The device of voltage.
Background technology
There is a kind of phenomenon in aluminium electrolutic capacitor, carries out being substantially discharged process by aluminium electrolutic capacitor, but be placed as one
After the section time, between aluminium electrolutic capacitor positive and negative end, voltage can rise to a certain degree again, and this kind of phenomenon is exactly aluminium electroloysis
The regenerative voltage phenomenon of capacitor.
The mechanism of production of regenerative voltage is: when voltage is applied on medium, causes the transfer of electronics at media interior,
Thus producing induction field at media interior, its direction is in opposite direction with voltage, and this phenomenon referred to as polarizes reaction.Some
After medium is applied in voltage, polarizing than very fast, some is the most slow.If two-terminal carries out electric discharge electricity up between terminal
Pressure is zero, is then opened a way after placement a period of time, and a kind of potential electromotive force will appear in two-terminal, thus causes
Regenerative voltage.
Alminium electrolytic condenser regenerative voltage typically can reach about the 10% of rated capacitor voltage.That is high pressure produces
Product (more than 400V product) be likely to be breached 40 ~ 50V even more than.This just makes aluminium electrolutic capacitor can go out in the process that client uses
Now getting an electric shock, capacitor discharge causes some precision components of circuit board to be damaged.

Device and be fixed on insulation inner shell on, described insulation inner shell is fixedly installed on shell.
The device of regenerative voltage is eliminated, it is preferred that on described insulation inner shell, be provided with one on above-mentioned capacitor testing machine
Individual temperature sensor.
Regenerative voltage is that speed is uneven to be caused owing to electrolyte polarizes, and places, in both positive and negative polarity through long-term under room temperature
With, regenerative voltage can be gradually reduced, and can be reduced to a value the least through long time regenerative voltage.In the condition of high temperature
Under, the translational speed of particle can be aggravated, thus accelerates the process of polarization reaction, allows regenerative voltage in a relatively short period of time
It is reduced to safe degree.
