矿井采区供电设计毕业设计论文_精品.doc

摘 要 矿井采区供电是否安全可靠和经济合理，将直接关系到每一位井下工人的人身安全和矿井的可持续发展，特别是在现代化的矿井生产中，随着生产规模的不断扩大和新煤层的不断勘探，为了满足生产发展的需要，本次设计根据新采区的实际情况,对其所需设备及供电线路等进行了设计，本设计是以东源公司羊场煤矿井下采区供电为对象，在遵照《煤矿安全规程》、《矿山供电》、《矿井供电》等矿井相关书籍的前提下进行设计的，根据新采区的实际情况，在相关技术员的指导下，深入生产现场，并查阅了有关设计资料、规程、规定，听取和收录了现场相关技术员的意见及经验，对采区所需设备的型号及供电线路等进行了设计计算。设计时充分考虑到技术经济的合理，安全的可靠。采用新技术、新产品，积极采取相应措施减少电能损耗，提高生产效率，并阐述了采区供电系统中各用电设备的选型及其计算过程，如变压器、电缆、开关的选择等，并对其进行了整定和校验，设计中比较详细地叙述了矿用电缆及电气设备的选定原则以及井下各种保护装置的选择和整定。 ［关键词］： 矿山供电； 矿井电缆选择； 井下保护 ABSTRACT whether the power supply of a pit collect area is safe and thrifty or not is affect workers’ person safety and the pit’s continued develop directly ,especially in the contemporary pit’s produce .Along with the scale of production is wider and wider and the exploration of the new coal bed is more and more profoundly. In order to content the need of the production’s develop .This design is on the basis of the reality situation of the new mining area. We have made a design on all the equipment and the power supply line .The design’s target is the power supply of Eastern Coal Cause Company Yang Chang. And this design is carried out by the premise of the Coal Mine Safety Rules, Mine Power Supply, Pit Power Supplyand so on .And this design is coincide with the reality situation of the new mining area. Before making it we looked around the site situation road some concerned books, rules, and formulate. When we made it we listen to the guide of concerned technician and listen to and take down the ideas and experience of the present technician .Besides we have made a plan of the equipment as well as its type. We fully think of the rationality of its technique and economy as well as its reliability of safety. We use new technology new produce and take some advanced measures to reduce the wastage of electric energy increase produce efficiency. Besides we have expounded the process of choosing power supply equipment’s type and their planning process such as transformer, electric cable switch and so on. We proo
