🍏The configuration of AC and DC capacitor filters in the converter station is mainly based on the harmonic components and reactive power requirements of the AC and DC sides of the converter station, and the configuration of the parallel capacitors is based on the reactive power requirements of the AC side of the converter station. During [...]
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 [...]
1 Temperature characteristics of capacitance 🍏Are the parameters of aluminum electrolytic capacitors affected by the application environment?Capacitance varies with temperature. The change itself is determined by the rated voltage and capacitor size, from 25°C to the high temperature limit, the capacitance increase is generally not more than 10%. For the lowest rated temperature of -40℃, the [...]
1.1 Overview 😋Electrolytic capacitors should be called electrolytic capacitors because one of the electrical stages of such capacitors is not a metal but an electrolyte or metal oxide. In short, the conductive carriers of this electrode are no longer electrons but ions. This is the basic characteristic of electrolytic capacitors. Now. According to the characteristics of [...]
1 Overview 🐾Mica is an extremely important and excellent inorganic insulating material. As a dielectric material, it has not yet been found that the comprehensive properties of other materials can exceed mica. The advantages of mica are high dielectric strength, high dielectric constant, low loss, high chemical stability, good heat resistance, and easy shaving into thin [...]
