The DC high voltage generator has over-current, over-voltage, zero-voltage start and fault protection functions. The over-current and over-voltage protection settings are relatively complete. If necessary, an audible and visual alarm can be performed to ensure that the potentiometer is reset to zero before each boost; In addition, you can also set its voltage protection value and visually display the set voltage.

The output current and voltage values of the DC high voltage generator are displayed together with the digital code, so that the operator can read the output status, and the operator can monitor the output status.

The DC high voltage generator can smoothly adjust the output voltage in the entire range, and can be converted to about 75% voltage output at any time, and the voltage conversion is about 0.75 times, which provides convenience for testing the zinc oxide arrester. In addition, when using a discharge rod, the output voltage will not be affected. The output voltage can also be timed, and it can work for about 30 minutes even under full load.

The boosting method of high frequency DC high voltage generator without pressure doubler:

How to boost the pressure doubler cylinder is built-in, as long as the power cord, cable and grounding wire are connected.

How to use the current-limiting resistor for boosting voltage without multiplier:

When conducting cable test, one end of the current-limiting resistor is connected to the upper end of the double pressure cylinder, and the other end of the current-limiting resistor is connected to a microampere meter. Note that the current-limiting resistor can only be used for capacitive load test (including cable test) Installation and use, do not need to be used in other tests.

The DC high voltage generator converts 220V AC power into DC high voltage, and then uses DC high voltage for field test. Therefore, the DC high-voltage generator can also be called an instantaneous high-voltage power supply. It is worth noting that this high-pressure continuous working time cannot exceed 30 minutes (national standard), which will cause serious damage to the instrument for more than 30 minutes.
