产品简介
Three phase transformer winding deformation tester, transformer winding deformation comprehensive testing device, Bluetooth winding deformation tester
Hua Bao brａnd HB-BRB3 transformer winding deformation comprehensive tester uses the principle of microcomputer control to test the USB connection between the host computer and the main control computer. It can be tested without hanging the cover or disassembling the transformer. At present, it uses the most popular double sweep method to measure. The analysis software is powerful, simple in wiring, convenient in use, accurate and reliable in testing. It is an electric power Recommended products.
HB-BRB3, ： QQ：
1. Acquisition and control using high-speed, highly integrated microprocessor.
2. Communication USB interface used between a laptop and instrument.
3. Wireless WIFI interface (optional) used between the laptop computer and instrument.
4. Hardware adopts dedicated DDS digital high-speed scanning technology (USA), which can accurately diagnose the faults like winding distorted, bulged, shift, tilt, inter-turn short-circuit deformation and inter-phase contact short-circuit.
5. High-speed dual-channel 16-bit A/D sampling (in field test, move tap changer, and the wave curve shows obvious change) .
6. Signal output amplitude is adjusted by software, and the peak value of amplitude is ± 10V.
7. The computer will automatically analyze the test results and generate electronic documents (Word)
8. The instrument has dual measurement features: linear frequency scanning measurement and segment frequency scanning measurement, compatible with measurement mode of two technical groups in China
9. The amplitude-frequency characteristics are in line with the national technical specifications on amplitude-frequency characteristics tester. X-coordinate (frequency) has linear indexing and logarithmic indexing, so you can print out the curve with linear indexing and logarithmic indexing. The user can choose either according to actual needs.
10. Automatic test data analysis system,
Compare between A, B, C -phases in winding similarity comparison, and
the analysis results are:
① excellent consistency
② good consistency
③ poor consistency
④ rather poor consistency
Compare winding deformation by calling the original data and comparing it with the current data of the same phase, namely A-A, B-B, C-C, and the analysis results are:
① normal winding
② mild deformation
③ moderate deformation
④ severely deformation
11. Word electronic document can be automatically generated for saving and printing.
