Scb10-1000kva epoxy poured dry transformer features:
Scb10-1000kva dry type transformer manufactured by our factory is the first dry type transformer with low noise and low loss resin wound coil with product model certificate in Beijing. Due to the advanced design, high quality materials, scientific formula, strict process and high standard of testing, the product has the following characteristics:
1. The high-voltage winding is made of copper wire, while the low-voltage winding is made of copper wire or copper foil, and the glass fiber felt is filled and wrapped. In the vacuum state, it is poured with epoxy resin without packing, which forms a solid cylindrical whole after curing, with high mechanical strength, small partial discharge and high reliability.
2. Flame retardant, explosion-proof, no pollution. The insulation materials such as glass fiber of winding coil have self-extinguishing characteristics, which will not produce electric arc due to short circuit, and the resin will not produce poisonous and harmful gases under high heat.
3. The coil does not absorb moisture, and the core clip has a special anti-corrosion protection layer, which can operate in 100% relative humidity and other harsh environments. Intermittent operation without dehumidification.
4. High resistance to short circuit and lightning impact.
5. Thin resin layer inside and outside the coil, good heat dissipation performance. Natural air cooling is generally adopted. For transformers of any level of protection, the air cooling system can be configured to increase the short-term overload capacity and ensure safe operation.
6. Small size, light weight, less space, low installation cost, do not have to consider the oil drainage pool, fire protection facilities and backup power.
7. Low loss, good power saving effect, economical operation and maintenance free.
8. Because there is no danger of fire extinguishing and explosion, it can be scattered installed in the load center and fully close to the ignition point, thus reducing the line cost and saving the cost of expensive low-voltage facilities.
Scb10-1000kva epoxy poured dry transformer structure features:
1) The conductor of the high-voltage winding adopts oxygen-free copper foil with high conductivity, the insulation between turns adopts F-grade insulation material, and the inside and outside of the winding are made of imported glass grid plate as the skeleton. Copper foil with turn insulation is programmed in the high voltage foil winding machine, controlled by microcomputer, laser positioning, automatic welding with tiG arc welding of the lead line, piecewise wound, and then placed in a mold, in a vacuum, with the filler resin pouring molding.
2) The low-voltage winding is made of copper foil with the same height as the high-voltage winding, which is wound on the low-voltage foil winding machine together with F and turn insulation. During winding, the lead wire of the winding is automatically welded by a copper strip by argon arc welding and then drawn out. The middle of the winding is put into braces to form a cooling airway, and the end is sealed with resin for curing.
3) The iron core is made of cold-rolled silicon steel with high quality grain orientation, with 45 degree full inclined joints and no perforation structure of iron yoke, so as to ensure low no-load loss. The core is clamped with domestic one-step prestressed and breathable square steel clip structure, the core is fastened with insulation belt, the upper and lower clamps are drawn with inner plate structure, and the surface of the core is sealed with special resin technology, so the structural strength and clamping force are increased and the noise is also reduced.

Scb10-1000kva epoxy poured dry transformer temperature control, temperature display:
The temperature control system is composed of a temperature controller and a PTC temperature measuring element installed at the top end of the low-voltage winding, which is the most hot spot of the product, to realize the temperature control and measurement of the transformer. If the transformer winding temperature is too high due to overload operation or fault, the temperature controller will send an alarm signal, and the temperature will trip automatically when it exceeds the safe value. In the case of forced air cooling, the input or switch of the cooling environment system is determined by the temperature controller according to the winding temperature. Luohe pre-installed type substation manufacturer supply!
The wet display system directly displays the hot spot temperature of the winding in the transformer operation process, which can be used in conjunction with the temperature control system.
The temperature control and temperature display system can be installed a certain distance away from the transformer body. The length of the lead wire of the temperature measuring element is as follows:
Temperature control: < 20 m
Temperature display: < 10m(two-wire system)
< 100m(two wire with compensation wire)
Protection mode for scb10-1000 dry-type transformers of 10KV class
According to the use environment characteristics and protection requirements, the dry type transformer can choose different enclosures. IP23 protective shell is usually used to prevent the entry of solid foreign bodies with a diameter of more than 12mm and small animals such as mice, snakes, cats and birds, causing short-circuit power failure and other malignant faults, thus providing a safety barrier for live parts. If the transformer is to be installed outdoors, the IP23 protective enclosure can be selected. In addition to the above IP20 protective function, water droplets within 60° Angle from the vertical line can also be prevented. However, the IP23 housing will reduce the cooling capacity of the transformer, so pay attention to the decrease of its operating capacity when selecting it.
