Compared with prior art, the utility model has the advantages that: by muti-piece measure copper sheet to different location on anode plate
Pico-ampere level current signal collect, plate current density under pattern, uniformity are matched in available specified pole, opening for pole with pattern
It hair and improves important guiding parameter is provided, avoid local current is excessive from causing that electric precipitator energy consumption increases and local current is too small leads
The problem of causing efficiency of dust collection to reduce.
The measurement copper sheet is that length is 2-4cm, width 0.5-1.5cm, thickness 1-3mm and is attached on anode plate, is surveyed
It measures and is insulated between copper sheet and anode plate by insulating film, spacing distance is 1.5-2.5cm between adjacent measurement copper sheet.Measure copper
Chip size is too small can not to be collected into enough pico-ampere level current signals, and measurement copper sheet size is analyzing entire anode plate electric current greatly very much
Relatively large deviation can be generated in uniformity, and be spaced between adjacent measurement copper sheet it is too small will increase a large amount of measurement point, be spaced too big
Current flow uniformity can not be accurately reflected.
The transfer element passes through anode plate to be measured and insulating film and is connected with measurement copper sheet.Insulating film avoids measurement electricity
Stream, which flows to anode plate, to be led to not measure signal, and transfer element passes through anode plate and exports electric field, solves hundreds of for measuring
The problem of a large amount of transfer elements of measuring point can not be arranged and transfer element are in the electric field to the interference of signal.
The transfer element is triaxle cable.External electrical field, side cable and the noise of laboratory are reduced to transmitting signal
Interference.
