Description
The XHHV515-8L High voltage pulse generator is a tie-rod portable integrated device, which is mainly used for shock discharge during low-voltage cable fault testing. The pulse generator adopts humanized design operation mode, high-precision dedicated high-voltage electronic components and high-frequency high-voltage technology, which is easy to operate, light in weight and easy to carry.
Panel introductionPanel function description
1. Safety ground: The ground of the instrument shell must be reliably connected to the
ground in order to prevent the instrument shell from being electrified or electric shock to
personnel.
2. High-voltage ground: Also known as high-voltage tail, it must be grounded reliably to
prevent high-voltage leakage and discharge. Poor contact may cause failure to boost
the voltage, high voltage breakdown of the internal components of the instrument, and
safety accidents caused by leakage or discharge inside the instrument.
3. Sampling ground: The negative terminal of the pulse energy storage capacitor has a
high voltage and must be grounded reliably. It is used for sampling when the waveform
is sampled under the high-voltage flashover state of the cable fault tester. (WithoutHigh voltage surge generator
high-voltage flashover sampling, reliable grounding is still required).
4. Discharge button: Press this button to make contact with the ball gap, and discharge
manually. (The duration of each key press cannot exceed 1s).
5. High voltage start button: When the start button light is on, it means that the voltage
output is in the zero position. When the light is on, the start button is valid. If the start
button light is not on after turning on the power switch, turn the voltage adjustment knob
counterclockwise until the light is on. When the button light is on, press this button to
start the device and generate high voltage output.
6. High-voltage stop button: When the test is completed or an abnormality occurs,
press this button to cut off the high-voltage output, the high-voltage light goes out, and
the internal discharge ball stops working. When the stop key is on, it means there is
high voltage output, and when it is off, it means there is no high voltage output.
7. Over-current protection switch: When pressed, it means that the over-current
protection function has started; when it is popped up, it means that the instrument has
triggered the over-current protection.
8. Voltage adjustment: After turning on the device, you must first turn the knob
counterclockwise to the end, press the start button, and then adjust clockwise to
increase the output high voltage from small to large, and adjust counterclockwise to
reduce the output high voltage from large to small.
9. Power switch: "I gear" turns on the AC 220V power supply switch, and "0 gear" turns
off the system power.
10. The fuse holder: the place where the fuse of the AC 220V power supply system is
installed.
11. Power socket: the working power supply of the instrument, AC 220V connection
port.
12. Time setting: Set the discharge time interval.
13. Ammeter: indication of the current on the high voltage side.
14. Voltmeter: high voltage output voltage indicating kV meter.
15. High-voltage output (EMP): When impacting discharge, connect the high-voltage
output line.
16. High voltage output (DC): When DC withstand voltage, connect the high voltage
output line
