摘要
本文提出了在中性点对地绝缘方式的矿井高压电网中采用零序电流补偿法实现选择性漏电保护新方法。理论分析和实验表明,该方法简单可靠、灵敏度高。
A new method for the selective leakage protection system of high-voltage distribution network for mine using isolated neutral-point to ground — zero sequence current compensation method is presented in this paper. The theoretical analysis and experiments show that the method is easily implemented in the protection of a microprocessor based on simple, reliable operation and high sensitivity.
