On-load voltage regulating switch/tap changer · Product code P-167

The KDKC transformer on-load tap-changer tester is designed according to the high-voltage testing equipment of the power industry standard of the People's Republic of China and the general technical conditions DL/T846, 8-2004. It can meet the requirements of the "Power Equipment Handover and Preventive Test Regulations", which require checking the action sequence of the on-load tap-changer and measuring the switching time. It can accurately measure the transition time, transition waveform, transition resistance, three-phase periodicity and other parameters of the on-load tap-changer. It is a commonly used equipment for testing on-load tap-changers. Technical parameters: Three-phase constant current source charging, charging current: 3A/1A gear; 0.6A/0.2A gear Maximum port voltage: 24V Maximum transition resistance range: 100Ω Transition resistance measurement range: 1A gear: 0.4Ω～20Ω 0.2A gear: 10Ω～100Ω Waveform recording time length: 300ms Sampling rate: 30k Time resolution: 0.1ms Resistance resolution: 0.1Ω Accuracy: Transition resistance: ±5% of reading ±0.1Ω Transition time: ±0.5% of reading ±0.2mS Operating temperature: -10～40℃ Operating relative humidity: <85%RH Product nickname: Transformer on-load voltage regulator switch tester Transformer on-load tap changer tester Transformer transition resistance tester Main features: Test Y0 Y△ type transformer, the resistance value is displayed directly without conversion; The data analysis is user-friendly, and faults in the middle of the waveform can be automatically found and marked; the waveform display automatically adjusts the resistance value and time amplitude according to the sampled data; the △-type transformer can display three-phase periodicity; it can be tested with or without windings; the four-terminal wiring method provides high-precision resistance measurement without wire compensation; continuous testing can be performed during the test, saving the time of transformer power outage; the instrument can save word reports to facilitate data management and query; The instrument is controlled by a small computer, equipped with an 800×480 color LCD touch screen, a high-speed printer, and supports an external mouse, making it easy to operate; the instrument can automatically save 1,000 sets of data internally, or it can be saved via an external USB flash drive.
