Q:What is the difference between the power capacitor and the complement?
Wiring, three-phase complementary capacitor has three terminals, respectively (A, B, C) sub-capacitor has four terminals, respectively, then
Q:Capacitance for AC and DC effects?
In the sine wave AC circuit, the current size of the current flowing through the capacitor can be quantitatively calculated. Specifically, the voltage U is in volts (V), the current I is in the unit (A), the capacitance C is expressed by the law (F) (Ω), the frequency of the AC power supply is expressed in Hertz (Hz) units, and the frequency of the AC power supply is expressed in Hits (Hz)
Q:Does the size of the capacitor affect the power consumption?
The capacitance is the physical quantity that characterizes the capacity of the capacitor to charge the charge.We charge the capacitance of the capacitor by increasing the potential difference between the two plates of the capacitor by one volt.
Q:Why some Y capacitor is very small, and some Y capacitor is very large?
In line between the line of fire and zero line suppression capacitor, commonly known as X capacitance. As the location of the capacitor connection is also more critical, the same need to meet the relevant safety standards. X capacitance is also one of the safety capacitors. According to the actual needs, the capacitance value of the X capacitor is larger than the capacitance of the Y capacitor. However, it is necessary to connect a safety resistor in parallel with the X capacitor to prevent the charging and discharging of the power supply line.
Q:Use capacitance to do transformer how to calculate
The principle of capacitor buck is not complicated. His working principle is to use the capacitor at a certain AC signal frequency to produce capacitive reactance to limit the maximum operating current. For example, in the 50Hz frequency conditions, a 1uF capacitance generated by the capacitive reactance of about 3180 ohms. When 220V AC voltage is applied to both ends of the capacitor, the maximum current flowing through the capacitor is about 70mA.
Q:What is the principle of capacitance isolation?
When the capacitor is connected to the DC circuit, there will be a brief charging process. When the positive and negative plates are filled with charge (when the voltage across the capacitor is equal to the supply voltage), there is no current and then flow, so the capacitor is isolated DC current
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:Is the capacitor attached to the carbon foil positive?
The negative electrode of the capacitor is made of electrolyte, the electrolyte is generally composed of boric acid, ammonia, ethylene glycol and other components.
Q:What kind of capacitance can be divided into?
Commonly used capacitor structure and characteristics Commonly used capacitors can be divided into their dielectric materials electrolytic capacitors, mica capacitors, ceramic capacitors, glass glaze capacitors and so on.
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.
