A customized explosion-proof control cabinet introduces that there are incoming and outgoing cabinets in the low-voltage power distribution area, and of course capacitor compensation cabinets are indispensable. So what is the role of the capacitor compensation cabinet? As the name suggests, it plays a role in capacitor compensation. The principle of capacitance compensation, the capacitance and the load are connected in parallel when the capacitance is compensated. The capacitance is the same as the electric storage. When the load increases, the output voltage of the power supply will drop due to the internal resistance of the power supply, because the two ends of the capacitor must be maintained The original voltage, that is, the electric quantity in the capacitor must flow out partly, which delays the downward trend of the voltage, which is the principle of capacitor compensation.
In principle, a capacitor is equivalent to a generator that generates capacitive reactive current. The principle of reactive power compensation is to connect the installation with capacitive power load and the rational power load in parallel on the same capacitor, and the energy is converted between the two loads. In this way, the load on the transformers and transmission lines in the power grid is reduced, and the output effective power is increased. Under the condition of outputting a certain active power, the loss of the power supply system is reduced. In comparison, capacitors are a cumbersome and economical way to reduce the load of transformers, power supply systems, and industrial power distribution. Therefore, it is imperative for the capacitor to be used as the reactive power compensation of the power system. At present, the use of shunt capacitors as a reactive power compensation installation has been very common.
The above is an introduction to the customized explosion-proof control cabinet: the principle of capacitance compensation for low-voltage control cabinets.
