单电源双电压智能控制柜的研制

Research on Dual-voltage Single-supply Intelligent Control Cabinet

针对煤矿井下机电设备定期检修、出厂验收的实际需要,提出用一个干式变压器为不同电压等级的机电设备,提供与之相适应的供电电源的智能控制柜的设计方案,该方案具有结构简单、操作安全方便、保护完善的特点。重点介绍主电路、控制电路和保护电路。

For meeting the actual needs of periodic maintenance, factory inspection before delivery of electromechanical equipment underground coal mine, proposes a design scheme of power supply intelligent control cabinet by a dry-type transformer with voltages for different levels of mechanical and electrical equipment to provide with suitable power levels. The cabinet of scheme has the characteristics of a simple structure, safe and convenient operation and sound protection. The main circuit, control circuit, protection circuits, etc. are mainly introduced.
