Working Principle of Lightning Arrester
July 11,2022
A lightning arrester is a lightning protection device connected between conductor and ground, which is usually connected in parallel with the protected equipment.
Some Knowledge of Composite Insulator
July 25,2022
If composite insulators are to be used more widely in China, it is necessary to break through people's understanding that they are mostly used to prevent pollution flashover and to shake the dominant position of traditional porcelain and glass insulators. To achieve this goal, we need to pay attention to the following issues and continue to conduct more in-depth research.
The Difference Between Arrester and Insulator
August 08,2022
A lightning arrester is an electrical device that can release lightning or simultaneously release the operating overvoltage energy.
Introduce Several Commonly Used Low-voltage Fuses
August 22,2022
The fuse has the advantages of simple structure, low price, convenient use and maintenance, and small size.
Is DC or AC for Transformer
June 10,2022
The transformer can only change AC power, and the change over is still AC power. Because the transformer works according to the principle of electromagnetic induction, it is a process of electricity generating magnetism and magnetism regenerating electricity. The frequency of DC is 0, so DC can not be changed through the transformer to change the voltage value.
How to Choose Transformer?
May 25,2022
How to accurately select the transformer capacity to ensure the reliable operation of power transmission? If the transformer capacity is too large, it will form the phenomenon of a "big horse pulling a small car", which will not only increase the equipment investment, but also make the transformer in a no-load state for a long time and increase the reactive power loss; If the transformer capacity is too small, the transformer will be in overload state for a long time, and it is easy to burn the transformer.
What Is a Polymer Fuse
May 12,2022
Commonly known as a fuse or fuse, a fuse is a non-recoverable fuse that can only be replaced with a new fuse after it has blown. It is indicated by "F" or "FU" in the circuit.
What Is a Disc Insulator?
April 27,2022
Disc insulators are also called suspension insulators. They are actually a piece of ceramic or glass with steel caps and iron feet at the upper and lower ends, which can be used in series.
