JBS3330A microcomputer relay protection testing system
The main features
1, meet the field all test requirements. JBS3330A type has the standard four phase voltage, three phase current output, voltage 125 v/phase, the current 40 a/phase. Three phase parallel can amount to 120 a. JBS6630A type standard with six phase current, six phase voltage and output, current 30 a/phase, voltage 125 v/phase. Six phase parallel current can be up to 180 a. Can the traditional all kinds of relay and protection test, but also the modern all kinds of microcomputer protection all kinds of test, especially for transformer differential work protection and spare power automatic switch device, the test is more convenient and perfect.
2, all kinds of technical indices have all reached the issued by the power, the DL/T624-1997 "type microcomputer relay protection testing device technical conditions" standard.
3, single independent operation, with high performance of industrial computer, basic frequency 300 ~ 600 MHZ, memory 128 m, hard disk 6 ~ 12 g, running Windows XP operating system.
4, domestic industry first imported drawing stainless steel plate, stainless steel keyboard, at the same time, touch the mouse, overcome the track ball mouse operation not flexible, easy to damage faults, and choose 8.4 inch, resolution for 800 * 600 TFT truecolor screen, make whole single easy operation and durable.
5, master plate adopts the DSP + FPGA structure, 16 bit DAC output, the fundamental wave can produce every 2000 points of high density sine wave, has greatly improved the waveform quality, improve the accuracy of the tester.
6, power amplifier using high fidelity linear power amplifier, not only ensure the small current precision, and ensure the stability of the large current.
7, the USB interface directly and PC machine communications, without any tieline, convenient use.
8, can connect the notebook computer operation. Notebook computers and industrial PC using the same set of software, need not to study method of operation.
9, have GPS synchronous test function. Device can built-in GPS synchronous card (optional) through RS232 port and PC machine is linked together, to realize two table tester different for synchronous exchange test.
10, is equipped with independent special dc auxiliary source voltage output, output voltage respectively for 110 v (1 A), 220 v (0.6 A). To provide work for need to dc power relay or protection use.
11, with software self calibration function, avoid to open the case through the adjust potentiometer to calibration accuracy, thus greatly improving the precision of stability.
