A 0.1 Hz, ultra-low frequency compression technology advantages
Ultra-low frequency insulation withstand voltage test is actually an alternative method of power frequency withstand voltage test. In large and medium-sized generator, motor, power cable, etc. Try to power frequency withstand voltage test, due to their insulating layer of large electric capacity, so you need to large capacity test transformer or resonant transformer. Such large equipment, not only heavy, cost is high, and the use is inconvenient. In order to solve this contradiction, internationally widely used to reduce the test frequency, which reduces the test power supply capacity method. From many years of theory and practice prove that both at home and abroad, with 0.1 Hz low frequency withstand voltage test alternative power frequency withstand voltage test, not only can have the same equivalence, and the volume of equipment greatly shrink ?
The company developed a new generation of "SVLF series 0.1 Hz low frequency high voltage generator" using the latest power electronic components and the latest ARM9 single-chip microcomputer technology, further reducing the volume and weight of the equipment, the fool operation, more stable performance, overcomes the short service life of the first generation of mechanical booster, the shortcomings of high failure rate, large volume. Through years of practice, a large number of user's feedback show that SVLF 0.1 Hz low frequency and high voltage technology in the leading, most valuable!
Second, SVLF series products technical parameters
1. The use of power supply: 220 v + 10%, 50 Hz - 5%
Note: if use portable generators for the generator output voltage and frequency stability (general requirements is greater than 3 kw power, frequency 50 hz, 220 v voltage + / - 5%), or to use some auxiliary measures to stabilize the generator output.
2. The precision of output voltage:
Peak output voltage instability degree: 1% or less
: the output voltage frequency instability are 3% or less
The output voltage waveform distortion rate: < 5%
3. Using the environment temperature - 10 ° C ~ + 40 ° C, humidity 85% RH or less
4. The test scope statement:
A. participants product instrument shall not exceed the rated capacitance electric capacity;
B. participants product capacity is too small, can affect the output waveform. If less than 0.05 (including F, the instrument will couldn't normal output, can be used at this time our company provide auxiliary device (optional)。
Three, product features
1. Advanced technology: using digital frequency conversion technology, microcomputer control, step-up, step-down, measurement, protection test process is fully automated.
2. Easy to operate, simple wiring, fool.
3. Protection of comprehensive, multiple protection (overvoltage protection, tilting high voltage and low current protection), action (action time 20 ms) or less quickly, safe and reliable instrument.
4. Safe and reliable: low pressure controller and the high voltage generator, photoelectric control, safe and reliable use.
