The main technical features HNRB-Ⅱ transformer winding deformation tester HNRB-Ⅱ transformer winding deformation tester: l wrong transformer hanging hood, removable case can be tested. l l The instrument measured using the most popular method can sweep over 6kV transformer l measured using split structure, using a USB connection between the test host and the host computer, plug and play l field wiring simple to use l convenient measurement dynamic range is wide: -100dB ~ 20dB l powerful analysis software, software, hardware indicators meet the national standard DL / T911-2004 HNRB-Ⅱ winding deformation tester for testing 6kV and above power transformers and other special-purpose transformers, power transformers in operation or during transport will inevitably have to suffer the impact of various fault or short circuit current physical impact, in the role of a powerful electric power generated by the short circuit current transformer windings may lose stability, leading to local distortion, drum kits or displacement and other permanent deformation phenomenon, which will seriously affect the safe operation of the transformer. According to the national power industry standard DL / T911-2004 using winding deformation analysis method to measure the frequency response of the transformer, is amplitude-frequency response characteristics detected by each transformer windings, and the test results were vertical or horizontal comparison, according to the amplitude-frequency response characteristic changes degree of deformation is determined transformer winding may occur. HNRB-Ⅱ transformer winding deformation tester by measuring section and analysis software components, measuring part is the black box from the signal generation and signal measurement component, the analysis section completed by the laptop, connected via USB measurement part with a laptop, you can also wired or wireless Ethernet connection. HNRB-Ⅱ tester main technical indicators are: l test host and PC interface: USB interface. l per phase test takes only a minute. l Source: The instrument comes with a channel signal output as the sweep of the excitation signal; signal output as a standard sine wave output signal amplitude can be adjusted in software, the most significant ± 10V, the signal output impedance of 50Ω. l two acquisition channels, an excitation signal acquisition, an acquisition response signal for calculating a transfer function l measured excitation channel for a fixed range: ± 10V; response channel multiple ranges, the automatic adjustment during the measurement range, the maximum input signal for ± 25V l acquisition channel quantization precision: 12 l acquisition channel maximum static error: 0.5% l acquisition channel input impedance: 1MΩ l sweep measurement range: 1k-2MHz l scanning method: linear distribution measurement l scanning sweep Frequency accuracy: the accuracy of the signal source output frequency sinusoidal signal is not more than 0.01% l sweep measurement frequency: 1k-2MHz, measuring points to 2000 points l measuring range: -100dB ~ 20dB l Accuracy: ± 1dB (-100dB ~ 20dB) l l using Vittal original chassis power industry in line with national standards: DL / T911-2004 l Power: AC220V ± 10% (50Hz) l Ambient temperature: -15 ℃ ~ + 50 ℃ l Relative Humidity: 10% ~ 90% Product Address: http://www.whwghn.com/55/
