Abstract

The invention relates to a space-saving isolating arrester, having
for at least two electronic components (EB 1 , EB 2 ) to be monitored, with the electronic components to be monitored being fastened to a carrier (P) using a thermally softenable fixing means, with an energy accumulator (D 1 ,D 2 ) being arranged on each of the electronic components which—when a thermally softenable fixing means softens—displaces the associated electronic component substantially parallel to the carrier (P), thereby disconnecting the associated electronic component, and also having a mechanically displaceable display means (ANZ), with the mechanically displaceable display means indicating that one or more of the electronic components to be monitored has been disconnected, and with the mechanically displaceable display means (ANZ) being displaced by a disconnecting electronic component.

First claim

What is claimed is:

1. A space-saving isolating arrester, comprising:
at least two electronic components
fastened to a carrier using a thermally softenable fixing means;
an energy accumulator arranged on each of the at least two electronic components which, when the thermally softenable fixing means softens, displaces an associated electronic component of the at least two electronic components substantially parallel to the carrier, thereby disconnecting the associated electronic component; and
a mechanically displaceable display means to indicate that one or more of the at least two electronic components has been disconnected, wherein the mechanically displaceable display means is displaced by a disconnecting electronic component.

2. The device as set forth in claim 1 , wherein the mechanically displaceable display means has a fixing device for fixing the mechanically displaceable display means in a starting position.

3. The device as set forth in claim 1 , further comprising:
a fixing device for fixing a disconnected electronic component in a disconnected state.

4. The device as set forth in claim 2 , wherein the fixing device and the mechanically displaceable display means are integrally formed with the fixing device being flexible relative to the mechanically displaceable display means.

5. The device as set forth in claim 1 , further comprising:
a housing with a first guide means being provided in the housing in order to guide the mechanical display means.

6. The device as set forth in claim 5 , wherein
a second guide means is provided in the housing in order to guide an electronic component to be disconnected.

7. The device as set forth in claim 1 , wherein the energy accumulators are springs.

8. The device as set forth in claim 1 , wherein the mechanically displaceable display means makes a change in color and/or a change in transmission available.

9. The device as set forth in claim 1 , further comprising:
devices for mounting on a supporting rail.

10. The device as set forth in claim 1 , wherein the at least two electronic components are selected from the group which includes varistors, TVS diodes, or gas-filled overvoltage arresters.

11. The device as set forth in claim 1 , wherein the thermally softenable fixing means has a solder and/or an adhesive.

12. The device as set forth in claim 5 , wherein the housing and/or the mechanically displaceable display means is made of a plastic material.

13. A system, comprising:
a plurality of space-saving isolating arresters arranged next to one another, each space-saving isolating arrester including:
at least two electronic components fastened to a carrier using a thermally softenable fixing means;
an energy accumulator arranged on each of the at least two electronic components which, when the thermally softenable fixing means softens, displaces an associated electronic component of the at least two electronic components substantially parallel to the carrier, thereby disconnecting the associated electronic component; and
a mechanically displaceable display means to indicate that one or more of the at least two electronic components has been disconnected, wherein the mechanically displaceable display means is displaced by a disconnecting electronic component, wherein the plurality of space-saving isolating arresters provide a common fault reporting in the normal direction toward a respective carrier.

14. The system as set forth in claim 13 , wherein each mechanically displaceable display means has a fixing device for fixing the mechanically displaceable display means in a starting position.

15. The system as set forth in claim 13 , wherein each space-saving isolating arrester further comprises:
a fixing device for fixing a disconnected electronic component in a disconnected state.

16. The system as set forth in claim 14 , wherein the fixing device and the mechanically displaceable display means for each space-saving isolating arrester are integrally formed with the fixing device being flexible relative to the mechanically displaceable display means.

17. The system as set forth in claim 13 , wherein each space-saving isolating arrester further comprises:
a housing with a first guide means being provided in the housing in order to guide the mechanical display means.

18. The system as set forth in claim 17 , wherein a second guide means is provided in each housing in order to guide an electronic component to be disconnected.

19. The system as set forth in claim 13 , wherein the energy accumulators are springs.

20. The system as set forth in claim 13 , wherein the at least two electronic components are selected from the group which includes varistors, TVS diodes, or gas-filled overvoltage arresters.
