Xu Ji WFB-813A, WBH-817C, WFB-814 and WBH-818C/L

Xuji WFB-813A microcomputer generator protection measurement and control device
Application range WFB-810 transformer group protection device is mainly suitable for electric power
Transmission protection of 20MW-100MW wiring.
WFB-811 unit integrates the full protection of a generator, WFB-812 unit integrates the full electrical protection of a main transformer, WFB-813 unit integrates the full electrical protection of a high plant transformer and excitation transformer (exciter), non-power protection still borrows WFB-804 or WBH-814 unit.
WFB-810 microcomputer transformer group protection device can meet the configuration requirements of small and medium-sized transformer group, reasonable separate main and backup protection and independent non-power protection.At the same time, the series of protection can also be directly connected to the power plant's integrated automation system.
Note: All the secondary wiring of the TA is connected to the "Y" type.

1.2 Functional Features
l High-performance hardware: 32-bit high-performance DSP processor, 32-bit logic processor and 16-bit high-speed serial port A / D; strong and weak separation, with high self-inspection function to ensure high reliability of hardware.
l Real-time multi-task operation platform: adopt Nucleus Plus real-time multi-task operating system to ensure the software
Operational stability.
Separate CPU operation mode after l main: The protection device adopts dual power supply and dual CPU operation mode.One of the CPU
Complete the main protection function of one object, the other CPU completes the backup protection function of one object, and is independent of each other, separate power supply, and can work independently and exercise its corresponding protection function.
l Powerful communication function: information and message can be uploaded, recording data compatible with COMTRADE format; communication interface
Strong tolerance, openness, support for IEC60870-5-103 communication regulations.
The l can achieve the " double main single after, the main backup protection
Separate " protection configuration requirements;
Non-power type protection is independent of electrical power
Quantity protection, to meet the relevant requirements of "counter-measures".
Online modification of l trip mode: the trip mode after each protection action, the user can adjust itself without modifying the protection secondary circuit wiring; trip contacts can be directly connected to the circuit breaker trip circuit.
The l-friendly man-machine interface: large screen, graphics, Chinese, color LCD, can also be operated through the PC.
The l provides the wave recording function and the perfect waveform analysis software
The protection device can record the waveform of 4 cycles before and 6 cycles after the action;
Data and information can be printed locally or through a network printer to facilitate the fault analysis after the accident;
Provides offline waveform analysis software that can reproduce fault trends.
l Perfect event recording function: protection action report, switch volume change, self-inspection results, fixed value change, and wave recording data are all recorded, which can be printed and summoned in real time.
