Description
Technical field
The utility model is a kind of wall bushing of substation plugging plate and earth terminal combining structure, belongs to transformer station's set through walls
The innovative technology of pipe plugging plate and earth terminal combining structure.
Background technology
Wall bushing is usually used on the wall at transformer station 10kV and 35kV main transformer inlet wire and overhead outlet, by sleeve of main transformer
Lead-out wire enters at 10kV and 35kV rooms, and outdoor overhead outlet is drawn out to by switch cubicle in power distribution equipment room.Because place is returned
The load on road is larger, and the electric current that bus is carried is also corresponding larger, so in electric substation's process of construction, installing bus set through walls
Guan Shi, it is desirable to opening brazing is carried out on the steel plate that it is installed.
Reason is that the surrounding space of heavy-current bus-bars has powerful alternating magnetic field, and the steel component being located therein will be by
Generated heat in vortex and magnetic hystersis loss.For the steel of the closed-loop path being made up of steel structure, such as bus support structure and protection cover bar
Frame etc., it is also possible to which sensing produces circulation and generated heat.This loss and heating can increased dramatically as bus operating current increases,
The current-carrying capacity of wire and the normal work of electric original paper are influenceed, or even jeopardizes personal safety.
In order to improve the generation of loss and heating, prevent that every phase conductor from supporting that steel structure and conductor support zero component structure of clamping plate
Into closed magnetic circuit, in order to avoid influence the safety and economic operation of device.Direct method is to replace steel and iron parts using nonmagnetic substance, but
This kind of mechanical property of materials, heat-resisting and ageing resistance are poor.It is actual with reference to substation project, improve above mentioned problem it is most effective again
Simple method, disconnection closed-loop path of exactly being adopted an effective measure on original structure, separates magnetic circuit, it is to avoid big with brass weld seam
The closed-loop path of a phase or two-phase is surrounded in steel member formation near current bus bar.
But in work progress, due to some cause specifics, when not possessing brazing conditions, can be replaced with aluminium sheet material
Recopper is welded.Aluminium is not the material of magnetic conduction in itself, is enough in terms of intensity and anticorrosion, the use of aluminium sheet is with respect to brazing process
Few easy to operate, the replacement for making brazing of aluminium sheet when installing wall bushing is feasible.
The content of the invention
The purpose of this utility model is to consider above mentioned problem and provide a kind of wall bushing of substation plugging plate and ground connection
Hold combining structure.The utility model both can guarantee that wall bushing armor plate strength and corrosion resistance, can prevent that three-phase conductor from supporting again
The parts such as steel member or clamping plate constitute closed magnetic circuit, reduce temperature rise, improve the safe running performance of device.
The technical solution of the utility model is：Wall bushing of substation plugging plate and earth terminal combination knot of the present utility model
Structure, to include and be provided with through hole on wall bushing steel plate, wall bushing, copper pipe bus, wall bushing steel plate, wall bushing is arranged on
On through hole, copper pipe bus is installed in wall bushing.
Slotted between the utility model several through holes set on wall bushing steel plate, the groove opened inlays aluminium sheet use
Stainless steel screw is fixed, and is substituted brazing process, both can guarantee that wall bushing armor plate strength and corrosion resistance, and can prevent that three-phase from leading again
Body supports that the parts such as steel member or clamping plate constitute closed magnetic circuit, reduces temperature rise, improves the safe running performance of device.This practicality
New is a kind of ingenious, the function admirable of design, convenient and practical wall bushing of substation plugging plate and earth terminal combining structure.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Embodiment：
Structural representation of the present utility model is as shown in figure 1, wall bushing of substation plugging plate of the present utility model and connect
Ground terminal combining structure, to include and be provided with through hole on wall bushing steel plate 1, wall bushing 2, copper pipe bus 3, wall bushing steel plate 1,
Wall bushing 2 is arranged on through hole, and copper pipe bus 3 is installed in wall bushing 2.
In the present embodiment, above-mentioned wall bushing steel plate 1 is rectangle steel plate, and need to carry out rust cleaning polishing and antirust treatment.
Several through holes are provided with above-mentioned wall bushing steel plate 1, some wall bushings 1 are separately mounted to several through holes
On.Fluting is processed between several through holes being provided with above-mentioned wall bushing steel plate 1 along along the connecting line of the center of circle, then uses stainless steel spiral shell
Aluminium sheet 6 is fixed at fluting by nail 7.In the present embodiment, three through holes are provided with above-mentioned wall bushing steel plate 1.Above-mentioned set through walls
Fluting is processed between three through holes being provided with pipe steel plate 1 along along the connecting line of the center of circle, then is fixed aluminium sheet 6 with stainless steel screw 7
At fluting.
In the present embodiment, arrester 4 is installed on above-mentioned copper pipe bus 3.
In the present embodiment, device 5 under the special grounding lead of inspection earthing is drawn by the downlead of above-mentioned arrester 4 again.
The utility model determines the position of wall bushing 2 when making according to design requirement, and wall bushing steel plate 1
Size；Three through holes, the big 5mm of aperture ratio wall bushing 2 are processed on wall bushing steel plate 1；Center of circle connecting line between three through holes
Upper processing fluting 50mm, then the wide aluminium sheets 6 of 50mm are fixed at fluting with stainless steel screw 7；Monoblock wall bushing steel plate 1 is removed
Brush antirust paint after rust polishing；After wall bushing steel plate 1 is installed in place with wall bushing 2, steel plate indoor-side gap is filled out with atomized ash
Full floating carry out water-proofing treatment；Three copper pipe bus 3, according to the installation requirement of three-phase alternating-current supply, are respectively arranged in set through walls
In pipe 2, and it is screwed respectively；Drawn again under the special grounding lead of inspection earthing by the downlead of arrester 4 of copper pipe bus 3
Device 5, in order to which operating maintenance ground connection provides reliability, efficiently earth point.
The fluting of wall bushing steel plate 1 fills up aluminium sheet 6, because aluminium is not the material of magnetic conduction, there is enough intensity and anticorrosion.
In the installation process of wall bushing steel plate 1, the use of aluminium sheet 6 is few with respect to brazing process and easy to operate, can effectively solve copper
Weld the shortcoming of construction technology.
