Description
What is epoxy resin transformer?
A dry type transformer is a transformer that does not use liquid as insulation for its winding or core. Instead the windings and core are kept within a sealed cast epoxy resin. Cast resin dry type transformers are used in high moisture areas.
Why resin is used in transformer?
Better insulation: The resin is a very effective electrical insulator, which helps prevent short circuits and system malfunctions. Easy maintenance: Since the resin transformer does not require insulating oil, maintenance is much easier to carry out and less expensive.
Features and Devices of Epoxy Resin Transformers
Epoxy resin transformers can be used as replacement products for oil-immersed distribution transformers. They are products with better performance among all kinds of dry type transformers. They are 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.
??. Features of epoxy resin transformers
Due to advanced design, high-quality materials, scientific formula, strict process and high-standard testing, the product has the following characteristics:
1. The high-voltage coil is made of copper wire, and the low-voltage coil is wound with copper wire or copper foil. Epoxy resin is poured in a vacuum state. After curing, it forms a solid cylindrical whole with high mechanical strength, small partial discharge, and high reliability.
2. Flame retardant, explosion-proof, non-polluting environment. The glass fiber and other insulating materials used for winding coils of epoxy resin transformers have self-extinguishing characteristics, and will not generate arcs due to short circuits, and the resin will not produce toxic and harmful gases under high heat.
3. The coil does not absorb moisture, and the iron core clip has a special anti-corrosion protective layer, which can be used in 100% relative humidity and other harsh environments. Intermittent operation without dehumidification treatment.
4. High level of anti-short circuit and lightning impact.
5. The inner and outer resin layers of the coil are thin, and the heat dissipation performance is good. The cooling method generally adopts air natural cooling (AN). For power transformers with any protection level, air cooling system (AF) can be configured to improve short-term overload capacity and ensure safe operation.
6. Low loss, good power saving effect, economical operation and maintenance-free.
??. Epoxy resin transformer device
Shell security gadget: epoxy tar transformer shell fabric is made of stainless steel or aluminum combination. The degree of security comes to IP20 and IP23. The IP20 shell can avoid the passage of strong remote objects with a distance across more noteworthy than 12mm, and give assist security assurance for the transformer. The IP23 shell too avoids the influx of water beads inside an point of 60?? from the vertical line, and is appropriate for open air operation.
Temperature control and temperature show: The epoxy tar transformer temperature control framework is composed of a temperature controller and a PTC temperature measuring component introduced on the upper conclusion of the low-voltage winding, which is the most smoking point of the item, to realize temperature estimation and control of the transformer. If the temperature of the transformer winding is as well tall, the temperature controller will send out an caution flag, and it will naturally trip when the temperature surpasses the secure esteem. When constrained discuss cooling is utilized, the temperature controller decides the input or exchanging of the cooling fan concurring to the winding temperature. The temperature show framework straightforwardly shows the hot spot temperature of the winding amid the operation of the power transformer, and can be utilized in conjunction with the temperature control framework.
