Abstract

The utility model discloses a large-current wall bushing link end fitting which mainly comprises an end fitting wire clip body fixedly connected with a tubular bus, wherein the end fitting wire clip body is connected with a connection contact plate by a current-carrying conductor; the connection contact plate is fixedly connected on a wall bushing by a copper compound sheet with silver-plated surfaces; one end of the current-carrying conductor is welded on the end fitting wire clip body, and the other end of the current-carrying conductor is welded on the connection contact plate and is in transition connection with the wall bushing by the copper compound sheet with silver-plate surfaces; the current-carrying conductor comprises at least eight conductors which are uniformly distributed on the end fitting wire clip body up and down in a U shape, can carry large current and have same length; and the copper compound sheet with silver-plated surfaces comprises copper compound sheets with silver-plated surfaces. The large-current wall bushing link end fitting has characteristics of good corona shielding effect, reliable current carrying performance, good telescopic performance, capabilities of preventing equipment damage phenomenon caused due to uneven and excessive stress and the like.

Description

Big electric current wall bushing connects gold utensil
Technical field
The utility model relates to the jockey that a kind of wall bushing links to each other with tubular bus, particularly a kind of supporting big electric current wall bushing of power transformation DC ice melting engineering project that is applied in connects gold utensil, belongs to electric substation fitting and makes the field.
Background technology
Powerline ice-covering phenomenon under the winter freezing sleety weather is a kind of natural calamity of serious threat power system safety and stability operation.Therefore particular study group or research institution have been set up in many countries and regions, carry out the exploration and the test of " removing ice of power transmission line technology ", and have obtained certain experience.The thermal ice-melting method is utilized various technology exactly, to increase current density or the alternate manner in the transmission line, makes lead self produce abundant heat, comes off to avoid covering of ice and snow to amass or existing icing is melted.Wherein study more direct current de-icing technology, the high-capacity direct current electric current that needs to be installed in indoor DC de-icing device output directly inserts outdoor tubular bus by wall bushing, and can satisfy the requirement that tubular bus is subjected to displacement because of expanding with heat and contract with cold, still there is not available connection gold utensil at present.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that prior art exists, and can be connected gold utensil with the supporting big electric current wall bushing of 500kV power transformation DC ice melting engineering project and provide a kind of.
The purpose of this utility model is finished by following technical solution, it mainly comprises a gold utensil wire clip body of fixedlying connected with tubular bus, described gold utensil wire clip body by current carrying conductor be connected contact plate and link to each other, this connection contact plate is fixedly connected on the wall bushing by electroplate copper composite sheet.
Described current carrying conductor one end is welded on the described gold utensil wire clip body, and the other end is welded on the described connection contact plate, and is connected with described wall bushing transition by described electroplate copper composite sheet.
Described current carrying conductor by at least eight be " U " font be evenly distributed on up and down on the gold utensil wire clip body, can bearing great current and the identical lead of current carrying conductor length form; Described electroplate copper composite sheet is made up of the copper composite sheet of electroplate.
Advantage of the present utility model has: the one, and have and shield corona effects preferably, gold utensil overall appearance structure is a curve form, and is smooth smooth, do not have obviously projection, effectively eliminated electric discharge phenomena own, guarantees power plant safety, stable operation; The 2nd, the current-carrying dependable performance, it adopts at least eight current carrying conductors arranged evenly symmetrically and evenly up and down, and current carrying conductor length is identical, and electric current is evenly passed through, and ampacity is big, also can not make current-carrying safer, stable because of the local pyrexia of current-carrying inequality; The 3rd, telescopicing performance is good, and because of tubular bus expands with heat and contract with cold, gold utensil needs freely to stretch.It is arranged evenly symmetrically and evenly up and down that this gold utensil lead is, and stressed even, retractility is good, thereby prevents equipment unbalance stress, the excessive generation that causes disrepair phenomenon.
