Static Testing Equipment
Name：LFY-421 electrical insulation performance tester
Details
The main purposeIt is used to measure the insulation performance of electrical appliances, and measure the high voltage impact resistance, high voltage insulation resistance and high voltage breakdown time.
Technical characteristics
1. Use a dedicated high-voltage boost device to generate continuously adjustable AC high-voltage;
2. AC high voltage digital display, digital display of high voltage breakdown time;
3. It can be pressurized regularly, and the high voltage will be automatically closed when the time is up;
4. Instrument features 45HZ/55HZ inter-frequency power supply is used internally, which fundamentally solves the problem of on-site anti-interference;
5. Fully electronic voltage regulation, continuously adjustable output voltage;
6. The high-precision SF6 standard capacitor is attached, and the capacitor tgδ does not change with temperature, humidity, etc.;
7. The unique self-excitation method measures the fully sealed CVT, which can directly test the dielectric loss of C1 and C2;
8. Large screen (240×128) menu operation, brand new Chinese interface, very convenient to use;
9. With multiple protections, the instrument can quickly cut off the high voltage under high voltage short circuit, excitation, overvoltage, overcurrent and voltage fluctuations;
Technical index
1. Pressure range: 0-18KV±5%
2. Pressurization time: 0～9999.99s optional
3. Electrode area: Ф5mm;
5. Test data: voltage, current, breakdown time;
6. Power supply: single-phase 220V 50Hz 1KW
7. Weight: about 50kg
