With the development of science and technology and the discovery of new materials, in order to meet different needs of use, more and more diverse capacitors are emerging. Capacitors differ mainly in the medium, performance, capacity, structure, environment and environment. The use is also different.

The characteristics of capacitors are: 1. It has charge and discharge characteristics and the ability to block the passage of DC current, allowing AC current to pass. 2. During the charging and discharging process, the charge on the two plates has an accumulation process, that is, the voltage has a

1. The capacitor is allowed to operate for a long period of time at no more than 1.1 times the rated voltage, and can operate for no more than 30 minutes every day and night at 1.5 times the rated voltage (except for transient overvoltage). In order to extend the life of the capacitor, the capacitor

Capacitors are indispensable electronic components in the electrical and electronic industry. The manufacturing process can be said to be quite mature, but it is inevitable that problems will arise when using them. Among them, there are problems with the quality of the capacitor itself, and it is co

With the development of science and technology and the discovery of new materials, in order to meet different needs of use, more and more diverse capacitors are emerging. Capacitors differ mainly in the medium, performance, capacity, structure, environment and environment. The use is also different.

The role of reactive power compensation and the characteristics of capacitors The main function of reactive power compensation is to increase the power factor to reduce the equipment capacity and power consumption, stabilize the voltage and improve the quality of power supply, improve system transmi

3) The failure caused by the disappearance of the capacity of the capacitor and the complete leakage of electricity are the most difficult to identify and repair the failure of the capacitor in the power supply. Because the capacitor is measured, everything is normal with the multimeter, but the cap

What happens when a capacitor is damaged in a power supply? Common capacitors are ceramic capacitors, multilayer ceramic capacitors, high-voltage capacitors, and safety capacitors. 1) Short and open circuit damage inside the capacitor. The fault phenomenon is to burn out the switch tube and other cu

①Operation overvoltage causes damage to the capacitor:When the shunt capacitor bank is cut off, it may cause the oscillation process of the inductance capacitance loop. Thus, the operation overvoltage is generated. During the cutting process, if the circuit breaker reigns, it will cause strong elect

Intersecting. A capacitor is a container in which charges are stored. It is made up of two pieces of metal close to each other, separated by insulating material. A variety of capacitors can be made according to the insulating material. Such as: Mica, porcelain dielectric, paper dielectric, electroly
