RCS-9000CS series protection and measurement device is a new "four in one" comprehensive protection and measurement device for enterprise power system
The device is suitable for petrochemical, iron and steel, metallurgy and other industries, as well as for the power industry, which requires flexible protection functions
Living occasions.
RCS-9000CS series protection, measurement and control device adopts advanced technology and careful design, so that the protection and measurement and control are in phase
For separate and integrated protection devices, the operation of the protection device is not affected by measurement and control and external communication to ensure the safety and reliability of the protection
Dependability. RCS-9000CS series protection, measurement and control device not only supports the protection, monitoring and control functions required on site, but also supports
With various advanced application functions required by integrated automation, such as fault information, wave recording information, etc., it is an enterprise power system
The security, stability and economic operation of the system provide a solid foundation.
two . Main features
The device adopts a fully enclosed cabinet, which strictly separates the strong and weak current, cancels the traditional backplane wiring mode, and
Corresponding anti-interference measures have also been taken to greatly improve the anti-interference capability of the device, and the external electromagnetic radiation also meets relevant requirements
Standards.
Rich hardware resources, with 25 input channels, provide abundant signals and outlet contacts, and support outlet plug-in expansion.
The outlet configuration function is supported. Each protection element can flexibly select the operating outlet, which facilitates the field application and connection
Implementation of lock logic.
The operating circuit is flexible in configuration and can adapt to various operating mechanisms.
The protection function configuration is complete, the action is fast, and the performance is reliable.
In addition to the conventional protection function, the motor protection also has a more complete auxiliary control function: starting time
Isolation control function, start report recording function (record the starting time of the motor, large current and large differential current during the starting process,
And can record the starting waveform), low-voltage locking starting function, motor starting interlocking logic control function, large current locking function
Can wait.
In addition to current protection, line protection also provides voltage protection, which is applicable to incoming line, buscouple and various feeder units
Protection of.
It has perfect device testing function, which facilitates on-site debugging and testing.
The device has software timing and hardware timing functions. Hardware timing supports GPS differential second pulse timing or IRIG-B
The device can automatically identify the time synchronization mode.
Most devices can support remote opening and closing of three-way switch.
Perfect event report processing function, which can save 64 new action reports and 256 new SOE displacement records
Report, newer 64 user operation record reports, newer 16 motor startup record reports, more 8 fault recording
Report (the recording time of each fault is longer than 15 seconds).
The protection function and communication function are realized by separate CPU, and the network condition does not affect the normal operation of the protection.
Friendly man-machine interface, Chinese character display, Chinese report display and printing.
Flexible background communication mode, equipped with Ethernet communication interface (optional Cat 5 line or optical fiber).
Multiple independent Ethernet interfaces (two in standard configuration; three at most), with independent channels and high reliability,
It can simultaneously support the monitoring background in the station, protect the information workstation, and dispatch communication. It supports two separate 485 ports for communication.
Support the communication protocol of power industry standard DL/T667-1999 (IEC60870-5-103 standard).
It meets the requirements of DL/T 478-2001 General Technical Conditions for Static Relay Protection and Automatic Safety Devices.
Comply with the requirements of GB 14285-93 Technical Code for Relay Protection and Safety Automatic Devices.
