The using condition of SG series transformer

1. The altitude does not exceed 1000 meters;

2. Maximum temperature + 45 ° C;

3. The highest daily average temperature + 35 ° C;

4. The highest annual average temperature + 25 ° C;

5. The minimum temperature is -30 ° C; (applicable to outdoor transformers);

6. Minimum temperature -5 ° C; (applicable to indoor transformer);

7. Relative humidity≤90%;

8. The power supply voltage waveform is similar to a sine wave;

9. Multiphase power supply voltage is approximately symmetrical;

Installation Environment of SG series transformer

1. The transformer should be installed in a ventilated and dry environment free of harmful fumes and vapors, corrosive dust, water vapor, fumes, severe humidity, and dripping water.

2. There should be a certain space around the SG series transformer for repair and maintenance.

3. The installation site should be free from severe vibration and bumps;

The wiring of SG series transformer

1. The cross-sectional wiring of the transformer input and output power lines should meet the current value requirements of their corresponding capacities;

2. The input and output three-phase power lines should be connected to the A, B and C phases of the busbar of the transformer wiring board: yellow, green, and red. Line and transformer shell (the transformer has a shell, which should correspond to the fragrance mark).

No-load inspection and operation of SG series transformer

1. Please test the insulation resistance of the transformer with a megameter before power on. The resistance of the iron core to the winding should be ≥ 2MΩ;

2. According to the random matching schematic diagram that check the input and output wiring should be accurate;

3. After the above test is completed that can be energized without load and test (or observe) whether the voltage at the input and output terminals meets the requirements;

4. After completing the above procedures and confirming the correctness which you can connect to the load to run;

5. During operation, please note that the load current should not exceed the maximum current allowed by the transformer. Please keep the transformer running under rated conditions.
