Power dry transformer material comprehensive analyzer/Winding coil material copper aluminum tester
Product overview
KDBR-CZ distribution transformer copper and aluminum quality discrimination tester (transformer material analyzer) is a multifunctional transformer comprehensive tester developed by our company, which is a combination of transformer winding copper and aluminum quality analysis, capacity measurement, no-load loss measurement, load loss measurement, DC resistance measurement, ratio, turn ratio measurement and transformer code level determination.
The instrument comes with high-efficiency rechargeable lithium battery, which can work without external power supply. The battery can be continuously measured 200 times when fully charged. The internal digital synthesis of three-phase standard sine wave signal, in the measurement of transformer capacity and transformer short-circuit loss without the need for external three-phase test power supply and voltage regulator, upflow and other auxiliary equipment, simplified wiring;
The six channels synchronous AC sampling and digital signal processing technology are used in the instrument, which successfully solves the problem of low power factor measurement and multi-channel signal synchronous measurement and calculation under the condition of mains power. At the same time, the voltage correction, current correction, temperature correction and waveform correction are introduced to automatically convert to the positive value of the rated state, which greatly improves the working efficiency.
The measuring instrument integrates the high and low winding copper and aluminum quality analysis and diagnosis system. By synthesizing the winding turns of the transformer and the body data of the transformer, the probability distribution model affecting the coil material of the transformer is established, the coil material analysis probability function is determined, and the coil copper and aluminum factors are calculated according to the transformer capacity, high and low coil turn ratio, packet height, packet thickness and other measured values. Accurately determine the material of the transformer coil.
The instrument has the advantages of small size, light weight, high measurement accuracy, good stability, simple wiring, convenient testing and recording, greatly improving the work efficiency, etc. It uses the LCD in the form of a large screen as a display window, the menu operation in the form of a picture and is equipped with electronic auxiliary functions such as Chinese characters, voice prompts, etc., the display interface sets multiple parameters in one screen, and the human-machine dialogue interface is friendly. Easy to use, fast, accurate and reliable data, display and record measurement data.

Function and characteristics
1. Winding material determination:
The instrument integrates the winding copper-aluminum quality analysis and diagnosis system, adopts the non-destructive testing method, and establishes the probability distribution model affecting the transformer coil material by synthesizing the transformer ratio data and the transformer body appearance data. According to the transformer capacity, high and low voltage coil turn ratio, packet height, packet thickness and other measurement values, The copper and aluminum parameters of the coil are calculated, so that the copper and aluminum quality of the transformer winding can be accurately analyzed and judged.
2. Measurement of capacity:
Instrument built-in rechargeable lithium battery, built-in three-phase pure sine wave inverter power supply, output voltage automatic regulation, with soft start, soft stop, overcurrent, low voltage protection function, no external power supply can achieve the power distribution transformer capacity measurement and model judgment, and display transformer impedance voltage and converted to rated temperature, rated current load loss.
3. Dc resistance test:
Integrated DC resistance measurement of small and medium-sized transformers and voltage transformers, the use of power technology, multiple current gears, wide measuring range, fast measuring speed, can automatically select the current according to the load, higher measuring accuracy.
4. Load loss measurement:
Display three-phase voltage, three-phase current, three-phase power, automatically calculate the transformer impedance voltage percentage, converted to rated temperature, rated current load loss, automatically determine the oil immersed or dry distribution transformer core model, the test process with alarm adaptive prompt function, convenient for on-site users to use.
5. No-load loss measurement:
The instrument displays three-phase voltage, three-phase current and three-phase power, automatically calculates the no-load loss of the transformer's no-load current converted to the rated voltage and corrected for waveform distortion, and displays the type of oil-immersed or dry-type distribution transformer core.
6. Single-phase power supply to achieve three-phase transformer no-load, load loss measurement:
Can be used to check the transformer single-phase defects or used in the field without three-phase power. The instrument can record the data of three single-phase measurements, and calculate the no-load current, no-load loss, impedance voltage and load loss of the transformer according to different connection modes.
7. The measurement range allowed by the instrument can be measured directly, beyond the measurement range can be external voltage, current transformer, the instrument can set the ratio of external voltage, current transformer, directly display the value of the applied voltage and current.
8. Ratio, turn ratio measurement: through the known auxiliary winding, fast and accurate measurement of transformer ratio and turn ratio.
9.7.0-inch, 800*480 resolution, 1200 ultra-high brightness, wide temperature, wide viewing Angle, clear visibility under the sun full touch industrial color LCD screen.
10. Ac/DC dual use, lithium battery power supply or 220V AC charger power supply adaptive.
11. Intelligent charge and discharge management, remaining power display, low power voice alarm, backlight automatic adjustment, save battery power.
12. Power-free clock and date display; Data storage is divided into local storage and flash disk storage, where the local storage can store 1000 test data, and the local storage can be transferred to the flash disk; Edit and print directly on the computer.
13. Micro embedded thermal printing function, fast and silent.
14. Intelligent human-computer interaction interface: with perfect electronic help, each operation has a wiring diagram and text description, intuitive and simple operation.
