1、 1 矿用本安直流电源的设计 摘 要 电力是现代煤炭工业的主要动力，在煤炭生产中占有重要的地位， 是保证矿业生产的先决条件。矿井供电要求保证可靠，矿井供电中断 时不仅会影响原煤的生产产量，而且会导致矿井排水系统停止工作， 同时井下停电停风后，还会造成瓦斯积累，从而导致设备损坏、生产 停顿、危害井下人身安全，造成矿井的破坏，后果比较严重。 随着 煤矿管理现代化的提高, 本安设备越来越多地被煤矿所采用 。本安 电源作为本安系统不可缺少的组成部分 ,关系到矿井安全生产、抗灾 能力和矿工安危，其技术先进性和产品质量决定了本安设备的可靠 性 , 从而直接影响到监测系统数据采集的准确性、可靠性 、稳定 性

2、 。 据资料统计 ,电子设备的故障大约有 80%是由于电源引起的 。 因此 ,本安电源的质量 、技术发展水平越来越得到人们的重视 。本 文结合新版国家标准 GB3836. 4 - 2010 和安标国家矿用产品安全 标志中心的相关要求, 介绍了一种矿用本安直流电源的设计，并通过 仿真软件 Multisim 的调试验证，基本实现了矿用电源的要求。 关键词：本安直流电源 故障 Multisim 调试验证 2 Abstract Electric power is the main driving force of modern coal mining industry, coal production

3、 occupies an important position, is to ensure that the mining production prerequisites.Mine power supply requirements to ensure reliable power supply interruption, the mine will not only affect the coal production yield, but also causes the mine drainage system to stop working, and the underground p

4、ower to stop the wind, can cause gas accumulation, leading to equipment with bad, production to a standstill, endanger personal safety under the coal mine well, causing damage, more serious consequences.With the development of coal mine management modernization to improve, intrinsically safe equipme

5、nt is increasingly being used in coal mine. Intrinsically safe power as an indispensable part of intrinsically safe system, its advanced technology and product quality has decided the intrinsically safe equipment reliability, which directly affects the accuracy of data acquisition monitoring system,

6、 reliability, stability, matter to the safety in production of coal mine, the ability that fight calamity and miners. According to statistics, the electronic 3 equipment fault about 80% is the result caused by power supply. Therefore, intrinsically safe power supply quality, developing level of technology has been paid more and more attention. This paper introduces a kind of mine intrinsically safe DC power supply design, and through the Multisim simulation software debugging test, the basic
