Correct installation method of transformer

The correct installation method of transformer is as follows:

Materials/Tools: mutual inductor, conductor, bronze medal, spirit level, wrench.

1. wiring: install the power wiring on the transformer and connect it to the power bus of the main transformer. The rated current shall be greater than or equal to the rated current of the transformer.

2. Installation: Adjust the whole transformer horizontally to make it horizontal or vertical.

3. Calibration: loosen the taps on both sides of the transformer and calibrate with a specific voltage and current adjustment method to ensure that the measured value of the output voltage and current of the transformer is consistent with the power frequency.

4. Check: compare the output current and voltage of the transformer with the actual voltage and current. If it meets the requirements, the installation is over.

Matters needing attention in installing transformer

Before installation, the open-ended current transformer must be connected with an ammeter (or other measuring device) for the second time to ensure that the transformer will not open for the second time; Put all open-ended current transformers with secondary wires on site and wait for installation; If the on-site primary bus is a cable, it can be installed live; If the primary bus is bronze, live working requires high proficiency of operators.

Before installation, insulation protection measures shall be taken; When installing the transformer, foreign matters such as impurities and dust shall not fall into the core section, so as not to affect the performance of the transformer. Open-ended transformer can run with electricity, but for the safety of operators, it is best to run without electricity as much as possible.
