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 takes the lead in applying the latest PUM intelligent pulse width modulation technology and pulse train logic array modulation. It uses high-power IGBT devices and intelligent technology to improve efficiency, with a frequency up to 40kHz, resulting in higher stability of the output high voltage and smaller ripple coefficient.

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

4. *Intelligent poor grounding protection and alarm function (cannot boost voltage if grounding is poor), voltage measurement circuit disconnection protection (instrument cannot boost voltage if 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 power supply or when the site grounding is poor but testing can still be conducted). High precision and accurate measurement. Both voltage and current meters are digital displays, with voltage resolution of 0.1kV and 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 end leakage current measurement. The high voltage end uses a circular shielded digital meter 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 power switch is turned on, the digital display lights up, but the high voltage indicator 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 zero. Turn the high voltage output adjustment knob and fine adjustment knob counterclockwise back to zero until the "Return to Zero" light goes off, 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 may not be reliably grounded. 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. Connect the cable properly, turn off the power, and restart. Or if the solder joints at both ends of the cable are desoldered, this fault may occur. 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. Solder it back, 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 large capacitance, the voltage is raised too quickly. Turn off the power, restart, and slow down the voltage raising speed.

(2) Fault display "Overvoltage" light is on: The overvoltage protection setting knob is not set to the maximum. 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 are lit. This is normal. After eliminating the test object fault, 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. 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 connections at both ends of the connecting cable are desoldered or disconnected. If disconnected, solder them.
