Common Fault Handling of DC High Voltage Generator - Yangzhou DARUI



Recommended by DARUI Electric



 DC high voltage generator provides a DC high voltage source, specifically used to test the electrical insulation strength and leakage current of power devices. 



Precautions during testing:



1. To ensure personal safety, users are repeatedly reminded to ensure good grounding of the control box and the voltage doubling cylinder, as well as the discharge of the test object and the voltage doubling cylinder after shutdown.



2. Prevent foreign objects from entering the control box. If the control box has a fan, check regularly whether the fan is operating normally.



3. When the insulating cylinder of the voltage doubling cylinder is dirty, wipe it clean with a dry cloth. Do not use organic solvents such as alcohol or gasoline. Detergent can be used to clean the surface of the insulating cylinder, and it can only be used after air drying. When transporting or not in use, place it in the box.



4. When replacing the fuse, replace it according to the amperage marked next to the fuse holder.



5. If the high-voltage shielded microammeter displays "LOW BAT", replace the 9V battery to avoid measurement errors.



6. Without permission, do not open the control box and the voltage doubling cylinder, otherwise it will affect the product warranty. The manufacturer is not responsible for self-disassembly.



7. During transportation, the instrument should avoid rain erosion, and prevent collision and falling.



Common fault inspection and handling:



1. After turning on the power switch, the green light does not light up. Fault causes: 1) The power cord is open; 2) The power fuse is blown. Replace the power cord; Handling method: Replace the fuse.



2. Press the red button but the red light does not light up. Fault cause: The voltage regulator potentiometer is not returned to zero; Handling method: Return the potentiometer to zero.



3. Press the red button, the red light lights up, but when boosting, the red light goes off and the green light lights up; Fault cause: The high-voltage output end is grounded or the test object is short-circuited; Handling method: Check the output cable and check the test object.



4. During boosting, the red light goes off and the green light lights up; Fault cause: The test object discharges or breaks down, overvoltage or overcurrent protection acts; Handling method: Check the test object and reset the setting value.
