Abstract
The utility model provides a transformer bushing, comprising a conductive body, a porcelain member, a sealing ring, a press plate and a spring, characterized in that: the conductive body is of a hollow integral structure. The outer side of the lower part of the porcelain member sheathed on the conductive body is connected with a mounting flange through a perfusion mode. The bottom end of the porcelain member is provided with the press plate the bottom part of which is also sequentially provided with the spring and a fixing plate used to improve the sealing strength of the press plate. Compared with prior art, the high-current transformer bushing of the utility model has a simple structure, easy site installation, reliable electric apparatus performance, and strong tensile strength. The conductive body has favorable conductivity and heat dispersion, and also degrades partial discharging of the transformer bushing.
Description
Technical field
The utility model belongs to and send the power transformation technical field, specifically a kind ofly is used for the novel transformer sleeve pipe that transformer and related accessory are made.
Background technology
At present, the big electric current sleeve pipe that power transformer uses, all adopt aluminium material, its terminal block need be welded on the solid aluminum conductor with the method for welding, installing to adopt presses the angle mode to connect with transformer, its weak point has the following aspects: at first, because the metallic aluminium conductance is lower than metallic copper conductance, therefore the volume of the volume ratio copper electric conductor of same specification product aluminium electric conductor is much bigger; Secondly, terminal block need be welded on the electric conductor, and one conductivity is bad, and its two bad mechanical strength causes the sleeve pipe bending resistance to descend; Moreover the conduit connection plate is an aluminium material matter and the terminal block that connects with it is a copper material, therefore in use can produce the polarization reaction; In addition, because being solid, aluminium conductor therefore influences the sleeve pipe heat radiation.
Summary of the invention
The purpose of this utility model provides a kind of simple and reasonable, easy for installation, novel transformer sleeve pipe that mechanical strength is high.
The purpose of this utility model is achieved in that it comprises electric conductor, porcelain spare, sealing ring, pressing plate, spring, it is characterized in that electric conductor is hollow overall structure, the outside, bottom that is sleeved on the porcelain spare on the electric conductor is connected with mounting flange by reperfusion mode, be provided with a pressing plate in the bottom of porcelain spare, also set gradually in the bottom of pressing plate and be useful on spring, the fixed head that improves the pressing plate sealing intensity.
Above-mentioned fixed head is fixed on the lower end of electric conductor, is used for intensity to upper support (passing through spring) pressing plate sealing.
Strong current transformer sleeve pipe of the present utility model compared with prior art, it is simple in structure, the scene is easy for installation, electric property is reliable, tensile strength is big, electric conductor has excellent conducting performance and heat dispersion; But also reduced the partial discharge of sleeve pipe.
Description of drawings
Fig. 1 is a structural representation sketch of the present utility model
Fig. 2 is the electric conductor structure for amplifying sketch among Fig. 1
To be described in further detail utility model by example below; but following example only is the utility model example wherein; the rights protection scope of not representing the utility model and being limited, rights protection scope of the present utility model is as the criterion with claims.
Embodiment
Example 1
Shown in Fig. 1～2,1 among the figure is the copper electric conductor, and this copper electric conductor 1 is hollow overall structure; The outside, bottom that is sleeved on the porcelain spare 2 on the electric conductor 1 is connected with mounting flange 6 by reperfusion mode, be provided with a pressing plate 3 in the bottom of porcelain spare, set gradually spring 4 and the fixed head 5 that is useful on raising pressing plate sealing intensity in the bottom of pressing plate, fixed head 5 wherein is fixed on the lower end of electric conductor.Among the figure 7 is sealing ring in addition, the sealing function when playing the installation of electric conductor and porcelain spare.Mounting means and using method are identical with existing bushing shell for transformer.
