How to use high voltage generator and precautions for use How to use DC high voltage generator and precautions for use High voltage generator DC high voltage generator use method: DC high voltage generator is an instrument that provides high voltage DC source, and the instrument must be reliably grounded before using the instrument. Workers using DC high voltage generators must have“High voltage test employment certificate”of professionals.
When using the DC high voltage generator, the user must comply with the provisions of Article 168 of "Electric Power Safety Regulations 5261", 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. At the same time, there must be at least three staff on site, so as to effectively ensure the safety of users.
How to use the high-voltage generator and precautions for use What should you pay attention to when using the integrated DC high-voltage generator: During the test of the high-voltage generator, you need to connect the ground wire in advance, and the ground wire must be connected at any time. If there is no ground wire or ground grid, the experimental operation will be very dangerous. The personnel in the test operation must be qualified personnel with high-voltage test operation to carry out the experiment, and other untrained personnel cannot carry out such high-voltage experimental operation. Even the most basic step before is to check whether everything is in good condition, and whether all the wiring is complete, so that we can start our next experiment after confirming that it is correct.
In the laboratory use of high-voltage generators, although the test personnel will wear insulating shoes and may be in an area beyond a safe distance, because it affects the distribution of the DC ion space electric field under high voltage, it will cause the adjacent Several standing people carry different DC potentials. Therefore, when conducting high-voltage test operations, try to avoid the test personnel shaking hands with each other or touching the grounding body with their hands, otherwise there may be a slight electric shock. This phenomenon is particularly obvious in dry areas and winter, and it is not too much. If you really get an electric shock caused by such improper operation, you don't need to worry, because such electrical appliances are generally small and will not cause great harm to the human body. 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 will easily damage the instrument. When the instrument is tested, the grounding must be good, and the grounding grid or ground pile should be selected. Do not test without grounding. How to use the high-voltage generator and the precautions for using the high-voltage generator Shenzhen Noyafa Electronic Technology Co., Ltd.
