How To Convert Three Phase Electricity into Two-Phase Electricity? Wiring Method of Three-Phase Electrical to Two-Phase Electrical (1)
In the daily work of electricians, it is sometimes necessary to convert three-phase electricity into two-phase electricity to meet the needs of production. So, what is the method of converting three-phase electricity into two-phase electricity, and how to connect three-phase electricity to two-phase electricity, let's understand together?
Three-phase alternating current is a form of transmission of electrical energy, referred to as three-phase electricity.
A three-phase AC power supply is a power supply composed of three AC potentials with the same frequency, the same amplitude, and a phase difference of 120° from each other.
Three-phase alternating current has many uses. Most of the alternating current electrical equipment in the industry, such as electric motors, uses three-phase alternating current, which is often referred to as a three-phase four-wire system. In daily life, single-phase power is often used, also known as lighting power.
When lighting electricity is used for power supply, one phase of the three-phase electricity is used to supply power to electrical devices, such as household appliances. The other wire is the fourth wire among the three-phase and four-wire, that is, the zero wire, which is drawn from the neutral point of the three-phase electricity.
1. The connection method of three-phase electric to two-phase electric:
The color of three-phase electricity is yellow for phase A, green for phase B, and red for phase C. Currently, there are the following names: A, B, C or L1, L2, L3 or U, V, W, the order is the same.
It is enough to evenly distribute the three-phase power to the upper ends of the six air switches. The specific method is the three-phase power under the air switch is 1, 2, and 3 from left to right. The upper ends of the first two-phase air switch are connected to 1 and 2 respectively.
The upper ends of the second two-phase air switch are connected to 2 and 3 respectively; the upper ends of the third two-phase air switch are connected to 3 and 1 respectively. Then, the connection method of the fourth air switch is the same as that of the first air switch. The connection method of the fifth air switch and the second air switch is the same. The same is true for the sixth air switch and the third air switch. In this way, the three-phase distribution under the three-phase air switch is evenly distributed.
