How to maintain dry-type transformers

time:2020/9/26   source:华天电力  reading:725 time

The transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. Carrying out the conversion of current and voltage, the box-type transformer cabinet thus achieves the conversion of current. Often used in communities, schools, shopping malls and other places. However, we must pay attention to the maintenance of the transformer in our daily life, which will be introduced in detail below.

Maintenance of transformer:

1. Prevent the transformer from overloading operation: If the transformer is overloaded for a long time, it will cause the coil to heat up. The insulation is gradually aging, short circuit between boxes, short circuit between phases or short circuit to ground and oil decomposition.

2. Prevent transformer core insulation from aging damage: core insulation aging or clamping bolt casing damage. Will cause the iron core to produce a large eddy current, and the iron core will heat up for a long time to cause insulation aging.

3. Prevent inadvertent damage to the insulation during maintenance: When examining and repairing the hanging core of the transformer, pay attention to protecting the coil or insulation sleeve. If scratches are found, deal with it in time.
