The construction of capacitor be by two panels very close to electrode conductor constituted, when in circuit voltage raise when, electricity
Extremely go up and can accumulate more electric charges, therefore, voltage is higher or area of electrode conductor is bigger, and the quantity of electric charge that can store just is got over
Many, capacitance is also bigger；Additionally, the dielectric property of the distance between two plate electrodes dielectric material (insulator) middle with it
Capacitance can be affected, electrode leans on must be nearer, the relation attracting each other due to positive and negative charge will accumulate more electricity on electrode
Lotus, so electric capacity is bigger；As for dielectric material for the impact of electric capacity, if dielectric constant is bigger, electrode can be accumulated more
Electric charge, so electric capacity is bigger.
High-voltage ceramic capacitor (wire-type ceramic capacitor) is using pottery as dielectric material, its in

The power supply unit of such as liquid crystal display must use high-precision high-voltage ceramic capacitor, and it is operated in 100 volts extremely
Alternating voltage between 5000 volts, capacitance is between several micromicrofarads (pF) to tens of micromicrofarads, and its error is necessary
It is equal to or less than ± 1%.
Existing high-voltage ceramic capacitor detection, mainly relies on artificial operation, namely manually by high-voltage ceramic capacitor
Lead be inserted in the wire inserting slot of capacitance detecting instrument, carry out capacitance detection.However, the high tension porcelain capacitance due to different model
Device, the diameter of its contact conductor is different, even if same model, diameter also can have deviation, in grafting, there is versatility
Not strong.As such, it is desirable to be equipped with many set detection means, equipment purchasing high cost, and need to frequently change, test error is big.
