1. The difference between power distribution appliances and control appliances
Power distribution appliances: As the name suggests, it is a device that distributes electricity. Electricity, after coming out of the generator, is output by the bus, and can not be directly connected to the power equipment, and the demand is first output into the power station, which is the power distribution equipment, and the power station distributes the electricity from the generator to each main gate switch according to the demand, such as a switch tube is the lighting of the whole unit.
Control appliances: It is an electrical control equipment that is specially designed for different equipment. For example, when an electric motor rotates, it needs a starting control box, and this starting control box at least has its main contactor and stability. This control box is the control of the electrical appliances.
Second, the product advantages of power distribution appliances
Because ASVG does not need energy storage components to achieve the purpose of AC reactive power with the system, in fact, it uses DC capacitors to maintain a stable DC power supply voltage, compared with the AC capacitors used by SVC, the DC capacitance is relatively small and the cost is lower; In addition, when the system voltage is very low, the rated reactive current can still be output, and the reactive current compensated by SVC decreases with the decrease of the system voltage. It is precisely because of these advantages that ASVG has incomparable advantages in improving the voltage quality of the system and improving the stability, which also shows that ASVG is the direction of stopping the development of reactive power compensation technology in the future. In addition, with the development of power electronics technology, electronic active filters have been increasingly improved, because power active filters do not resonate with the power system when filtering out harmonics, so many power system workers are committed to the combination of power active filters and ASVG to eliminate the resonance problem generated by parallel passive filters in traditional ASVG equipment.

Delixi voltage regulator in the case of no load stable work?
Most modern LDOs and switching regulators operate reliably under no-load conditions, and some older power devices require a minimum load to ensure stability, because one of the electrodes that needs to be compensated is affected by the payload resistance. For example, the LM1117 requires a load current of at least 1.7 mA (most ...
