Background
The power transmission and transformation is like a large network which is distributed all over the country. The substations are nodes in the network. What connect each node is the transmission line, and the transmission line can be divided into again: steel towers, steel pipe poles, concrete poles, power cables and the like. The form of the iron tower is commonly seen everywhere on both sides of the highway. With the development of science and technology and the strong of the country, the power cable with high cost is applied slowly, and the way of changing from sky to underground embodies the social progress and civilization. The economic development speed of a country is closely related to the power transmission and transformation development of a power grid. If the mountain river is the blood meat of the country, the power grid is the nervous system of the country.
In the power industry, 35kV-1000kV is generally called power transmission and transformation, and 10kV and below is called distribution network. The power transmission and transformation can be simply divided into two main parts: 1. a transmission line; 2. and (5) a transformer substation. Generally, the voltage generated from a power plant is low, if the voltage is not boosted, the current on a line is high according to the proportion of the alternating current UI, and as the heating of the line is related to the resistance and the current, the heat generated by the same lead is high when the current is high, and most of the electricity generated from the power plant is lost on the lead. Also, the higher the heat of the wire, the more harmful the wire. In order to avoid the above adverse effects. The measure is to increase the voltage and reduce the current. A booster station is required. The first station through which electricity from the power plant typically passes is the step-up substation. The transformer substation generally has a booster station and a buck station, and the voltage grade is generally from small to large: 35kV, 110kV, 220kV, 500kV and 1000 kV.
