FAQ

How does the capacitor work? What does it do?

The other is the signal filter, that is, the case of alternating current, but also in the AC electrode polarity changes in the process of continuous charge and discharge, in order to AC, if not the capacitance of the two sheds with the amount of change, no matter how the AC can not pass.

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.

Cd capacitance to express what

Mainly used in high voltage, high current and high pulse circuit, such as buffer, energy converter, switching power supply, inverter and inverter protection circuit, especially for IGBT, SCR, Darlington line For absorption capacitors.

What is the use of capacitors?

As a passive component of the capacitor, its role is nothing more than the following; applied to the power circuit, to achieve bypass, decoupling, filtering and energy storage role, the following classification:

How to identify high voltage capacitors is good or bad

You have no voltage regulator, if there is, with a voltage regulator, an ammeter a voltmeter (available multimeter instead) to the capacitor plus an integer current (controlled by a voltage regulator), and then calculate the capacitance based on the voltage reading and current reading Impedance, and then divided by 3184 calculated by the tolerance value, the results and the capacitor nameplate on the standard almost no capacitance, and the other side of the capacitor is broken

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.

What is the capacitor, what is the use, where is there?

Capacitors are important devices in the power system to improve the power factor; in the electronic circuit is to obtain oscillation, filtering, phase shift, bypass, coupling and other major components of the role. Because the load used in the industry is mainly the motor inductive load, so the capacitor and the capacitive load to balance the power grid.

How to judge the capacitor is good or bad?

Multimeter selection R × 1k block. Both triodes have a beta value of 100 or more and a small penetration current. Can choose 3DG6 and other types of silicon transistors composed of composite pipe. The multimeter's red and black test leads are connected to the emitter e and collector c of the composite tube, respectively.
