On May 30, 2023, 5 SCB10-2500KVA-13.8/0.4KV all-copper-drying transformers were successfully delivered in the Philippines. It took 45 days. Hengfeng Friends strictly controlled the quality of production.
Why is the maximum selection of 0.4kV dry transformers only 2500kva?
First of all, the maximum transformer with a low voltage of 0.4kV is more than 2500kva, 3150kva or even 4000kva can be done. The reason for the selection is limited to 2500kva, mainly the following reasons:
1. The transmission distance of low voltage 0.4kV is very short, and the line long line loss and voltage of the line will be very large, which is not good for electricity safety and energy saving.
2. The rated current of 2500kva low voltage 0.4kV is 3608A. Now the rated current of the low pressure cabinet is 4000A. Consider overloading. If a larger transformer is used, it is difficult to find the appropriate low -voltage switch cabinet and circuit breaker.
3. There are few large 400V loads in the actual situation, so the response needs are relatively small.
> Hengfengyou epoxy resin dry transformer product advantage:
·Customization
6-35kV epoxy resin dry test transformer has small size, compact structure, low temperature resistance and no cracking, and is especially suitable for cold northern Russia.
· Leading technology
High -pressure copper belt winding technology, flame retardant formula vacuum pouring, safety, fire prevention, non -pollution, can run directly in the center of load; low -pressure copper foil winding technology, thermosetable epoxy prefabricated insulation, strong load capacity, forced wind and cold It can increase the capacity operation; the high -quality iron core 45 ° full oblique seam step -by -step stacking structure, low loss, low noise, obvious energy saving effect, dry transformers can be equipped with a perfect temperature detection and protection system. The intelligent signal temperature control system can be used to automatically detect and tour the respective work temperature of the three -phase winding. It can automatically start and stop the fan, and have functions such as alarm and check -out to avoid maintenance.
·Iron core
The material of the iron core uses the high -quality cold -rolled granules of the insulation of mineral oxides to the silicon steel sheet; through the control of the cutting and overlap process of silicon steel sheets, the level of loss and air load current and noise are minimized, and the mechanical strength is high. The short -circuit ability is strong, the local discharge is small, the thermal stability is good, the reliability is high, and the service life is long.
· Low -voltage winding
The low -pressure winding is made of high -quality copper foil winding
Bate uses heat -solid epoxy pre -immersed insulation
The winding of the end of the winding end is pre -immersed in insulation
Have excellent insulation tolerance
It has a very good tolerance for the radial stress caused by short circuit
Low -voltage winding line terminals are tin -plated copper row
Place the entire winding in the oven to 140 ° C. After 4 hours of aggregation, it has excellent corrosion ability of anti -industrial gases
· High -pressure winding
The technical technology of the insulation copper line is winding and applied to the exclusive patent of Hengfeng You Electric
For small -capacity products, the high -voltage winding uses the linear voltage gradient from the top to the bottom
For large capacity products, the high -pressure winding uses the "band wind" technology winding system
The application of these methods makes the electric field between adjacent conductors very low
During normal operation and transportation, the transformer is reliable structure
·High-quality materials
Baosteel, Wugang Silicon Steel
China produces high -quality oxygen copper
Swiss Hunsmai Ring Oxygen resin (including flame retardant fillers)
·Patented technology
The high -voltage coil is poured in high vacuum, and the pouring material system adds a unique flame retardant filler, which is the technology of Hengfeng Friends Electric Patent. When the transformer is exposed to the flame, the transformer will go out immediately. With unique and excellent flame retardant characteristics and ability to adapt to the harsh working environment.
·Conditions of Use
1. The altitude is less than 1000m, the air temperature is -25 ° C ~ 40 ° C, and the humidity is less than 90%(+25 ° C)
2. The vertical tilt does not exceed 5 °, there is no strenuous vibration place, and the outdoor wind speed does not exceed 35m/s
3. Gas, electric conductivity without serious affecting transformer insulation; places without explosion risk, non -corrosive electrical components
4. Beyond the above normal use environmental conditions, customers can customize separately with Hengfengyou Electric.
