Adjustable high precision Rogowski coil

Abstract

The invention discloses an adjustable high-accuracy Rogowski coil. The Rogowski coil comprises a fixing chuck (2), the fixing chuck (2) comprises a lower fixing piece (2.1) and an upper clamping piece (2.2), the lower fixing piece (2.1) is fixedly connected onto a coil body (1), the upper clamping piece (2.2) comprises an upper arc piece (2.2.1) and a lower arc piece (2.2.2), the lower arc piece (2.2.2) is fixedly connected onto the lower fixing piece (2.1), the right end of the upper arc piece (2.2.1) is hinged to the right end of the lower arc piece (2.2.2), a clamping block (2.3) is arranged on the outer wall at the left end of the lower arc piece (2.2.2), a clamping connection sheet (2.4) is arranged on the outer wall at the left end of the upper arc piece (2.2.1), and the clamping connection sheet (2.4) is provided with a clamping opening (2.4.1) where the clamping block (2.3) is inserted. The adjustable high-accuracy Rogowski coil is simple in structure, convenient in use and high in measurement accuracy.

Description

technical field [0001] The invention relates to a Rogowski coil, in particular to a high-precision Rogowski coil whose coil diameter can be adjusted at will to achieve the best measurement state, and belongs to the technical field of Rogowski coils. Background technique [0002] At present, Rogowski coils are often used for signal measurement, but because the circumference of the measured object’s end face does not match well with the flexible Rogowski coil, and even the end face of the measured object is an irregular object, it is difficult to match it with the flexible Rogowski coil, resulting in conventional flexible Rogowski coils. After the Rogowski coil is installed, it is not easy to fix and slide, which affects the test accuracy of the Rogowski coil; and when the measured object is in a relatively cramped environment, due to the size of the conventional flexible Rogowski coil, the installer cannot effectively install or the installation is difficult, resulting in The...

[0002] At present, Rogowski coils are often used for signal measurement, but because the circumference of the measured object’s end face does not match well with the flexible Rogowski coil, and even the end face of the measured object is an irregular object, it is difficult to match it with the flexible Rogowski coil, resulting in conventional flexible Rogowski coils. After the Rogowski coil is installed, it is not easy to fix and slide, which affects the test accuracy of the Rogowski coil; and when the measured object is in a relatively cramped environment, due to the size of the conventional flexible Rogowski coil, the installer cannot effectively install or the installation is difficult, resulting in The construction is difficult; in addition, the conventional flexible Rogowski coil cannot form a closed coil because of the existence of the plug—such as image 3 As shown, thus affecting its measurement accuracy, this is a common problem in the field of Rogowski coils
