Abstract

The utility model relates to a T-shaped tubular bus fitting provided with a drainage wire clamp for a 500kV alternating/direct current transformer substation, which not only has good electrical conductive performance, but can effectively avoid visible corona from producing when high current passes through. The fitting comprises a wire clamp body and a wire clamp cover plate, wherein, the wire clamp body is provided with a large circular arc radius groove, of which the size is consistent with that of a matched tubular bus; and the wire clamp cover plate is matched with the large circular arc radius groove. The fitting has the advantages that firstly, the electrical conductive performance is good, and visible corona can be avoided from producing when high current passes through; secondly, the fitting adopts special ZL102 aluminum alloy as raw material, to which trace elements such as strontium, silicon, manganese, magnesium, rare earth, and the like are added, is melted under a certain high temperature conditioner, and is formed by adopting a gravity casting process, and through solid melting, ageing heat treatment, and surface treatment such as polishing, shot peening, chemical passivation, and the like, high strength, high toughness, corrosion resistance, high temperature resistance of a product are achieved; thirdly, the energy-saving effect is obvious and is improved by 10 percent to 20 percent; and fourthly, the fitting has a novel, unique and simple structural design, is convenient to mount, and is suitable for the 500kV alternating/direct current transformer substation.

Description

The pipe bus T of 500kV AC and DC transformer station type band drainage wire clamp gold utensil

Technical field

The utility model relates to a kind of excellent conducting performance that both had, and the pipe bus T of the 500kV AC and DC transformer station type band drainage wire clamp gold utensil that visual corona produces in the time of effectively avoiding big electric current to pass through again belongs to the electric power equipment and makes the field.

Background technology

At present, the continuous increase of domestic electricity needs, the various places power load is increasingly sharpened, and conventional transformer station is because of reasons such as capacity, ampacity are little, and the pipe bus T of AC and DC transformer station type band drainage wire clamp gold utensil can not satisfy growing electricity needs.

The utility model content

Purpose of design: avoid the weak point in the background technology, design a kind of excellent conducting performance that both had, the pipe bus T of the 500kV AC and DC transformer station type band drainage wire clamp gold utensil that visual corona produces in the time of effectively avoiding big electric current to pass through again.

Design: in order to realize above-mentioned purpose of design.The design that the pipe bus T of 500kV AC and DC transformer station type band drainage wire clamp gold utensil is made up of wire clip body, wire clamp cover plate, bolt is a major technique feature of the present utility model.The purpose of doing like this is: 1, wire clip body is provided with a large circular arc radius groove, its size with supporting pipe bus consistent, wire casing inner surface fineness is consistent with pipe bus surface, guarantee excellent conducting performance, body peripheral edge adopts large radius arc to handle, effectively avoid big electric current by the time visual corona that produces.2, be provided with 4 in a side of wire clip body and draw connecting groove, draw connecting groove for 4 and form a square by the electrical distance size, each connecting groove is by the corresponding little arc groove of the size configure of drawing lead, clamping performance and electric contact performance that maintenance is good to lead, the reverse side at each connecting groove position, be arranged to arc and protrude the position, effectively improve the dizzy performance of this position intensity and discharge.

Technical scheme: the pipe bus T of 500kV AC and DC transformer station type band drainage wire clamp gold utensil, form by wire clip body, wire clamp cover plate, wire clip body is provided with a large circular arc radius groove, its size with supporting pipe bus consistent, the wire clamp cover plate matches with the large circular arc radius groove.

The utility model is compared with background technology, and the one, both had excellent conducting performance, visual corona produces in the time of effectively avoiding big electric current to pass through again; The 2nd, it is raw material that material adopts with special ZL102 aluminium alloy, add the fusion under certain hot conditions of trace elements such as strontium, silicon, manganese, magnesium and rare earth, adopt the gravity-assist pouring technological forming, through solid molten, timeliness heat treatment, the surface reaches high strength, high tenacity, corrosion-resistant, the resistance to elevated temperatures of product again through processing such as polishing, shot-peening and chemical passivations; The 3rd, energy-saving effect is remarkable, has improved 10～20%; The 4th, structural design novelty, uniqueness, simple, easy for installation are applicable in the 500kV AC and DC transformer station.

Embodiment

Embodiment 1-4.500kV AC and DC transformer station pipe bus T type band drainage wire clamp gold utensil is made up of wire clip body 1, wire clamp cover plate 2, and wire clip body 1 is provided with a large circular arc radius groove, its big or small with supporting pipe bus 4 consistent, wire clamp cover plate 2 matches with the large circular arc radius groove.

The wire casing inner surface fineness of described large circular arc radius groove is consistent with pipe bus surface, guarantee excellent conducting performance, according to big electric current (the resistance temperature rise principle during 6000～6400A) circulations, adopt suitable width and thickness, body peripheral edge adopts large radius arc to handle, effectively avoid big electric current by the time visual corona that produces.

Described wire clip body 1 one sides are provided with 4 and draw connecting groove 5, draw connecting groove for 4 and form a square by electrical distance, each connecting groove is by the corresponding little arc groove of the size configure of drawing lead, clamping performance and electric contact performance that maintenance is good to lead, the reverse side at each connecting groove position, be arranged to arc and protrude the position, effectively improve the dizzy performance of this position intensity and discharge, it is raw material that material adopts with special ZL102 aluminium alloy, add strontium, silicon, manganese, the fusion under certain hot conditions of trace element such as magnesium and rare earth, adopt the gravity-assist pouring technological forming, through solid molten, timeliness heat treatment, the surface is again through polishing, processing such as shot-peening and chemical passivation reaches the high strength of product, high tenacity, corrosion-resistant, resistance to elevated temperatures.The wire clamp cover plate adopts and the design of main body wire casing isostructure, when both are used by bolt, not only lead is produced enough clamping forces, more effectively satisfies resistance temperature rise performance and anticorona performance, and material adopts and the equal material of body.

This 500kV AC and DC pipe bus T of transformer station type band drainage wire clamp gold utensil, when system is steady, (6000～6400A) at first pass through supporting pipe bus to the big electric current of being introduced by the external world, with big current delivery to wire clip body 1 and wire clamp cover plate 2, the biggest electric current branches to 4 root leads, realizes with the shunting of four on root pipe bus function.

What need understand is: though the foregoing description is to the mentality of designing of the present utility model detailed text description of contrasting; but these text descriptions; just the simple text of the utility model mentality of designing is described; rather than to the restriction of the utility model mentality of designing; any combination, increase or modification that does not exceed the utility model mentality of designing all falls in the protection range of the present utility model.
