Description

A kind of dynamical electric precipitation high frequency electric source

Technical field

The utility model is related to technical field of electrostatic dust collection, more particularly, to a kind of power supply for electrostatic precipitation.

Background technology

The operation principle of electrostatic precipitator is to ionize the gas molecule in flue gas using HVDC non-uniform electric field, is produced The a large amount of electronics of life and ion, move, the dust granules in encountering air-flow in moving process in the presence of electric field force to the two poles of the earth Make its charged, Charged is separated with air-flow under electric field force effect and moved to opposite polarity pole plate or polar curve, Charged Adsorbed on pole plate or polar curve by electrostatic force when reaching pole plate or polar curve, dust is fallen into ash bucket by rapping apparatus so that cigarette Gas is purified.

General electrostatic precipitator is equipped with a dynamical electric precipitation high frequency electric source, and this power supply all includes So several parts, alternating current is become galvanic reorganizer by one, and the direct current that reorganizer is exported is become work by one The inverter of the frequency alternating current of needs, also turns into the change of need of work voltage for the exchange electric boost for exporting inverter Depressor.

Conventional inverter be all using the electronic component such as metal-oxide-semiconductor field effect transistor or IGBT igbts come The commutation of electric current is realized, in the case where power is larger, this inverting can cause larger energy loss, Er Qiehui Cause component heat too high, so that the heat dissipation equipment of many auxiliary.It is therefore desirable to be improved.

The content of the invention

The utility model is directed to deficiency of the prior art, there is provided a kind of dynamical electric precipitation high frequency electric source, greatly Greatly reduce energy consumption, it is to avoid the heat of component is too high.

In order to solve the above-mentioned technical problem, the utility model is addressed by following technical proposals：It is a kind of dynamical Electric precipitation high frequency electric source, including rectifier, inverter and transformer, the inverter include motor two inputs brush and two Individual output brush, is provided with a commutator and two output electrodes in the rotating shaft of the motor, the commutator is one solid It is scheduled on the collar rotated together with the rotating shaft in the rotating shaft, the commutator is provided with the conducting block for being mutually 180 degree for a pair, Two input brushes are in contact with the commutator, and two input brushes are oppositely arranged, two conducting blocks Respectively with two output electrode conductings, two output brushes are conducted with two output electrodes respectively.Rectification The when direct current that device input comes, that is to say, that the polarity of electricity is all fixed on input brush, but conducting block is ceaselessly Rotated along motor, so conducting block can be in contact from different input brushes, cause that alternating current can be derived on output brush. Inverter in this way is adopted, completely useless to electronic device, whole losses are exactly only line loss and motor Loss, so substantially increasing Energy Efficiency Ratio.When input brush is that conducting block is separated, it is gradually reduced between conducting block Conductive area, this resistance for having resulted in circuit can gradually increase, and it is recessed to be that this described conducting block is slidably connected at including one Movable block on groove, the bottom of the movable block is provided with spring, is provided with what insulating materials was made on the movable block periphery Projection, when the commutator turns to certain angle, the input brush is in contact with the projection, and the movable block is being pushed away The inside grooves are slipped into the presence of power so that the input brush is separated with the movable block.The inverter of this structure, Separation between its input brush and conducting block be it is instantaneous complete, in the absence of resistance gradually increased stage, therefore efficiency Greatly improve.

In previous technical scheme, it is preferred that the raised centre position circumferential positioned at the sliding shoe.So ensure to slide The thrust that motion block is subject to is in the same direction with groove.

In above-mentioned technical proposal, specifically, the rectifier includes diode and relay, the live wire of the extraneous power supply It is connected on zero line after being connected with the coiler part of the diode and the relay successively, the relay has one often Switch and a normally closed switch, the two ends that the normal open switch intersects with the normally closed switch are connected, the extraneous power supply Live wire switchs one end and is connected with the relay normally open, and the relay normally open switch other end is connected with the inverter, institute The zero line of extraneous power supply is stated to be connected with the zero line of inverter.When using, when extraneous power supply can by diode when, electric current is positive By the normal open switch of relay, when extraneous power supply can not by diode when, electric current back through relay normally closed switch, This becomes the direct current in direction just by the alternating current of both direction.Using the rectifier of this structure, except control side Beyond one diode, without using other electronic original part, and the diode of this control side not over larger electric current, because Even if this is in the case of high power, loss is not very big.

In above-mentioned technical proposal, it is preferred that be provided between the other end of the relay switch and the zero line for The electric capacity of filtering.

Compared with prior art, the beneficial effects of the utility model are：The when direct current that rectifier input comes, that is, The polarity for saying electricity on input brush is all fixed, but conducting block is ceaselessly being rotated along motor, so conducting block can be with Different input brushes are in contact, and cause that alternating current can be derived on output brush.Inverter in this way is adopted, is not had completely Electronic device is used, whole losses are exactly only the loss of line loss and motor, so substantially increasing Energy Efficiency Ratio.
