Use high frequency DC high voltage generator should pay attention to what problems?

The high-frequency DC high voltage generator adopts pulse width modulation (PWM) technology, IGBT, and advanced electronic circuits and components, and has output protection from grid fluctuations, zero-position, over-current, breakdown, over-voltage and other protection measures. Overcurrent, breakdown, and overvoltage protection circuits can be quickly operated to effectively protect equipment and personnel. Its output uses liquid crystal display, its volume and weight are lighter than the original KGF type, and it is very suitable for field use.

Use cautions:

1. The user must press 168 of the "Safety Regulations" and install two obvious disconnection points before the working power enters the tester. When changing the test sample and wiring, the two power disconnect points should be disconnected first.

2, the use of high-frequency DC high voltage generator staff, must have a "high-pressure test license" professionals.

3. Discharge the large capacitance sample by applying PSZGF special discharge resistance rod to discharge the sample. Discharge rod can not be immediately exposed to the sample, should first gradually close the discharge rod sample, to a certain distance air gap began to discharge, there is a hum, when there is no sound discharge rod discharge, and finally directly connected to the ground Discharge.

4. Before the test, please check whether all the test wiring, control box, double pressure tube and the ground wire of the sample are connected. The test circuit grounding wire should be grounded according to the requirements of this instrument manual.

5. When the DC high voltage is 200KV and above, although the tester wears insulated shoes and is located at a safe distance, due to the influence of the high voltage DC ion space electric field distribution printing, several nearby DCs may have different direct currents. Bit. The test personnel should not shake hands or touch the grounding body by hand, otherwise there will be a slight electric shock phenomenon. This phenomenon is more obvious in dry areas and winter, but due to the small energy, it will not cause harm to the human body.

6, PSZGF series high frequency DC high voltage generator control box power supply AC AC220V ± 10%, 50Hz. If the power supply is isolated by 1/1 or if spontaneous power is used in the field, the power supply must be connected to earth ground.
