备自投装置在设计时应注意的问题

煤矿企业对供电可靠性有很高的要求，一旦中断供电，不仅会造成停产，还会导致保证矿井生产的一些重要设备，如煤矿企业中的通风、排水、提升等设备停止运转，危及井下工作人员的安全。文中通过对备自投装置跳、合闸保护出口接入点的分析，说明了不同保护厂家的备自投装置在设计时应注意的问题。

The problems that should be paid attention to when designing a self -casting device

Coal mining enterprises of power supply reliability have very high requirements,in the event of power interruption will not only lead to stop production, but also lead to ensure that mine production of a number of important equipments,such as coal mine ventilation,drainage,upgrading equipment to stop running, endangering the safety of underground staff.The prepared auto switch in device of jump,closing protection export access point analysis,indicating that the protection from different manufacturers of reserved auto switch on device should be paid attention to in the design of the problem.
