朱仙庄矿35kV/6kV变电所综合自动化改造

Integrated Automation Reform of 35kV/6kV Substation of Zhuxianzhuang Coal Mine

朱仙庄矿位于安徽省淮北平原中部,设计生产能力为每年120万t,经过改造现年产200万t以上,许多设备严重制约产量的提升。为保证安全高效生产,对矿井供电质量、可靠性的要求也逐渐提高。被定为"双突"矿井后,电磁式保护已不能满足供电可靠性要求,遂决定对35 kV/6 kV变电所进行综合自动化改造。

Zhuxianzhuang mine is located in the central of Huaibei plain of Anhui province, which designed production capacity was 1.2 million tons per year. The annual production is more than 2 million tons after reforming and lots of devices constraints serious to enhance production. In order to ensure safe and efficient pro- duction, the requirements of quality and reliability of power supply is a gradual increasing. After the mine was designated as the ＂double process＂, the protection of electromagnetic can not meet the requirements of power supply reliability, so decided to reform the integrated automation of 35 kV/6 kV substation.
