High-voltage signal generator manufacturers Are high-voltage generators the same as electrostatic generators? The high-voltage power supply of the electrostatic generator alone cannot generate ion wind. It needs to ionize the surrounding controller through the needle tip on the electrostatic rod to generate positive and negative ions, so that there will be an ion wind. Is the high-voltage signal generator manufacturer the same as the electrostatic generator? ? The high-voltage power supply of the electrostatic generator alone cannot generate ion wind. It needs to ionize the surrounding controller through the needle tip on the electrostatic rod to generate positive and negative ions, so that there will be an ion wind. This wind is very fine. If you want wind, you need to Adding compressed air to the electrostatic rod, the high-voltage electrostatic generator can form an ion wind high-voltage discharge ozone generator. The high-voltage discharge ozone generator is a method that imitates the natural lightning to generate ozone. Corona is generated in the gas through an artificial alternating high-voltage electric field. The free high-energy ions in the corona dissociate the O2 molecule, which is aggregated into O3 molecule by collision. This kind of ozone generator has the advantages of mature technology, stable operation, long service life and large ozone output, so it is the most widely used ozone generator in related industries at home and abroad. The high-voltage pulse generator determines the withstand voltage of the oscillator tube according to the supply voltage, and determines the power of the oscillator tube according to the magnitude of the output current.
What should be paid attention to when using a high voltage generator? 1. During the cable withstand voltage test, the boosting process should be uniform and slow, and the depressurizing process should also be uniform and slow. At the same time, a protective water resistance should be added to the high-voltage output end. Otherwise, the reverse voltage may damage the instrument. 2. When the instrument is tested, the grounding must be good, and the grounding grid or ground pile should be selected, and the test cannot be performed without grounding.
Safety Warning 1. The staff who use the DC high voltage generator must have“High voltage test employment certificate”of professionals. 2. When using this instrument, the user must comply with the provisions of Article 168 of the Electric Power Safety Regulation, and install two obvious disconnect points before the working power enters the tester. When replacing the test sample and wiring, the two power disconnect points should be clearly disconnected first.
3. Before the test, please check whether all the test wiring, control box, pressure multiplier and the ground wire of the test product are well connected. The ground wire of the test circuit should be grounded at one point as shown in this manual. 4. For the discharge of the large capacitance test product, use the ZS special discharge resistance rod to discharge the test product.
When discharging, the discharge rod should not be in contact with the test sample immediately. The discharge rod should be gradually approached to the test sample, and the free discharge will start in the air gap at a certain distance. There is a hissing sound. When there is no sound, the discharge rod can be discharged, and then directly connect to the ground wire. discharge. 5. When the DC high voltage is 200kV and above, although the tester wears insulating shoes and is outside the safe distance, due to the influence of the high-voltage DC ion space electric field distribution, several nearby human bodies will have different DC currents. bit. The test personnel should not shake hands with each other or touch the grounding body with their hands, otherwise there will be a slight electric shock, which is more obvious in dry areas and winter, but generally does not cause harm to the human body due to the low energy.
6. The power supply of the portable ultra-light DC high voltage generator control box is AC 220V±10%, 50Hz. If the power supply is 1/1 isolated or used on-site with spontaneous power supply, the power supply must be artificially connected to the ground at one point. The above contents are the matters that should be paid attention to when using the high voltage generator.
