Product description
SCB14 dry-type transformer is widely used in lighting, multi-storey buildings, airports, port CNC machinery and equipment manufacturing and other places, when the natural air is cold, SCB14 dry-type transformer can operate continuously for a long time under short-circuit capacity. When forced to be air-cooled, the output volume of the SCB14 dry-type transformer can be increased by 50%. It can be used for intermittent overload operation, or emergency safety accident overload operation; SCB14 dry-type transformer has safety, fire safety, and can directly operate the load center. SCB14 dry-type transformer adopts domestic first-class technology. High mechanical strength, small partial discharge, good thermal stability, good stability and durability. No consumption, low noise, good energy saving effect, durable. The thermal conductivity is good, the overload capacity is strong, and the volume operation needs to be increased when forcing air cooling. It has good moisture resistance and can be integrated into high temperature environments and other extreme environments.
Performance parameters
1. Rated current (KV): The rated current of SCB14 dry-type transformer is basically in the middle of 6~35KV, which is mainly suitable for power supply system.
2. Rated voltage (A): The rated voltage refers to the maximum current amount of the system under the required conditions, which can meet the needs of different consumers.
3. Maximum power (KVA): The maximum power of SCB14 dry-type transformer is basically in the middle of 30~2500KVA, which can meet the requirements of power supply systems of different loads, and is an efficient, stable and reliable substation equipment.
4. Grade: The grade of SCB14 dry-type transformer is screened according to the national power industry standards GB1094.1, GB1094.2 and GB1094.3, mainly including YyN0, DYN11, YNd11 and YNd1 and other four levels.
5. Flame retardant grade: The insulation resistance of SCB14 dry-type transformer is class F or H, which can effectively resist harsh environments such as continuous high temperature and high current, and maintain long-term efficient operation.
6. Short-circuit impedance: The short-circuit impedance of SCB14 dry-type transformer is one of the most important technical parameters, and its magnitude is related to the length of winding. Generally speaking, the higher the value, the lower the short-circuit capacity value, making it more safe and reliable.
Product Advantages and Advantages:
1) Green environmental protection
SCB14 dry-type transformer meets the 2020 version of the national standard for level 3 energy efficiency: SCB14 meets the 2020 version of the national standard level 2 energy efficiency: SCB18 meets the 2020 version of the level 1 energy efficiency.
2) 45 degree full oblique seven-step piece seam core
The core is made of high-quality and high-magnetic grain oriented cold-rolled ferrite core, 45-degree full-oblique seven-step piece joint, special tablet sheet metal bending and rack structure is adopted, and the core column is bundled with insulating tape; The interior is coated with unique epoxy resin to treat it with waterproof and rust resistance, which effectively reduces no-load loss, no-load current and iron mob noise.
3) Double-layer barrel type high-voltage ignition line by section
The high-voltage winding electrical conductor is made of F-class or H-grade insulated copper wire coil inductor, which is made of long-cut glass fiber felt as the improved filler, and is poured with epoxy resin glue asphalt mixture in a vacuum state (1-3mbar). Effectively suppress the partial discharge situation, and the partial discharge amount shall not exceed 5PC.
4) Vertical tubing foil structure low-voltage solenoid coil
The low-voltage electromagnetic coil is made of high-quality foil conductor and coil inductor in the automatic foil winding machine; The prepreg DMD is used as the interlayer insulation, the external environment is made of prepreg glass fiber cloth as the insulation layer, the upper and lower parts are blocked with epoxy resin glue, and then the curing furnace is generally dry and solid, and the moisture-proof performance is good.
5) Firm and beautiful maintenance of the chassis
IP20 can prevent liquids with a diameter of more than 12mm from entering and can resist accidental collisions: in addition to the function of IP20, IP23 can also avoid the injection of water droplets within 60 angles to the straight line, which is suitable for outdoor installation and application; Support customization.
6) Complete over-temperature protection control system
The overheat protection device is mainly used to complete the detection and control of the ambient temperature of the transformer through the PT thermistor electrocathode in the low-voltage line entertainment industry through the embedded parts. The inspection of the transformer during operation shows the value of the three-phase winding: the value of the hottest-phase winding; reported a power outage; Light control warning, centrifugal fan operation: centrifugal fan overpressure protection and computer interface.
