200KVA Transformer

The S11-M-200KVA transformer adopts a fully oil-filled sealed type without an oil storage tank. Due to changes in temperature and load, the oil volume of the transformer is completely adjusted by the elasticity of the transformer oil tank. Its no-load loss is 30% lower than S9, and it has strong lightning impact and short circuit resistance. The energy-saving effect is more obvious, and the external size of the transformer is reduced. It is currently a new energy-saving product in China. The average annual reduction in no-load loss is 10%, and the average reduction in load loss is 20%.

The most common 10KV S11 oil immersed transformer models are as follows: S11-M-30/10, S11-M-50/10, S11-M-63/10, S11-M-80/10, S11-M-100/10, S11-M-125/10, S11-M-160/10, S11-M-200/10, S11-M-250/10, S11-M-315/10, S11-M-400/10, S11-M-630/10, S11-M-800/10, S11-M-1000/10, S11-M-1250/10, S11-M-1600/10, S11-M-2000/10, S11-M-2500/10

1、Model Meaning

S11-M - □/□ Low loss power transformer model meaning:

S: Represents a three-phase transformer

11: Performance level code

M: Represents fully enclosed

□/□: respectively represent the rated capacity KVA/voltage level

The performance of S11-M 200KVA 3 phase transformer meets the national standard GB1094-1996 "Power Transformers" GB/T6451-1999 "Technical Parameters and Requirements for Three-phase Oil Immersed Power Transformers". The iron core is made of high-quality cold-rolled silicon steel sheets, with stepped three-level seams and surface coated with curing paint, reducing losses and noise; The coil is wound with high-quality oxygen-free copper wire, and the heat dissipation adopts a new oil channel structure. The design is reasonable, and the insulation process is optimized to improve mechanical strength and short-circuit resistance. The appearance is beautiful and elegant, and the operation is reliable. Widely used in substations and urban and rural power grids.

2、Product Features:

1. The core of S11-M-200KVA transformer is a seamless and non graded nearly pure circular cross-section made of silicon steel strip material. The iron yoke and iron core column are connected with rounded corners, and the iron core is in a closed shape.

2. The high and low voltage coils of the power transformer are directly wound on the iron core, with good concentricity and short-circuit resistance.

3. Due to the special structure of the 200KVA 3 phase transformer core, which is made of high-quality cold-rolled silicon steel sheets with crystalline orientation and annealed, the no-load loss of the S11-M 200KVA transformer is reduced by 30%, the no-load current is reduced by 70%, and the noise is reduced by about 8 decibels compared to the same capacity S9 type.

4. Cancel the oil storage tank. Using a corrugated plate oil tank, the temperature induced oil volume change is adjusted by the elasticity of the corrugated plate to isolate the transformer oil from the air and prolong the service life.

5. The use of corrugated oil tanks for temperature rise occupies a small area and has a beautiful appearance.

6. Fully mechanized iron core processing reduces labor intensity, improves product quality, and stabilizes quality.
