Abstract
Disclosed is a GIS heavy-current contact structure. The GIS heavy-current contact structure comprises a cylindrical shell. Conductors in the cylindrical shell are connected by use of a plug-in mode; a plug contact portion is made of a copper material; the diameter of a contact is smaller than the diameter of the conductors; the end surface of the contact is provided with a recess; the recess is internally provided with a penetrating bolt hole; the contact is fixed on one conductor end surface; the outer circle of the contact is provided with touch fingers; the other conductor end surface is provided with a contact hole cooperating with the contact; the contact is connected with the contact hole through the touch fingers; the conductors at two sides are both made of an aluminum material; and the outer circle of the contact is provided with the two segments of touch fingers. According to the utility model, under the condition that an original equipment structure is not changed, a high-conductivity material is partially employed so that the heavy current requirement is satisfied, and the use amount of a precious metal with a high conductivity is reduced at the same time, thus the manufacturing cost is reduced.
Description
Technical field
The utility model relates to the gas-insulating and fully-enclosed combined electrical apparatus of a kind of GIS() equipment, relate in particular to the large current contact structure that GIS equipment is used.
Background technology
At present, along with the develop rapidly of national economy, under the continuous progressive support of high voltage technique, also day by day improve for the requirement of power transmission and transformation.GIS is as the infrastructure device of power transmission and transformation, and its developing direction is large capacity, miniaturization, intellectuality.National grid, south electric network, become increasingly conspicuous for the requirement of large capacity, miniaturization in the recent period.The requirement of 126kV GIS rated current 3150A, the requirement of 252kV GIS rated current 5000A often occurs.The large current design of GIS mainly contains to be accelerated heat radiation and reduces by two kinds of consideration methods of heating.Have the cylindrical shell of increase, cross-sectional area of conductor to amass for accelerating heat radiation Main Means, but will cause the corresponding increase of its built-in electrical insulation part size, the overall dimension of GIS changes and becomes greatly, and material cost increases sharply, and deviates from the direction of miniaturization; Be mainly in the situation that maintaining existing product physical dimension and not increasing for the method that reduces heating, reduce conductor resistance, improve conductance, temperature rise requirement when conductor material meets large electric current.The enforcement of this kind of scheme is generally conductor material is changed to the material that conductance is higher, and this will increase the consumption of precious metal greatly, increases manufacturing cost, causes conductor mass penalty simultaneously, increases factory, on-the-spot installation difficulty.
Utility model content
The utility model provides a kind of GIS large current contact structure, is large electric current, miniaturization GIS design specially, reduces precious metal use amount simultaneously, reduces equipment cost.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme: a kind of GIS large current contact structure, comprise cylindrical shell, in cylindrical shell, be provided with two sections of conductors that diameter is suitable, the end face of one conductor is provided with copper contact, and the diameter of contact is less than the diameter of conductor, and contact inner face is provided with depression, in depression, be provided with the screw hole running through, contact is bolted on fixed conductor end face; The cylindrical of contact is provided with fingertip; Another conductor end face is provided with the contact apertures with contacts mates, and contact is connected with contact apertures contact by fingertip.
Conductor adopts aluminum material, and contact is connected with conductor by bolt.
Two sections of fingertips are set on the cylindrical of contact.
The utility model is not in the situation that changing existing equipment structure, and part adopts high conductivity material, has both met large current requirements, reduces precious metal use amount simultaneously, has also reduced manufacturing cost.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Embodiment: as shown in Figure 1, a kind of GIS large current contact structure, comprise cylindrical shell 1, in cylindrical shell 1, be provided with conductor 2 and conductor 5 that diameter is suitable, the end face of conductor 2 is provided with copper contact 3, and the diameter of contact 3 is less than the diameter of fixed conductor 2, and contact 3 end faces are provided with depression, in depression, be provided with the bolt hole running through, contact 3 is bolted on conductor 2 inner faces; The cylindrical of contact 3 is provided with fingertip 4; Conductor 5 end faces are provided with the contact apertures coordinating with contact 3, and contact 3 is connected with conductor 5 by fingertip 4.Fixed conductor 2 and conductor 5 are aluminum material, and contact 3 is copper material, to reduce temperature rise, meets instructions for use.
Fixed conductor 2 and conductor 5 are common used material (Al), and contact 3 adopts high conductivity material (Cu) to make.Contact 3 adopts and is bolted on conductor, is realized and being slidably connected with conductor 5 by fingertip 4.Due to conductor 2 and conductor 5 diameters larger, adopt comparatively cheap material (Al) to meet the demands, contact 3 section diameters are less, adopt electric conductivity good copper material also can meet conductor demand.Reduce like this use amount of copper material, alleviated conductor weight, reached the requirement of large electric current miniaturization simultaneously.
