Functional
overview
This equipment is equipped with high voltage
pulse voltage divider, collecting high frequency and power
frequency voltage signal, mainly used for lightning wave
measurement, power system overvoltage (operating over voltage,
ferromagnetic resonance overvoltage, series resonant overvoltage,
etc.) and the system Frequency voltage.
The high voltage pulse divider will serve as
a front-end component of the overvoltage on-line monitoring system,
providing the relevant attenuator and connected to the overvoltage
on-line monitoring system via a dedicated shielded cable for system
overvoltage monitoring.
1. a high
voltage side
A) a high voltage side of the installation:
from the high voltage power grid bus access to the high voltage
side of the high voltage arrester and with the high side of the
high voltage side of the voltage divider to complete a high voltage
side of the installation. The voltage divider is single phase,
divided into A, B, C phase, single phase direct
connection.
B) can collect high frequency and frequency
of the voltage signal.
2. Secondary,
measurement monitoring side:
A) secondary monitoring side wiring: the
supplier is equipped with a good voltage divider measurement output
interface connector, the supplier should be equipped with
attenuator interface connector, the middle is connected to the
demand side of the measurement cable signal The attenuator of the
line and the supplier forms the measurement loop. Intermediate
connection of the measurement cable signal line must be armored
flame retardant tape with the measurement cable signal line:
coaxial *****1 or *****2 RF shielding cable. Anti-interference
ability of the best. Secondary regulator side of the voltage
divider Output port connector: Yes SL*6 connector.
Coaxial.
B) The voltage output of the secondary side
of the voltage divider is **0V, and the voltage to the data
acquisition mechanism is *0V. The buffer (attenuator) needs to be
installed.
C) Secondary output range: depending on the
ratio of the partial pressure ratio. Ratio of large voltage is low,
the ratio of small voltage high.
