HRDC (HRBCD) transformer no-load load characteristic tester
| First, an overview of | ||
| HRDC(HRBCD)JB/T501-91GB1094-96, \\\\,0.2. HRDC (HRBCD) Load characteristics of transformer no-load tester in accordance with JB/T501-91 "Power Transformer Test Guidelines" and GB1094-96 "power transformer" technology standards that can simultaneously measure single or three phase AC voltage power transformer RMS, voltage, on average, RMS, active power, power factor and frequency of consumption parameters, measurement accuracy of 0.2. \, \, Intelligent, professional design, suitable for power transformer no-load, load test the test, is an ideal replacement of traditional products Analog Measuring Instruments | ||
| \ 2, the main features of | ||
| 1\240×128\,\\\\18. 1, using 240 × 128 dot-matrix liquid crystal display with blue backlight, Chinese operation menu, and also showed single-phase or three-phase voltage RMS, average voltage and current RMS, active power, power factor and frequency of 18 electric parameters. 2\, , , , P0\I0\Pkn\ekt\ek75℃\Zk. 2, multi-screen menu operation for the user to choose, easy to operate, and automatically calculate the various parameters, such as P0, I0, Pkn, ekt, ek75 ℃, Zk. 3\\. 3, can automatically voltage amplitude, waveform and temperature correction. 4\\, . 4, may be key to set voltage, current transformer ratio, directly display the primary measurement. 5\. 5, measurable, low-power factor range of power. 6\RS232, (). 6, with micro-printer and serial RS232 computer interface, print format, according to the standard record (character) format requirements. 7\, \,. 7, anti-jamming performance, strong, and reliable over-voltage, over-current protection for on-site verification environment. 8\. 8, may be an external voltage transformer and current transformer can be measured to broaden the scope of the instrument. | ||
| \ 3, the working principle | ||
| ,A/D,,,\\. The instrument adopts the high-end processor to process data, high-precision fast A / D converter, data collection using novel processing techniques, data processing using a fast way to use data processing, the equipment of these high-performance, high-precision, High reliability provided the necessary conditions mentioned. (240 × 128),,,,,. The instrument of man-machine interface using a large screen (240 × 128) full-graphics display of Chinese characters, menu strict grading, step by step guide you through the operation, you only need to boot, press any key, instruments, the menu will guide you through the You need to experiment. |
