Description

Technical Field

[0001] The utility model relates to the technical field of capacitor compensation cabinets, in particular to a multifunctional capacitor compensation cabinet. Background Art

[0002] The majority of loads in power systems are inductive, and the widespread use of power electronics by electricity users results in a low power factor. A low power factor reduces equipment utilization, increases power supply investment, impairs voltage quality, shortens equipment life, and significantly increases line losses. Therefore, integrating capacitor compensation cabinets into the power system can balance inductive loads, improve the power factor, and thus enhance equipment utilization. To mitigate the energy waste and other negative impacts of low power factor, effective improvement of the grid's power factor is essential. Clearly, it would be unreasonable, and often impossible, for all this reactive power to be generated by generators and transmitted over long distances. A more effective approach is to generate reactive power where it is needed, namely by adding reactive power compensation equipment and devices.
