Description

Composite shielding sealing insulating tube type busbar joint
Technical field
The utility model relates to a kind of auxiliary equipment of power transmitting device, belongs to especially a kind of shield type joint of tube type bus.
Background technology
In the transformation and process of construction of electrical network, the long-term a large amount of capital equipments that adopt square type bus to connect as electric equipment of China.But there is obvious shortcoming in square type bus: kelvin effect is obvious, and eddy current loss is serious.From the whole nation, the electric weight losing due to line loss is very huge.Therefore, grid company gradually adopts copper or aluminum metal tubulose bare bus bar to substitute square type bus, aspect reducing the wastage, has stepped major step.But employing bare bus bar, its Supply Security does not improve.For this reason, China starts to carry out research and the application of the insulating protection of metal pipe bus.Solid insulation Intelligent Bus system is constantly to expand in order to adapt to substation capacity, low-voltage side outlet electric current continues to increase and the novel product developed, it is not only for enlarging and the increase-volume in power station provide strong support and assurance, give the new ideas that are aided with safety and environmental protection of laying of electric equipment, can save the metals resources of a large amount of preciousnesses again simultaneously, be the direction of power transmission and distribution industry future development, and the joint of bus is that impact is for a key factor of transmission of electricity stability.
Summary of the invention
The purpose of this utility model is to provide a kind of composite shielding sealing insulating tube type busbar joint, to reach the object that guarantees that connector is safe and reliable, contact resistance is little, temperature rise is low.
Composite shielding sealing insulating tube type busbar joint provided by the utility model, it is characterized in that, have fixture and insulating shield cylinder, described insulating shield cylinder has copper pipe main insulation, main insulation shielding, splice insulation, splice insulation shielding and oversheath from inside to outside; Described fixture refers to that the middle part of two ends splice insulation, for connecting gold utensil, connects gold utensil two ends setscrew nut is set; Between oversheath internal layer and main insulation shielding, be provided with semiconductive cone.
Composite shielding sealing insulating tube type busbar joint provided by the utility model, be arranged in use between two sections of tube type bus that need to connect, by being fixed after connecting of connection gold utensil and setscrew nut, then adopt the mode installing insulating shielding cylinders such as bonding or sulfuration; The method that the utility model adopts shielding to connect, the sectional area of connector and contact area are greater than conductor itself, junction contact resistance is little, guarantee the safe and reliable of connection bus, and the temperature rise in when work is lower than conductor temperature rise, also guaranteed when it expands with heat and contract with cold connective stability, therefore, there is good effect safe and reliable, that contact resistance is little, heat generation rate is low.
Accompanying drawing explanation
Accompanying drawing partly discloses specific embodiment of the utility model, wherein,
Fig. 1, the utility model is installed and used state diagram.
Embodiment
As shown in the figure, the utlity model has fixture and insulating shield cylinder, described insulating shield cylinder has copper pipe main insulation 2, main insulation shielding 3, splice insulation 5, splice insulation shielding 6 and oversheath 4 from inside to outside; Described fixture refers to that the middle part of two ends splice insulation, for connecting gold utensil 8, connects gold utensil and is positioned at copper pipe 1 outside, connects gold utensil two ends setscrew nut 7 is set, and the two cooperation is used for being fixedly connected with two ends bus; Between oversheath internal layer and main insulation shielding, be provided with semiconductive cone 9.
Above-mentioned connection gold utensil and main insulation shielding can be for copper forms, and oversheath adopts heat-shrink tube to be made, and copper pipe main insulation is silicon rubber.
