ZDL-Y axis power monitoring device to monitor the unit shaft voltage and shaft current

Input signal : Assembly shaft voltage 1 way

Signal frequency feedback 30- 250HZ

Analog output : 6 way 4-20mA output

Size: 330X179X462 mm

Turbine generator shaft voltage generated during operation due to the stator magnetic field unbalance is inevitable, when the voltage is too large or damaged insulation when the shafting shaft voltage will cause a large axial current, shaft voltage, current will destroy the stability of the shaft bearing oil film and the surface of the bearing and shaft neck burns, until the cause bearing damage, ZDLY axis power monitoring device while monitoring the generator shaft voltage and bearing current, when the measured value exceeds the limit of mutation, sends out the alarm signal to ensure the safe operation of the unit. The shaft voltage preamplifier, shaft current signal acquisition board adopts digital signal processing technology with FPGA as the core, the Fu Liye transform of the original signal. To calculate the real value of fundamental and harmonic components of the core process control using SiemensS7 200 PLC control, ensure reliable operation of the device, the redundant input and output, which is the ARM color touch Screen intuitive, beautiful, simple a little, but also with buttons, LED digital display window stability, reliability.
ZDL-Y axis power monitoring device to monitor the unit shaft voltage and shaft current, when the measured value exceeded the mutation, issued an alarm signal to ensure unit safety
