Description

The non-circulating type electrode lay-out design of three-phase electrode formula humidifier

Affiliated technical field

This programme relates to a kind of design of three-phase electrode formula humidification apparatus, especially to the design of the strict application scenario of installation space.

Background technology

At present, the electrode lay-out that electrode humidifler adopted of known employing three phase mains is a regular polygon circulating type layout designs, by we can see their common trait among Figure of description Fig. 1, Fig. 2, Fig. 3: in all three phase mains humidifications were used, high-potential electrode was regular polygon and distributes around a center of circle (1).

Below I utilize three-phase circulating type electrode lay-out to analyze the operation logic of conventional humidifier, when conducting medium (water) when touching charged three-phase electrode simultaneously, electrode produces electric current and begins power conversion by medium (water) conducting, the medium (water) of this moment is that lead also is equivalent to load simultaneously, between power on condition bottom electrode and the electrode, produce electric current simultaneously between electrode and the center of circle, begin electric energy is converted into heat energy.We know that the three-phase electrical appliance has a design principle, and that must guarantee that exactly threephase load is evenly distributed.Traditional electrode humidifier all is this design principle that the electrode by adopting same specification satisfies according to the circulating type layout of regular polygon.Such layout can guarantee between each phase electrode and electrode, have identical effective conductive area and conduction distance between electrode and the center of circle, therefore can make each phase load equilibrium of three phase mains.All on the market three-phase electrode humidifications all are by this kind circulating type layout type electric energy to be converted into heat energy to make the water boiling produce steam at present.See the circuit theory among Figure of description Fig. 1, Fig. 2, Fig. 3 for details.

We can see a notable feature of conventional in layout mode by above-mentioned analysis, are exactly that all electrodes all are the regular polygon distribution around a center of circle (1).Therefore be based upon the electrode humidification apparatus on this design basis, its vapor generating cavity is circular design all.Because the structural core of electrode humidifier is a vapor generating cavity, that is to say that vapor generating cavity has determined the overall structure outward appearance of humidifier, so such electrode lay-out has fundamentally just limited the electrode humidification method in the higher environmental applications of some space requirements.

Summary of the invention

For overcoming the application limitation that existing three-phase electrode humidification apparatus exists, the invention provides a kind of new non-circulating type electrode lay-out scheme.This scheme can make each phase electrode of electrode humidifier no longer be the regular polygon distribution around a center of circle, and then makes vapor generating cavity need not be subjected to circular limitation again, designs the electrode humidifier that satisfies various different application space requirements on this basis.Therefore must satisfy following feature in new design: 1, the electrode plane position distribution no longer is subjected to circular constraint; 2, the framework threephase load connects; 3, threephase load equilibrium.By following two examples, can see how we realize this goal.

Exemplary applications 1

We can see a kind of application of new placement scheme in conjunction with Figure of description Fig. 4, Fig. 5.In this example, designed a public zero potential electrode 15, and with all high-

potential electrodes

16,17,18; 20,21,22,23,24,25 corresponding respectively these public electrode equivalences string out; When being all high-potential electrode energisings, when utilizing medium, only there is a kind of connected mode in the container with these electrode conductions---the threephase load that Y shape connects.From Fig. 3 with during circuit Fig. 4 is connected, the type of attachment of our load during this type of is used as can be seen.

Exemplary applications 2

In conjunction with the layout among Figure of description Fig. 7 signal with we can see the application scheme of the non-circulating type layout of mixing connection employing of three-phase Y-△ coexistence during circuit is connected.
