The special three-phase high current generator for temperature rise is specially designed and manufactured for power departments and industrial and mining enterprises in electrical equipment tests such as: high current generators for various busways, switches, current transformers, and other electrical equipment for current load tests and temperature rise tests.
This series of products adopts integrated or split structure depending on product volume and weight. The thermal relay calibration instrument has stepless adjustment of output current, uses 0.1 level standard transformer, digital display, balanced current rise, large load variation range, reliable operation, simple operation, and safety. The thermal relay tester is an ideal equipment for current rise or temperature rise tests in industrial and mining enterprises.
Main technical parameters:
1. Power supply voltage: 380V 50HZ
2. Voltage regulator capacity: 100KVA
3. Main unit capacity: 120KVA
4. Input current: 400A
5. Output current: 10000A
Operating environment:
1. Ambient temperature: -10℃ to 40℃
2. The product should be free from gases, vapors, chemical deposits, dust, dirt, and other places that seriously affect transformer insulation.
3. Working power supply: 220V/380V ±10% 50HZ
Usage methods and precautions:
1. The instrument must be properly grounded.
2. Connect the power supply, connect the output terminal of the control console to the input terminal of the generator, connect the instruments to the instruments, turn on the air switch, and the current generator is now waiting for current rise.
3. Rotate the voltage regulator evenly clockwise, pay attention to the output current indication on the control console, until the required high current is reached.
4. During the test, once abnormal conditions are found, the relay protection calibration instrument should immediately cut off the air switch power supply, find out the cause, and then conduct the test again.
5. After the test, the voltage regulator must be returned to zero, press the air switch to cut off the power supply, cut off the working power supply, and remove the test wiring in the reverse direction to ensure safety. HNDL10000 High Current Temperature Rise Test Equipment
