SCB13 three-phase dry-type power transformer
The SCB13 three-phase dry-type power transformer is safe, flame-retardant and fire-proof, and has no pollution. It can be directly installed in the load center. Maintenance free and easy to install. It has good moisture-proof performance and can be put into operation without pre-drying after shutdown. Low loss, low partial discharge, low noise, and 120% rated load operation under forced air cooling. We have a complete temperature protection control system to provide reliable protection for the safe operation of the transformer. The reliability index of this product has reached the international advanced level.
1. The coil is wound by copper wire or foil, reinforced with glass fiber, epoxy resin without filler vacuum drying, degassing and dehumidification, casting, high mechanical strength, short circuit resistance and strong impact resistance.
2. The first end of the high-voltage winding and the intermediate tapping tap are embedded with copper inserts. The steel is good, easy to shift, beautiful and neat.
3, the iron core is made of high-quality grain oriented cold-rolled silicon steel sheet, 45 degree full oblique multi-step seam. The surface is covered with a resin insulating coating to resist moisture, rust and noise.
4. The elastic core is clamped between the iron core, the clamp and the coil, so that the coil is in a stable compression state to reduce noise.
5. The three-phase transformer is designed according to self-cooling. The high-low (low) pressure coil wall of the whole casting is reserved with a longitudinal air passage inside, which can be equipped with a forced air cooling device (cooling fan). After the forced air cooling device is used, the output can be improved. The capacity is 20%.
6. With a thermostat, place a platinum resistor (Pt100) in the pre-buried hole at the top of the low voltage coil. In order to monitor the temperature rise of the transformer winding, the cooling fan is automatically started and stopped, and the fault alarm, over-temperature alarm and over-temperature trip function are provided to provide a reliable overload protection device for the dry-type transformer, thereby improving the safety of the dry-type transformer operation.
product structure
Iron core: The iron core is made of imported high-quality cold-rolled silicon steel sheet, the third-order full-slant joint structure, the core column is bundled with F-class non-latitude belt, and the iron core surface is sealed with epoxy resin, which reduces the no-load loss and no-load current. And the iron sheet noise, the clip and the back part are specially treated to improve the appearance quality of the product.
Protective casing and outlet busbar: The protective casing provides further protection for the transformer. The protection grades are IP20, IP23 and so on. The outer casing material is aluminum alloy, cold rolled steel plate, stainless steel, etc. for users to choose. The standard busbar discharge line for low-voltage outlets can be used for both side outlets and top outlets. Special outlets can also be designed for users.
