Problems solved by technology

This introduces the need for additional fastening material and special assembly tooling applications, which negatively impacts manufacturing time and production costs
Another disadvantage of the above-mentioned solution, especially in the case of using a tightening strap, is that the required perpendicularity with respect to the main conductor and the centering of the sensing device around the main conductor cannot be ensured, which results in the sensing accuracy of the measuring device reduce

Embodiment Construction

[0024] According to all embodiments, the invention is described as follows: The fastening element 3 of special structure ensures that the simple sensing device 2 is fixed in the most suitable position on the main conductor 1 and thus ensures a stable current and / or voltage with high precision signal measurements such as figure 1 shown in . In the case where a larger contact force value is required between the fastening element 3 directly and the main conductor 1 or between the fastening element and the electrical device including the main conductor 1, such as figure 1 and figure 2 As shown in , the fastening element 3 is designed to allow the use of a tightening strap 4 which is passed through a hole element or eyelet element 5 and / or is arranged on the surface of the fastening element 3 .

[0025] exist figure 1 , the first section 3 ′ is provided with an engagement pin 10 which must be inserted into a hole in the housing of the sensor 2 . The first segment 3' is oriente...

Abstract

The invention relates to fastening means or device for fastening a voltage and / or current sensor on a electrical conductor, according to the preamble of claim 1. In order to enhance fasting means or device for fasting voltage sensors in such a way, that the fixation is accurate and reproductive as well, the invention is, that the fastening device comprise of a number of at least two fastening elements (3), each with a dowel pin clip, or a clamp at a first section (3') of the fastening element, and a support element at a second section (3") of the fastening element, so that the dowel pin clip (10) or the clamp has to be inserted into, or clamped on the housing of the sensor (2) at the first section (3'), and the support element at the second section (3") has to be fixed on the electrical conductor (1).

Description

technical field [0001] The invention relates to a fastening device for current sensors and / or voltage sensors used in low-medium voltage and high voltage according to the preamble of claim 1 . Background technique [0002] The desired positioning of the ring-core low, medium or high current and / or voltage sensing device is dictated by the sensing device design and its size and by including the current and / or voltage signal source to be measured (i.e., the sensing device Body) construction of electrical devices. Tightening straps or another supplementary fastening material, such as bolts, adhesives, etc., are used to fasten the sensing device to the electrical device including the main conductor. This introduces the need for additional fastening material and application of special assembly tooling, which negatively affects manufacturing time and production costs. Another disadvantage of the above-mentioned solution, especially in the case of using a tightening strap, is tha...
