What is the phase-shifting capacitor, what is the difference between it and the general capacitor
And the phase-shifting capacitor has the function of changing the phase of the alternating current signal in addition to the characteristics of the general capacitor. The answer can be compensated by the power factor compensation in parallel with the phase-shifting capacitor, and the phase-shifting capacitor can be used to produce the phase-shifting capacitor fault diagnosis device.
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.
After the power is turned off, the charge will not disappear, nor will it be neutralized (after all, between the two plates is insulated, positive and negative charge can only attract each other, and can not be combined), so that the potential difference has been there until you To discharge, the bipolar plate with a wire, the electrons along the wire from the lower plate to move to the upper plate, the potential difference disappeared.
The lower plate with a negative, so that the formation of potential difference between the two poles. And the positive charge does not move, only the negative charge - the electron will move, so the electrons along the plate along the wire, the power positive - negative move to the lower plate, so that the two plates will bring dissimilar charge. With the movement of electrons, the charge of the bipolar plate is more and more, the voltage is getting bigger and bigger, and the power supply potential difference is equal, it is full of electricity.
Assuming a capacitor has upper and lower poles, the upper plate is connected with the positive pole, the lower plate is connected with the negative electrode, connected with the power source, the potential difference between the two plates is formed, and the potential difference between the two electrodes is equal,
