Description
Technical field
The utility model relates to a kind of electric cable accessories GIS terminal epoxy bushing, specifically, relates to the lower inserts metal electrode in a kind of epoxy bushing.
Background technology
Along with the fast development of national economy, the further quickening of urbanization process, urban network restructuring and rural power grids upgrading will obtain fast development, and this development for high-voltage and ultra-high network system provides larger opportunity.Electric cable accessories is as the important auxiliary products of network system, and its reliability determines the safe operation of electrical network.It strengthens lower inserts metal electrode the epoxy bushing that grid power transmission circuit system GIS terminal is used at present, as shown in Figure 1, adopt the frame mode of overall aluminium electrode, this frame mode is due to different from the cold and hot coefficient of expansion of epoxy material, and annex terminal is easy to crack, owing to adopting, its bonding force of embed wholly structure is not strong, easily peel off, thus the effect that can not bear support force and pulling force, and produce time this frock mounting process complexity, weight is heavier, and labour intensity is large, cost is high.
Utility model content
For addressing the above problem, the utility model provides a kind of resistance to tension, enabling capabilities is strong, mechanical strength good, the GIS terminal epoxy bushing bottom electrode of long service life.
GIS terminal epoxy bushing bottom electrode described in the utility model, comprises two electricity rings that be arranged in parallel, and two electricity rings are fixedly connected with by spaced conducting rod.
The screw-type structure of conducting rod, can make epoxy layer and the screw mandrel increase enclasping force of combining closely, and prevents that itself and epoxy bushing from peeling off, the effect that increases it and bear support force and pulling force; Because the existing bottom electrode of contact area rate of bottom electrode and epoxy bushing is little, tightr with contacting of epoxy bushing, the probability of epoxy bushing cracking reduces greatly, mechanical strength and the useful life of epoxy bushing entirety are improved, in the situation that mechanical strength is improved, its resistance to tension, enabling capabilities also obtain corresponding raising.Meanwhile, with respect to existing lower metal electrode, this Structure Decreasing the weight of bottom electrode, produce easy for installationly, can reduce production costs.
Preferably, the cage structure that described bottom electrode is taper type, more the fit structure of epoxy bushing of this structure, can make epoxy bushing tightr with being connected of bottom electrode.
Preferably, the quantity of described conducting rod is 2～10, and what be more preferably is 6, and described conducting rod is evenly arranged between two electricity rings.The quantity increase of conducting rod can be strengthened the intensity of bottom electrode entirety, and being uniformly distributed one is to increase aesthetics and balance, also makes bottom electrode stressed more even simultaneously, and mechanical strength is improved, and tension and anti-pressure ability are improved.
Preferably, described bottom electrode adopts pouring type to form, the inner and outer tubes close contact of bottom electrode and epoxy bushing.Conducting rod adopts and embeds screw-type, can make the combination of epoxy bushing and conducting rod tightr, increases its cohesive force.
Preferably, described electricity ring is aluminium conductor solid torus, and described conducting rod is aluminium conductor solid hopkinson bar.
Compared with prior art, the beneficial effects of the utility model are: 1) weight of bottom electrode is lower, adopt pouring type to produce, and install convenient for productionly, and cost is low, and production efficiency is improved; 2) bottom electrode is tightr with being connected of epoxy bushing, can increase the cohesive force of epoxy bushing, prevents epoxy part cracking, mechanical strength and the useful life of having improved epoxy bushing; 3) can make GIS annex terminal tension, enabling capabilities be improved, improve the safety and reliability of GIS terminal.
