Description

Novel flexible Rogowski coil

Technical Field

The utility model belongs to the technical field of the luo shi coil, concretely relates to novel flexible luo shi coil.

Background

The Rogowski coil is a kind of AC current sensor, and is a hollow ring coil, which has two kinds of flexibility and rigidity, and can be directly covered on the measured conductor to measure AC current.

The flexible Rogowski coil in the market at present adopts a copper foil to wrap after a layer of insulating tape is wrapped outside a coil so as to achieve the purpose of anti-disturbance, the method is troublesome in operation and low in efficiency, a product needs to be looped into a circle to cover a cable during installation, and at the moment, because the copper foil is non-contractible, the outer ring copper foil is easy to stretch and break, the anti-interference performance of the product is unstable, and therefore the novel flexible Rogowski coil is provided.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a novel flexible luo shi coil to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a novel flexible rogowski coil, includes the sinle silk, the outside of sinle silk is encircleed to open and is equipped with a plurality of draw-in grooves, the outside winding of sinle silk has the enameled wire, the enameled wire all sets up inside the draw-in groove, the sinle silk is equipped with the pyrocondensation pipe at the outside activity cover of enameled wire, the outside of pyrocondensation pipe is provided with the shielding layer, the material of shielding layer is the copper shield net, the inside fixed reinforced column that is provided with of sinle silk, the reinforced column runs through the positive center.

Preferably, the material of sinle silk is silica gel.

Preferably, the shielding layer is a telescopic woven mesh composed of copper wires.

Preferably, the size of the clamping groove is meshed with the enameled wire.

Preferably, the reinforcing column is cross-shaped.

Preferably, the material of the reinforcing column is rubber.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses an it is equipped with the draw-in groove to encircle in the outside of sinle silk, through with the enameled wire setting inside the draw-in groove, can guarantee the stability of enameled wire installation, can effectually prevent that the enameled wire from taking place the displacement at subsequent work, establishes one deck pyrocondensation pipe through the outside cover at the enameled wire, and is provided with the shielding layer through the outside at the pyrocondensation pipe, and the shielding layer that uses now is simplified for copper shield net process, and lifting efficiency, shielding property is stable.
