2000KVA Oil-Immersed Transformer Introduction:
The 2000KVA oil-immersed transformer is a type of 2000KVA oil-immersed transformer that is widely used in the market. At present, there are many types of housings of our company’s 2000KVA oil-immersed transformers to meet the needs of different customers. At present, our company’s box transformer shell has aluminum-zinc embossed composite panels, ordinary composite panels, galvanized sheets, cold-rolled plates, stainless steel plates, glazed tiles, etc. The shell of ordinary composite board is inexpensive, and the heat insulation foam inside the box transformer shell produced by it can play a good thermal insulation performance and ensure that the electrical appliances inside can still work normally under the long-term exposure to the sun and high temperature of the box transformer. Galvanized sheet and stainless steel plate are made of 2000KVA oil-immersed transformer shell, which has strong oxidation resistance and strong metallic appearance. The transformer inside the box transformer adopts the current main S11 oil-immersed sealed transformer or SCB10 series dry-type transformer, the S11 series fully sealed oil-immersed transformer has a simple structure, good transformer sealing performance, and the insulating components in the transformer are not easy to be polluted by the external environment, resulting in the decline of the internal insulation performance of the transformer. S11 oil-immersed distribution transformer belongs to energy-saving and low-loss series distribution transformers. The core of this transformer is superimposed with high-quality cold-rolled grain-oriented silicon steel sheets, which greatly reduces the no-load loss of the transformer and the noise of the transformer during operation. Moreover, this kind of transformer is very cost-effective and is widely used at present. The 2000KVA oil-immersed transformer adopts an intelligent and modular design. The internal protection system of the box transformer adopts a microcomputer integrated automatic control device, and this automatic control device is distributed in the main electrical components and electrical circuits of the box transformer. Due to the use of advanced microcomputer automatic control device in the box transformer, we can realize the four remote functions of telemetry, remote control, shaking signal and remote adjustment inside the box transformer.
