Instructions for Five-Level Testing Equipment DC High Voltage Generator 60KV/2mA
1. Instructions for Panel Components
(1) High-frequency output and voltage/current measurement cable quick-connect multi-pin
Socket: Used to connect the main unit and the voltage doubling section. When connecting, align the white dot on the cable plug with the white dot on the socket and turn clockwise until it locks. To disconnect, turn the cable plug counterclockwise.
Note: When installing or removing the plug, hold the metal ring of the plug and rotate. Do not rotate or pull the cable by the wire, as this may cause breakage between the plug and the cable.
(2) Digital Voltmeter: LCD digital display of DC high voltage output, unit in kV, minimum resolution of ±0.1kV.
(3) Digital Ammeter: LCD digital display of DC high voltage output current, unit in uA, minimum resolution of ±0.1uA.
(4) Power Fuse Holder: Fuse is 5A.
(5) Power Input Socket: Single-phase AC 220V±10%, 50Hz. Connect the provided power cord to the power input socket (the socket has a built-in fuse of 5A or a separate fuse holder).
(6) Grounding Terminal: This grounding terminal should be connected to the grounding terminal of the voltage doubling cylinder and the test object's ground at one point, then connected to the grounding grid.
(7) Overvoltage Setting Rotary Switch: Used to set the overvoltage protection value. The overvoltage setting range is 0.05-1.2 times the rated voltage, and the value displayed on the rotary switch is in kV.
(7) 75% VDC-1mA Yellow Illuminated Button: Active when the red light is on. When the yellow button is pressed, the yellow light turns on, and the output high voltage drops to 0.75 times the original value and holds this state. This function is specifically for quick measurement of zinc oxide arresters using 0.75VDC-1mA. Pressing the green button turns off both the red and yellow lights, cutting off the high voltage and exiting the 0.75 times state.
(10) Green Illuminated Button: When the green light is on, it indicates that the power is connected and the high voltage is off. In the red light state, pressing the green button turns off the red light and turns on the green light, cutting off the high voltage circuit.
(11) Red Illuminated Button, High Voltage On Button, High Voltage Indicator: In the green light state, pressing the red button turns on the red light and turns off the green light, indicating that the high voltage circuit is connected. At this point, voltage can be increased. This button is only effective when the voltage adjustment potentiometer is at zero. If the red button is pressed and the red light turns on, but the green light remains on, and when the button is released the red light turns off and the green light turns on, it indicates that the internal protection circuit has activated.
In this case, you must turn off the power and check whether the overvoltage setting rotary switch is set to less than 5% of the full scale and whether there are any other faults. After confirming no issues, turn the power back on.
