采煤机瓦斯断电专用起动器的研究

Study on a Speical Starter to a Coal Cutter Power Cut by Methane

本文研究了采煤机机载式瓦斯遥控专用磁力起动器。该专用智能磁力起动器通过 5芯电缆与采煤机连接。当瓦斯超限时 ,信号通过 5芯电缆中 2芯控制先导回路的信号线在起动器中遥控采煤机断电 ,以保证工作面的安全。

A spcial magntic starter by methane remote control fixed on a coal cutter is studied in the paper.It can be connected with the coal cutter through a 5 core cable.When the time limit of methane is over,a signal in the starter telecontrols the coal cutter off through 2 core cables of the cable in the control circait to kecp working surface safe.
