This dust arrester is placed on the thermovent place of electrical equipment, connect high-voltage DC power supply, corona discharge electrode, dust collecting electrode, just establish an inhomogeneous field between dust collecting electrode and corona discharge electrode, corona discharge electrode surrounding electric field is maximum.Change the magnitude of voltage of high-voltage DC power supply, just can change the electric-field intensity around corona discharge electrode.When the breakdown electric field of actual electrical field intensity and air is close, air generation electric power, forms a large amount of cations and free electron.Free electron year electric field positive pole drift, the neutral molecule in drift process and in dust or particle collide, and these dust granules attract electrons have just become charged particle later, have so just made on original neutral dust lane negative electrical charge.Under electric field action, these electronegative dust granules continue to positive pole (dust collecting electrode) motion, and are finally attached in dust collecting electrode, and after dust is removed, disconnect high-voltage DC power supply, shake this device, dust granules just falls into grey box by ash-falling hole.
In order to realize the utility model better, further, the shape of described outer frame body is rectangle, and dust collecting electrode and outer frame body madial wall are fitted.
In order to realize the utility model better, further, described outer frame body bottom is also provided with adjustable pedestal.Use adjustable pedestal that this dust arrester can be enable to cover each gap of electrical equipment, stop dust to enter gap, dust stratification in electrical equipment, reduce appliance life.
In order to realize the utility model better, further, equally arrange between described dust collecting electrode, equally arrange between corona discharge electrode.
In order to realize the utility model better, further, described corona discharge electrode quantity is five.The quantity of corona discharge electrode as required except dust number arrange, preferably the quantity of corona discharge electrode is five here, and five corona discharge electrodes can meet most of dedusting demand, and concrete Dedusting Methods is depending on actual state.
The utility model compared with prior art, has the following advantages and beneficial effect:
(1) mode of the utility model electrostatic absorption makes the dust entering electrical equipment be adsorbed, do not have dust and enter electrical equipment inside by the louvre of electrical equipment, the heat spilt that heat radiation of electrical apparatus mouth goes out also can not be stopped, do not affect the normal operation of electrical equipment, the approach that in electrical equipment, dust enters is cut off from root, greatly reduce electrical equipment dust fall speed, extend the service life of electrical equipment;
(2) the utility model is applicable to outside the louvre of any electrical equipment, and occupation mode is various, the adjustable base that bottom is set up, and dust arrester can be enable to cover the gap of any electrical equipment, stops dust to enter electrical equipment inside, prevents laying dust in electrical equipment;
(3) the utility model structure is simple, low cost of manufacture, is convenient to maintenance and produces, suitable wide popularization and application.
