What is the difference between three-phase electrical socket single-phase socket and three-phase socket

Sockets are the most common and indispensable material in everyday life. Sockets are also categorized. The common ones are single-phase sockets and three-phase sockets ; home renovations use more of a single-phase socket, so many people don't know much about three-phase sockets . Today, Xiaobian gave everyone a detailed introduction about what is three-phase. The difference between sockets and single-phase sockets and three-phase sockets .

What is a three-phase socket

The three-phase socket is a device having a three-phase power supply. Each contact corresponds to a housing of a jack, which is characterized in that two plug-in seats are provided, and corresponding contacts thereof are connected by conductive sheets to form a two complementary plug-in seats. There is a separation plate between the jacks inside the housing.

Single-phase socket <br> Single-phase socket That is to say, when the socket is plugged in, and then there is only a single AC emf when the power is exchanged, there are generally two connector sockets for external power supply. The voltage of the single-phase socket is 220 volts. General household sockets are single-phase sockets.

Single-phase socket and three-phase socket difference <br> Single-phase socket power supply voltage is 220V, the socket panel hole has 2 holes (1 FireWire and 1 neutral line), three holes (1 FireWire, One neutral wire and one grounding protection wire), as well as a modular two-three-hole socket, with the same two-hole socket and three-hole socket.

The power supply voltage of the three-phase socket is ~380V, and the hole of the socket panel is 4 holes (connected with 3-phase fire wire and 1 neutral wire). The so-called phase line is usually referred to as the line of fire, the neutral line is usually referred to as the neutral line, and the grounding protection line calculates the usual PE line.

The above is the difference between the three-phase socket , single-phase socket, and single-phase socket and three-phase socket . If you want to know more about sockets or decoration, please pay attention to this site.
