Beijing capacitor manufacturers believe that capacitance is to hold and release the charge of electronic components. The basic working principle of capacitor is charging and discharging. Of course, there are rectification, oscillation and other functions. In addition, the structure of the capacitor is very simple, mainly composed of two positive and negative electrodes and an insulating medium sandwiched in the middle, so the type of capacitance is mainly determined by the electrode and the insulating medium. In the circuit of main board, card and power supply of computer system, electrolytic capacitor, paper dielectric capacitor and porcelain dielectric capacitor are applied, and electrolytic capacitor is the main one.
The paper dielectric capacitor is composed of two layers of positive and negative tin foil electrodes and a layer of insulating wax paper sandwiched between the tin foil, which is disassembled and folded into a flat rectangle. The rated voltage is generally between 63v and 250V, and the capacity is small, which is basically PF (skin method) order of magnitude. Modern paper capacitors are not easy to be aged due to their hard plastic shell and resin sealed packaging. They are basically working in low-voltage area and have relatively high withstand voltage value, so they are less likely to be damaged. In case of electrical damage, the general symptom is that the capacitor surface is heated.
1. Capacitor is mainly used in AC circuit and pulse circuit. In DC circuit, capacitor generally acts as the function of isolating DC.
2. The capacitor neither produces nor consumes energy and is an energy storage element.
3. Capacitor is an important device to improve the power factor in the power system; it is the main component to obtain the effects of oscillation, filtering, phase shift, bypass and coupling in the electronic circuit.
4. Because the load used in industry is mainly the inductive load of motor, the capacitive load should be combined to balance the power grid.
