Nowadays, electricity has been integrated into our daily life. Since we are used to the convenience provided by electricity for life, we can't live without electricity every day. Electricity has become one of the most basic energy sources in people's production and life. So how exactly is electricity sent home?
As soon as the finger is broken and the light is on, this is the magical existence of electricity, so that ordinary electrical equipment can burst out different charm! There are many members of the power generation family, such as hydropower stations, thermal power stations, nuclear power stations, etc. Although there are many kinds of power stations, they are inseparable from their ancestors. All of them have been transformed into electric energy through generators. Since the electricity is generated, it will be transmitted to the user's home. This process is power transmission.
Electricity is transmitted from the high-voltage line standing in the field to the power end. The "brother in need" accompanied by power transmission is substation. Because the voltage of each power plant is different, although the voltage of many power plants is as high as thousands of volts, it can not meet the requirements of long-distance transmission current. According to the requirements of different transmission lines, the power at the power generation end will first undergo the step-up of the substation, and then transmitted to the step-down substation in the power consumption area through the transmission line for step-by-step step step step step step step step-down, and finally reduce to the power demand at the power consumption end.
Electricity has completed its long march and worked hard to reach the power end. It's time to show your skills. Unfortunately, the needs of users are diverse. Users include ordinary household users, industrial users, commercial users, etc., so distribution on demand is extremely important. Then the distribution substation will take over this task with honor and be responsible for the power distribution in the area under its jurisdiction. After the substation reduces the high-voltage power to low-voltage power, it is connected to the distribution substation. The distribution substation carries out personalized voltage treatment, which is divided into 220V, 380V and other voltages, and then connected to residential areas and industrial areas respectively, so as to finally serve different users.
The power consumption of the whole country changes from time to time every day, so how do power plants know how to generate enough power reasonably? Ha ha, don't worry. The power dispatching center will help solve this problem. It is specially responsible for monitoring the power consumption of various regions at all times and allocating the power. Therefore, the power is basically balanced between supply and demand in real time. Even if there are occasional fluctuations, it is within the controllable range.
After the exciting power transmission process, do you think it is long or even complex? But in fact, this is only a moment. The transmission speed of current is about the speed of light, and it can circle the earth's equator 7.5 times per second. So even if he wants to spread from the northernmost end of the earth to the southernmost end, it's only a moment.
