ZY-PDM1000U-G GIS / ZY-PDM1000U-T transformer UHF partial discharge online monitoring system
ZY-PDM1000U-G GIS UHF partial discharge online monitoring system consists of internal and external UHF sensors, signal processing unit, high-speed data acquisition and conversion unit, and background analysis software.
1 Record the basic characteristic parameters of partial discharge such as amplitude, phase and frequency of partial discharge signal. Record the change trend of discharge amplitude and frequency, phase synchronization can choose internal synchronization or external synchronization;
2 Record discharge characteristic spectra such as partial discharge phase distribution map (PRPD), pulse sequence phase distribution map (PRPS), phase-amplitude map, discharge amplitude, and discharge frequency trend chart;
3 The system can automatically identify typical partial discharges in GIS (free metal particle discharge, floating potential body discharge, creeping discharge, internal air gap discharge of insulators, metal tip discharge, etc.);
4 The system test data can be connected to the background system of the protection manufacturer, which can be customized and developed according to the requirements of different manufacturers;
6 The software system is easy to operate and powerful;
5 standard case (4U height), flexible installation position, can be installed in the HSB cabinet, indoor and outdoor separate case. Plug-in acquisition card design, flexible configuration and optional channel number, easy to expand.
1 High-gain design, gain up to 40db, out-of-band suppression -40db; FPGA-based high-speed data acquisition system, sampling frequency up to 125MS / S.
2 PRPS map display adopts adjustable display angle design, which can display 3D map from various angles; PRPD map shows data accumulation and adjustable amplitude, which is convenient for diagnosis and analysis; hierarchical alarm settings, the same alarm signal will not repeat the alarm;
3 The data can be connected to the relay protection system of the manufacturer, which meets the IEC61850 communication standard, which is convenient for maintenance personnel to operate.
