Fast delivery Product Introduction High voltage withstand test of electrical equipment is one of the most important items specified in insulation preventive test. The withstand voltage test can be divided into ac withstand voltage test and dc withstand voltage test. The ac withstand voltage test can be divided into power frequency, frequency conversion and 0.1 hz ultra-low frequency test technology, of which 0.1 hz ultra-low frequency technology is the latest technology recommended by the current international electrotechnical commission. It adopts 7-inch touch screen, the latest arm7 single chip microcomputer, high-speed ad acquisition circuit, and is equipped with background management software. It is especially suitable for withstand voltage test of electrical equipment with large insulation equivalent capacitance (such as power cable, power capacitor, large and medium-sized generator and motor, etc.), which conforms to the national standard of electric power industry, general technical conditions for ultra-low frequency and high voltage generator (d) newly issued in 2004 I /1849.4-2004. 4. Voltage positive, negative peak error: <3% 5. Voltage waveform distortion degree: <5% 6. Conditions of use: indoor, outdoor; temperature: -10°C~+40°C; humidity: <85%RH 7. Power supply fuse: See table 3 8. Power Supply: Voltage 220V±5%, 50±5Hz Note: If the portable generator is used for power supply, the generator output voltage and frequency are required to be stable (generally, the power is greater than 3kW, the frequency is 50Hz, and the voltage is 220V±5% 9. The electrical capacity of the subject shall not exceed the maximum rated electrical capacity of the instrument, and the value is shown in the table 3; •Advanced technology: digital frequency conversion technology, microcomputer control, pressure rise, pressure reduction, measurement, protection, etc •The test process is fully automated. • Easy to operate: simple wiring, fool operation. •Comprehensive protection: multiple protection (over-voltage protection, over- current protection at high and low voltage sides), rapid action (when acting) • Room < 10ms), the instrument is safe and reliable. •Safety and reliability: the controller is connected with the low voltage of the high voltage generator, with photoelectric control, safe and reliable use. •The high and low voltage closed-loop negative feedback control circuit is adopted, and the output has no capacity rise effect. •Complete configuration: capacitive touch screen, LCD Chinese character display, automatic storage, automatic printing. • Large test range: 0.1Hz, 0.05Hz and 0.02hz multi frequency selection, large test range. •Small volume and light weight: it is very convenient for outdoor operation. • Upper computer background management software (selective assembly)
