摘要
针对当前井下低压电网环境下,使用馈电保护装置不足的问题,提出一种新型的综合性馈电保护装置,重点讨论该系统的工作原理、硬件结构、软件流程以及抗干扰技术,测试结果和使用情况表明,系统保护装置既保证了准确的动作电阻值和选择性。又提高了馈电系统的可靠性、稳定性且满足了实际应用。
In view of the low-voltage power grid current environment where there is not adequate feed protection equipment,a new integrated feeder protection is presented with emphasis on the working principle,hardware architecture,software process,and anti-jamming technology of the system.Testing results show that this system both guarantees accurate operation resistance value and selection and improves the reliability and stability of the power supply system and can be applied in practice.
