JYR integrated machine winding deformation measuring instrument

Introduction

The transformer winding deformation tester is used to test the winding deformation of power transformers with voltage levels of 6kV and above, as well as other special purpose transformers. During the operation or transportation of power transformers, it is inevitable to encounter impacts or physical impacts. Under the strong electric force generated by short-circuit currents, the transformer windings may lose stability, leading to deformation phenomena such as local twisting, bulging, or displacement. This will seriously affect the industry standard DL/T911-2004. The frequency response analysis method is used to measure the winding deformation of transformers. By detecting the amplitude frequency response characteristics of each winding of the transformer and comparing the detection results longitudinally or transversely, the possible deformation of the transformer windings can be determined based on the degree.

Main technical features

1. The acquisition control adopts high-speed and highly integrated microprocessors
2. USB interface for communication between laptop and tester
3. Integrating high-speed microprocessors with measurement and testing instruments, there is no need to use a mobile computer on the measurement site
4The movement adopts DDS dedicated digital high-speed scanning technology (USA), which can accurately diagnose faults such as winding distortion, bulging, displacement, tilting, inter turn short circuit deformation, and phase to phase contact short circuit through testing

5. High speed dual channel 16 bit A/D sampling (on-site test changes tap changer, waveform curve shows obvious changes)
6. Signal output amplitude software adjustment, maximum peak amplitude ± 10V
7. The computer generates electronic documents (Word) of the detection results
8. Equipped with dual measurement system functions of linear sweep frequency measurement and segmented sweep frequency measurement, compatible with the measurement modes of two current domestic technology schools
9. The amplitude frequency characteristics comply with the technical specifications of the national amplitude frequency characteristic tester. The horizontal axis (frequency) has two types of linear and logarithmic divisions, so the printed curve can be either a linear or logarithmic division curve, and users can choose according to their actual needs
10. The automatic data analysis system is used to horizontally compare the winding similarity between phases A, B, and C. The analysis results are: ① good consistency, ② good consistency, ③ poor consistency, and ④ poor consistency
Longitudinal comparison of A-A, B-B, C-C retrieves the original data and compares the winding deformation with the current data in phase. The analysis results are: ① normal winding, ② mild deformation, ③ moderate deformation, ④ severe deformation. 11. It can automatically generate Word electronic documents for saving and printing
12. Complete the technical requirements to meet the power standard DL/T911-2004 "Frequency Response Analysis Method for Power Transformer Winding Deformation"
