Abstract

A medium voltage switchgear busbar disconnector system includes a busbar and a disconnector moveable part; wherein the busbar comprises a contact; wherein in a connected state the disconnector moveable part is configured to be connected to the contact; and wherein in a disconnected state the disconnector moveable part is configured to be disconnected from the contact.

First claim

What is claimed is:

1. A switchgear busbar disconnector system for a medium voltage application, comprising:
a busbar; and
a disconnector moveable part;
wherein the busbar comprises a contact, a first part located on a first side of the contact of the busbar, and a second part located on a second side of the contact of the bus bar;
wherein in a connected state the disconnector moveable part is configured to be connected to the contact; and
wherein in a disconnected state the disconnector moveable part is configured to be disconnected from the contact and the busbar is configured such that all the current passes from the first part of the busbar to the second part of the busbar goes through the contact of the busbar.

2. The switchgear busbar disconnector system according to claim 1 , wherein the second side of the contact of the busbar is on an opposite side of the contact of the busbar to the first side of the contact of the busbar.

3. The switchgear busbar disconnector system according to claim 1 , wherein in the disconnected state a current path from the first part of the busbar to the second part of the busbar goes through the contact of the busbar.

4. The switchgear busbar disconnector system according to claim 1 , wherein the first part of the busbar is not directly connected to the second part of the busbar.

5. The switchgear busbar disconnector system according to claim 1 , wherein the first part of the busbar is directly connected to the contact of the busbar, and wherein the second part of the busbar is directly connected to the contact of the busbar.

6. The switchgear busbar disconnector system according to claim 1 , wherein a transition from the disconnected state to the connected state comprises a first linear movement of the disconnector moveable part, wherein a transition from the connected state to the disconnected state comprises a second linear movement of the disconnector moveable part, and wherein the second linear movement is in an opposite direction to the first linear movement.

7. The switchgear busbar disconnector system according to claim 6 , wherein the contact of the busbar has a hole that extends from a front side of the contact of the busbar to a rear side of the contact of the busbar, and wherein the first linear movement of the disconnector moveable part comprises an insertion of the disconnector moveable part into the hole of the contact of the busbar from the front side of the contact of the busbar.

8. The switchgear busbar disconnector system according to claim 7 , wherein the second linear movement of the disconnector moveable part comprises an extraction of the disconnector moveable part from the hole of the contact of the busbar out from the front side of the contact of the busbar.

9. The switchgear busbar disconnector system according to claim 7 , wherein the hole has at least one circular cross section and wherein the disconnector moveable part comprises a circular cross section that corresponds to a circular cross section of the at least one circular cross section of the hole.

10. The switchgear busbar disconnector system according to claim 6 , wherein the first linear movement of the disconnector moveable part comprises an insertion of the disconnector moveable part into a hole of the contact of the busbar from a front side of the contact of the busbar and movement of the disconnector moveable part to a rear side of the contact of the busbar.

11. The switchgear busbar disconnector system according to claim 10 , wherein the second linear movement of the disconnector moveable part comprises a movement of the disconnector moveable part away from the rear side of the contact of the busbar and an extraction of the disconnector moveable part from the hole of the contact of the busbar out from the front side of the busbar.

12. A switchgear busbar disconnector system comprising:
a busbar; and
a disconnector moveable part;
wherein the busbar comprises a contact, a first part located on a first side of the contact of the busbar, and a second part located on a second side of the contact of the bus bar;
wherein in a connected state the disconnector moveable part is configured to be connected to the contact; and
wherein in a disconnected state the disconnector moveable part is configured to be disconnected from the contact; and
wherein a front side of the contact of the busbar is coplanar with a front side of the first part of the busbar, and wherein the front side of the contact of the busbar is coplanar with a front side of the second part of the busbar.

13. A switchgear busbar disconnector system comprising:
a busbar; and
a disconnector moveable part;
wherein the busbar comprises a contact, a first part located on a first side of the contact of the busbar, and a second part located on a second side of the contact of the bus bar;
wherein in a connected state the disconnector moveable part is configured to be connected to the contact; and
wherein in a disconnected state the disconnector moveable part is configured to be disconnected from the contact; and
wherein a rear side of the contact of the busbar is coplanar with a rear side of the first part of the busbar, and wherein the rear of the contact of the busbar is coplanar with a rear side of the second part of the busbar.

14. A busbar for a medium voltage switchgear, comprising:
a contact, a first part located on a first side of the contact of the busbar and a second part located on a second side of the contact of the busbar;
wherein the busbar is configured to be connected to and disconnected from a disconnector moveable part;
wherein in a connected state the contact is configured to be connected to the disconnector moveable part; and
wherein in a disconnected state the contact is configured to be disconnected from the disconnector moveable part and the busbar is configured such that all the current that passes from the first part of the busbar to the second part of the busbar goes through the contact of the busbar.

15. The busbar according to claim 14 , wherein the second side of the contact of the busbar is on an opposite side of the contact of the busbar to the first side of the contact of the busbar.

16. The busbar according to claim 14 , wherein in the disconnected state a current path from the first part of the busbar to the second part of the busbar goes through the contact of the busbar.

17. A busbar for a medium voltage switchgear, comprising:
a contact, a first part located on a first side of the contact of the busbar and a second part located on a second side of the contact of the busbar;
wherein the busbar is configured to be connected to and disconnected from a disconnector moveable part;
wherein in a connected state the contact is configured to be connected to the disconnector moveable part;
wherein in a disconnected state the contact is configured to be disconnected from the disconnector moveable part; and
wherein a front side of the contact of the busbar is coplanar with a front side of the first part of the busbar, and wherein the front side of the contact of the busbar is coplanar with a front side of the second part of the busbar.

18. A busbar for a medium voltage switch gear, comprising:
