Usage Method and Main Parameters of High Current Generator



High Current Generator is specially designed and manufactured for current load tests and temperature rise tests of electrical equipment such as various switches, current transformers and other electrical appliances in power departments and industrial and mining enterprises.

　　 This series of products adopts integrated or split structure depending on product volume and weight. It features stepless adjustment of output current, uses 0.1-class standard current transformers, digital display, balanced current rise, wide load variation range, reliable operation, simple operation, and safety. It is an ideal equipment for current rise or temperature rise tests in industrial and mining enterprises.

　　 1. Main Technical Parameters:

　　 1. Power supply voltage: 220V 50HZ

　　 2. Voltage regulator capacity: 10KVA

　　 3. Main unit capacity: 12KVA

　　 4. Input current: 40A

　　 5. Output current: 2500A

　　 6. Output voltage: 7V

　　 2. Usage Method 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 meters to each other, turn on the air switch, and the current generator waits 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 any abnormal phenomenon is found, 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, turn off the air switch to cut off the power supply, cut off the working power, and then remove the test wiring to ensure safety.

　　 3. Operating Environment:

　　 1. Ambient temperature: -10℃ to 40℃

　　 2. The product should be placed in a place without gas vapor that seriously affects transformer insulation, chemical deposition dust, dirt, and other explosive media.

　　 3. Working power supply: 220V/380V ±10% 50HZ

　　 4. Precautions:

　　 1. For newly installed or long-term unused current generators, before operation, measure the insulation resistance between coils and between coils and ground with a 1500 megohm meter. Only when the resistance value is not lower than 0.5 megohm can it be used.

　　 2. During use, the current generator transformer and the operation console must be reliably grounded to ensure safety.

　　 3. When using, the current should be raised slowly and evenly, and excessive vibration should be avoided during handling.

　　 4. The contact surface between the voltage regulator and the carbon brush should be kept clean. If necessary, wipe it clean with cotton yarn dipped in 90% alcohol.

　　 5. This equipment is designed for short-time work, so it is not allowed to work under rated capacity for a long time, especially not allowed to operate exceeding the rated current to prevent overheating.

　　 6. This equipment should be stored in a clean, ventilated, and dry indoor place.
