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 Concept And types of Dislocation Capacitors - Dislocations in Aluminum. The structure of aluminum crystal given in Figure 1.1 and Figure 1.2 is an ideal complete structure. Studies have found that there will be certain incompleteness and defects in the three-dimensional arrangement of [...]
1.the Development of Capacitor Aluminum foil Processing Technology Capacitor aluminum foil processing-Aluminum electrolytic capacitors are the main varieties of capacitor products. It is estimated that the output value of aluminum electrolytic capacitors accounts for about 50% of the output value of all types of [...]
1 Snap-in electrolytic capacitor—Packaging form Snap-in electrolytic capacitor—are medium and large electrolytic capacitors, most of which are directly mounted on the circuit board. Since snap-in electrolytic capacitors come in a wide range of sizes, different pin patterns are required for reliable mounting on the [...]
1 How electrolytic capacitors work—Inverter arc welding power supply working mode How electrolytic capacitors work—Inverter arc welding power supply is a special working mode of high-power switching power supply. Its particularity is not only that the working characteristics of arc welding require constant current, [...]
1 Working status of electrolytic capacitors—The role of electrolytic capacitors in flyback switching power supplies 1.1 AC input power filter circuit Working status of electrolytic capacitors - low-power switching power supplies are widely used, requiring the cost to be as cheap as possible, the [...]
Most of today's electrolytic capacitors are used in power frequency or high-frequency rectification and filtering of power electronic circuits, power supply bypass with high ripple current, etc. Therefore, in addition to the traditional performance of capacitors: rated voltage, capacitance, loss factor, leakage current, modern [...]
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. [...]
