The correct way to use the DC high-voltage generator Although the test personnel wear insulated shoes, the DC high-voltage generator is 200kV and above. And it is in an area beyond the safe distance, but due to the influence of the high-voltage direct current ion spatial electric field distribution, several adjacent human bodies will have different direct current potentials. 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. This phenomenon is more obvious in dry areas and winter, but due to the low energy, it will generally not cause harm to the human body.

And install two obvious disconnection points before the working power supply enters the tester. When replacing the test product and wiring, first use the instrument, please follow the electrical safety regulations. The two power disconnect points should be clearly disconnected first.

One point is grounded. Before the test, please check whether the grounding wires of all test wiring, control box, pressure doubler and test product are well connected. The grounding wire of the test circuit should be as shown in this manual.

The discharge rod should be gradually approached to the test product first, and the ZS special discharge resistance rod should be used to discharge the test product for the discharge of the large capacitor test product. When discharging, the discharge rod should not be brought into contact with the sample immediately. A certain distance from the air gap begins to discharge freely, there is a hissing sound, when there is no sound, the discharge rod can be used to discharge, and finally the ground wire is directly connected to discharge.

It is necessary to artificially connect the power supply to the earth. The power supply of the Rx series DC high voltage generator control box is AC, if the power supply is changed by 1/1 isolation or the spontaneous power supply is used on site.
