Dry-type transformer wiring should need to pay attention to the wiring method and a variety of transformer wiring accuracy, complete the dry-type transformer fast and accurate to carry out, which is also a dry-type transformer in the development of wiring for the basis of the needs, if you can do a bad dry-type transformer performance not only will not be revealed, there are also a lot of common failures. About dry-type transformer wiring methods and processes you can look at the process.

1, wiring dry-type transformer “input” and “output” wiring terminals with megohmmeter to detect it with the grounding resistance of the ground wire.

2, dry-type transformer input, output power plug cross-section wiring should meet their own current size of small provisions; according to the 2-2.5A/min2 current strength equipped with appropriate.

3, input, output three-phase power line should be in accordance with the dry-type transformer terminal board busbar slot color yellow, green, red, each connected to phase A, B, C, neutral zero line should be connected to the neutral zero line with the dry-type transformer voltage transformer, wire connectors and dry-type transformer chassis (such as the dry-type transformer has a main chassis should be interconnected with the shell ground marking matches). Check the input and output lines, to determine the proper and accurate.

4, the first full load plug, observation and inspection of input and output voltage in accordance with the regulations. At the same time to observe and check the internal structure of the equipment whether there are abnormal sounds, ignition, odor and other abnormal conditions, if abnormal, please immediately disconnect the input switching power.

5, when the full load detection and normal, you can connect the load.

Above is a small editor for you to bring the dry-type transformer wiring methods and steps, if also interested in other content, you can also consult the editor, the editor will continue to update for you.
