Information
In the low voltage distribution system, there are the incoming cabinet and the outgoing cabinet, and of course, can not be omitted. Then what role does the reactive power capacitor compensation cabinet play? As its name implies, it plays the role of capacitance compensation. First let's talk about the principle of capacitance compensation. The capacitor and load are connected in parallel. The capacitor is the same as a library. When the load increases, due to the internal resistance of the power supply, the output voltage of the power supply will drop. Because the two ends of the capacitor have to maintain the original voltage, that is, the electricity in the capacitor should flow out, which delays the downward trend of the voltage. The above is the principle of capacitor compensation. Below, let's talk in details why the low voltage distribution system should be equipped with the the reactive power capacitor compensation cabinet.
In the low voltage power system, there are devices which have coils in them, such as the motor, the reactor and so on. This kind of equipment obtains a part of the current from the line and perform their works, but also there is certain amount of inductive current is consumed in the line, which requires that an extra amount of current in the line should be provided. The power factor is used to measure this part of the current which does not work. When the inductive current is 0, the power factor is 1. When the proportion of the inductive current increases gradually, the power factor decreases gradually. Obviously, the lower the power factor is, the greater the additional burden on the line will be, and the greater the additional burden on the generator, the power transformer and the distribution equipment will be. In addition to reducing the utilization rate of line and power equipment, it will also increase the power loss on the line, increase the voltage loss and reduce the quality of power supply. Therefore, the power factor should be increased. The most convenient way to improve the power factor is to use the shunt capacitors, which produce a capacitance current to counteract the inductive current and reduces the so-called reactive current, i.e. the current which does not work, to be in a certain range. The reactive power supply, like the active power supply, is an indispensable part for ensuring the power quality. The reactive power should maintain balanced in the power system. Otherwise, the voltage of the system will be reduced, the equipment will be damaged, the power factor will be reduced, and in some serious cases, a voltage collapse even may occur, causing the system to break down and a large area of power outage. Therefore, It is of great significance to solve the problem of insufficient reactive power capacity, install additional reactive power capacitor compensation equipment and improve the power factor of the network for reducing the loss and saving the electricity, safe and reliable operation of the power grid.
