High-precision rogowski coil, belong to Rogowski coil technical field.
Background technique
Currently, it is frequently utilized that Rogowski coil carries out signal measurement, but due to testee end face perimeter and flexible Luo
Coil matching degree is bad or even testee end face is irregularly shaped object, so that it is difficult to match with flexible Luo-coil,
It is not fixed easily after causing conventional flexible Rogowski coil to be installed, easily slides, to influence the measuring accuracy of Rogowski coil；And work as quilt
When surveying object under the narrower environment in space, for conventional flexible Rogowski coil due to size, installation personnel can not be effective
Installation is difficult to install, leads to constructional difficulties；In addition, conventional flexible Rogowski coil can not be formed because of the presence of plug
The coil of closure --- as shown in figure 3, to influence its measurement accuracy, this is the universal problem in present Rogowski coil field.
Summary of the invention
The purpose of the present invention is to overcome the above shortcomings and to provide a kind of structures, and simple, easy to use and measurement accuracy is high
Adjustable type high-precision rogowski coil.
The object of the present invention is achieved like this:
A kind of adjustable type high-precision rogowski coil, the Rogowski coil include fixed chuck, and the fixed chuck includes
There are lower fixing piece and upper clamping piece, the lower fixing piece is fixedly connected in coil body, and the upper clamping piece includes upper arc
Shape part and arc lower part, the arc lower part are fixedly connected on lower fixing piece, the upper arc-shaped workpiece right end and arc lower part
Right end is hinged, and fixture block is provided on the left end outer wall of the arc lower part, is provided on the left end outer wall of the upper arc-shaped workpiece
It is clamped piece, the clamping on piece is provided with the bayonet for fixture block insertion.
Along it on the inner wall of a kind of adjustable type high-precision rogowski coil of the present invention, the upper arc-shaped workpiece right end and arc lower part
Axially it is provided with a plurality of tooth engaged.
A kind of adjustable type high-precision rogowski coil of the present invention, the surface of the fixture block are inclined-plane, the clamping piece and fixture block
The medial surface being in contact is inclined-plane.
Compared with prior art, the beneficial effects of the present invention are:
The present invention makes Rogowski coil ontology form a coil being completely closed using fixed chuck design structure, to protect
Demonstrate,prove its precision；Meanwhile the design structure that the present invention is adjustable using coil length, allow coil to become any needs
Length, it is difficult to slide so as to be effectively fixed on testee, to guarantee the precision of test.
