Background
The transmission and transformation project is a general name of transmission line construction and transformer installation project. The higher the voltage grade of power transmission and transformation engineering is, the larger the transmitted power is, and the longer the transmission distance is. The power transmission and transformation project with voltage over 33 ten thousand volts is called ultra-high voltage power transmission and transformation. The highest voltage grades of the ultrahigh voltage transmission and transformation lines put into operation in China are +/-1100 kV direct current transmission lines and 1000kV alternating current transmission lines, and the transmission projects generally referred to in the standards printed by HJ24-2014 of the environmental protection department can be divided into alternating current transmission and transformation projects and direct current transmission projects, wherein the alternating current transmission and transformation projects comprise transmission lines and transformer stations (or switch stations and series compensation stations), and the direct current transmission projects comprise transmission lines, converter stations and grounding electrode systems. The transmission of current often leads to because of the circuit generates heat and causes the loss, so all through the transformer step-up voltage, let the electric current diminish in order to reduce the loss that generates heat when carrying. High voltage electricity has a high risk, and the target electric appliance does not need such high voltage, which requires reduction of voltage by transformation. Since a plurality of times of power transformation is required in the current transmission process, the transmission of current is referred to as power transmission and transformation. The temporary power utilization cable on the construction site of the power transmission and transformation project needs to be buried in the ground or laid overhead.
