Detailed Description
Embodiments of the object presence validity determination platform of the present invention will be described in detail below with reference to the accompanying drawings.
High-voltage power transmission is a mode of transmitting the voltage output by a generator after boosting the voltage through a transformer for a power plant. The reason for transmitting power in this way is that in the case of power transmitted simultaneously, the higher the voltage, the smaller the current, so that high-voltage transmission can reduce the current during power transmission, thereby reducing the heat loss due to the current and reducing the material cost for long-distance transmission.
The electric energy generated from the power station is generally transmitted to various power utilization places through a transmission line. Different high voltages are adopted according to the distance of the transmitted electric energy. From the electricity condition of China, 220kV voltage is adopted for power transmission when the power transmission distance is 200-300 kilometers; 110 kilovolts is adopted when the distance is about 100 kilometers; 35 kilovolts or 66 kilovolts is adopted for about 50 kilometers; 10 kilovolts and 12 kilovolts are used at 15-20 kilometers, and 6300 volts is used in some cases. Lines with transmission voltages of 110kv and 220kv are called high-voltage transmission lines, lines with transmission voltages of 330kv, 550 kv, and 750kv are ultrahigh-voltage transmission lines, and lines with transmission voltages of 1000kv are called extra-high-voltage transmission lines.
