SLQ AC/DC High Current Generator User Manual

 

 
I. Overview:

  The SLQ series high current generatoris specially designed and manufactured for electrical equipment tests in power departments and industrial/mining enterprises, such as current load tests and temperature rise tests for various switches, current transformers, and other electrical equipment.

    This series of products adopts split/integrated structure depending on product volume and weight, featuring stepless current adjustment, 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.

II. Main Technical Parameters:



III. Operating Environment:

1. Working Power Supply: 220V/380V ±10% 50HZ

2. Ambient Temperature: —10℃—40℃

3. The product should be placed in an environment free from gases, vapors, chemical dust, dirt, or other media that seriously affect transformer insulation.

IV. Working Principle:

    After connecting the working power supply, this series of products adjusts the output voltage of the voltage regulator to obtain the required high current for testing. The working principle diagram is as follows:

 V. Usage Methods and Precautions:

    1. Connect the working circuit according to the electrical schematic diagram. The transformer casing and operating console must be properly grounded.

    2. Connect the power supply, and the green indicator light on the operating console will turn on. Press the start button, and the red indicator light will turn on, at which point the current generator is ready for current rise.

    3. Rotate the voltage regulator evenly clockwise, paying attention to the output current indication on the operating console until the required high current is reached. To ensure testing accuracy, a standard ammeter can be connected in series at the instrument terminals.

    4. During the test, if any abnormal phenomenon is found, immediately cut off the power supply, investigate the cause, and then proceed with the test.

    5. After the test, the voltage regulator must be returned to zero, press the stop button to cut off the power supply, and then disconnect the working power supply before removing the test wiring to ensure safety.

VI. Precautions:

    1. This equipment is designed for short-term operation, so it is not allowed to operate at rated capacity for extended periods, especially not exceeding the rated current, to prevent overheating. The time limits are as follows: 

2. For newly installed transformers or those not used for a long time, measure the insulation resistance between coils and between coils and ground with a 1500 megohmmeter before operation. Only when the resistance value is not less than 0.5 megohms can it be used.

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

4. When in use, the current should be increased slowly and evenly, and avoid excessive vibration during handling.

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

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