GTE-841 (2) Dijital Motor Koruma rölesi

Application
GTE-84X digital motor protection measurement and control device is applicable to 3KV ~ 10KV voltage in high-voltage asynchronous motor protection and control device for the same. Where GTE-841 is mainly applied to 2000kW following small asynchronous motor protection, measurement and control, the GTE-842 is mainly applied to 2000kW and above a large asynchronous motor for the differential protection function protection, measurement and control.

Main Features
A. 4U standard aluminum chassis, combination of plug-in structure, after the plug case, each
Functional module design alone, electricity are completely separated, strong anti-interference ability, convenient field maintenance;
B. CPU intelligent card design, open into the open plug-ins to achieve real-time complete self-test; Can be detected in each relay coil;
C. Plug-in based on CANBUS bus links between, reduce the connection between the connector plug, bad real time detection;
D. Double 32 computer systems, the redundant system; Protection function using the 32 bit floating-point DSP processor, program and data in the
Chip operation; Operation speed, high reliability;
E. Man-machine interface, network communication and other management functions by 32 ARM MCU, speed, on-chip memory capacity big, strong ability of network
Interface;
F. 16 AD sampling, high measuring precision; Weekly wave 48 sampling points, harmonic processing capability;
G. Protection module using computer assisted graphical interface design is convenient for the two series of products development and functional modifications, flexible, efficient engineering design;
H. Complete the circuit breaker control circuit is provided with a remote control, jump, closing,
Spring without stored energy blocking close function etc;
I. Use 192X64 monochrome graphic LCD, Chinese menu interface; The flexibility to choose double
Ethernet and double 485 interface;
J. Can save at least 500 report recent incidents and operation report;
K. User management module using real-time multitask operating system, network interface, tasks such as real-time;
L. Can store 10 sets of protection setting value, double value zone self-test and mutual combination, setting change safely and convenient.
M. Based on electric power industry standard DL / T667-1999 (IEC 60870-5-103) standard communication protocol, and convenient with microcomputer monitoring or protect management computer network communication.
