Abstract

An exemplary voltage sensor device includes at least one high voltage segment and at least one low voltage impedance element. In order to enhance the power dissipation due to impedances spread inside of the device body, the sensor device can be adapted or extended such that at least one high voltage segment, and at least one low voltage impedance element are arranged on an elongated insulating support with adaptive complementary mechanical and electrical interconnection elements on at least one end of the support element. The mechanical and electrical interconnection elements provide a manner of interconnecting at least two elongated insulating supports together in a pivotable way.

First claim

What is claimed is:

1. A voltage sensor device, comprising:
a first segment and a second segment, each segment comprising an elongated insulating support with a connection hole through which the first and second segments are fixed to each other, the first and second segments being pivotal relative to each other around the connection holes;
the first and second segments each comprising an impedance element, the impedance element of each first and second segment being flat and arranged on one or both sides of the respective elongated insulating support without being coiled around the respective elongated insulating support; and
the elongated insulating support of the first segment having a conductive element with a hole and an arc-shaped opening, one end of the impedance element of the first segment being electrically connected to the conductive element through the hole, and one end of the impedance element of the second segment being electrically connected to the conductive element through the arc-shaped opening.

2. The voltage sensor device according to claim 1 , wherein the first and second segments are low voltage impedance elements arranged with a relative position under an angle which is smaller than 180°.

3. The voltage sensor device according to claim 1 , wherein a resulting value of low voltage impedance can be built up together from at least one standard impedance value of the first and second segments.

4. The voltage sensor device according to claim 1 , wherein the impedance elements are either resistive elements or capacitive elements or combination of both.

5. The voltage sensor device according to claim 1 , wherein the first and second segments comprise low voltage impedance elements that are connected with the at least one high voltage segment in parallel and/or in series based on a specified impedance value.

6. The voltage sensor device according to claim 1 , further comprising a plurality of impedance elements connected to the first or second segment that are assembled into at least one fixed configuration having with at least one fixed dimension and at least one fixed angle between elements, the at least one fixed configuration having a main fixed insulating support.

7. The voltage sensor device according to claim 6 , wherein the main fixed insulating support mechanically reduces the number of elements by breaking or cutting off the unused part of said support.
