KS9 series

Features of Products

　　 As one kind of distributing transformer for mining use, KS9 series transformer has many advantages, such as compacted body,
reasonable structure, Iow in spoilage, good in heat-dispersion and, easy to go into a well.
　　This series of product adopt high-permeance cold-rolled grain-oriented silicon-steel plate of high-quality. The iron core applies
echelon form iterative accumulation. The core pole which is multilevel circular cross-section can ensure of Iow noise and Iow spoilage.
The structure of gasoline tank is very firm. Both side of tank are welded with cable junction boxes of high and Iow voltage which are
used for wiring. High-voltage loops need tapping voltage that is ±5% of rated voltage. It is using the tap switch to change the voltage.
When the voltage exchanges, the power must be cut off fist, then unveil the wind-rain cover on the tap switch to counterchange the
voltage. The Iow voltage side of the transformer can be connect the type’Y’ of 693V or the type "D" of 400V to supply power. And
inside the cable junction box has a secondary terminal which educes six insulators for users’ option. The joint hinges that welded
on the casing are available and drawing crow-plate is mounted beneath the base. There are mounting holes in the drawing crow-plate
used for being addly-installed with mine-car’ contact roller whenmine needing.

Practicable Confines

　　The oil-immersed distributing transformer is applied to the capacity 630KVA or below, and the voltage
10KV or below. This product is normal one which has norequirement of explosion - proof. The main function
of the product is for mine illumination when distributing power for mining as well as for the driving power.
This series of transformers will not need lift-machine examination after transportation. It is allowed to
assemble the unshipped spare parts for checking and acceptance.

Comply Standards

Standards for this series of product：
GB1094.1~2-1996, GB1094.3,5-2003, GB/T6451-1999, GB12173-1990o

Using environment and working condition

1、The installment highly does not surpass elevation 1000m,the special environment gives the explanation in addition;
2、Ambient temperature:
　　Highest air temperature +40℃;
　　Highest daily average air temperature+25℃;
　　Highest annual average air tempera ture+20℃;
　　Lowest outdoor air temperature-20℃.
3、The surrounding air relative hurnidityis not bigger than 95% (+25℃when.
4、Installs under the mine pit although has the coal dust, the gas ,but non-explosion hazard place;
5、The supply voltage profile is approximate to the sine wave;
