Abstract
The utility model discloses a reactor with shielding layer, including hollow coil and setting at hollow coil outlying shielding layer, hollow coil's quantity is a plurality of, and a plurality of hollow coil set up side by side, are equipped with the parting bead between two adjacent hollow coil, and the most avris hollow coil of a plurality of hollow coils passes through support and shielding layer fixed connection. The support makes have the clearance between the most avris hollow coil and the shielding layer, and the parting bead makes have the clearance between every two adjacent hollow coil, and the heat dissipation of a plurality of hollow coil of being convenient for is given birth to in the existence in clearance. The shield layer not only reduces the magnetic field around the reactor, but also has the effect of increasing the inductance around the reactor.
Description
Technical Field
The utility model relates to a reactor, concretely relates to reactor with shielding layer.
Background
The periphery of the reactor is provided with a shielding layer, which functions to reduce the magnetic field around the reactor (e.g., inductor). Customers require limiting the maximum magnetic flux at different distances from the reactor.
SUMMERY OF THE UTILITY MODEL
The utility model solves the technical problem that: an air-core reactor with a shielding layer is designed.
In order to solve the technical problem, the utility model provides a following technical scheme: reactor with shielding layer, including hollow coil and setting at hollow coil outlying shielding layer, hollow coil's quantity is a plurality of, and a plurality of hollow coil set up side by side, is equipped with the parting bead between two adjacent hollow coil, and the hollow coil of a plurality of hollow coil most avris passes through support and shielding layer fixed connection.
The support makes have the clearance between the most avris hollow coil and the shielding layer, and the parting bead makes have the clearance between every two adjacent hollow coil, and the heat dissipation of a plurality of hollow coil of being convenient for is given birth to in the existence in clearance.
The shield layer not only reduces the magnetic field around the reactor, but also has the effect of increasing the inductance around the reactor. If the thickness of the shield layer is increased, the total inductance of the reactor will increase. This is because the magnetic energy in the entire reactor will increase and therefore the inductance will also increase.
The biggest magnetic flux and the inductance of specific position department all are the requirement of customer to the reactor around the reactor, the shielding layer can satisfy this kind of requirement.

Detailed Description
With reference to fig. 2 and 4, the reactor with the shielding layer comprises a plurality of hollow coils 10 and a shielding layer 20 arranged on the periphery of the hollow coils, wherein the hollow coils are arranged in parallel, a plurality of parting beads 30 are arranged between every two adjacent hollow coils, and the most lateral hollow coils of the plurality of hollow coils are fixedly connected with the shielding layer through a support.
The thickness of the shield layer 20 is adjusted so that the maximum magnetic flux at a specific position from the reactor is limited within a specific value. At the same time, the shield layer 20 can increase the inductance of the reactor. For example, if a customer requests the inductance of the reactor to reach 3mH, the air core inductance can be designed to be about 2.4mH, and then when the shielding layer is added, the inductance will increase by 0.6mH to meet the use requirement.
As shown in fig. 4, the bracket alternatively includes a side plate 41, a supporting block 42 and an edge strip 43, the side plate is fixedly connected to the shielding layer 20, the supporting block is fixedly connected to the side plate, the edge strip is fixedly connected to the supporting block, and the edge strip is fixedly connected to the most lateral coil of the plurality of hollow coils. The number of the side plates is two, namely a left side plate and a right side plate, the left side plate is fixedly connected with the left side wall in the shielding layer 20, and the right side plate is fixedly connected with the right side wall in the shielding layer. Accordingly, the number of the supporting blocks 42 is two, and is a left supporting block connected to the left side plate and a right supporting block connected to the right side plate. Accordingly, the number of the edge bars 43 is two, i.e., a left edge bar and a right edge bar, the left edge bar is connected to the left support block, and the right edge bar is connected to the right support block. The left side strip is connected with the leftmost hollow coil of the plurality of hollow coils, and the right side strip is connected with the rightmost hollow coil of the plurality of hollow coils.
Referring to fig. 3 and 4, as an alternative, the side plates 41, the supporting blocks 42, the edge strips 43 and the spacer bars 30 are all made of wood, the side plates are connected with the shielding layer 20 through threaded connectors 44, the supporting blocks are bonded with the side plates, the edge strips are bonded with the supporting blocks, and the spacer bars are bonded with the hollow coils 10.
Referring to fig. 2 and 4, the shielding layer 20 is Jiong-shaped and formed by bending a steel plate, the left and right sides of the bottom of the shielding layer are provided with fixing edges 21, the fixing edges are provided with mounting holes 22, and the mounting holes are matched with fixing pieces to fixedly mount the shielding layer on the base, so that the distance between the left and right side walls of the shielding layer is fixed, and the bracket, the plurality of hollow coils 10 and the spacing bars 30 can be stably clamped between the left and right side walls of the shielding layer.
The above description is only for the preferred embodiment of the present invention, and for those skilled in the art, there are variations on the detailed description and the application scope according to the idea of the present invention, and the content of the description should not be construed as a limitation to the present invention.
