Introduction and application of device
HF-XBJK2000W wind power box-type substation intelligent monitoring device is used for analog quantity acquisition, non-electric quantity protection, electrical quantity protection, remote control and communication at high and low voltage side of wind power box-type substation, which can not only provide a separate box-type substation monitoring system for the power station, but also seamlessly access to the integrated automation system of the booster station. It realizes the remote management and automatic monitoring of box-type substation for the booster station, and meets the operation management requirements of "unattended operation and only a few persons on duty" for the wind power station.
Characteristics and advantages
● Rear plug-in/out mode, separation of strong and weak current.
● Being able to save total 400 recent event reports and operation reports of four groups.
● Adopt OLED graphic display with Chinese-English dual language.
● Input power supply for both AC and DC application.
● Wide temperature working environment of -40°C - 70°C.
● Switching of 8 sets of independent definite value.
Functional configuration
● Protection: Complete electric protection function of the two windings on the high and low voltage sides (differential current quick-break, percentage differential protection, differential current out-of-limit, three-section overcurrent, overload, zero sequence overcurrent, overvoltage, low voltage, TV disconnection, TA disconnection protection, high-voltage FC lockout protection), DC out-of-limit protection, and non-electric quantity protection.
● Measurement: 12-channel data acquisition of voltage and current, 6-channel data acquisition of direct current and 27-channel input data of remote communication signal at high and low voltage sides.
● Control: 6-channel standby relay outlet configuration (8-channel for optional)
● Communication: 2-channel 100Base-FX (optical port), 1-channel Ethernet communication interface (RJ45), a variety of communication protocols (IEC60870-5-103, 104 and TCP-Modbus, Mod-bus-RTU, DL/T645-1997, 2007) for 2-channel RS485 communication interface.

Application environment
● Ambient temperature: Operating: -40℃ - +70℃;
Storage: -45℃ - +85℃.
● Relative humidity: The monthly average maximum relative humidity of the wet month is 90%, and the monthly average minimum temperature is 25℃ and there is no condensation on the surface. When the MAX temperature is +40°C, the average MAX humidity exceeds 50%.
● Atmospheric pressure: 80kPa - 110kPa (relative altitude below 2km).
Notes
● Check whether the type, version number and electrical parameters conform to those of the ordering.
● Check whether plug-ins of the device are connected reliably, and whether the cables and rear terminals are fixed reliably.
● Strictly adjust and set the parameters according to the definite value list, and make sure that the protection items not in operation should be set as quit and confirmed.
● If any test has been conducted, clear all protection event records before the device is put into service.
