Cylindrical power capacitor is a kind of equipment widely used in power system, it has the advantages of compact structure design, high voltage resistance, low loss, long life, etc. It is suitable for the power system with high demand for power density and response speed. This capacitor is usually composed of two internal and external electrodes, separated by a medium, commonly used media including polypropylene film, polyester film and so on. Cylindrical power capacitors have the following characteristics:
Compact structure: cylindrical design, occupy small space, easy to install and arrange.
High voltage resistance: the dielectric has good insulation performance and high voltage resistance, and can withstand high voltage working environment.
Low loss: the internal use of low loss materials, reduce energy loss, improve the efficiency of the system.
Long life: the design has been carefully optimized, long service life, and can run stably and reliably.
Compared with other types of capacitors, cylindrical power capacitors have the following advantages:
High power density: It can provide higher power density and is suitable for power systems that require higher power density. Fast response: the response speed is fast, can quickly compensate the reactive power in the system, and adjust the harmonics, improve the stability and reliability of the system.
Wide band characteristics: with a wide frequency band characteristics, can adapt to a variety of frequencies under the compensation and correction needs.
Environmental friendly: the use of lead-free welding and environmental protection materials, in line with environmental requirements, no pollution to the environment.
In the power system, cylindrical power capacitors are mainly used in reactive power compensation, harmonic correction, high voltage stability and energy saving and emission reduction. It can compensate the reactive power in the power system, improve the power factor of the system, and reduce the loss of the grid; The harmonics in the power system can be corrected to improve the power quality of the system; Provide stable voltage output to protect the normal operation of power equipment; By improving the efficiency of the power system, reducing the ineffective power, to achieve the effect of energy saving and emission reduction
