Abstract
The utility model discloses one kind, and flat Rogowski coil is adjusted, and the Rogowski coil includes the coil base and fastening structure that flat conducting wire is constituted；The coil base width is greater than thickness, and surface is coated with insulating layer；The fastening structure includes connector sleeve and locking member, and Rogowski coil one end is connect with connector sleeve；The locking member is connect with connector sleeve.Rogowski coil structure disclosed by the utility model is simple, easy for installation, difficult to slide, simultaneously because coil base be it is flat, section is big, so that output signal is larger, is easy to measure.
Description
Technical field
The utility model relates to a kind of Rogowski coils, and in particular to a kind of adjustable pitch circle diameter is to reach optimum measurement state
Flat Rogowski coil.
Background technique
In the prior art, Rogowski coil is frequently used for carrying out signal measurement, but due to testee outer perimeter and flexibility
Rogowski coil matching degree is bad or even testee surface is irregularly shaped object, so as to cause the installation of conventional flexible Rogowski coil
Easily sliding afterwards.In addition conventional Rogowski coil is generally single circular coil, and measuring signal is smaller, and error is larger.
Utility model content
The purpose of this utility model is that overcome defect existing in the prior art, provide that a kind of structure is simple, installation side
Just, difficult to slide, be easy to measure is adjusted flat Rogowski coil.
To achieve the above object, the technical solution of the utility model is to provide one kind flat Rogowski coil is adjusted, described
Rogowski coil includes the coil base and fastening structure that flat conducting wire is constituted；The coil base width is greater than thickness, table
Bread is covered with insulating layer；The fastening structure includes connector sleeve and locking member, and the connector sleeve outer wall has through-hole, Rogowski coil one
End is connect with connector sleeve；The locking member passes through through-hole on connector sleeve and connect with connector sleeve.
When Rogowski coil need to measure object outer perimeter it is not of uniform size when, preferred technical solution is the connector sleeve
For both ends open connector sleeve.Connector sleeve is both ends open, and one end of Rogowski coil is connect with connector sleeve, and it is another to hold Rogowski coil
End is inserted through connector sleeve after testee, tightens locking member, Rogowski coil is fixed about testee, is not easy to slide
It falls.
Using Rogowski coil in measurement, pull, lock wire circle for convenience surrounds testee, preferred technical side
Case is that the connector sleeve side is equipped with non-slip groove or fin.
The coil base of Rogowski coil be it is flat, preferred technical solution is, the connector sleeve is rectangular.Flat line
Cycle basis body can be fixedly connected with the one of plane of rectangular connector sleeve, and the plane of flat coil base and rectangular tube is closely pasted
It closes, connects stronger.
Preferred technical solution is that outer wall has tapped through hole on the connector sleeve outer wall, and locking member is bolt, passes through connection
Set outer wall upper tapped through hole is connect with connector sleeve.External screw thread and through-hole internal screw thread are fitted close on locking member, and locking member is not easy pine
It is dynamic.
Preferably technical solution is that the locking member is self-locking inclined-plane.The locking member facilitates right-hand man while operating locking
Coil, and switching performance is excellent.
When testee outer surface is irregular, when measuring using Rogowski coil, need repeatedly to bend coil, or measurement ring
Border temperature is relatively high, and preferred technical solution is that the insulating layer is silicone insulation layer.Silicone insulation layer good electric property, it is soft
It is soft more preferable, and can better high-temperature-resistant high-pressure-resistant.
Preferred technical side is that the connector sleeve is adopted made of plastic.It adopts and connector sleeve is made of plastic, simple process, at
This is cheap.
The advantages of the utility model and beneficial effect are：The coil base that is mainly characterized by of the Rogowski coil is flat
Shape, it is different with the circle of general Rogowski coil, increases cross-sectional area, so that output signal is larger, is easy to measure, and energy
Reduce measurement error.Secondly, length of the Rogowski coil using the fastening structure regulating winding that can twitch tightening, so that coil can
Length is needed to become any, it is difficult to slide so as to be effectively fixed on testee.
Detailed description of the invention
Fig. 1 is the structural schematic diagram that flat Rogowski coil is adjusted in the utility model；
Fig. 2 is the self-locking inclined-plane bottom view of the utility model；
In figure：1, flatwise coil matrix；2, connector sleeve；3, locking member；4, lock tongue；5, inclined-plane；6, pressing spring is pressed；7, horizontal
Bar.
Specific embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is further described.Implement below
Example is only used for clearly illustrating the technical solution of the utility model, and cannot be used as a limitation the protection model of limitation the utility model
It encloses.
Embodiment 1
As shown in Figure 1, the utility model is that flat Rogowski coil is adjusted in one kind, the Rogowski coil includes flat
