High-voltage installation with a desired breaking point
View Patent ↗A material-saving, cost-efficient and simultaneously safe high-voltage system for energy transfer includes a busbar and at least one high-voltage device connected to the busbar by an electrically conductive connecting device or connector. The connecting device or connector has a predetermined breaking point which is constructed in such a manner that the predetermined breaking point will break if a predetermined force is exerted between the busbar and the high-voltage device.
1. A high-voltage installation for energy transmission, the high-voltage installation comprising:
a busbar;
at least one high-voltage device; and
an electrically conductive connector connecting said at least one high-voltage device to said busbar;
said connector including at least one clamping unit having a flange section for connection to said at least one high-voltage device and a clamping section for connection to said busbar;
said connector having a desired breaking point configured to break said desired breaking point upon an occurrence of a predetermined force effect between said busbar and said at least one high-voltage device, said desired breaking point being disposed between said flange section and said clamping section over a course of a force transfer.
2. The high-voltage installation according to claim 1 , wherein said desired breaking point is a portion of weakened material in said connector.
3. The high-voltage installation according to claim 2 , wherein said portion of weakened material brings about a cross-sectional constriction of a current path extending beyond a path length of less than 10 mm.
4. The high-voltage installation according to claim 1 , wherein said busbar has at least one of at least one flexible conductor or at least one rigid conductor.
5. The high-voltage installation according to claim 1 , wherein said at least one clamping unit has a multipart construction, a clamping connecting device connects said flange section to said clamping section, and said desired breaking point is formed on said clamping connecting device.
6. The high-voltage installation according to claim 5 , wherein said at least one clamping unit has an integral construction with a connecting section integrally formed between said flange section and said clamping section, and said desired breaking point is formed in said connecting section.
7. The high-voltage installation according to claim 1 , wherein said at least one clamping unit is formed in one-piece and has a connecting section formed between said flange section and said clamping section, and said desired breaking point is formed in said connecting section.
