ZKZ-3S type speed monitoring device display the actual value of
speed, speed percentage, generator frequency
ZKZ-3S type speed monitoring device is connected with a tooth disc
pulse sensor and voltage transformer signal, speed monitoring unit,
the instrument can display the actual value of speed, speed
percentage, generator frequency and other parameters, the output of
the 12 switch and 1 - channel analog instrument. Only node voltage
transformer signal, the residual pressure by way of measuring the
frequency, speed monitoring 1 road junction, meter pulse signal and
the signal voltage transformer, through the gear plate residual
voltage measurement, monitoring speed meter node 2 way pulse signal
and the voltage transformer signal based on the pulse sensor probe
installation position can be set or the conventional monitoring of
pumped storage units (pump turbine), routine monitoring unit, 2 the
probe installed in any of 2 teeth in the center, while collecting 3
meter input signal, according to the calculation principle of 3 2
were monitored, with high reliability, monitoring of pumped storage
units (pump turbine), 2 probe strictly according to figure 5 As
shown in the installation, the instrument carries out a logical
judgment of the 2 probe positions to identify the positive axis
reversal of the unit.
