Cylindric at present or honeycomb electrode container all adopts galvanized iron sheet machining or manually winds, it is necessary to repeatedly winding or metal stretching and molding, not only increases human cost and electric field production cost is increased substantially.In addition, for firm traditional cathode needle electrode, the modes adopting plastics draw-in groove collocation rivet fixing arrange fixing bar more, the process used deforms along with ageing of plastics, electric field produces the risk of spark discharge to be increased day by day, be easily caused cathode needle dislocation movement in electric field is by external force moving process and repair and replacement process, metal electrode deforms upon or fatigue break, causes that electric field cannot normal operation simultaneously.
Therefore those skilled in the art are devoted to develop a kind of uniform electric field arrangement of Electric Field Distribution.
Summary of the invention
Because the drawbacks described above of prior art, the technical problem to be solved is to provide a kind of uniform electric field arrangement of Electric Field Distribution.
For achieving the above object, the invention provides a kind of electric field arrangement, including negative plate, negative plate is provided with at least one electric field hole；
Arranging anelectrode in each electric field hole, the edge of each anelectrode is respectively provided with cutting edge；Anelectrode is arranged on fixing bar.
In order to improve the concordance of electric field intensity, each anelectrode and electric field hole are circle, and each anelectrode overlaps with the centrage in corresponding electric field hole respectively.
In order to improve the concordance of electric field intensity, as preferably, each electric field hole is being arranged on negative plate of array.
As preferably, it is 90 degree that cutting edge has the angle on the first limit and the second limit, described first limit and described second limit.
As preferably, the positive polar radius of electric field and electric field pore radius ratio are 18: 31 to 5: 9.
As preferably, anelectrode and negative plate all adopt aluminum or alloy material to make；Fixing bar adopts metal material to make.
The invention has the beneficial effects as follows:
1) Electric Field Distribution is uniform；
2) electric field production cost is reduced；
3) it is effectively prevented electric field and produces the risk of spark discharge；
4) effectively avoid that cathode needle dislocation is mobile, metal electrode deforms upon or fatigue break, cause that electric field cannot the situation of normal operation occur.
