Q: Low voltage capacitor voltage 0.45 and 0.4 What is the difference between usage: 0.45 capacitor used in the voltage level is high (for example, the transformer low voltage side voltage may reach 415V), with a tuned reactor (tuning reactor will increase the capacitor terminal voltage) situation; Note that the actual capacity of 0.45 capacitor nominal capacity (Actual voltage / 0.45) ^ 2 times;

Q: Use capacitance to do transformer how to calculate: Capacitance buck method: For example, we will be a 110V / 8W bulb and a 1uF capacitor in series, received 220V / 50Hz AC voltage, the light bulb is lit, the normal brightness will not be burned. Since the 110V / 8W bulb requires a current of 8W / 110V = 72mA, it is consistent with the current limiting characteristics of the 1uF capacitor.

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: Capacitance can pass high frequency resistance low frequency principle: This process of current flow will soon end, the specific length of time and the resistance of the circuit and the size of the capacitor, the larger the size of the product the greater the charging time, the shorter the contrary. After charging is complete, the voltage across the capacitor is equal to the size of the DC supply voltage

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 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: 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 to judge the capacitor is good or bad?: Measurement, the choice of multimeter R × 10k block, with two test leads were any then the capacitor of the two pins, the resistance should be infinite. If the measured resistance (pointer to the right swing) is zero, then the capacitor leakage damage or internal breakdown.

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.
