Description

Novel be convenient for radiating low-voltage capacitor cabinet Technical Field The utility model relates to the technical field of capacitor cabinets, in particular to a novel low-voltage capacitor cabinet convenient for heat dissipation. Background The load types in the power system mostly belong to inductive loads, and power electronic equipment is widely used by power enterprises, so that the power factor of a power grid is low. The lower power factor reduces the utilization rate of equipment, increases the power supply investment, damages the voltage quality, reduces the service life of the equipment and greatly increases the line loss. In order to improve the energy waste caused by the low power factor of the power grid and the factors of the unfavorable power supply production, the power factor of the power grid must be effectively improved. It is obvious that these reactive powers are often not possible if they are all provided by the generator and transmitted over long distances. A reasonable approach is to generate reactive power where it is needed, i.e. to add reactive power compensation equipment and devices. Therefore, inductive loads can be balanced and power factors can be improved by connecting a capacitance compensation cabinet (namely a low-voltage capacitance cabinet) in the power system, so that the utilization rate of equipment can be improved.
