The DC high-voltage generatorunder the UHV power company can help many power workers conduct various power tests more conveniently.

1、 Precautions for using discharge rods as supporting products for DC high-voltage generators

When discharging a large capacitor sample, after the test is completed, disconnect the test power and wait for a period of time to allow the charge on the sample to self discharge to the ground through the voltage doubler and grounding terminal. The sample itself. It can be observed that the voltage reading on the voltmeter on the control box is gradually decreasing. When the voltmeter drops to a lower voltage, usually around 5Kv~15Kv, a discharge rod can be gradually moved to the vicinity of the tested product and discharged freely through air. At this time, a hissing sound can be heard. If there is no sound, the tip of the discharge rod can be used to contact the sample, and finally the sample can be directly discharged to the ground.

2. The accumulated charge of a large capacitance sample is directly proportional to the size of the sample capacitance, the level of applied voltage, and the duration of time.

3. High voltage cables undergo tests over several kilometers, and the discharge time is generally long, requiring repeated discharge. The resistance capacity is large, and a large capacity discharge rod needs to be ordered.

4. It is strictly prohibited to discharge the test sample with a DC high-voltage discharge rod without unplugging the test power supply.

5. It is strictly prohibited to squeeze or bend DC high-voltage discharge rods with feet or heavy objects.

6. It is strictly prohibited to damp the DC high-voltage discharge rod, which may affect the insulation strength. It should be placed in a dry place.

2、 Correct use of supporting products and discharge rods for DC high-voltage generators

1. Pull out all the telescopic parts of the portable telescopic new DC high-voltage discharge rod.

2. Insert the prepared ground wire plug into the socket at the end of the DC high-voltage discharge rod, and ground the other end of the ground wire. The grounding should be reliable.

3. After the test is completed, the boost knob of the DC high voltage generator control box returns to the zero position. At this time, it can be observed that the voltage on the voltmeter on the control box drops to around 15KV~20KV before discharge

4. When discharging, first use the metal tip at the front end of the DC high-voltage discharge rod to slowly lean against the tested product that has been disconnected from the test power supply. At this point, the electrical energy released by the discharge rod is discharged to the ground through the discharge resistor. Then hook the sample with the hook on the discharge pole for secondary electrical protection.

3、 Application scope of discharge rod for DC high-voltage generator supporting products

The portable telescopic DC high-voltage discharge rod is made of a new type of insulation material and has the characteristics of stretchability and contractibility. The portable telescopic new type of DC high-voltage discharge rod is suitable for outdoor high-voltage testing. Especially after DC voltage testing, the accumulated charge on the sample is released to the ground to ensure personal safety. A discharge rod should be used during discharge. It is an essential equipment to ensure the personal safety of every tester. Portable telescopic DC high-voltage discharge rod, convenient and flexible, small in size, light in weight, safe and reliable, is an indispensable safety tool for high-voltage operators.
