概述
CSC-237 multifunction motor protection IED supports IEC61850 standard communication and has interface which can connect with substation automation system and information management protection system; it provides the device description file (ICD file) that meets the requirements of IEC61850, and supports relative network services defined by IEC61850. It fully supports GOOSE functions to meet the needs of various configurations of the substation. It can be installed in the switchgear panel at site.
适用范围
CSC-237 multifunction motor protection IED is applicable for all kinds of neutral point indirect grounding systems below 10kV. It can be used as comprehensive protection for internal fault differential protection, phase-to-phase fault, overload and stalling of large and medium asynchronous motors (hundreds of kilowatts or more).
特点
①Integrated protection function and bay control unit function
②Meet three-phase trip requirement
③Equipped with module self-check function
④It provides complete report records, including operation report, alarm report and tripping report. Up to 2000 reports can be stored, and the reports can be saved, even there is a power outage
⑤It at most provides three electric/optical Ethernet ports, and communicates with substation automation system by choosing protocol IEC 61850 or IEC 60870-5-103 (TCP103).
⑥RS485 port are provided for communication with substation automation system through IEC60870-5-103 protocol.
⑦It supports PRP protocol based on IEC 62439-3, the device can be set to PRP mode, and the dual network ports adopt redundant mode to send and receive information in parallel.
⑧Simple network time protocol (SNTP), pulse, IRIG-B or 1588 synchronizing modes can be selected to time synchronization.
⑨It can be centrally installed in the switchgear panel or be installed on the switchgear indoors or outdoors.
