HKXB-600 Box Variable Measurement & Control Device

PRODUCT OVERVIEW

HKXB-600 box variable measurement and control device is used in new energy power stations(photovoltaic power stations,wind farms,etc),providing protection,measurement and control,protocol conversion,ring network communication and other functions for each on-site power generation unit,The device can be installed in a group screen or directly in a step-up box substation(non-direct grounding system or small resistance grounding system with voltage level of 35kv and below etc,) in the power generation unit.

KEY FEATURE

• It adopts high-performance 32-bit high-speed DSP monolithic digital signal processing controller as the main control unit
• The software and hardware are modular design,the hardware module adopts the internal LAN,and the design mode of the intelligent node can be flexibly configured,which greatly improves the reliability of the device
• High-speed floating-point arithmetic is used to greatly improve the measurement accuracy.The protection current measurement error is less than ±%,and the measurement current error is less than ±0.5%.
• The operation time is greater than 1000mS.The error is less than ±2%，the action time is less than 1000mS,and the error is less than ±20mS
• Full AC sampling and software digital filtering completely eliminate the influence of ero drift of the hardware circuit.
• The display module has a friendly man-machine interface,and all interface are displayed with needed languish,which is convenient to operate.
• All measured and parameters can be displayed in real time via the display module
• All critical data (system parameters,etc.) can be stored for more than ten years in the event of a power loss.
• Perfect accident record and self-inspection function,convenient for users to analyze the cause of the accident.It can record 100 protection action events,100 
• alarm events,and 100 displacement events.
• The device adopts fully sealted embedded structure,software and hardware redundancy design,perfect software and hardware self-test,strong anti-interference performance
• Easy debugging and maintenance,with friendly man-machine interface and right PC auxiliary software,convenient for device setup and debugging.
