As we all know, energy is a major modern industrial production of energy and momentum. Power both easy conversion from other forms of energy from, but also easily converted into other forms of energy to supply the use. Electricity transmission and distribution both simple and economical, and easy to control, regulation and measurement, is conducive to the production process automation, and modern society, information technology and other hightech and both are built on the basis of puter applications. Therefore, in modern society, energy production and industrial life of the entire national economy wide range of applications. This design for a gas desulfurization plant supply and distribution system design, based on natural gas desulfurization plant three cases of electrical equipment workshop and production requirements, this design supply and distribution of natural gas desulfurization plants are classified first, to distinguish between one, two and three loads to determine the overall power train of thought, and fully guarantee the reliability of power supply. Then calculate the load, the power supply system of the enterprise in order to meet the requirements of the power factor for reactive power pensation. Determine the number of units and the main transformer substation capacity, linking methods, and then design the substation main electrical wiring, make the necessary shortcircuit current calculation, select high and low voltage equipment and the inlet and outlet and check substation secondary equipment and inlet and outlet, select tuning protection devices, lightning protection and grounding devices to determine supply and distribution ine guarantee safety. Keywords: supply and distribution of natural gas desulphurization plant； short circuit calculations； transformers； reactive power pensation； main electrical wiring； high and low voltage equipment； relay protection 重慶科技學(xué)院本科生畢業(yè)設(shè)計 目錄 目錄 摘 要 .............................................................................................................................
