Embodiment Construction
[0021] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings. Here, the exemplary embodiments and descriptions of the present invention are used to explain the present invention, but not to limit the present invention.
[0022] Under normal circumstances, the interference signal on the circuit cable may cause all the equipment on the circuit cable to be interfered, and there will be abnormal operation or even failure, resulting in failure to work. At the same time, all the equipment on the circuit cable will send out various Interfering with the signal affects the work of other devices. This effect is mutual, very fast, and even causes a chain reaction, causing all devices on the circuit cable to be paralyzed.
[0023] In order to suppress the interference signal during the transmissi...

The invention discloses a magnetic ring anti-interference method and device. The magnetic ring anti-interference method comprises the following steps: arranging three magnetic rings into triangles, sothat the connecting lines of the centers of the three magnetic rings form an equilateral triangle; winding a phase line of a first coil turn number and a neutral line of a second coil turn number oneach magnetic ring, wherein the first coil turn number is three times the second coil turn number. The invention realizes the equalization suppression of the interference signal, which can be appliednot only in the transmission process of the circuit cable, but also at the inlet or outlet of the user equipment.
Description
technical field [0001] The invention relates to the field of electronic circuits, in particular to a magnetic ring anti-interference method and device. Background technique [0002] This section is intended to provide a background or context to embodiments of the invention that are recited in the claims. The descriptions herein are not admitted to be prior art by inclusion in this section. [0003] As electronic devices become more and more popular, various electrical devices are connected to the same circuit cable, each electrical device will receive interference signals from other devices on the circuit cable, and each electrical device will generate interference signals , affecting the operation of other equipment on the circuit cable. Due to the advantages of the magnetic ring itself, it can solve the transmission of interference and suppress the amplitude of the interference signal, so as to achieve the effect of anti-interference. Therefore, the magnetic ring is a co...
