矿井设备选型及供电系统设计

呼伦贝尔学院工程技术学院2011级机械设计制造及其自动化（机电方向）毕业设计I摘要煤炭是我国主体能源，是能源安全的基石，摸清煤炭的资源储量，评价煤炭资源储量开发利用前景，有利于我国煤炭工业规划的制定，有利于煤炭资源节约保护和合理开发利用。随着煤炭工业的现代化，综采工作面机械化程度越来越高，综采工作面机电设备容量不断增大，机械化程度的提高，为加快工作面的推进速度，提高生产率，对煤矿电气设备有了更高的要求，同时煤矿运行的生命线就是电。本次设计主要是为内蒙古呼伦贝尔市扎赉诺尔区灵露矿进行井下综采工作面设备选型和供电设计，设备选型以主要设备为主，通过选型负荷来确定井下供电系统，合理的选型不仅为工矿安全打下了结实的基础，而且在经济效益上也有显著提升。关键词：采煤机刮板输送机负荷统计变压器整定保护呼伦贝尔学院工程技术学院2011级机械设计制造及其自动化（机电方向）毕业设计IIAbstractCoalisthemainenergyinChina,isthecornerstoneofenergysecurity,findoutthecoalresourcesreserves,theexploitationandutilizationofcoalresourcesandreservesevaluationofprospects,conducivetothedevelopmentofChina'scoalindustryplanning,isbeneficialtosavingtheprotectionandrationaldevelopmentandutilizationofcoalresources.Withthemodernizationoftheindustry,fullymechanizedworkingfaceofincreasinglyhighdegreeofmechanization,capacityofelectromechanicalequipmentinfullymechanizedminingfaceisincreasing,thedegreeofmechanizationraise,tospeeduptheworkingfaceadvancingspeed,improvetheproductivity,therearemorerequirementsonthecoalmineelectricalequipment,atthesametimethelifelineofrunofminecoaliselectric.ThisdesignismainlyfortheInnerMongoliaHulunBuirCityDistrictofZhalainuoerdewminefullymechanizedminingfaceundergroundequipmentselectionandpowersupplydesign,selectionofequipmenttothemainequipment,todeterminetheundergroundpowersupplysystemthroughtheselectionofload,thereasonableselectionfortheindustrialandminingsafetynotonlylaidasolidfoundation,butalsoasignificantincreaseineconomicbenefit.Keywords:Shearerscraperconveyorloadstatisticsoftransformerprotectionsetting呼伦贝尔学院工程技术学院2011级机械设计制造及其自动化（机电方向）毕业设计III目录摘要...............................................................................................错误!未定义书签。Abstract.........................................................................................错误!未定义书签。绪论...............................................................................................错误!未定义书签。一、课题背景...........................................................................错误!未定义书签。二、课题意义...........................................................................错误!未定义书签。三、课题来源...........................................................................................................1第1章矿井基本概况...............................................................错误!未定义书签。1.1矿井基本概述.....................................................................错误!未定义书签。1.2矿井煤层情况.....................................................................错误!未定义书签。1.3设计方案确定.....................................................................................................4第2章井下主要设备选型设计..............................................................................52.1滚筒采煤机的选型............................................................................................52.2液压支架的选型...............................................................................................92.3刮板输送机的选型.............................................................错误!未定义书签。2.4胶带输送机的选型............................................................错误!未定义书签。2.5乳化液泵站与转载机的选择.............................................错误!未定义书签。2.6喷雾泵站与破碎机水泵的选择.........................................错误!未定义书签。第3章矿井供电系统设计....................................................................................203.1矿井供电简介.................................................................................................203.2采取变电所位置的确定.................................................................................213.3拟定采区供电系统的原则.............................................................................223.4采区主要设备.................................................................................................22第4章采区变电所设备选型...................................................错误!未定义书签。4.1采区负荷计算及变压器容量台数确定............................错误!未定义书签。4.2电缆型号及长度的确定....................................................错误!未定义书签。第5章采区电气设备选择校核...............................................错误!未定义书签。5.1采区高压开关柜的选择....................................................错误!未定义书签。5.2矿用低压隔爆开关选择....................................................错误!未定义书签。5.3真空磁力起动器的选择....................................................错误!未定义书签。5.4保护装置的整定计算........................................................错误!未定义书签。呼伦贝尔学院工程技术学院2011级机械设计制造及其自动化（机电方向）毕业设计IV第6章采区低压短路电流的计算........................................................................386.1综采工作面短路计算图..................................................................................39第7章井下照明、信号........................................................................................407.1井下固定照明.................................................................................................407.2采区接地保护措施.........................................................................................41结论.............................................................................................................................43参考文献......................................................................................................
