Power capacitors, capacitors for power systems and electrical equipment. Any two metal conductors separated by insulating medium constitute a capacitor. The size of the capacitor is determined by its geometry and the characteristics of the insulating medium between the two plates. When the capacitor is used under the AC voltage, its reactive power is often used to express the capacity of the capacitor, with the unit of var or kvar.
The function of shunt capacitor
The shunt capacitor is connected in parallel with the bus of the system, similar to a capacitive load on the bus of the system. It absorbs the capacitive reactive power of the system, which is equivalent to the inductive reactive power from the shunt capacitor to the system. Therefore, the shunt capacitor can provide the system with inductive reactive power, the power factor of the system operation, and improve the voltage level of the bus at the receiving end. At the same time, it reduces the transmission of inductive reactive power on the line, reduces the voltage and power loss, and thus improves the transmission capacity of the line.
Function of capacitor:
1.Coupling: the capacitance used in the coupling circuit is called the coupling capacitance, which is widely used in the resistance capacitance coupling amplifier and other capacitance coupling circuits to isolate direct current and AC.
2.Filtering: the capacitor used in the filtering circuit is called the filtering capacitor, which is used in the power filter and various filter circuits. The filtering capacitor removes the signal in a certain frequency band from the total signal.
3.Resonance: the capacitor used in LC resonance circuit is called resonance capacitor, which is required in LC parallel and series resonance circuit.
4.Compensation: the capacitor used in the compensation circuit is called compensation capacitance. In the low-frequency compensation circuit of the card base, this low-frequency compensation capacitance circuit is used to improve the low-frequency signal in the playback signal. In addition, there is the high-frequency compensation capacitance circuit.
