- Q: Low voltage capacitor voltage 0.45 and 0.4 What is the difference between usage
- Can be used in the low-voltage three-phase power lines on the line, but the level of different pressure, connected to the 400V line, 450V capacitor capacity is 79% of rated capacity, 400V capacitor capacity is rated capacity. In the use of life on the 450V longer than 400V
- Q: What is the relationship between capacitance and voltage?
- when you charge 5v, want to be in the first The capacitor is full, the second capacitor half; if you charge a higher voltage 6v, then the first capacitor to diffuse out, the actual performance of the capacitor was breakdown!
- 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: 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: What is the difference between the reactor and the capacitor?
- Reactor is the inductance ah, usually magnetic components plus winding wound, storage of magnetic field energy, the capacitor is stored in the electric field energy.
- Q: Does anyone know the difference between the stray inductance of the capacitor and the parasitic inductance?
- With the increase in stray inductance, IGBT turn-on loss will be reduced, the diode loss will increase. Stray inductance may also cause oscillations, such as oscillations caused by current mutations, which may result in limited device use due to EMI or overvoltage limits.
- 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: What is the electrolytic capacitor inside?
- Electrolytic Capacitor Features 1: the capacity of the unit volume is very large, tens of tons to several hundred times larger than other types of capacitors. Electrolytic capacitor features two: rated capacity can be very large, you can easily do tens of thousands of μf or even f (but not with the electric layer capacitance ratio).
- Q: Capacitance for AC and DC effects?
- Potential has a concept of space, referring to the electric field to a Coulomb charge from A to B work 1 joules, A on the B potential is 1 volt. The concept of potential for the circuit, specify a point of the circuit for the 0 potential, the other points are based on the point of the voltage is the potential of the other points. Electromotive force used in batteries, generators, is the power to generate voltage.
- Q: What is the difference between polyester film capacitors and ceramic capacitors?
- Polyester capacitor medium for the polyester film, its capacity and pressure range, small size, large capacity, high temperature, low cost. But tgδ with the frequency changes, it is used for tgδ, stability and loss requirements are not high occasions, such as DC and pulsating circuit.
