Description
Technical field
The present invention relates to technical field of electrostatic dust collection, especially relate to a kind of power supply for electrostatic precipitation.
Background technology
The operation principle of electrostatic precipitator is to utilize HVDC non-uniform electric field to make the gas molecule in flue gas ionize, produce a large amount of electronics and ion, move to the two poles of the earth under the effect of electric field force, encountering the dust granules in air-flow in moving process makes it charged, Charged separates with air-flow under electric field force effect and moves to opposite polarity pole plate or polar curve, Charged arrives pole plate or is adsorbed on pole plate or polar curve by electrostatic force during polar curve, makes dust fall into ash bucket by rapping apparatus so that gas cleaning.
General electrostatic precipitator is equipped with a Novel electric dedusting high frequency electric source, this power supply all includes the most several part, alternating current is become galvanic reorganizer by one, the inverter of one frequency alternating current that the unidirectional current that reorganizer exports becomes job demand, also has the transformator for the alternating current liter that inverter exports presses to job demand voltage.
Conventional commutator is all that the electronic original part such as diode or controllable silicon realizes becoming convert alternating current unidirectional current, in the case of power is relatively big, this rectifier system can cause bigger energy loss, and components and parts heat can be caused too high, so that the heat dissipation equipment of a lot of auxiliary.It is therefore desirable to improved.
Summary of the invention
The present invention is directed to deficiency of the prior art, it is provided that Novel electric dedusting high frequency electric source, greatly reduce energy consumption, it is to avoid the heat of components and parts is too high.
In order to solve above-mentioned technical problem, the present invention is addressed by following technical proposals: Novel electric dedusting high frequency electric source, including commutator, inverter and transformator, it is characterized in that: described commutator includes diode and relay, the live wire of described extraneous power supply coiler part with described diode and described relay successively is connected on zero line after connecting, described relay has a normal open switch and a normally closed switch, the two ends that described normal open switch intersects with described normally closed switch are connected, the live wire of described extraneous power supply switchs one end with described relay normally open and is connected, the described relay normally open switch other end is connected with described inverter, the described extraneous zero line of power supply is connected with the zero line of inverter.During use, when extraneous power supply can pass through diode, the electric current forward normal open switch by relay, when extraneous power supply can not pass through diode, electric current is back through the normally closed switch of relay, and this just by the alternating current of both direction, becomes the unidirectional current in a direction.Using the commutator of this structure, in addition to controlling a diode of side, do not use other electronic original part, and the diode of this control side is not over bigger electric current, even if therefore in the case of high power, loss is not the biggest.
In technique scheme, it is preferred that be provided with the electric capacity for filtering between the other end and the described zero line of described relay switch.
In technique scheme, concrete, described inverter includes two, motor input brush and two output brushes, a diverter and two output electrodes it are provided with in the rotating shaft of described motor, described diverter is one and is fixed in described rotating shaft the collar rotated together with described rotating shaft, described diverter is provided with the conducting block being mutually 180 degree a pair, two described input brushes contact with described diverter, and two described input brushes are oppositely arranged, two described conducting blocks turn on two described output electrodes respectively, two described output brushes are conducted with two described output electrodes respectively.Adopting in this way, inverter does not use any electronic devices and components, and therefore maximum possible avoids energy loss.
In previous technical scheme, input brush is the when that conducting block separating, it it is the conductive area being gradually reduced between conducting block, this resistance having resulted in circuit can be gradually increased, it is advantageous to, described input brush includes carbon brush, accommodate box and spring, described carbon brush is arranged in receiving box, described spring is arranged on the bottom of described carbon brush, under the effect of described spring, described carbon brush contacts with described diverter, the projection that insulant is made it is provided with on described conducting block, when described diverter turns to certain angle, described carbon brush props up described projection, under described convex role, described carbon brush moves in described receiving box.At this time contacting between carbon brush with conducting block turns off, it is to avoid is originally gradually reduced the contact resistance caused and increases.
Compared with prior art, the invention has the beneficial effects as follows: during use, when extraneous power supply can pass through diode, the electric current forward normal open switch by relay, when extraneous power supply can not pass through diode, electric current is back through the normally closed switch of relay, and this just by the alternating current of both direction, becomes the unidirectional current in a direction.Using the commutator of this structure, in addition to controlling a diode of side, do not use other electronic original part, and the diode of this control side is not over bigger electric current, even if therefore in the case of high power, loss is not the biggest.
