Cast Resin Dry Type
Transformer |
|
| |
|
|
 The first cast-resin dry type transformer was produced by
SUNTEN in 1988. Up to now, SUNTEN has developed different generations of dry type transformer from series SC to
SC3-SCB3-SC(B)8-SC(B)9-SC(B)10-SC(B)H15. Additionally, SUNTEN has
developed special dry type transformer such as rectifying
traction transformer, excitation transformer, electric
furnace transformer, transformer for nuclear power
plant. In 2000, SUNTEN was awarded as the Most Famous
Chinese Brand
in the Transformer Industry by China
Investigation and Statistics Committee, China Commodity
Institute and China Quality Institute. Since 1992, SUNTEN
has retained the biggest domestic sales market share for dry
type transformer in China. |

SC(B)10-30~2500/10
three-phase resin insulation dry type
transformer is our new product which was
developed to adapt the national urban and rural
power gird reform, which meets the market
requirement and
improves the product performance and production
efficiency. This product is comply with the
requirements of State Standard GB/T10228.
According to the dry type transformer
performance code formulating principle,
SC(B)10 optimizes to reduce both no-load loss
and load loss based on the SC(B)8 and SC(B)9.
Additionally, it optimizes to design the
electromagnetic program and construction. It could be wildly used in
system up to 36kV such as electric power plant, power station,
industrial and mining enterprises, distribution
substation. |

Rectifying Traction Dry Type Transformer |
As the city became larger and
larger, the whole world pay more attention on
the heavy traffic and vehicle pollution issue.
Therefore, the urban subway is wildly used and
developed because of its large capacity, safety,
high speed and good environmental protect
effect.
SUNTEN aimed at this market and grasped the
opportunity to successfully develop and produce
the first 12-pulse rectifying traction
transformer. During the development of it, we
studied the features of transformer-rectifier
and cleared the relationship between the
rectifying rate of continuous voltage and the
parameter of transformers and rectifier. We
solved lots of technical problem such as the
balance of rectifying bridge and no-load voltage
rise. The 2500kVA model pattern we researched
and produces has passed the full on-load test.
We gained a lot of precious technique and
experience from it.
In 1997, in order to improve the
domesticalization and technical level of urban
railway transportation equipment, reduce
rectifying harmonic wave, improve the electric
network quality and join in international
competition, SUNTEN cooperated with several
units such as Shanghai Metro-subway three line,
Tianjin Electrified Railway Designing Institute,
Shanghai Rectifier Works,Guangzhou Metro-Subway
and so on. We based on the technique of 12-pulse
rectifier transformer and march to the advanced
24-pulse rectifying mechanism research, harmonic
wave content calculation, assembling unit system
full on-load test, assessment and design of
transformer phase shift method, balance,
exchange and reliability of two units of
transformer-rectifier, etc. We finished the
sample tral-produce and analog machine on-load
test and developed the 24-pulse dry type
rectifier transformer successfully. It filled
the domestic blank and reached the highest level
of the world present railway transportation
equipment. |
