| Abstract: | The paper analyzes the problems existed in earth-leakage unearthing system underground coal mine. A new protective principle with which not only ensures the unity of protection judgment of main switch and of dispersive leakage protection. The commissioning of the new-developed protection for low-voltage neutral-point centralized control mode is put forward, branch switch, but also has the function product obtains a good result. |
