Breakdown voltage tester Rubber breakdown voltage tester Insulation oil dielectric strength tester

Mainly suitable for testing the breakdown strength and withstand time of solid insulation materials such as plastics, films, resins, mica, ceramics, glass, insulation oil, insulation paint, cardboard and other media under power frequency voltage or DC voltage; The voltage breakdown tester is controlled by a computer, and the test curve can be observed online during the test process; Automatically store test conditions and test results data, and can access, display, and print them Technical parameters: 1. Input voltage AC220V 50Hz 2. Output voltage: AC: 0-50kV; DC：0～50kV 3、 Output power: 3kVA 4. Measurement range: AC: 0-50kV; DC：0～50kV 5、 Measurement error: ≤ 2% 6. Boosting rate: 1kV/s~3kV/s 7. Voltage endurance time: 0~4H 8. Leakage current 1~30mA can be freely set by computer software 9. Power supply AC 220V ± 10% single-phase AC voltage and 50Hz ± 1% frequency 10. Test environment temperature: 15~30 ℃, relative humidity: 0~85%, stable operation can be achieved. 11. External dimensions: length x width x height: 1000mm x 700 mm x 1300mm 12. Equipment weight: 150Kg (reference) 13. Grounding requirements: The instrument needs to be separately grounded, and the grounding should comply with standard requirements. The metal rod should be buried at least 1.5 meters deep underground

Performance characteristics: (1) Threshold protection: does not close the door, even if the power on point experiment starts, the device has no response, and the software has a prompt that the safety door is not closed. (2) Voltage zeroing protection: If there is a sudden power outage during the experiment, it will automatically return to zero position after the next power on, ensuring that the initial voltage is at zero position. (3) Termination voltage protection: The termination voltage can be set by software to ensure that if there is an abnormal rise to the specified voltage during the boosting process, it will automatically terminate and return to zero. Transformer exhaust port to ensure the good operation of the transformer, If there is any odor or burning or smoking phenomenon in the sample during the experiment, it can be eliminated through the exhaust system to increase its service life. (5) Independent grounding protection (6) Short circuit protection (7) Software misoperation protection (8) Leakage protection (9) End of experiment discharge protection
