西安交通大學綜采工作麵供電畢業設計

摘　要
通過綜采工作麵選定的配套機械設備，正確選擇配套的電氣設備，以保證綜采設備能夠正常地投入運行。

綜采工作麵供電是否安全、可靠、技術和經濟合理，將直接關係到人身、礦井和設備的安全及采區生產的正常進行。由於煤礦井下工作環境十分惡劣，因此在供電上除采取可靠的防止人身觸電危險的措施外，還必須正確地選擇電氣設備的類型及參數，並采用合理的供電、控製和保護係統，加強對電氣設備的維護和檢修，以確保電氣設備的安全運行和防止瓦斯、煤塵爆炸。

綜采工作麵供電係統設計中，遵循煤礦企業對供電的基本要求及《煤礦井下供電設計技術規定》。根據工作麵用電設備的技術參數，對移動變電站進行選擇計算、高壓低壓電纜進行選擇計算、高壓低壓開關進行選擇、短路計算及繼電保護裝置進行整定。

ABSTRACT
Mechanized mining face by supporting selected mechanical equipment, electrical equipment supporting the right choice to ensure the fully mechanized mining equipment to normal operational.
Fully mechanized coal mining face power supply is safe, reliable, technical and economic rationality, will be directly related to the physical, mines and equipment, safety and production of normal mining area. As the coal mine working environment is very bad, so in addition to the power supply on the risk of electric shock and reliable measures to prevent the physical, but also have the right to choose the type of electrical equipment and parameters, using reasonable power, control and protection systems, strengthen electrical equipment maintenance and repair to ensure the safe operation of electrical equipment and to prevent gas and coal dust explosion.
Working Face the design of power supply system, follow the mine's basic requirements for power supply companies and the "technical requirements of Mine Power Design." Face of electrical equipment according to the technical parameters of the mobile substation to select terms, selection and calculation of high voltage low voltage cables, high pressure low pressure switch to choose short-circuit calculations and protective device setting.

KEY WORDS: Mechanized coal mining, Load statistical computing, Equipment Selection, Mobile Substation
