S13-M oil-type transformers
S13-M oil-immersed distribution transformers for the distribution network and industrial and mining enterprises in the power supply and distribution system in the important equipment Transformer in the industrial and mining enterprises in various regions of the country, agriculture and civil construction can also be used in petroleum, chemical industry, Multi-chemical substances.
Capacity in the 630 ~ 2000kvA range of low-voltage windings with cylindrical or spiral structure, high mechanical strength, ampere-turn distribution balance, the product of good short-circuit resistance.
S13-M oil-immersed transformer body to add the positioning structure, so that in the transport process does not produce displacement, and all fasteners with fastening nuts to ensure that products in the long run is not loose during the fasteners to meet the Not hanging core requirements.
S13-M oil-immersed transformer uses a corrugated oil tank, cancel the oil conservator, cover and box along the complete death or bolt fastening, extending the service life of transformer oil.
S13-M oil-immersed transformer surface to the oil, to embroidery, phosphate coating after spraying primer, topcoat, to meet the metallurgical, petrochemical and wet pollution areas of special use requirements.
Selection of components, using a sealed transformer tank, according to standard requirements to install a pressure relief valve, signal thermometer, gas relays, etc., to ensure the safe operation of the transformer. The series of products beautiful shape, small size, can reduce the installation area, is the ideal maintenance-free high-quality products.
S13-M oil-immersed transformer use of the environment: outdoor / indoor use
Normal use conditions: altitude of not more than 1000m.
Ambient temperature up to +40 ℃, the lowest -25 ℃,
The annual average temperature +20 ℃
Special environment Conditions of use: Elevation above 1000m.
Ambient temperature up to +40 ℃, the lowest -45 ℃.
Technical parameters and requirements for three - phase oil - immersed power transformers GB / T
Performance characteristics of S13-M oil wetting transformer
A, oil-wet transformer low-voltage windings are generally cylindrical structure or spiral structure; high-voltage winding multi-cylinder structure, so that the distribution of the winding ampere-balanced, small magnetic leakage, high mechanical strength, short circuit resistance Strong.
B, the core and winding each with a tightening measures, height, low voltage lead and other fastening parts are with self-locking lock nut, the use of non-hanging structure, can withstand the transport of the earthquake.
C, coil and core using vacuum drying, transformer oil vacuum oil and oil filling process, so that the moisture inside the transformer to a minimum.
D, S13 transformer tank with corrugated film, which has a respiratory function to compensate for temperature changes caused by the volume of oil changes, so the product does not have oil conservator, obviously reduced the height of the transformer.
E, because the corrugated plate to replace the oil conservator, so that the transformer oil and the outside world isolation, thus effectively preventing the oxygen, moisture into the resulting insulation performance decline.
F, according to the above five points to ensure that the oil-wetted transformer in the normal operation does not require oil, greatly reducing the maintenance cost of the transformer, while extending the service life of the transformer.
