Power Frequency High Voltage Generator Technical Features

1. Smaller size, lighter weight, more beautiful, more reliable, easy to operate, and complete functions, suitable for field use. It is the most ideal reliable product in the new century.

2. Adopting the latest technology and manufacturing processes, it first applies the latest PUM intelligent pulse width modulation technology and pulse train logic array modulation, uses high-power IGBT devices, and uses intelligent technology to improve efficiency. The frequency is as high as 40kHz, resulting in higher stability of the output high voltage and smaller ripple coefficient.

3. Using computer control technology, the output DC high voltage, current, overvoltage setting, timing, grounding, and various protection information are displayed on a large-screen LCD display.

4. *Intelligent poor grounding protection and alarm function (cannot boost voltage when grounding is poor), voltage measurement circuit disconnection protection (the instrument cannot boost voltage when the high voltage measurement circuit is disconnected), and emergency stop button greatly improve the safety of operators during operation. In special cases, the poor grounding protection alarm function can be disabled (such as when using a generator as the power supply or when the field grounding is poor but testing can still be performed). High precision and accurate measurement. The voltage and current meters are digital displays, with a voltage resolution of 0.1kV and a current resolution of 0.1uA. The voltage meter on the control box directly displays the voltage applied to the load test object, so no external voltage divider is needed, and wiring is simple. The instrument has high and low voltage terminals to measure leakage current. The high voltage terminal uses a circular shielded digital display, which is not afraid of discharge impact, has good anti-interference performance, and is suitable for field use.

Fault Inspection and Handling:

1. When the power switch is turned on, if the digital display on the control box does not light up, check the power connection and all fuses. If a fuse is damaged, replace it with a new fuse of the amperage indicated next to the fuse holder.

2. If the digital display lights up when the power switch is turned on, but the high voltage green light does not light up and high voltage cannot be applied.

(1) Fault display "Return to Zero" light is on: It has not returned to the zero position. Please turn the high voltage output adjustment knob and fine-tuning knob counterclockwise back to zero until the "Return to Zero" light goes out, then high voltage can be applied.

(2) Fault display "Other" light is on: There are two phenomena: grounding protection; disconnection protection. a. The grounding wire may not be connected properly, or the ground wire may not be reliably grounded. Please connect a reliable grounding wire, turn off the power, and restart. b. The cable connecting the control box and the high voltage tower may not be connected properly. After connecting the cable, turn off the power and restart. Or if the solder joints at both ends of the cable are desoldered, this fault will occur. Please solder the joints at both ends of the cable, turn off the power, and restart. c. A wire inside the control box may be desoldered or disconnected. Please re-solder it, turn off the power, and restart.

3. Everything is normal, but protection occurs before reaching the rated output voltage.

(1) Fault display "Overcurrent" light is on: a. The test object is short-circuited, or the leakage current is too large. b. When the load is a large capacitor, the voltage is raised too quickly. Turn off the power, restart, and slow down the voltage increase.

(2) Fault display "Overvoltage" light is on: The overvoltage protection setting knob is not set to the maximum position. Please turn it clockwise to the maximum, turn off the power, and restart.

4. When a short circuit occurs under high voltage on the test object, due to the large short-circuit current, it is possible that all fault indicator lights will light up. This is normal. Please eliminate the test object fault and then restart.

5. After the test object fault is eliminated, if the fault indicator lights are still on and high voltage cannot be applied, the power switch also serves as the fault protection reset switch. Please turn off the power and restart to boost voltage.

6. If the voltage meter digital fluctuation is too large, check whether the 7-pin aviation plug contacts at both ends of the connecting cable are desoldered or disconnected. If disconnected, please solder them.
