SCB11 transformer can be used as a replacement product of oil-immersed distribution transformer, and is the best product in all kinds of dry-type transformers, especially suitable for urban power grids, high-rise buildings, business centers, theaters, hospitals, hotels, tunnels, subways, underground power stations, laboratories, stations, docks, airports, combined substations and other important places.

SCB11 transformer structure:

1. The coil is wound with copper wire or foil, reinforced with glass fiber, epoxy resin is poured without filler, vacuum drying, degassing and dehumidification, high mechanical strength, short circuit resistance, and strong impact resistance.

2. The head end of the high-voltage winding and the middle tap tap are embedded with copper inserts, which has good rigidity, easy to adjust gears, and is beautiful and neat.

3. The iron core is made of high-quality grain-oriented cold-rolled silicon steel sheets, and the 45-degree full-oblique multi-step joints are stacked. The surface is covered with resin insulating coating, which is moisture-resistant, rust-proof, and noise-resistant.

4. The elastic parts are clamped between the core, the clamp and the coil to make the coil in a stable compression state to reduce noise.

5. The transformer is designed according to self-cooling, and there is a longitudinal ventilation channel reserved inside the cylinder wall of the high-voltage (low-voltage) coil for overall casting, which can be equipped with a forced air cooling device (cooling fan), and the output capacity can be increased by 20% after the forced air cooling device is adopted.

6. Equipped with a thermostat, a platinum resistor (Pt100) is placed in the embedded 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 tripping functions are equipped to provide reliable overload protection devices for the dry-type transformer, so as to improve the safety of the dry-type transformer operation.

Performance characteristics:

1. Compared with SCB10 type, SCB11 transformer has lower no-load loss, no-load current and noise.

2. Safe, fireproof, pollution-free, can directly run in the load center.

3. High mechanical strength, strong short-circuit resistance, small partial discharge, good thermal stability, high reliability and long service life.

4. Good heat dissipation performance, strong overload capacity, and forced air cooling, which can increase the capacity operation.

5. Good moisture-proof performance, suitable for operation in high humidity and other harsh environments.

6. It can be equipped with a complete temperature monitoring and protection system, using an intelligent signal temperature control system, which can automatically monitor and display the respective working temperature of the phase winding on the same screen, can automatically start and stop the fan, and has alarm, trip and other function settings.

7. Small size, light weight, less floor space, low installation cost.
