- Q: What is the phase-shifting capacitor, what is the difference between it and the general capacitor
- As long as connected to the power, there is an electric field circuit, or how to move the electronic. Remember that the point of connection with the wire is equal, the beginning, the pole and the power of the positive potential, the lower plate and the negative potential, potential difference is not zero, the formation of electric field, electronic movement, The plates are connected by wires, and the electrons move through the wires. The answer is not the same Oh, the terminal distribution of the low-voltage power distribution room is thousands of capacitors Oh, is not the same! Answer Replenishment Phase Capacitor Cabinet Concentrates the compensation power factor at the low voltage side of the transformer.
- Q: What kind of capacitance can be divided into?
- Aluminum electrolytic capacitor It is made of aluminum cylinder negative, which is equipped with liquid electrolyte, insert a curved aluminum belt made of positive electrode. Also need to go through the DC voltage treatment, so that the formation of an oxide film on the positive film to do the media. It is characterized by large capacity, but large leakage, large error, poor stability, often used for AC bypass and filter, when the request is not high when used for signal coupling. Electrolytic capacitors are positive and negative points, the use can not be reversed. There are positive and negative polarity, the use of time, positive and negative do not reverse.
- 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: What is the principle of capacitance isolation?
- The structure of the capacitor is two plates, separated by a layer of insulator, so under normal circumstances the capacitor is no current through (unless the middle of the insulation was breakdown).
- Q: What is the difference between the power capacitor and the complement?
- A total of three-phase compensation at the same time, sub-compensation is a single-phase compensation.
- 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: 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: 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: What is the capacitor, what is the use, where is there?
- In the electronic technology, used to consider the wave, phase, straight, bypass, frequency, etc. Almost all of the electronic products, household appliances are the following are some of the capacitor shape.
