LA cabinet LAS4+8 three-phase to single-phase connection?
Single-phase and three-phase are two common power supply methods in power systems. The main difference between them lies in the number of phases of the power supply and the phase of the voltage.
Single-phase:
A single-phase power supply system contains only one AC phase and is usually used for home and small commercial electricity.
In a single-phase system, the voltage and current have only one phase, that is, there is only one AC waveform.
A single-phase power supply system usually uses two wires, one is the phase line (also called "live wire" or "live wire"), and the other is the neutral line (also called "zero line").
A single-phase power supply system can provide a voltage of 220V (mainland China, Europe, etc.) or 110V (United States, Japan, etc.).
Three-phase:
A three-phase power supply system contains three AC phases, and the phase angle between each phase differs by 120 degrees.
In a three-phase system, the voltage and current have three phases, and the waveforms of each phase are staggered by 120 degrees from each other.
Three-phase power supply systems usually use four wires, three of which are phase wires (also called "live wires" or "live wires", corresponding to three phases), and the other is a neutral wire (also called "zero wire").
The three-phase power supply system can provide a voltage of 380V/220V (mainland China, Europe, etc.) or 208V/120V (USA, etc.).
The three-phase power supply system is usually used for industrial and commercial electricity because the three phases can balance the load, which can provide greater power and higher efficiency.
The three-phase power system is usually used in industrial and commercial scenes that require high power, but sometimes in some specific cases, it is necessary to convert three-phase electricity into single-phase electricity for use by specific equipment. The three-phase power supply can be converted to single-phase power supply by connecting the appropriate winding configuration of the transformer. Specifically, any two phases of the three-phase transformer can be connected together as a common neutral line, and the remaining third phase is output as a single-phase power supply. In this way, the original three-phase electricity is converted into single-phase electricity.
Three-phase electricity contains three phases, and there is a time difference between the voltages of each phase. Single-phase electricity has only one phase. In some application scenarios, the device may only need a single-phase power supply, or one phase of the three-phase power supply may have a voltage difference with the other two phases, and a separate power supply process is required. In this case, the conversion from three-phase to single-phase becomes particularly important.
