Study on New-type Microcomputer Selective and Rapid Short-circuit Protection of High-voltage Distribution Network in Underground
This article combinates the status of short-circuit protection of coal mine in our country, studied the relevant principles and algorithms as well as enhancing the method of sensitivity and reliability of underground high voltage power short circuit protection in depth, designing three scheme of practical of underground selective high-speed short circuit protection by using the computer communications and logic identification technology put the computer applied in the coal mine. Through the multi-computer communication and logic judgment and adaptive current setting can verdict fault lines, then cut fault lines rapidly and selectivity and avoid large power outages of the coal mining because of the skip grade of tripping operation.
