1000KVA 10/0.4KV Oil Power Transformer
The oil immersed transformer adopts three-dimensional wound iron core. Because its three iron core pillars are arranged in equilateral triangle three-dimensional, the winding is tight, the three magnetic circuits have the same length, and the magnetic circuit has no air gap. Shortest, core leg cross-sectional area closer to circular, further improving performance, reducing losses, reducing noise, balancing three terms, and reducing third harmonic components. But due to the pressure regulating switch being inside the water tank. When adjusting the pressure, the contacts of the switch cannot be seen from outside. There are two types of reaction phenomena: poor contact and open circuit. If the contact is not good, it is easy to burn out the switch when the load is too large.
Products peature
1. The coil adopts a low axial short-circuit force structure. When the transformer is short-circuited, it can greatly reduce the axial short-circuit force and greatly improve the ability of withstanding short-circuit.
2. All the bolts and nuts on the cover surface are made of 304 stainless steel, which enhances the rust prevention ability of the transformer.
3. Each sealing rubber ring adopts the best rubber material in China, which greatly prolongs the service life of the sealing rubber ring.
4. The transformer body adopts a high-reliability support structure to ensure reliable compression of the upper and lower parts of the coil. The entire body structure improves the ability of withstanding short-circuited.
5. This not only reduces the no-load loss of the transformer, but also ensures that the core flux is not saturated when the transformer is operating under voltage, so that the third harmonic of the transformer is small.
