in addition get an electric shock, accident such as fire.
Summary of the invention
The purpose of this invention is to provide in a kind of horizontal wire with the flexible way connection and fix part.
The object of the present invention is achieved like this: fix part in a kind of horizontal wire, the supporting base structure is: the both sides of cylinder extend upward respectively and form left and right link plate, and pin interts on two hanging holes of this left and right link plate; The lead spring structure is: the two ends of flat spin spring vertically extend upward respectively, and helical disk coiled one vertical spring, upwards turn to link at last; The lead spring is suspended on the pin by two links on it; Be nested in the flat spin spring of lead spring as the opening gum cover on the fixing cord; The cylinder of supporting base is nested with as porcelain rod and inserts fixing two fixing gum covers, two fixedly gum cover be the open type gum cover, and two fixedly gum cover lay respectively at the above and below of four perforation on the cylinder of supporting base; Being shaped as by two straight sections and the U font that segmental arc is formed of the jump ring of the porcelain rod being fixed as the perforation on the insertion supporting base.
Be provided with the elasticity card article that is used as with the mating reaction of porcelain rod upper groove on two straight sections of above-mentioned jump ring.
Compare with existing being rigidly connected, the present invention has following characteristics and advantage:
1, can reduce the labour intensity of shop floor worker in the lead process is installed, reduction work danger.
2, lead is connected with the porcelain rod, and changes current rigid connection, lead and porcelain rod can move within the specific limits, reduce lead at the stress that porcelain rod place produces, the generation of the event that prevents from breaking.
3, move when electric pole is subjected to external force, the movement of porcelain rod and lead can reduce the risk that conductor cord disconnection, porcelain rod fracture; Or the reduction lead is subjected to big strength, the risk of fracture porcelain rod, electric pole.
4, be convenient to the application that the distribution line wire fracture is breaker device, prevent down that events such as rod disconnection cause the generation of accidents such as electric shock, fire.
The present invention is applied to the middle phase of 10KV and following distribution network cathetus bar especially.

Embodiment
Fixedly gum cover, pin, lead spring, (lead) opening gum cover etc. are formed by (porcelain rod) jump ring, supporting base, (supporting base) in the present invention.Pin is made up of pin, plain cushion and split pin.
Fig. 1 illustrates, and fixes part in this horizontal wire, and supporting base 5 structures are: the both sides of cylinder extend upward respectively and form left and right link plate, and pin 8 interts on two hanging hole 5b of this left and right link plate; Lead spring 7 structures are: the two ends of flat spin spring (as the 8-9 circle is arranged among Fig. 1) vertically extend upward respectively, and 3 circles are arranged among helical disk coiled one vertical spring 7b(Fig. 1), upwards turn to link 7a at last; Lead spring 7 is suspended on the pin 8 by two links on it; Be nested in the flat spin spring of lead spring 7 as the opening gum cover 6 on the fixing cord 1; The cylinder of supporting base 5 is nested with as porcelain rod 3 and inserts fixing two fixedly gum cover 2a, 2b, two fixedly gum cover be the open type gum cover, and two fixedly gum cover 2a, 2b lay respectively at the above and below of four perforation 5a on the cylinder of supporting base 5; Being shaped as by two straight sections and the U font (Fig. 5, Fig. 6) that segmental arc is formed of the jump ring of porcelain rod 3 being fixed as the perforation 5a on the insertion supporting base 54.
Referring to Fig. 2, Fig. 3, Fig. 4, four perforation are arranged on the bottom cylinder of supporting base.Referring to Fig. 7, Fig. 8, Fig. 9, two perforation from Fig. 2 of two straight sections of U-shaped jump ring are inserted, and pass (referring to Fig. 4) again from two perforation at cylinder rear portion, and namely former and later two Kong Weiyi group perforation on the supporting base form two groups of perforation altogether.
Be provided with on two straight sections of jump ring 4 as with the elasticity card article 4a(of porcelain rod 3 upper groove mating reactions referring to Fig. 9).(porcelain rod) jump ring, supporting base, pin, lead spring are made by the steel material with certain toughness, with carrying transmission line wire and the extraneous load that produces.
Supporting base fixedly gum cover is made by having certain flexible material, supporting base can be fixed on the porcelain rod; The lead gum cover is made by having certain flexible material, can absorb the vibrations of lead top, and lead is connected with the lead spring.
Using method:
