35 times 75 m, or approximately 4 acres of land; The investment in a substation is greatly affected by the equipment. For example, a similar size substation costs around 30 million (1 main transformer, SIG). does not include lines.
The fully indoor type covers an area of about 2,300 square meters, and the total cost is about 25 to 35 million (the choice of equipment varies
The line external depends); if it is an iron tower or cement pole line, if it is a double circuit tower, it should cost 1-2 million yuan/km; yuan/km.
I also disagree that the 110KV power supply upstairs should be drawn from the 220KV substation. It depends on the local power supply situation, and it can come from the 110KV substation. This must be decided by the local electricity department.
Detailed information
The large 110 KV substation poses six major risks:
First, the impact on the cardiovascular system: manifests itself as palpitations. , bradycardia, sinus arrhythmia, etc. ;
Secondly, the impact on the nervous system: manifests itself in memory loss, easy agitation, insomnia, headaches, etc. ;
Second third, the impact on the visual system: manifests itself as opacification of the lens and, in severe cases, cataracts, which are irreversible organic damage and affect vision;
Fourth, the impact on the reproductive system: manifested by decreased sexual function and quality of sperm in men can lead to spontaneous abortion and fetal malformations in pregnant women;
Fifth, being exposed to high electromagnetic radiation for a long time will cause changes in blood, lymph et of cellular protoplasm:
It affects the circulatory system, immunity, hormone secretion, reproduction and metabolic functions of the human body. In severe cases, it can accelerate the proliferation of human cancer cells and cause cancer, as well as. diabetes, hereditary diseases and other diseases. , it can also cause leukemia in children;
Sixth, patients with a pacemaker are in a high electromagnetic radiation environment, which will affect the normal use of the pacemaker. The impact of electromagnetic radiation on people over time is unimaginable.
Baidu Encyclopedia - Substation
Calculated based on installed capacity,
For example,
build a domestic solar power plant, the electricity consumption is about 10 kilowatt hours per day, and it pcould be installed with 4 kW, and it takes around 3.5 W to install one;
The more kilowatt hours of electricity used, the greater the consumption. the more power plant is installed, the more funds will be required.
