The filter and shunt capacitor device test is a project that needs to be carried out after the equipment is newly installed or after the equipment is powered off. After the equipment is newly installed, the construction unit needs to carry out a handover [...]
1 AC filter and parallel capacitor operation 1.1 Manual switching of filters AC filters and parallel capacitors are the main capacitive reactive compensation equipment in the converter station. During the rated normal operation of the DC system, there are usually 1 to 2 groups [...]
Power capacitors are the most important equipment in the AC and DC filters and shunt capacitor devices of DC converter stations. Understanding and mastering the production process of capacitors is of certain practical significance for us to better maintain the equipment and handle faults [...]
1 Historical development of supercapacitor Supercapacitor first appeared in the middle of the 18th century. Pieter Van Musschenbrock of Leiden University in the Netherlands and Ewald Geory Von Kleist of Germany developed the Leyden jar, which is recognized as the prototype of all capacitors. [...]
What are the differences between solid capacitors and electrolytic capacitors? Solid capacitors and electrolytic capacitors are two capacitor products that we are more familiar with. Each of these two capacitors has its own functions and advantages. Different electrical appliances choose different types of capacitors. [...]
The main parameters of the capacitor include capacitance, rated voltage, loss factor, leakage current, and maximum operating temperature. These parameters are required in aluminum electrolytic capacitor data. In addition, aluminum electrolytic capacitors have parameters that are different from other capacitors. In addition to the [...]
1.1 Detection method of common capacitor When testing ordinary capacitors, you can first read the nominal capacitance of the ordinary capacitor to be tested according to the identification information of the ordinary capacitor, then use a multimeter to detect the actual capacitance of the [...]
Capacitors are represented by the letter "C" in circuits. The unit of capacitance is "farad", referred to as "law", represented by the letter "F". In practice, "microfarad" (expressed in "μF"), "nanofarad" (expressed in "nF") or picofarad (expressed in "pF") is more commonly used. The [...]
Carbon nanotubes Carbon nanotubes (CNT), also known as bucky tubes, belong to the Fullerian carbon system. In 1991, Professor Lijima discovered for the first time a nanometer-sized (1-100nm) multilayer tube, namely CNT, under a high-resolution transmission electron microscope when evaporating graphite electrodes using a [...]
Ceramic capacitors are a type of capacitor that uses ceramic as the dielectric material. They are widely used in electronic circuits due to their high capacitance-to-size ratio, low cost, and stability over a wide range of temperatures and frequencies. There are several ceramic capacitor [...]
