The invention relates to an anti-interference parameter
integration testing device for an ultra-
high voltage line. The anti-interference parameter
integration testing device is used for performing integrated measurement on
power frequency parameters of a measured ultra-
high voltage line. The device comprises a
pilot frequency measurement module, a measuring and wiring automatic switching module, a series and parallel impedance suppression module and an opposite-end GPS synchronous measurement module. The
pilot frequency measurement module is used for performing digital separation and
power frequency parameter calculation of a
power frequency interference
signal and a
pilot frequency
signal on a measured
signal. The measuring and wiring automatic switching module is connected with the pilot frequency measurement module and used for automatically switching internal wiring
modes according to the power frequency parameters to be measured. The measuring and wiring automatic switching module and the measured ultra-
high voltage line are respectively connected with the series and parallel impedance suppression module which is used for relieving the influence on measurement by
electrostatic induction voltage and induced current. The opposite-end GPS synchronous measurement module is connected with the measured ultra-high
voltage line and is used for synchronously performing measurement of the
physical quantity of the line at the other end of the measured ultra-high
voltage line by means of GPS synchronization. Compared with the prior art, the anti-interference parameter
integration testing device has the advantages that the device is of
modular design, wiring is easy, and all tests can be completed as long as wiring is performed at a time.
