4,The working principle
The capacitance compensation cabinet detects the power factor in the power grid, and when the power factor is lower than the set value, the control unit automatically judges and puts in the capacitor bank of the corresponding capacity to supplement the missing reactive power in the power grid. When the power factor is raised to a set upper limit, some or all of the capacitors are removed to keep the grid running optimally. This process is realized through cycle detection and intelligent control to ensure the efficient and stable operation of the power grid.
5. Application scenarios
Industrial production lines, especially those with a large number of inductive loads such as motors and transformers.
Commercial buildings, such as shopping malls, office buildings, to improve the overall power supply efficiency.
Residential quarters, optimize the power grid environment, reduce the load on the power grid.
Wind power, photovoltaic and other new energy power stations to improve the quality of grid-connected power.
6. Precautions for operation
Make sure the power supply is cut off before operation to avoid the risk of electric shock.
Regularly check the status of the capacitor bank and switching switch to ensure that there is no leakage, overheating, etc.
It is forbidden to perform maintenance or replacement operations while the capacitor is live.
Take care to keep the control unit clean and dry to avoid dust and moisture affecting performance.
Follow the product instructions and local electrical safety regulations.Fourth, the working principle
