Contact protection system for power busbars

1. A contact protection system for power busbars having planar contact protection modules which each comprise holding feet for engaging behind the power busbars and latching elements for mutually latching with adjacent contact protection modules,

wherein the contact protection modules comprise for each power busbar a terminal-receiving region for receiving connecting terminals which are provided for electrically contacting the respective power busbar, wherein the terminal-receiving regions of the contact protection modules comprise insertion devices, which are sloped in the manner of a roof, for inserting clamping brackets of the connecting terminals which are provided for fixedly clamping the connecting terminals to the power busbars.

2. The contact protection system as claimed in claim 1 , wherein the terminal-receiving regions of the contact protection modules each comprise contacting slots, which are arranged in parallel and offer protection against direct contact, for electrically contacting the power busbars by means of the connecting terminals.

3. The contact protection system as claimed in claim 2 , wherein the contacting slots of the terminal-receiving regions are offset from the holding feet in a direction parallel to a width direction of the slot.

4. The contact protection system as claimed in claim 2 , wherein the contacting slots of the contact protection modules are formed in such a manner that they provide a uniform division of all mutually latched contact protection modules.

5. A contact protection system for power busbars having planar contact protection modules which each comprise holding feet for engaging behind the power busbars and latching elements for mutually latching with adjacent contact protection modules,

wherein the contact protection modules comprise for each power busbar a terminal-receiving region for receiving connecting terminals which are provided for electrically contacting the respective power busbar,

wherein the connecting terminal comprises a contact plate having contact segments which are arranged in parallel and electrically contact through contacting slots of a contact protection module a power busbar located underneath.

6. The contact protection system as claimed in claim 1 , wherein the connecting terminals are each connected to a switching device which draws electric current from the power busbars.

7. The contact protection system as claimed in claim 1 , wherein the connecting terminal comprises a contact plate having contact segments which are arranged in parallel and electrically contact through contacting slots of a contact protection module a power busbar located underneath.

8. The contact protection system as claimed in claim 7 , wherein the contact plate of the connecting terminal is guided by two opposite guide grooves which are provided in opposite clamping brackets of the connecting terminal.

9. The contact protection system as claimed in claim 7 , wherein the contact plate of the connecting terminal is pressed against the power busbar by means of a screw and a spring disk.

10. The contact protection system as claimed in claim 9 , wherein a connection rail or a connecting plate can be clamped between the spring disk and the contact plate of the connecting terminal.

11. The contact protection system as claimed in claim 10 , wherein at least one prism clamp for a circular and sector-shaped conductor or a ribbon cable is attached to the connecting plate.

12. The contact protection system as claimed in claim 1 , wherein busbar carrier cover modules are provided for covering power busbar carriers, wherein the busbar carrier cover modules can be latched to adjacent contact protection modules by means of latching elements.

13. The contact protection system as claimed in claim 1 , wherein the contact protection modules can be slid on a plurality of power busbars, which are arranged in parallel in the horizontal direction, such that the holding feet of the contact protection modules engage behind the power busbars.

14. The contact protection system as claimed in claim 13 , wherein an edge profile can be inserted at a lower edge of the contact protection modules, which are slid onto the power busbars and are latched to one another, said edge profile can be latched in a non-positive-locking manner to busbar carrier cover modules and therefore the contact protection modules are prevented from inadvertently sliding down from the power busbars.

15. The contact protection system as claimed in claim 1 , wherein the contact protection modules can be covered and/or closed by means of an additional, completely closed cover.

16. The contact protection system as claimed in claim 1 , wherein each contact protection module of the contact protection system comprises for each power busbar to be covered in each case a plurality of holding feet for engaging behind the respective power busbar,

wherein a cover device for increasing the fault arc resistance can be attached to adjacent chambers of the contact protection modules.

17. The contact protection system as claimed in claim 1 , wherein the contact protection modules, the busbar carrier cover modules and edge profiles of the contact protection system consist of an electrically insulating, thermally stable and fire-retarding synthetic material.

18. A contact protection system for power busbars having planar contact protection modules which each comprise holding feet for engaging behind the power busbars and latching elements for mutually latching with adjacent contact protection modules,

wherein the contact protection modules comprise for each power busbar a terminal-receiving region for receiving connecting terminals which are provided for electrically contacting the respective power busbar,

wherein the terminal-receiving regions of the contact protection modules each comprise contacting slots, which are arranged in parallel and offer protection against direct contact, for electrically contacting the power busbars by means of the connecting terminals,

wherein the contacting slots of the contact protection modules are formed in such a manner that they provide a uniform division of all mutually latched contact protection modules.
