Description
Technical field
The utility model is related to a kind of Rogowski coil, more particularly, to one kind can arbitrarily adjusting ring footpath to reach optimum measurement
The high-precision rogowski coil of state, belongs to Rogowski coil technical field.
Background technology
At present, it is frequently utilized that Rogowski coil carries out signal measurement, but is due to testee end face girth 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,
Traditional flexible Rogowski coil is caused not to be fixed easily, easily slide, so as to influence the measuring accuracy of Rogowski coil after installing；And work as quilt
When surveying object under the narrower environment in space, Traditional flexible Rogowski coil is due to size reason, and installation personnel can not be effective
Install or installation difficulty, cause constructional difficulties；In addition, Traditional flexible Rogowski coil is because the presence of plug, it is impossible to formed
The coil of closure --- as shown in figure 3, so as to influence its measurement accuracy, this is the universal problem in present Rogowski coil field.
The content of the invention
The purpose of this utility model is to overcome that above-mentioned not enough there is provided a kind of simple in construction, easy to use and measurement accuracy
High adjustable type high-precision rogowski coil.
What the purpose of this utility model was realized in：
A kind of adjustable type high-precision rogowski coil, the Rogowski coil includes fixed chuck, and the fixed chuck is included
There are lower fixture and upper holder, the lower fixture is fixedly connected in coil body, and the upper holder includes arc
Shape part and arc lower part, the arc lower part are fixedly connected on lower fixture, upper the arcuate member right-hand member and arc lower part
Right-hand member is hinged, and is provided with fixture block, the left end outer wall of the upper arcuate member and is provided with the left end outer wall of the arc lower part
The bayonet socket inserted for fixture block is provided with clamping piece, the clamping piece.
On a kind of adjustable type high-precision rogowski coil of the utility model, the inwall of upper the arcuate member right-hand member and arc lower part
Axially arranged there is a plurality of tooth engaged along its.
A kind of adjustable type high-precision rogowski coil of the utility model, the surface of the fixture block is inclined-plane, the clamping piece with
The medial surface that fixture block is in contact is inclined-plane.
Compared with prior art, the beneficial effects of the utility model are：
The utility model causes the coil that Rogowski coil body formation one is completely closed using fixed chuck design structure, from
And ensure its precision；Meanwhile, the utility model uses the design structure that loop length can be adjusted so that coil can become to appoint
The length that meaning needs, so as to be effectively fixed on testee, is difficult to slide, so as to ensure the precision of test.
Brief description of the drawings
Fig. 1 is a kind of structural representation of adjustable type high-precision rogowski coil of the utility model.
Fig. 2 is a kind of close-up schematic view of adjustable type high-precision rogowski coil of the utility model.
Fig. 3 is the structural representation of conventional Rogowski coil.
Wherein：
Testee 101；
Coil body 1, fixed chuck 2；

Embodiment
Referring to Fig. 1 and Fig. 2, a kind of adjustable type high-precision rogowski coil that the utility model is related to, the Rogowski coil bag
Containing fixed chuck 2, the fixed chuck 2 includes lower fixture 2.1 and upper holder 2.2, and the lower fixture 2.1 is fixed
It is connected in coil body 1, the upper holder 2.2 includes arcuate member 2.2.1 and arc lower part 2.2.2, the lower arc
Shape part 2.2.2 is fixedly connected on lower fixture 2.1, the right-hand member phase of upper arcuate member 2.2.1 right-hand members and arc lower the part 2.2.2
Be hinged, and on upper arcuate member 2.2.1 right-hand members and arc lower part 2.2.2 inwall along its it is axially arranged have a plurality of tooth engaged 2.2.3,
It is provided with fixture block 2.3, the left end outer wall of the upper arcuate member 2.2.1 and sets on the left end outer wall of the arc lower part 2.2.2
There is the bayonet socket 2.4.1 for being provided with and being inserted for fixture block 2.3 on clamping piece 2.4, the clamping piece 2.4；
It is preferred that, the surface of the fixture block 2.3 is inclined-plane, and the clamping piece 2.4 is with the medial surface that fixture block 2.3 is in contact
Inclined-plane, so that smooth when ensureing clamping；
In use, one end of coil body 1 is mutually fixedly connected with lower fixture 2.1, and signal lead-out wire is via lower solid
Determine part 2.1 to draw, the other end of coil body 1 is bypassed by the tooth engaged 2.2.3 pressings by upper holder 2.2 after testee 101,
And locking by fixture block 2.3 and bayonet socket 2.4.1；So that the one complete loop configuration of formation of coil body 1, it is ensured that
Measurement accuracy；During unblock, clamping piece 2. is pulled so that fixture block 2.3 departs from bayonet socket 2.4.1, you can easily remove coil body 1.
In addition：It should be noted that above-mentioned embodiment is only a prioritization scheme of this patent, the skill of this area
Any change or improvement that art personnel are done according to above-mentioned design, within the protection domain of this patent.
