The role of transformer bushing terminals

The role of transformer bushing terminals has three main aspects:

1. connecting the conductive circuit

It is the conductive connection point between the transformer winding lead wire and the external transmission line. Through the terminal, the transformer internal high and low voltage windings can be connected to the external cable or bus, forming a complete transmission circuit. 2.

2. Mechanical fixing and support

terminals not only transmit current, but also play a role in fixing and supporting the external conductor, to ensure that there is a reliable mechanical connection between the conductor and the casing, to prevent the contact loosening due to vibration, wind, or the external force caused by the operation.

3. Insulation and safety

The terminals cooperate with the insulating part of the transformer casing, so as to maintain sufficient electrical insulation distance between the lead-in end of high voltage and the grounded tank and casing to avoid discharge or short circuit, and to safeguard the safety of the equipment and the person.
