Design And Application Of Monitoring System For Power Safety In Coal Mine Underground

Based on the technical transformation project in Shaanxi Chenghe mineral companyWangcun mine underground power supply monitoring system for the background, introducesthe design idea and system designing of power supply monitoring system for underground,realises a underground-coal mine power monitoring system based on Industrial Ethernet ringnetwork using advanced computer control technology and network communicationtechnology.Shaanxi Chenghe mineral company Wangcun mine power supply is composed of two10kV110/35/10kV substation ground wire feeder to the central substation underground, and then bythe central substation feeder three substations and four substations, underground power supplyequipment with high, low voltage switch integrated function of the realization of local controland protection of the ground; the monitoring center can not understand the undergroundelectrical equipment running status and various electrical parameters.Frequent accidents in underground coal mine power supply, even cause the large areapower to stop the wind, lead to greater security risks. On the protection of underground powersupply system and control becomes more and more important. Therefore the grounddispatching command center and fast processing accident, reduce accidents, the security risksto a minimum, to achieve coal mine power network remote monitoring and automationmanagement ability.In the transformation of the underground power supply system, using the current domesticunderground industrial Ethernet ring network of underground power supply safety monitoringsystem based on advanced, using Ethernet to underground power supply monitoring stationand the ground control center to realize high-speed access, as a subsystem of the whole well integrated automation system, the production scheduling and command center groundmonitoring power supply equipment, remote control, telemetry, remote signaling under mine,remote adjustment, remote viewing function, thereby realizing no-man control in undergroundsubstation.
