Busbar connection
A busbar connection includes first and second busbars each with a free end, and a shield device. The free ends of the busbars are directed towards each other and are in electrical contact with each other. The shield device envelopes the free ends of the busbars and is configured to steer the electrical field. The shield device includes a body of electrical conducting material. The body has two oppositely arranged contact surfaces in direct electrical contact with the free ends of the busbars. The body has a flange surrounding the contact surfaces and providing an upright edge around the contact surfaces.
1. An electrical busbar connection comprising:
first and second busbars each with a free end, wherein the free ends of the busbars are directed towards each other and are in electrical contact with each other; and
a shield device enveloping the free ends of the busbars and being configured to steer the electrical field, the shield device including a body of electrical conducting material, the body having two oppositely arranged contact surfaces in direct electrical contact with the free ends of the busbars and the body having a flange surrounding the contact surfaces and providing an upright edge around the contact surfaces'
wherein the shield device includes a ring of insulation material running around and spaced away from the free ends of the busbars, and
wherein the shield device includes a disc of electrical conducting material positioned between and in direct contact with the free ends of the busbars, the disc having an edge, wherein the ring of insulation material is arranged on the edge of the disc.
2. The electrical busbar connection according to claim 1 , wherein the shield device is substantially centered relative to a transition zone between both free ends of the first and second busbars.
3. The electrical busbar connection according to claim 1 , wherein the flange has a convex surface extending between the first and second busbar.
4. The electrical busbar connection according to claim 1 , further comprising a connection plate bolted to each of the busbars so as to connect the first busbar with the second busbar.
