Product overview
SVG low-voltage reactive power intelligent compensation device adopts computer-aided design (CAD), introduces microcomputer control, and implements intelligent tracking compensation for reactive power. Its reasonable structure and advanced technology are widely used in low-voltage power grid, which can improve power factor, reduce reactive power loss, and improve power supply quality. It is a new generation of power-saving products. It is specially designed for reactive power compensation of 130-600kVA three-phase transformers.
Conditions of use
Upper ambient temperature +40℃; Lower limit -5 ° C.
The altitude does not exceed 1000m.
The daily average relative humidity is not more than 95%, and the monthly average is not more than 90%.
The intensity of the earthquake does not exceed 8 degrees.
There is no danger of fire, explosion, serious pollution, chemical corrosion and violent vibration.
Beyond the above environmental conditions, the user should consult with the manufacturer.
Performance characteristics
Using self-healing capacitor, its performance is much better than oil-immersed paper capacitor, capacitor components of the medium and plate have self-healing performance, low media loss, small size, large capacity, is a promising power energy-saving products.
It is equipped with automatic reactive power compensation controller, which can automatically cycle, step switch capacitor, and cut time interval can be adjusted, so that the reactive power consumption of the power grid is kept in the minimum state, so as to effectively improve the voltage quality of the power grid and reduce the loss of the transmission and distribution system and transformer.
The reactive power can be automatically adjusted according to the change of load, voltage fluctuation and power factor, and there will be no over-compensation or under-compensation phenomenon.
Manual or automatic switching is available. When automatic switching, switching at any time according to the change of power factor, no manual operation is required, and the automation of the control process is realized.
The use of special contactor switching capacitor can effectively suppress the impact of inrush current and high harmonic on the power grid.
Adopt a variety of protection: 1) single fuse or air switch protection; 2) Over-current protection; 3) Overvoltage protection; 4) Undervoltage protection;
Choosing the right capacity can increase the power factor to more than 0.95.
