Usage Method
When conducting high current tests, correctly connect the working circuit according to the circuit diagram of this product. Based on the output current size, select the appropriate position for the large and small range switches. First return the voltage regulator to zero, then press the start test button (green). At this time, hold the handle of the voltage regulator and slowly rotate the handwheel clockwise while watching the ammeter until the required current value is reached. After the test reaches the set value, immediately rotate the handwheel counterclockwise back to zero, press the stop button, and cut off the power supply.
This current booster is a dry-type high current generator produced by our company, equipped with an auto-transformer voltage regulator to output voltage (i.e., the input voltage of the generator) to obtain the required different high currents.
Precautions
1. The test work must be carried out by at least two people, one operating and one supervising to ensure safety.
2. The casing must be grounded. Do not neglect personal safety accidents due to low voltage.
3. The wires from the secondary side of the current booster to the tested object should not be too long, and the cross-sectional area should be sufficient (current density can be considered at 6-8A/mm). The contact surface should be cleaned (can be polished with fine sandpaper), otherwise the joints will heat up, and the current may not rise to the rated value.
4. Before work, check that the power supply has sufficient capacity; otherwise, the power cord will heat up and the voltage will drop, affecting normal operation.
5. There should be no flammable materials at the work site. For temperature rise tests, sufficient fire extinguishing equipment should be prepared.
6. For continuous (temperature rise) tests, someone should be on duty at the site. Regularly check the heating condition of the current booster source equipment, wires, and joints, and make records. Due to grid voltage fluctuations, pay attention to adjusting the TD to maintain the rated test current.
7. Test work should comply with the relevant provisions of the electric power safety work regulations and formulate practical safety measures.
