Abstract
The utility model discloses a plugging electric connection construction used in GIS, comprising a connection conductor, a guidance sleeve, a contact seat connected with external conductors, and shielding cover fixed on the contact seat, which is characterized in that the contact seat is in stepped shape and comprises a rear portion, a intermediate portion with sequentially decreased diameter and a front portion; the shielding cover is fixed on outer diameter of rear portion of stepped contact seat; a ring shaped interval is axially formed between the shielding cover and central portion of the stepped contact seat, a spiral spring contact is fixed on outer diameter of front part of stepped contact seat central portion. The connection conductor is a tubular conductor, which extends into the inner surface of the ring shaped interval and is elastically plugged with the spiral spring contact. The guidance sleeve is fixed on end portion of the contact seat for supporting the conductor. The utility model decreases amount of assembled parts of contact, thus simplifies assembling process of the parts, and lowers possibility of error occurrence in assembling process.
Description
Technical field
The utility model relates to a kind of electric connection structure, particularly a kind of electric connection structure that patches that is used for gas-insulated switchgear (GIS).
Background technology
Existing a kind of being used for adopted Mume flower contact assembling (Fig. 1) at the electric connection structure that patches of GIS, in its contact base, be equipped with surplus the parts 30 such as spring, fingertip, guide plate, radome, and the bonding conductor of adapted welding.The major defect of this electric connection structure is: complex structure, required amount of parts is many, according to the difference of equipment rated current only the quantity of fingertip do not wait from tens to tens; Assembly work is complicated, if the assembling of arbitrary link is bad, will cause entire equipment normally to use, simultaneously because amount of parts is many, and the manufacturing cost height.
Summary of the invention
The utility model provides a kind of novel electric connection structure that patches that can significantly reduce contact assembling amount of parts at the existing problem of background technology.
For reaching above purpose, the utility model takes following technical scheme to be achieved:
A kind of GIS of being used for patches electric connection structure, comprise bonding conductor, the contact base, the fairlead that are connected with external conductor and be fixed on radome on the contact base, it is characterized in that described contact base is one and comprises the stage casing that back segment, diameter reduce successively and the stairstepping contact base of leading portion; Described radome is isometrical to be fixed on the external diameter of this stairstepping contact base back segment; Form an annular space between the stage casing of this radome and stairstepping contact base is axial, be fixed with the helical spring contact on the anterior external diameter in described stairstepping contact base stage casing, described bonding conductor is a tubular shape conductor, and its medial surface and helical spring contact elasticity that stretches in the annular space is pegged graft.
In the such scheme, described fairlead is arranged on stairstepping contact base leading portion end, and this fairlead is connected with the medial surface resiliency supported of tubulose bonding conductor in stretching into annular space.Described fairlead is the double-deck resilient sleeve of a flange.Described tubulose bonding conductor is formed by the direct machine work of pipe profile, and the internal diameter of its two ends symmetry is greater than the internal diameter of central tube section bar.
Compare with background technology, the utility model has the advantages that:
1, significantly reduced the amount of parts of contact assembling, can be surplus original 30 have reduced to 5, thus simplify greatly zero the assembly work of parts, reduced the mistake that may occur in the assembling process.
2, bonding conductor can be improved to by original welding conductors (2 conductor tab, middle be excellent section bar) and pipe profile (adopting same material with former excellent section bar conductor) is directly carried out the two ends machine work form, simplified processing technology, reduced processing cost, because bonding conductor blank area diameter becomes big, can increase the through-current capability of conductor simultaneously.
3, owing to installed fairlead additional in stairstepping contact base leading portion end, played bonding conductor good supporting and positioning action, made bus length increase to 8m length by original 3m length, can significantly reduce the quantity that disc insulator and bonding conductor use, reduce the device fabrication cost.

Embodiment
Below in conjunction with drawings and Examples the utility model is described further.
Shown in Figure 3 as Fig. 2, a kind of GIS of being used for patches electric connection structure, adopts the assembling of stairstepping contact base and helical spring contact, the bonding conductor of adapted pipe profile processing.Concrete structure is: the helical spring contact is embedded on the anterior external diameter in stairstepping contact base 8 stage casings, and fix an isometrical radome 5 at stairstepping contact base 8 back segment external diameters, simultaneously on stairstepping contact base 8 leading portion ends, be fixed for supporting the fairlead 10 of tubulose bonding conductor 11, fairlead 10 can be made the double-deck resilient sleeve of flange, to strengthen the resiliency supported dynamics.Tubulose bonding conductor 11 is formed by the direct machine work of pipe profile, the internal diameter of its two ends symmetry is greater than the internal diameter (Fig. 3) of central tube section bar, the one end is pegged graft by annular gap between radome 5 and stairstepping contact base 8 stage casings and helical spring contact 9, and the other end can be done same grafting.Tubulose bonding conductor 11 utilizes the contact-making surface of its medial surface as water conservancy diversion.This structure current direction: tubulose bonding conductor 11
Helical spring contact 9
Stairstepping contact base 8
External conductor 7.
