Abstract

A test system ( 10 ) for testing an electric device ( 30 ), in particular a high-voltage device, has a portable main device ( 100 ) with a housing ( 140 ), an electric connection assembly ( 120, 121 ) and a mechanical connection assembly ( 145 ) and has a portable additional device ( 200, 300 ) with a separate housing ( 240, 340 ), an electric connection assembly ( 220, 320 ) and a mechanical connection assembly ( 245 ). The main device ( 100 ) can be mechanically connected to the additional device ( 200, 300 ) in a releasable manner by coupling the mechanical connection assemblies ( 145, 245 ) to form a structural unit, wherein the main device ( 100 ) can be electrically connected to the additional device ( 200, 300 ) via the first electric connection assemblies ( 120, 121, 220, 320 ).

First claim

The invention claimed is:

1. A test system for testing an electric device, comprising:
a portable main device with a first housing and a first mechanical connection assembly disposed on the first housing and a first electric connection assembly disposed on the first housing, and
a portable additional device, separate from the portable main device, with a second housing and a second mechanical connection assembly disposed on the second housing and a second electric connection assembly disposed on the second housing,
wherein the portable main device can be mechanically connected to the portable additional device in a releasable manner by coupling the first mechanical connection assembly to the second mechanical connection assembly to form a structural unit,
wherein the portable main device can be electrically connected to the portable additional device via the first electric connection assembly and the second electric connection assembly,
wherein the portable main device has a power-amplifying device for generating a power signal which is to be transmitted to the portable additional device via the first electric connection assembly and the second electric connection assembly,
wherein the portable additional device has a test signal apparatus for generating a test signal, which is to be output to the electric device, on the basis of the power signal of the portable main device, and
wherein the portable main device has a measuring device for measuring a measurement variable of the electric device as a test response to the test signal of the portable additional device.

2. The test system according to claim 1 , wherein the portable main device and the portable additional device can be connected in a releasable manner at contact surfaces of the portable main device and of the portable additional device to form the structural unit, wherein dimensions of the contact surface of the portable main device substantially correspond to dimensions of the contact surface of the portable additional device.

3. The test system according to claim 1 , wherein the first mechanical connection assembly and the second mechanical connection assembly are formed such that the portable main device can be connected to the portable additional device in a force-fitting, form-fitting and/or friction-fitting manner to form the structural unit.

4. The test system according to claim 1 , wherein the first housing of the portable main device and the second housing of the portable additional device have substantially the same dimensions.

5. The test system according to claim 1 , wherein the portable additional device has a transformer as the test signal apparatus and is arranged such that the portable additional device converts the power signal of the portable main device into the test signal by means of the transformer such that the power signal and the test signal are electrically isolated and the test signal has a voltage of at least 1 KV.

6. The test system according to claim 1 , wherein the portable additional device is configured such that the portable additional device records the test response to the test signal and transmits it to the measuring device of the portable main device.

7. The test system according to claim 1 , wherein the portable main device is configured such that the portable main device records the test response to the test signal of the portable additional device and forwards it to the measuring device of the portable main device.

8. The test system according to claim 1 , wherein the portable main device has a controlling device for controlling the power-amplifying device and the measuring device.

9. The test system according to claim 8 , wherein the controlling device is configured such that, via an electric connection between the first electric connection assembly and the second electric connection assembly, it triggers the test signal apparatus of the portable additional device to generate the test signal to be output to the electric device.

10. The test system according to claim 8 , wherein the controlling device is configured such that, via an electric connection between the first electric connection assembly and the second electric connection assembly, it controls the testing of the electric device through the test signal of the portable additional device.

11. The test system according to claim 1 , comprising a hybrid cable, which is arranged to electrically connect the portable main device to the portable additional device via the first electric connection assembly and the second electric connection assembly and configured to simultaneously transmit both the power signal and a data signal.

12. The test system according to claim 11 , wherein the hybrid cable is additionally configured to simultaneously transmit a safety signal.

13. The test system according to claim 1 , wherein the portable main device has an energy supply device and is configured to supply energy to the portable additional device by means of the energy supply device.

14. The test system according to claim 1 , wherein both the portable main device and the portable additional device are formed as an independent measuring device.

15. The test system according to claim 1 , wherein it is configured to test an electric high-voltage device.

16. A test system for testing an electric device, comprising:
a portable main device with a first housing and a first mechanical connection assembly disposed on the first housing and a first electric connection assembly disposed on the first housing,
a portable additional device, separate from the portable main device, with a second housing and a second mechanical connection assembly disposed on the second housing and a second electric connection assembly disposed on the second housing, and
a hybrid cable, which is arranged to electrically connect the portable main device to the portable additional device via the first electric connection assembly and the second electric connection assembly and configured to simultaneously transmit both a power signal and a data signal,
wherein the portable main device can be mechanically connected to the portable additional device in a releasable manner by coupling the first mechanical connection assembly to the second mechanical connection assembly to form a structural unit,
wherein the portable main device can be electrically connected to the portable additional device via the first electric connection assembly and the second electric connection assembly, and
wherein the hybrid cable comprises:
an electric connecting element disposed at one end for the portable main device for releasable connection to the first electric connection assembly of the portable main device,
an electric connecting element arranged at a different end for the portable additional device for releasable connection to the second electric connection assembly of the portable additional device,
at least one wire for transmitting the power signal between the portable main device and the portable additional device;
at least one wire for data communication between the portable main device and the portable additional device; and
