The Function of Porcelain Bushing

The Function of Porcelain Bushing

The effect of the transformer porcelain bushing is to high, low voltage lead arch to the outside of the tank, not only as a lead-to-place insulation, but also bear the role of the fixed lead, the transformer bushing is one of the transformer carrier components, and in the transformer operation, Long-term through the load current, when a short circuit is short-circuited outside the transformer occurs outside. Therefore, the transformer bushing has the following requirements:

1) It must have a predetermined electrical strength and sufficient mechanical strength.

2) It must have good thermal stability and can withstand the moment of time when short-circuiting.

3) Small shape, small quality, good sealing performance, strong versatility and easy maintenance.
