Description

technical field [0001] The invention relates to the technical field of power capacitors, in particular to a low-voltage intelligent reactive power compensation system device. Background technique [0002] Power capacitors, capacitors used in power systems and electrical equipment. Any two metal conductors separated by an insulating medium form a capacitor. The size of the capacitance of the capacitor is determined by its geometric size and the characteristics of the insulating medium between the two plates. When the capacitor is used under AC voltage, its reactive power is often used to represent the capacity of the capacitor, and the unit is var or kvar. The power capacitors on the market cannot protect the internal parts of the capacitor. The capacitors are damaged due to the overheating of the parts, resulting in economic losses for the users. They are large in size, complicated in field wiring, and inconvenient to maintain. Contents of the invention [0003] The pur...
