生产厂家安科瑞开关柜无线测温装置
ARTM-Pn无开关柜无线测温装置根据《NB/T 42086-2016无线测温装置技术要求》开发,可用于3~35kV户内开关柜,包括中置柜、手车柜、固定柜、环网柜等多种开关柜,也可用于0.4kV低压柜,包括固定柜,抽屉柜等。无线温度传感器可安装于柜内任何发热点上,利用无线数据传输技术,可实时把监测数据发送出去,通过ARTM-Pn无线测温采集装置就地显示温度,也可以通过装置的RS485接口互联组网实现远程智能监控。
接通符合要求的工作电源,装置即进入工作状态。
After connecting with suitable power source, the device will be worked.
装置提供四路开关量输入,可以将断路器的辅助接点接入。装置上电正常工作:输入接点闭合,开入状态界面显示该回路为1;输入接点断开,开入状态界面显示该回路为0。
The device provides 4 digital input, they can connect to the auxiliary contact of breaker. The device is worked after power on. If the digital input contact is closed, the DI is “1” on the DI Status interface. When the digital input contact is open, the DI is “0” on the DI Status interface.
自动定值越限继电器输出包括:无线温度传感器高温、超温、相间温差、温度突变。高温预警为第一路继电器输出,超温、相间温差、温度突变告警为第二路继电器输出。
Relay output include: high temperature, over temperature, alternate temperature,mutation temperature. The high temperature alarm is first relay output; the overmutation,alternate,temperature alarm is second relay output.
注意:需将相应的控制字选择为“投入”才有效!
Notice: it is valid only when the “Node Enable” of sensor group is “ON”!
装置通过无线温度收发器和各无线温度传感器直接进行温度值的传输,并采用液晶显示各无线温度传感器所测温度。通过菜单可设置无线温度传感器组的高温预警值、超温告警值、相间告警预警值、突变告警预警值,当测得温度值超出设定值时,装置继电器输出触点闭合。
The device transmits the temperature values directly via the wireless temperature coordinator and wireless temperature sensors and shows temperature values measured on the LCD screen by wireless temperature sensors. Set the high temperature values,over temperature values, alternate temperature values, mutation temperature values of wireless temperature sensor groups. When measured temperature values exceed the setting values, the relay output contact will be closed.
装置可以测量主回路的电流、电压、有功功率、无功功率、视在功率、功率因数、电能等电力参数,可在装置“电量”菜单中查看,通过左/右键切换显示内容。
Device can measure the current,voltage, active power, reactive power, apparent power, power factor,electric energy and other electric parameters of main circuit and check in the “electric quantity” menu of device. By left/right key switch display content.
电参数的显示均为一次侧值,用户需选择正确的信号接入方式及PT、CT变比,以便正确显示测量值。
The display of electric parameter is all primary side value and the user shall select correct signal access way and PT, CT no-load voltage ratio to correctly display the measured value.
