摘要
分析了现有矿用移动变电站存在的缺点,设计了一种新型移动变电站。主要改进是在其高、低压侧配电装置的继电保护电路中引入了PLC(可编程序控制器)技术,提高了继电保护的安全性、可靠性和灵敏性,可有效进行线圈绝缘监测,并报警跳闸。使用实践表明,改进设计后的移动变电站既安全、可靠,又提高了生产效率。
For mining mobile transformer substation, the current existent shortcomings is analyzed, a new type is designed, the main improvement is PLC （Programmable Logic Controller） technology to be introduced in the relay protection circuit of its high and low-side switch to achieve the monitoring of coil insulation, and alarm trip, thus the security, reliability and sensitivity of relay protection is effectively improved. Implemented practices show that the mobile transformer substation of improved design has a great advantage and the future prospect of the use.
