Abstract

The embodiment of the invention discloses a high-frequency electromagnetic wave suppression device which comprises a magnetic ring group. The magnetic ring group comprises a plurality of magnetic rings, wherein the number of the magnetic rings is determined according to the size of an electric dust remover and the capacity of a rectifier transformer, the magnetic rings are made from a magnetic material, and the resistance of the magnetic material is increased along with the increase of the frequency of electromagnetic waves. According to the device disclosed by the invention, the consumption of useful electric energy is greatly reduced while high-frequency electromagnetic waves generated by flashovers are suppressed, and the problems in the prior art are solved.

Description

technical field [0001] The invention relates to the technical field of electrostatic precipitator operation, in particular to a high-frequency electromagnetic wave suppressing device. Background technique [0002] Flashover refers to the destructive discharge of gas or liquid medium along the insulating surface under the action of high voltage. After discharge, the voltage between the electrodes drops rapidly to zero or close to zero. [0003] Electrostatic precipitator is an essential supporting equipment for thermal power plants. When the electrostatic precipitator is running, due to working conditions, changes in dust concentration and solubility, etc., the electric field will flashover, thereby generating high-frequency oscillating electromagnetic waves with a large amplitude and a wide frequency range, about tens of KHz to tens of MHz. These high-frequency electromagnetic waves will not only cause radio interference and affect the control device, but also be extremel...
