750 kva dry type transformer

Epoxy resin is a flame-retardant, flame-retardant, self-extinguishing solid insulating material. Safe and clean epoxy resin dry-type transformers use epoxy resin as the insulating material. The high and low voltage windings are wound with copper tape (foil), and epoxy resin is poured and solidified in a vacuum to form a high-strength fiberglass structure. In addition, the high-voltage coil is completely enclosed and has strong resistance to dirt and moisture in the external environment. Epoxy resin dry-type transformers have the characteristics of good electrical performance, strong lightning impact resistance, strong short-circuit resistance, small size and light weight. A temperature display controller can be installed to display and control the operating temperature of the transformer winding to ensure the normal service life of the transformer. Most of the windings of epoxy resin cast dry-type transformers are molded by epoxy resin casting. The inherent performance of the windings after molding is also determined. Once the performance of the molded windings does not meet the specified standards, they have to be scrapped. Therefore, in order to ensure the casting quality of the windings, the structure of the pre-cast windings must be reliable. The product has smaller partial discharge, low noise and strong heat dissipation ability. It can operate at 140% rated load for a long time under forced air cooling conditions and is equipped with an intelligent temperature controller with fault alarm, over-temperature alarm and over-temperature trip. and other functions.
