Product Description
Product Description1.Description
WDR-821C microcomputer capacitor protection and monitoring device (hereinafter referred to as device) is applicable to protection and monitoring of parallel capacitor of 35kV and lower voltage classes. Protection function design of this device is based on visualization logic development (VLD) environment developed by XJ, meanwhile adopts layering and modeling design philosophy to realize partition of protection function based on data processing, element calculation, protection logic and exit logic.2.Features- Adopt "VLD" visual tool with independent property right by XJ, featuring high software reliability.
- Possess offline logic simulation function, to realize "transparency" of accident analysis.
- The totally-sealed cabinet is adopted for the device, featuring in strict separation of strong and weak current, strong anti-interference capacity, as well as overall self-inspection of hardware loop.
- 2 Ethernet ports are configured to support IEC 61850 communication protocols.
- Time hack: support SNTP time hack, B code time hack, GPS pulse time hack and 1588 time hack.
- Thorough event recording function, storage of records up to 80 latest event reports, with action report records of no less than 100, and report record of current and voltage of 750ms.
- Feature in friendly man-machine interface, full-Chinese Windows menu mode, clear structure and convenient usage.
- Complete protection function, which is able to realize the adaption of protection function through configuration tool to meet the personalized requirements of client.
- Flexible operating circuit configuration, applicable to various operating structures.
