Oil-immersed transformer

35KV and below level three-phase oil-immersed power transformers

Overview

As the main power transformation equipment of medium and small-sized substation, this product is applied to 3-phases, 50Hz,35kV class and below electric power systems. It is used for industrial and agricultural power distribution, motive power and illumination. Our company absorbs domestic and foreign advanced technologies, adopts new materials and optimizes the design. As a result, the product becomes more reasonable, and electrical strength, mechanical strength and heat dissipation capability of the product have been abviously impored.

- GB1094.1~2-1996 Power transformer
- GB1094.3,5-2003 Power transformer
- Technical parameters and requirements of GB/T6451-2008 three-phase oilimmersed power transformer
Performance characteristics
- All high-voltage windings are of multilayer cylinder structure and impulse voltage distribution of windings is improved.
- For low-voltage windings whose capacities range from 630 to 3,150kVA, cylinder or spiral type structure is adopted. With high mechanical strength and balanced distribution of ampere-turns, the product has strong capacity against short circuit.
- The body is additionally equipped with positioning mechanism in order to avoid displacement during transportation; in the meantime, all fasteners are additionally equipped with retaining nuts to guarantee that fasteners are not loosened during long-term running; moreover, the requirement of no pendant-core examination is satisfied.
- The iron core is made by laminating the inclined joints of high-quality cold-rolled grain orientated silicon steel sheet. The transformer adopts vacuum oil filling.
- After carrying out degreasing, derusting and phosphating, the product surface shall be sprayed with prime coat and non-paint. As a result, the product can satisfy the special operation requirements of metallurgy and petrifaction system as well as moist and dirty areas. With good-looking appearance, small volume and small occupied area for installation, all series of products are the ideal maintenance-free products.
- Small-volume transformer tank adopts corrugated plate and has respiratory function through which oil volume change caused by temperature change is compensated. As a result, transformer height is decreased and insulation property reduction is prevented effectively by avoiding the entering of oxygen and moisture.
