Abstract

A device for the automatic control of joints 5 in electrical high voltage lines is disclosed. It comprises a first support 1, a first wheel 2, for lying on a line 4, a driver for driving the first wheel 2, at least one second wheel 3 for lying on the line 4, a measurement unit 11, in contact with a device for measurement of physical data at the joint. The device includes at least one pointed element 7,8,9 for electrical contact with the line 4. The device is especially characterized in that at least one wheel 2,3 is provided electrically connected to the measurement unit.

Claims

1. A device for the automatic control of joints in electrical high voltage lines, comprising:

a first support;

a first wheel for lying on the line;

a driving means for driving of said first wheel;

at least one second wheel, for lying on said line;

a measurement unit in contact with means for the measurement of physical data at said joint, said measurement unit comprising at least one pointed element for electrical contact with the line,

wherein at least one of said first and second wheels is provided electrically connected to said measurement unit.

2. The device according to claim 1, wherein the means for measurement of physical data in the form of one pointed element also comprise at least one of said first and second wheels.

3. The device according to claim 2, further comprising:

a retainer, journalled in the support so as to be swung up below the line to increase pressure of at least one of the first wheel and second wheel against the line so as to improve electrical contact between the wheel and the line.

4. The device according to claim 3, further comprising:

measurement indicators for measurement of the position of the device in relationship to the actual joint.

5. The device according to claim 4, wherein the measurement indicator comprises a laser distance gauge.

6. The device according to claim 2, further comprising:

measurement indicators for measurement of the position of the device in relationship to the actual joint.

7. The device according to claim 6, wherein the measurement indicator comprises a laser distance gauge.

8. The device according to claim 1, further comprising:

a retainer, journalled in the support so as to be swung up below the line to increase pressure of the wheel against the line.

9. The device according to claim 8, further comprising:

measurement indicators for measurement of the position of the device in relationship to the actual joint.

10. The device according to claim 9, wherein the measurement indicator comprises a laser distance gauge.

11. The device according to claim 1, further comprising:

measurement indicators for measurement of the position of the device in relationship to the actual joint.

12. The device according to claim 11, wherein the measurement indicator comprises a laser distance gauge.
