K3030

Introductionú¦ 1. Advanced SCM control system enables K3030 system to run steadily. 2. Simple internal design also contributes to steady system running 3. 1448 points waveform fitting is for every cycle, reaching the leading position at home, as has significantly improved the amplitude-frequency Characteristic and voltage-current transient/instantaneous response for the system, with the current transient response of 20 ª¦s. And the transient voltage response of 30 ª¦s, obviously exceeds the China national standard (200 ª¦s). Excellent transient response can be more suitable for the development trend of the new rapid digital type protection relay. 4. 20-digit serial D/A Converter is adopted, and the serial D/A Converter has better linearity and precision than the parallel D/A, greatly increasing the precision of voltage and current signal. 5. 40-220V/0.6A auxiliary DC power supply is under control of software, the power supply can individually provide working power to the protection device or other equipments. Ripple coefficient is less than 0.1% and accuracy is 0.5% Remarkú¦ 1.During the test, amplitude value, phase and frequency are continuously and arbitrarily adjustable with simple operation. Be able to test various types of AC/DC voltage relay, AC/DC current relay, frequency relay, power relay, impedance relay, harmonic relay, differential relay and synchronism relay about operate time and operate value by manual or by machine;Faults-Simulation enables users to calibrate fixed values of distance protection device and zero-sequence protection device. And fault simulations also lead to distance relay test of distance protection device and zero-sequence protection device. And K3066 can auto-scan the ratio restraint curve of differential protection in microcomputer and digital transformer as well as Generator-transformer Set. 2.The installation of particular heating radiator contributes to the reliable practicability of K3030.There are four high-power ventilating fans inside the Host. Thermal-shutdown is adopted to ensure the excellent stability & reliability of the amplifier even under long-playing working state along with high current. Current generator provides the function of open-circuit protection and open-circuit alert in itself. While Voltage generator possesses the functions of short-circuit protection, of output testing against waveform distortion, of Auto-recognition & Auto-alarming & Self-lock protection against misconnecting as well as the function of Dynamic Waveform Monitor&Display.. 3.Possess isolated input contacts, and the same case for idle contacts and electric potential contacts; and well adapt to various wiring installation. 4.Four voltage output channel, of which one channel is set as auxiliary DC supply by software, making it more convenient for field debugging. 5.Internal design is of architectural style framework and of shock & impact resistance external box made of high intensity aluminum alloy enables the equipment subject to rigid vibration 6.Be able to work as DC generator to provide Relay Protection Device with DC Voltage Generator(0í¡220V) 7.Direct edition on test report when using PC, and that scanning graph can be added into test report is useful for report analysis.
