KJ473煤矿局部通风机监控系统

 

产品用途

       KJ473煤矿局部通风机监控系统适用于煤矿井下有瓦斯、煤尘爆炸危险的环境。可对风机的运行状态自动进行监测。监测的参数包括:瓦斯浓度、风速等模拟量参数,馈电状态、软启动开停等开关量参数,并对所监测的运行状态参数实时集中显示;可形成电流、电压等参数的运行曲线。

 

产品特点

1、实现就地自动、就地手动、远控等多种控制方式;可实现“一键启动”、“故障风机自动切换”、“风量自动调节”等功能。

2、监测静压、风量、CH4浓度、电机定子温度、电机前后轴承温度、风机振动、电机电压、电机电流、有功功率、功率因数、累计电量等运行参数;监测显示各运行参数和设备运行状态。

3、采集现场实时数据,并实现历史数据查询,报警记录查询,提供实时趋势曲线、历史趋势曲线、运行报表。

4、提供多种通讯接口,可接入上级管理层(综合自动化平台),满足现场无人值守的要求。
