Three-phase power socket daily use problems Differences between three-phase power and two-phase power

In our lives, whether it is in the home or working place, as well as in outdoor public places, there will be three-phase power and two-phase power sockets, which are everywhere at any time. However, many people do not know much about what is the three-phase power and two-phase power. Simply speaking, three-phase power is a three-phase alternating current power supply and it is a form of power transmission. The two-phase electricity is two strands, one zero line and one fire line. Learn more about the daily use of three-phase power sockets and the difference between three-phase power and two-phase power.

Three-phase power socket daily use problem

1. We need to use three-phase power sockets every day in our lives. For example, some large household appliances in home kitchens need to use three-phase power. Then we are in the process of using three-phase power sockets. The ideal three-phase power should be a perfect sine wave, but some factors will deviate the waveform from sinusoidal, thereby creating power quality problems such as three-phase imbalance.

2. The reason why the three-phase power socket will lead to an unbalanced condition is that the harm caused by the uneven load of each line of electricity we use will bring us the danger of increasing the power loss and impact of the power line and distribution transformer. The safe operation of electrical equipment reduces the efficiency of the motor.

3. If we often use unbalanced load when using three-phase sockets, then lightening will reduce the line and the efficiency of the power supply. In severe cases, overloading with overloaded phase may result in the burnout of a phase wire. The switch burned out and even the single phase of the distribution transformer was burned, and then accidentally can cause serious consequences such as fire.

Difference between three-phase power and two-phase power

1, three-phase power socket We generally in the home kitchen, bathroom will be used more, are designed for relatively high power consumption of electrical appliances designed to take one of the phases and a zero is 220V. Take any of these two phases is 380V, according to the use of appliances marked distinction, the general home access line has a total power supply is 220V. However, some buildings have a three-phase junction box, which is designed by the designer considering that the user may use it.

2. So what do you know about the difference between three-phase power and two-phase power sockets? I think a lot of people don't know too much about it. Three-phase power sockets are generally power generators. Each phase of the three-phase power supply and its neutral point can constitute a single-phase loop, providing users with electrical energy. Note that the AC loop cannot be called positive or negative poles, and should be called line and neutral.

3, our country in accordance with the provisions of the general common power neutral point, is definitely not in the household end grounding, power supply is a FireWire and a zero line constitute a loop, in the single-phase three-core power jack also connected There is a grounding wire. This is in consideration of the realization of the function of the leakage protector. If the neutral point of the power supply is directly grounded, the leakage protector will lose its function and the short circuit between the human body and the electrical equipment cannot be protected.

Summary: Information on the daily use of three-phase power sockets , as well as information on the differences between three-phase power and two-phase power, is presented here. Hopefully, this will help everyone. If there is something that you don't understand, you can focus on more content.
