Let's go through this chapter to understand the role of the lower parallel capacitor device and the harm of harmonics. 🌈Usually DC transmission converter stations are divided into DC area and AC area. Compared with conventional AC substation equipment, there are essential differences between DC area equipment and conventional AC substation equipment. There is no essential [...]
🌻An electrolytic capacitor differs significantly from other types in that its dielectric is an extremely thin anodic oxide film electrolytically generated on the valve metal, the thickness of which is closely related to the applied voltage. The oxide film is the heart part of the electrolytic capacitor, and its quality is related to the product performance, [...]
Guoju capacitor 1. According to the structure, there are three categories: fixed capacitor, variable capacitor and trimmer capacitor. 2. Classification by electrolyte: organic dielectric capacitors, inorganic dielectric capacitors, electrolytic capacitors, electric heating capacitors and air dielectric capacitors. 3, according to the use of: high frequency bypass, low frequency bypass, filtering, tuning, high frequency coupling, low frequency coupling, [...]
The basic unit of a electrolytic capacitor is Farah (F), but this unit is too large and is rarely used in field marking. Other unit relationships are as follows: 1F=1000mF 1mF=1000μF 1μF=1000nF 1nF=1000pF The deviation between the actual capacitance of the electrolytic capacitor and the nominal capacitance is called tolerance, and the accuracy is called within [...]
The capacitor utilizes a surface effect with two electrode plates 1: Suppose a piece has a positive charge on it, then the other side will have a corresponding positive charge, so that an electric field is formed between the two plates, and the potential difference of the electric field is the voltage. 2: Assuming that a [...]
