Abstract
The utility model relates to a gas insulated switchgear (GIS) terminal contact. The contact comprises an upper electrode, wherein the upper electrode is provided with an inner cavity with a single open end; a conductor-stalk stretches into the inner cavity; a plurality of annular grooves are formed at the end of the conductor-stalk; a spring contact finger made of an elastic material is arranged in each groove; and the end of the conductor-stalk is firmly arranged in the inner cavity through the spring contact fingers. The spring contact fingers are adopted, the conductor-stalk is easily processed, and the contact is conveniently mounted on site; the spring contact fingers occupy a small space of the conductor-stalk, the number of springs can be increased, and the requirements of large section and high current are met; and in addition, the elastic force of the spring contact fingers is lasting, contact pressure is well kept, the contact area is slightly changed, and electrical property is stable.
Description
Technical field
The utility model relates to a kind of superhigh pressure power transmission and distribution parts, and specifically a kind of GIS terminal is touched son.
Background technology
Power cable GIS terminal is the parts that power cable and GIS equipment connection are used.Its structure is: outside is the epoxy insulation cover, and epoxy insulation cover the inside is cable and the cable stress cone of handling well, and the epoxy insulation cover inserts the GIS device interior that is full of sulfur hexafluoride gas.Inside and outside general, be (being path inside and outside few part) of isolating fully.Epoxy insulation cover top is that conduction is touched son, and purpose is communicated with GIS equipment bus-bars conductor the cable core conductor on electric.
Existing tactile son is that the tactile son of watchband type is strict to the processing dimension of outlet stalk, and the on-the-spot fitting operation time is long, to demanding strict technology of on-the-spot installer.The elastic force endurance of watchband is short, and it is fast that contact decays.If the contact of watch band contact diminishes, can cause contact area inadequate, the excessive core that causes of contact resistance generates heat, and dielectric strength descends until puncture.
The utility model content
The manufacturing procedure that technical problem to be solved in the utility model is to provide a kind of outlet stalk is simple, easy for installation, and the GIS terminal of electric performance stablity is touched son.
A kind of GIS terminal described in the utility model is touched son, comprise upper electrode, this upper electrode has the inner chamber of a single-ended opening, the outlet stalk stretches in this inner chamber, described outlet stalk end is provided with some roads annular groove, be provided with the spring touch finger of being made by elastic material in groove, outlet stalk end firmly is arranged in inner chamber by spring touch finger.
The annular groove of described outlet stalk end has twice at least.
The utility model adopts spring to touch son, and the manufacturing procedure of outlet stalk is easy, on-the-spot easy for installation.It is few that the tactile son of spring takies outlet stalk space, can increase the demand that number of springs meets the large electric current in heavy in section, and it is lasting that this outer spring touches sub elastic force, and it is good that contact keeps, and contact area changes little, electric performance stablity.
The accompanying drawing explanation
Fig. 1 is structure adaptability of the present utility model.
Embodiment
As shown in Figure 1, GIS terminal of the present utility model is touched son, main body comprises upper electrode 1 and outlet stalk 2, upper electrode 1 has the inner chamber of a single-ended opening, outlet stalk 2 stretches in this inner chamber, outlet is obstructed 2 ends and at least is provided with the bipassage ring connected in star, is provided with the spring touch finger 3 of being made by elastic material in groove, and outlet is obstructed 2 ends and firmly is arranged in inner chamber by spring touch finger 3.
The utility model; concrete application approach is a lot; the above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle, can also make some improvement, these improvement also should be considered as protection range of the present utility model.
Claims (2)
1. a GIS terminal is touched son, comprise upper electrode (3), this upper electrode (3) has the inner chamber of a single-ended opening, outlet stalk (2) stretches in this inner chamber, it is characterized in that, described outlet stalk (2) end is provided with some roads annular groove, is provided with the spring touch finger (1) of being made by elastic material in groove, and outlet stalk (2) end firmly is arranged in inner chamber by spring touch finger (1).
2. GIS terminal according to claim 1 is touched son, it is characterized in that, the annular groove of described outlet stalk (2) end has twice at least.
