新型矿用隔爆四回路智能组合开关的研究

THE NEW RESEARCH OF FOUR-CIRCUIT INTELLIGENT MINE FLAMEPROOF MULTI-FUNCTION SWITCH

本文介绍了一种煤矿掘进工作面用智能型组合开关,由主电路和控制电路组成。主电路和控制电路为两路对称形式,控制电路以PLC为核心,两路PLC之间相互连锁,两路电源分别供电,这样,无论其中哪一路的主电路或控制电路出现问题,其另一路都会自动或手动投入工作,确保煤矿掘进工作面具有风机运转。其性能可靠,便于在工作状态下维修或更换元器件,具有广泛的实用性。

This paper presents an intelligent Multi-Function Switch used in dig working face of coal mine, which be constituted by the main electric circuit and the control electric circuit. The main electric circuit and the control electric circuit is two sets symmetry forms, the control electric circuit takes PLC as core, two sets system is a mutually catena, two sets power supply different power supplies. So, whichever the set of the main electric circuit or the control electric circuit appears a problem; another would be automatic or manual work to insure the dig working face of coal mine has the breeze machine operation. It has credible function. It is easy for us to maintain or replace spare parts when it is working. The intelligent Multi-Function Switch has extensive function.
