Supply of load tap switch tester, transformer load tap tester, transformer load

Wuhan Wei Austrian three high Electrical Equipment Co., Ltd. - WAYZ-2011 models transformer load tap switch tester generous state: transformer on-load tap tester high voltage test equipment according to the Electric Power Industry Standard of the People's Republic of China General Technology conditions DL/T846 ,8-2004 design, to meet the "handover of power equipment and preventive tests Statutes, check load tap changer action sequence, the measurement switching time requirements. Can achieve the accurate measurement of the parameters of the on-load tap the transition time, transition waveform, transition resistance, such as three-phase over the same period, the test load tap-ideal equipment. Main features: ① test Y0 Y △-type transformers, resistance displayed directly without translation; ② data analysis humane, can automatically find the the waveform middle of failure, and marking; ③. Waveform display is back according to the sampling data automatically adjust the amplitude of the resistance and time; ④ with winding or without winding tested; ⑤. the four terminal wiring to provide high-precision resistance measurement, and without wire compensation; ⑥. continuous testing during the test, saving the the transformer blackout of time; ⑦. instrument can survive word report, to facilitate data management and query; otherwise. instrument is controlled by a small computer, external color LCD touch screen with 800 × 480 high-speed thermal printer support plug-in keyboard and mouse operation convenient; ⑨ inside the instrument can automatically save the 800 sets of data, can also be an external U disk save. Technical parameters: ① phase constant current source charging, charging current: 1A file; 0.2A file ② Port Maximum voltage: 24V ③ The maximum range of the transition resistance: 100Ω ④. The transition resistance measurement range: 1A file: 0.8Ω ~ 20Ω 0.2A file: 10Ω ~~ 100Ω ⑤ waveform record length of time: 300ms ⑥ Sampling rate: 20k ⑦ time resolution: 0.1ms ⑧ resistance Resolution: 0.1Ω ⑨ accuracy: the transition resistance: ± 5% of reading ± the 0.1Ω transition time: ± 1% of reading ± 0.2mS ⑩ Operating Temperature: -10 ~ 40 ℃ use relative humidity: <85% RH
