Description

Busbar connection
The invention relates to a busbar connection
comprising :
- a first and second busbar ends with a longitudinal direction and with a through hole arranged in each busbar end;
- mounting means, in particular, a bolt and nut, extending through all the through holes of the busbar ends to clamp the busbar ends together;
wherein each busbar end comprises a contact surface arranged around the respective through hole and directed towards the contact surface on the adjacent busbar end,
wherein an electrically insulating layer is arranged on the outer surface of each busbar end, which electrically insulating layer extends up to the contact surface.
Such a busbar connection is generally known and has typically busbar ends with a rectangular cross-section bolted together. Such busbar connections are used in for example switchgear housings to connect busbars of adjacent switchgear housings or for connecting switchgear to the busbars. These busbars are typically insulated such that the switchgear housing can be opened for maintenance without direct danger to the maintenance personnel.
However, at the busbar connection, the contact surfaces are uncovered to provide electrical contact surfaces. Due to tolerances, still some parts near the contact surfaces will not be covered with insulation material and leave some parts of the busbar ends not insulated when connected to each other .
These non-insulated parts cause a risk when maintaining parts near these non-insulated parts. When for example a wire gets loose or some tool falls, it could get into contact or too close to the non-insulated parts causing violent sparks, damaging the parts and causing possible bodily harm to maintenance personnel.
This risk is typically overcome by using shrink sleeved solutions or plastic arc free cap solutions (plastic box like structures), which are complicated to assemble, expensive and prone to human error.
Prevention of an arc-flash is a far better measure than limiting the effects. Therefore, there is a need to reduce the bare copper area and have a cost-effective, easy to assemble and a completely arc free design, to ensure complete safety during maintenance and service.
The object of the invention is therefore to reduce the above-mentioned disadvantages of the prior art.
This object of the invention is achieved with a busbar connection according to the preamble, which is
characterized in that at least one of the contact surfaces is stepped relative to the surrounding outer surface of the busbar end and in the axial direction of the through hole, in order to be in electrical contact with the contact surface of the adjacent busbar end.
By providing a stepped contact surface, the contact surface will no longer be in the same plane as the outer surface of the busbar end. As a result, the size of the contact surfaces is no longer defined by the size of the busbar ends. So, the contact surface dimensions can be
designed such that any bare copper areas resulting from the tolerance of the insulation layer are covered by the adjacent busbar ends .
The stepped contact surface also allows for to compensate for the thickness of the insulation layer, while the contact surfaces of both busbars end need to be bare.
In a preferred embodiment of the busbar connection according to the invention, the contact surface of the first busbar end is stepped outwardly relative to the surrounding outer surface.
With the contact surface of the first busbar end being stepped outwardly, the contact surface will protrude above the outer surface of the busbar end. This allows for the contact surface to be positioned at such a height, that a small gap can be present between the busbar ends, but that the width of this gap is small enough to prevent any foreign parts to enter the gap, contacting the bare surface and causing arcing .
In a further embodiment of the busbar connection according to the invention, the contact surface of the second busbar end is stepped inwardly relative to the surrounding outer surface.
With the contact surface of the second busbar end stepped inwardly, a cavity is provided in the second busbar, into which cavity the protrusion formed by the contact surface of the first busbar end can extend. This will further reduce access to bare surface parts of the busbar ends in the mounted state of the busbar connection. It also provides a shape defined positioning of the busbar ends relative to each other, which facilitates mounting of the busbar connection.
A next preferred embodiment of the busbar connection according to the invention further comprising an electrically conducting spacer ring arranged between the contact surfaces of the first and second busbar ends, wherein at least the contact surface of the first busbar is stepped inwardly relative to the surrounding outer surface.
An inwardly stepped contact surface is more easily provided on a busbar end. With the additional spacer ring, an electrical connection can be achieved similar to the
embodiment with the outwardly stepped contact surface. The spacer ring will be kept in position by the cavity provided by the inwardly stepped contact surface.
In a further preferred embodiment of the busbar connection according to the invention, the contact surface of the second busbar end is stepped inwardly relative to the surrounding outer surface.
Having the contact surfaces of both busbar ends inwardly stepped, which is more easily manufactured, the spacer ring will still provide the required electrical contact between the contact surfaces, while all bare parts of the busbar ends and spacer ring are enveloped by the insulated parts of the busbar ends, such that no arcing can occur.
In yet another embodiment of the busbar connection according to the invention, the axis of each through hole is perpendicular to the longitudinal direction of the respective busbar end.
Preferably, the contact surfaces are annular and concentrically arranged around the through hole of the
respective busbar end. Although other shapes, such as
triangular, square and the like, are possible for the contact surfaces, an annular contact surface allows for the busbar ends to be rotated relative to each other around the axis of the through holes. This facilitates mounting of the busbar connection and allows for taking up any deviations in
dimensions .
In yet another preferred embodiment of the busbar connection according to the invention, the main dimension of the contact surfaces is smaller than the width of both the busbar ends. This allows for the bare parts of the busbar ends to be fully covered by the opposite busbar end.
Preferably, the at least one stepped contact surface spaces the busbar ends apart, wherein the gap between the busbar ends is less than 1 mm. This ensures that the gap is too small for a wire of 1 mm diameter or more to contact the live parts.
These and other features of the invention will be elucidated in conjunction with the accompanying drawings.
Figures 1A, IB and 1C show the first embodiment in an exploded view, a cross-sectional view, and a side view.
Figure 2 shows an enlarged and more detailed cross- sectional view of the first embodiment according to figure 1.
Figures 3 - 5 show cross-sectional views of a second, third and fourth embodiment of the invention.
Figure 1A shows an exploded view of the first embodiment of a busbar connection 1 according to the
invention. The busbar connection 1 has a first busbar end 2 and a second busbar end 3. Each busbar end 2, 3 is provided with a through hole 4, 5 respectively (see also figure IB) .
Around the respective through holes 4, 5 an inwardly stepped contact area 6, 7 is provided. A spacer ring 8 is positioned into the cavities formed by the inwardly stepped contact area's 6, 7 to provide electrical contact between the two busbar ends 2, 3.
A bolt 9 is mounted through the through holes 4, 5 and clamps with the nut 10 the first busbar end 2, the second busbar end 3 and the spacer ring 8 together.
Insulating caps 11, 12 are arranged over the bolt 9 and nut 10 respectively to ensure that no bare part is accessible .
Figure 1C shows the busbar ends 2, 3 and space ring 8 in a side view. Clearly, the gap G between the first busbar end 2 and the second busbar 3 is kept so small, that no foreign parts, like an ignition wire, can get into contact with the spacer ring 8 or the contact surfaces 6, 7.
Preferably, this gap G is less than 1 mm.
Figure 2 shows an enlarged cross-sectional view of the busbar connection 1. The outer surface of both busbars ends 2, 3 are provided with an insulating coating 13, 14, which insulates the busbar ends 2, 3. The insulating caps 11, 12 furthermore insulate the mounting means 9, 10, while the thickness of the spacer ring 8 is designed such that the gap G is kept minimal and no foreign parts can get into contact with the electrically conducting parts or surfaces of the busbar connection 1.
Figure 3 shows a cross-sectional view of a second embodiment of a busbar connection 20 according to the
invention. The connection 20 has a first busbar end 21 and a second busbar end 22. The first busbar end 21 has an inwardly stepped contact surface 23, while the second busbar end 22 has a contact surface 24 which is provided flush with the outer surface of the second busbar end 22.
A spacer ring 25 is arranged between the contact surfaces 23, 24 to ensure electrical contact between the first busbar end 21 and the second busbar end 22, as well as a minimal gap G.
Figure 4 shows a cross-sectional view of a third embodiment of a busbar connection 30 of a first busbar end 31 and a second busbar end 32. The first busbar end 31 is
provided with an outwardly stepped contact surface 33, while the second busbar end 32 is provided with an inwardly stepped contact surface 34.
The protrusion formed by the contact surface 33 extends into the cavity formed by the contact surface 34, such that the relative position of both busbars ends 31, 32 is defined and mounting of the busbar connection 30 is
facilitated .
Figure 5 shows a fourth embodiment 40 of a busbar connection according to the invention. The busbar connection 40 has a first busbar end 41 and a second busbar end 42. The first busbar end 41 is punched, such that an outwardly stepped contact surface 43 is provided. This contact surface 43 is in contact with a contact surface 44 which is provided flush with the outer surface of the second busbar end 42 to provide an electrical connection between the busbar ends 41, 42.
Due to the outwardly stepped contact surface 43 a small gap G is provided allowing space for the insulating coating, while still keeping the gap G to minimal to avoid contact of foreign objects with the contact surfaces 43, 44.
