DC discharge rod is made of new insulating materials. It has the characteristics of being extendable and retractable. It is convenient for various high-voltage tests outdoors, especially after DC withstand voltage tests, to discharge the accumulated charge on the test object to the ground, ensuring personal safety. It is easy to carry, convenient, flexible, small in size, light in weight, and safe.
The DC discharge rod is mainly a product to ensure personal safety when testing the insulation performance of various high-voltage electrical equipment in power distribution systems and for power users. To ensure the safety of high-voltage test personnel and the operation of equipment, using a discharge rod is a very important safety measure.
In the field of high-voltage testing, safety measures are very important to ensure the safety of high-voltage test personnel and the normal operation of equipment. The DC discharge rod is a product designed to ensure personal safety when testing the insulation performance of various high-voltage electrical equipment on site in power distribution systems and for power users.
Precautions for using the DC discharge rod:
1. When discharging large-capacitance test objects, after the test is completed and the test power supply is disconnected, wait for a period of time to allow the charge on the test object to self-discharge to the ground through the voltage doubling cylinder and the test object itself. At this time, observe that the voltage on the voltmeter of the control box gradually decreases. When the voltage drops to a lower voltage, generally around 5-15kV, you can use the discharge rod to gradually move it near the test object. First, discharge through the air gap by ionization, and you can hear a hissing sound. When there is no sound, use the tip of the discharge rod to touch the test object, and finally directly ground the test object for discharge.
2. The amount of accumulated charge on a large-capacitance test object is proportional to the capacitance of the test object and the magnitude of the applied voltage and the duration of time.
3. After testing high-voltage cables of several kilometers or more, the discharge time is generally very long and requires multiple repeated discharges. The resistance capacity must be large, so a discharge rod with large capacity should be selected.
4. It is strictly forbidden to use the discharge rod to discharge the test object without disconnecting the test power supply.
5. It is strictly forbidden to step on or squeeze the discharge rod with heavy objects, and it is strictly forbidden to bend or break the discharge rod.
6. It is strictly forbidden to let the discharge rod get damp, as it affects the insulation strength. It should be stored in a dry place.
