Q:What is the difference between the reactor and the capacitor?

Reactor is the inductive load, there are series and parallel in series, the series is mainly used to limit the short-circuit current, parallel mainly used for ultra-high voltage long-distance transmission, the compensation line capacitance. Capacitors are capacitive loads that are used primarily to compensate for reactive and energy storage. Inductance and capacitance combinations for filtering and so on.

Q:How does the capacitor work? What does it do?

Straight to pass on the circuit need to pass the AC signal, power supply filter, cut off DC and other places to use. Capacitor charge and discharge is the basis of other properties. There are two kinds of filtering, one is the power filter, which is more obvious charge and discharge, can be seen as a container.

Q:Does anyone know the difference between the stray inductance of the capacitor and the parasitic inductance?

The stray inductance is represented by conductors in the circuit, such as connecting wires, component leads, element bodies, etc.

Q:How to use the capacitor

Circuites that are forbidden use: Even if the customer installs a solid-state aluminum capacitor in strict accordance with the welding conditions we have given, the leakage current of the solid-state aluminum capacitor may also increase or even increase significantly.

Q:What is the relationship between capacitance and voltage?

The larger the capacity of the capacitor, the larger the voltage, the smaller the capacity (uF). Since q = Cu, q is the current charge number of the capacitor, which is substantially proportional to the volume of the capacitor

Q:Why some Y capacitor is very small, and some Y capacitor is very large?

As a capacitor of the Y capacitor, it is required to obtain the certification of the safety inspection mechanism. Y capacitor appearance is mostly orange or blue, are generally marked with safety certification mark (such as UL, CSA and other logo) and pressure AC250V or AC275V words. However, its true DC withstand voltage is above 5000V. It must be emphasized that the Y capacitor can not be used with a nominal capacitor such as the nominal voltage AC250V or DC400V.

Q:How to identify high voltage capacitors is good or bad

Test the resistance at both ends with a multimeter. If the use of a pointer multimeter, and most of the same capacitor, you can see the pointer from small to large a swing process. The difference is not the last return to infinity, but 10m. Inexperienced friends may think that the capacitor breakdown or leakage, in fact, not.

Q:Why does the circuit current gradually decrease when charging the capacitor?

due to the increase in the number of charge, the electrostatic field field strength will gradually increase, increasing the field strength caused by the absorption of electrons to produce exclusion, So that the number of adsorbed charges gradually reduced, the number of charge to reduce the performance of the phenomenon that the charging current is gradually reduced. When the number of charges on the two electrode plates of the capacitor reaches a gradually increasing field strength constraint, the amount of charge is not increased and the equilibrium state is reached, that is, the charge saturation current is zero.

Q:What is the difference between the power capacitor and the complement?

Input compensation: three-phase co-fill capacitor input, the three groups of capacitors at the same time. The sub-capacitor can be put into operation separately.

Q:Cd capacitance to express what

Generally speaking, no sense of capacitance mainly refers to the IGBT protection with the surge absorption capacitor, it is no sense of the structure. If used to prevent the power grid surge, of course, but it is too wasteful.
