Application range

SC(ZB)9(JUC) series dry transformer is introduced from swiss belonging to the resin pouring film insulation dry power transformer with the international advanced level. It’s widely used by the high environmental demand places, including the high building, commercial center, airport, station, pier, subway, factory and underground distribution, marine petroleum well drilling platform and power plant etc.

Feature

High voltage winding adopts the lacquer wrapped copper wire and the low voltage is wound with the copper foil. The high voltage winding adopts the fiberglas gridding cloth board, under the vacuum state, poured with the import epoxy resin, after solidifying, form the solid whole, with high mechanical strength, small partial discharge and high reliability. Flame retardant, explsion proof, do not pollute environment, environmental protection type, that can be installed in load center.
Coil does not inhale the moist. Core and clip can run under 100% relative humidity and other ban environment through the special technological treatment. Disconnected running needs not do moisture treatment.
Short circuit resistant, high lightning impact level and big overload ability.
Thin coil internal and external resin insulation layer and good hot scattered performance. Cool way normally adopts the air nature cooling(AN). Any protective grade transformer can deploy the air-cooling system (AF).
Low wastage, good energy saving effect, economic running economy maintenance-free.
Small volume, light weight, small landing space and convenient installation.
Temperature control system consists of the temperature controller and PTC temperature testing element mounted on the product hottest point also the low voltage winding upper end, realizes the temperature measurement and control to the transformer. If causing the too high temperature because of overload operation or fault, the temperature controller will send the alarm signal, when the temerature exceeds the safe value, it will trip automatically. When adopting the force air-cooling, the temperature controller will decide the cool fan jump in or switchover according to the low or high temperature degree of the winding.
Temperature indicating system directly indicates the winding hot point temperature in the running course of the transformer, which can be combined with the temperature control system.

Speafications

Note: The load-ratio voltage series transformer only do regulation to the following three data:
1. Weight increases 250Kg;
2. LOad-ratio switch distributes at the side of the transformer a increase 650mm or right face b increase 750mm;
3. Capacity 800KVA height e is 1600mm.
