Description

Technical Field

[0001] The utility model relates to the technical field of current transformer coils, in particular to a flexible strip-shaped current transformer coil. Background Art

[0002] The structure of the current transformer is that the coil is wound on a closed annular magnetic core. The existing current transformers can be roughly divided into fixed type and open-close type. The structure of the open-close current transformer is divided into two cases. One is that the coil is wound on a closed magnetic core and then cut and assembled into an annular closed structure. The other is that the coil is wound on a cut magnetic core and then assembled into an annular closed structure.

[0003] However, the external structures of existing current transformers are fixed and cannot be changed, which greatly restricts their installation and use scenarios and results in poor versatility of the products. Utility Model Content

[0004] The purpose of the utility model is to provide a flexible strip current transformer coil to solve the problem that the external structure of the current transformer in the prior art is fixed and cannot be changed, which leads to great restrictions on its installation and use scenarios and poor product versatility.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a flexible strip-shaped current transformer coil, comprising a primary conductor, a flexible strip-shaped support portion is provided outside the primary conductor, the flexible strip-shaped support portion is magnetic, the flexible strip-shaped support portion forms a closed magnetic field loop, and an enameled wire is wound on the flexible strip-shaped support portion.

[0006] As a preferred technical solution of the utility model: the flexible strip-shaped support portion is a flexible strip-shaped soft magnetic material core.

[0007] As a preferred technical solution of the utility model: two sides of the flexible band-shaped soft magnetic material core are connected and closed by a fixing clip.

[0008] By adopting the above technical scheme, the beneficial effect of the utility model is as follows: the utility model changes the structural form of the current current transformer coil and utilizes a flexible strip-shaped soft magnetic material core to make the current transformer coil have a flexible and variable structural shape, so that it is no longer restricted by the appearance, thereby greatly improving the applicability and ease of installation of the product.

[0012] The embodiments of the utility model are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the utility model, and cannot be understood as limiting the utility model. In the description of the utility model, it should be understood that the orientation or position relationship indicated by the terms "upper", "lower", "front", "upper surface", etc. is based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the utility model. In the utility model, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral body; it can be a mechanical connection, an electrical connection, or can communicate with each other; it can be directly connected, or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0013] See also Figure 1-2 The utility model provides an embodiment: a flexible strip-shaped current transformer coil, including a primary conductor 1, a flexible strip-shaped support portion 2 is provided outside the primary conductor 1, the flexible strip-shaped support portion 2 is magnetic, the flexible strip-shaped support portion 2 forms a closed magnetic field loop, and an enameled wire 3 is wound on the flexible strip-shaped support portion 2.

[0014] The flexible strip-shaped support portion 2 is a flexible strip-shaped soft magnetic material core, and two sides of the flexible strip-shaped soft magnetic material core are connected and closed by a fixing clip 4 .

[0015] The enameled wire 3 is wound on the flexible strip-shaped soft magnetic material core, and the flexible strip-shaped soft magnetic material cores at both ends are connected by the surface of the fixing clip 4 to form a closed magnetic field loop. Such a coil no longer has to be fixed, but has the characteristics of flexibility and deformability, which improves the applicability and installation convenience of the product.

[0016] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
