Let's take a look at the design steps of the active filter cabinet together
2023-03-24
When designing an active filter cabinet, the following design steps are generally followed. 1. Design scheme for communication Based on the needs of filter characteristics, design a certain type of farth-order transfer function, and then dissolve the n-order transfer function into multiple low-level transfer functions to multiply.
The application of active filters in airports is crucial
Flight safety has always been a top priority in airport construction. As a convenient mode of transportation for people's daily transportation, airplanes have brought diverse choices to people's daily transportation and life. However, in the low-voltage distribution system of airports, there are a large number of harmonic sources, such as airport navigation lights, DC motors, electric furnaces, rolling mills, welding machines, etc. These harmonic sources have characteristics such as large current distortion, wide harmonic spectrum range, and rapid changes in reactive power demand, Becoming the first level of flight safety. Fortunately, an active filter has appeared at a critical moment, and its role is crucial. Harmonic hazards at airports
Teach you how to choose a power filter
The function of a power filter is to suppress electromagnetic noise. The function of a power filter is to obtain a specific frequency power signal or eliminate a specific frequency power signal rope by inserting a power filter into the power system. To prevent unnecessary losses, we need to understand the use of power filters. In order to use them, we also need to know how to choose a power filter, as follows:
Selection of various filters
According to the characteristics, frequency range, voltage, impedance and other parameters of the interference source, as well as the requirements of the load characteristics, a filter should be appropriately selected, generally considering:
