摘要
通过煤矿矿井供电系统工作面选定的配套机械设备,正确选择配套的电气设备,以保证综采设备能够正常地投入运行。
煤矿矿井供电系统工作面供电是否安全、可靠、技术和经济合理,将直接关系到人身、矿井和设备的安全及采区生产的正常进行。由于煤矿井下工作环境十分恶劣,因此在供电上除采取可靠的防止人身触电危险的措施外,还必须正确地选择电气设备的类型及参数,并采用合理的供电、控制和保护系统,加强对电气设备的维护和检修,以确保电气设备的安全运行和防止瓦斯、煤尘爆炸。
煤矿矿井供电系统工作面供电系统设计中,遵循煤矿企业对供电的基本要求及《煤矿井下供电设计技术规定》。根据工作面用电设备的技术参数,对移动变电站进行选择计算、高压低压电缆进行选择计算、高压低压开关进行选择、短路计算及继电保护装置进行整定。?

Abstract
Supporting machinery and equipment selected by the coal mine power supply systems face the correct choice of supporting the electrical equipment, to ensure that the mining equipment can be properly put into operation Coal mine power supply systems face power supply is safe, reliable, and reasonable technical and economic, will be directly related to the normal production of personal, mine safety and mining equipment. Coal mine work environment is very poor, so In addition to taking on the electricity supply reliable in preventing the type of personal electric shock hazard measures must also be the correct choice of electrical equipment and parameters, and power supply, control and protection system, strengthening maintenance and repair of electrical equipment to ensure the safe operation of electrical equipment and to prevent gas and coal dust explosion Coal mine power supply systems face power supply system design, follow the basic requirements of the coal powered and coal mine power supply design and technical requirements. Technical parameters of the electrical equipment according to the face, choose to calculate the mobile substation, high voltage and low voltage cable selection and calculation, the high pressure and low pressure switch to select short circuit calculations and protective equipment for tuning
