Three-phase high current generator usage and precautions
Three-phase high current generator use method:
When doing a large current test, connect the working circuit correctly according to the circuit diagram of this product. According to the size of the output current, select the position of the large and small range switches. Turn the regulator back to zero and press the start test button (green). At this time, slowly hold the regulator handle clockwise to rotate the regulator handwheel and watch the ammeter until the desired current value is reached. After the test reaches a predetermined value, the counterclockwise direction of the regulator hand wheel is immediately returned to zero, and the stop button is pressed to cut off the power supply.
Three-phase high current generator Note:
1. The test work shall not be less than two people. One person shall operate and one person shall supervise operations to ensure safety.
2. The housing must be grounded. Do not neglect safety precautions to prevent personal injury due to low voltage.
3. The flow path of the riser secondary to the test object should not be too long and the cross-sectional area should be sufficient (current density can be considered as 6-8A/mm). The contact surface should be clean (gauze can be used to light), otherwise the joint will heat up, even The current rises less than the rated value.
4. Before working, check that the power supply has sufficient capacity, or the power cord heats up and the voltage drops to affect normal operation.
5. The work site should not have flammable materials. Temperature rise test should prepare enough fire extinguishing equipment.
6. Continuity (heating) test, on-site personnel should be on duty. And regularly check the source of rising equipment, wires, joints, fever, make a good record. Due to changes in grid voltage, attention is paid to adjusting TD in order to maintain the rated test current.
7. The test work shall comply with the relevant provisions of the electrical safety work regulations and formulate practical safety measures.
