I. Overview
The discharge rod and the DC discharge rod are made of new insulating materials. It has the characteristics of elongation and shrinkage. The portable telescopic new discharge rod is easy to use in various outdoor high voltage tests, especially after the DC withstand voltage test. The electric charge accumulated on the test product is discharged to the ground to ensure personal safety. Using the discharge rod to discharge is a necessary weapon to ensure the personal safety of each tester. The portable telescopic discharge rod is easy to carry, convenient and flexible. With small size, light weight, safety and reliability, it is an indispensable safety tool for high-voltage workers.
II. Main technical parameters
1. Shrink size of discharge rod: length 350mm,
Outer diameter?35mm
2. Number of shrinking sections of discharge rod: 5 sections.
3. Discharge rod extension size: extension length 1100mm
4. Discharge voltage range: 5Kv～70Kv
III. Matters needing attention
1. When discharging the large-capacitance test product, after the test is completed, after disconnecting the test power supply, it should wait for a period of time to make the charge on the test product pass through the voltage multiplier and the test product itself to self-discharge to the ground. At this time, it can be Observe that the voltage of the voltmeter on the control box is gradually decreasing. When the voltmeter drops to a lower voltage, generally around 5Kv ~ 15Kv, the discharge rod can be used to gradually move to the vicinity of the test sample. At this time, a hissing sound can be heard. When there is no sound, touch the test object with the tip of the discharge rod, and finally discharge the test object directly to the ground.
2. The size of the accumulated charge of the large capacitance test product is proportional to the size of the capacitance of the test product and the level of the applied voltage and the length of time.
3. After the test of high-voltage cables with more than a few kilometers, the discharge time is generally very long, and repeated discharges are required. The resistance capacity needs to be large, and a large-capacity discharge rod needs to be ordered.
4. It is strictly forbidden to discharge the test product with a discharge rod without pulling the test power supply.
5. It is strictly forbidden to squeeze the discharge rod with feet and heavy objects, and it is strictly forbidden to bend or break the discharge rod.
6. It is strictly forbidden to damp the discharge rod, which will affect the insulation strength, and should be placed in a dry place.
