Abstract
The utility model discloses an electric connection device of a gas-insulated metal-enclosed switchgear and a button contact base thereof. The button contact base is used for the inserted connection with a plurality of annular grooves, which are continuously arranged on the sidewall of an inner hole of a conducting rod in a gapless manner and are used for the installation of spring button contacts. According to the utility model adopting the above structure, a plurality of multi-groove structures arranged at interval are improved to be individual wide groove structure by means of continuous processing on the basis of not varying the principal of original signal groove, thereby reducing the axial width of the button contact base of the original multi-groove structure and simplifying the multi-groove structure, and simultaneously lessening the difficulty of mechanically processing the annular grooves of the inner hole of the button contact base, diminishing the difficulty of assembling the spring button contact and enhancing the production efficiency of gas-insulated metal-enclosed switchgear.
Description
Technical field
The utility model relates to the high-voltage switch gear field, relates generally to a kind of arrangements of electric connection of gas-insulated metal enclosed switchgear, especially the fingertip seat that arrangements of electric connection is used on this gas-insulated metal enclosed switchgear.
Background technology
The main effect of the arrangements of electric connection of gas-insulated metal enclosed switchgear (GIS) is conducting rated current and a transient fault electric current in major loop, its electric property and mechanical performance to electrical connector has very high requirement, and the quality of its quality directly influences the reliability of GIS and the safe operation of electrical network.
At present, the electrical connector in domestic 72.5Kv and the above GIS equipment adopts plum blossom fingertip or watchband fingertip structure to connect usually.But, its parts of connected mode of plum blossom fingertip structure are more, complex structure, and cost of manufacture height and through-current capability are relatively poor; Though the connected mode of watchband fingertip structure is with low cost, it is had relatively high expectations to the fit clearance that connects, and is difficult to assembling in practice of construction.
Our company is at the defective of above-mentioned connected mode, applied for that on April 27th, 2007 application number is the utility model patent of 200720090154.X, does this patent application disclose a kind of? the arrangements of electric connection of Cubicle Gas-Insulated Switchgear? as shown in Figure 1, in this arrangements of electric connection, be used on the fingertip seat 1 to peg graft and be arranged at intervals with a plurality of independent annular grooves 2 on the inner hole wall of conducting rod 3, the cell wall of adjacent two annular grooves 2 connects by the bridge joint plane of an annular, the bottom surface of each annular groove 2 is a V-arrangement, and groove is equipped with spring touch finger 4.For guaranteeing that conducting rod and fingertip seated connection touch well, increase the through-current capability of conducting rod and fingertip seat, need to be provided with plural groove in the endoporus of fingertip seat at least.Though the connected mode structure of spring touch finger is comparatively simple and through-current capability is strong, but, be positioned at the annular groove processing difficulty comparatively on the fingertip seat inner hole wall, be difficult to processing more the closer to the groove of bottom, and the installation difficulty of spring touch finger increase with the degree of depth of endoporus also.
As shown in Figure 2, in research, find the annular groove of fingertip seat, spring touch finger is to utilize the compression of two paired springs of beveled of V-type groove bottom of annular groove and through-flow, and not compression and the through-flow effect of the cell wall on annular groove both sides, therefore, how to improve the structure of the annular groove in the fingertip seat endoporus, so that the production and processing of annular groove makes spring touch finger can be installed in easily becomes us in this annular groove research direction.
The utility model content
The purpose of this utility model provides a kind of arrangements of electric connection and fingertip seat thereof of gas-insulated metal enclosed switchgear, and the circular groove structure that is used for the mounting spring fingertip on this fingertip seat is simple, can reduce the axial width of fingertip seat, and is easy to processing.
The technical solution of the utility model is: a kind of fingertip seat, this fingertip seat is provided with the endoporus of the conducting rod that is used to peg graft, be set side by side with the annular groove that multiple tracks is used for the mounting spring fingertip on the sidewall of this endoporus vertically, described each annular groove is provided with continuously for no gap, and the notch of adjacent bipassage ring connected in star links to each other and has same linear groove edge.
The bottom surface of described each annular groove is a V-arrangement.
The utility model also provides a kind of arrangements of electric connection of gas-insulated metal enclosed switchgear, comprise fingertip seat and conducting rod, the fingertip seat is provided with the endoporus of grafting conducting rod, be set side by side with the annular groove that multiple tracks is used for the mounting spring fingertip on the sidewall of this endoporus vertically, described each annular groove is provided with continuously for no gap, and the notch of adjacent bipassage ring connected in star links to each other and has same linear groove edge.
The bottom surface of described each annular groove is a V-arrangement.
Adopt said structure, the utility model is on the basis that does not change former single groove application principle, the multi-groove structure that a plurality of intervals are provided with is improved to the single sipes structure that is processed into continuously, has reduced the axial width of former multi-groove structure fingertip seat, has simplified multi-groove structure; Simultaneously, reduce the mechanical processing difficulty of fingertip seat endoporus annular groove, reduced the assembly difficulty of spring touch finger, improved the production efficiency of Cubicle Gas-Insulated Switchgear.

Embodiment
As shown in Figure 3, Figure 4, in the arrangements of electric connection of gas-insulated metal enclosed switchgear of the present utility model, no gap is provided with multiple tracks annular groove 20 continuously on the endoporus sidewall of fingertip seat 1, and the notch of its adjacent bipassage ring connected in star 20 links to each other and has same linear groove edge.The bottom surface of each annular groove 20 is a V-arrangement, is separately installed with spring touch finger 4 in each V-shaped groove, and conducting rod 3 is plugged in the endoporus of fingertip seat 1, and closely is electrically connected with the fingertip seat by spring touch finger 4.Fingertip seat has in the present embodiment adopted the three-flute structure, and the V-shaped groove bottom surface of adjacent two annular grooves is connected to form W shape structure.
The illustrated structure of the utility model is on the basis of the application principle that does not change former single groove structure, single groove architecture advances that a plurality of intervals are provided with is a sipes structure that is processed into continuously, if dual-slot structure, then reduce the processing of the cell wall between two single grooves in the former dual-slot structure, if the three-flute structure, then reduce the processing of cell wall between the former three-flute, thereby reduced the axial width of multi-groove structure fingertip seat, simplified multi-groove structure.
