Fire Safety---Xuansn Capacitor In order to promote the "enterprise" work of fire safety publicity, Xuansn Capacitor will effectively strengthen the enterprise's fire safety awareness and escape and self-rescue ability, and resolutely prevent and resolve major fire safety risks and hidden dangers. This afternoon, the Fire Rescue Brigade carried out in-depth fire safety drills. The drill [...]
1. Composition and structure of filter and parallel capacitors device 🍏The AC filter consists of high and low voltage capacitor banks (capacitor towers), reactors, resistors, lightning arresters, current transformers (oil-filled, silicone rubber, photocurrent transformers) and other metal connectors, supports, protective parts, etc. composition. The AC filters often used in the design of DC converter stations include [...]
🍏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 [...]
