Diesel engine generator set protection device
Diesel generator differential protection device is composed of a high degree of integration, bus no chip, high precision current voltage transformer, high dielectric strength, high reliable intermediate relay switching power supply module.
Differential protection device
(1) the variety is complete: differential protection device, a variety of special complete, can meet the various types of substation equipment, a variety of protection requirements, this
The earliest diesel engine in the world
The earliest diesel engine in the world
It provides a great convenience for the design of variable distribution power station and the computer network.
(2) the hardware adopts the latest chip to improve the advanced technology, using CPU 80C196KB, measuring 14 A/D conversion, the analog input circuit 24, collected data processing using DSP signal processing chip, using high-speed Fourier transform to get the fundamental harmonic wave of 8, special automatic correction software, ensure the high precision measurement. Using dual port RAM and CPU transform data, it constitutes a multi CPU system, communication using CAN bus. With high communication rate (up to 100MHZ, generally run in 80 or 60MHZ) anti interference ability and other characteristics. Through the keyboard and liquid crystal display unit can be easily carried out on-site observation and a variety of protection methods and the setting of protection parameters.
