Brief Description:
The products in this section are oil-immersed special transformer, used in three phase,50Hz,110kV and below 110kV
power system, are main power equipment in metallurgical industry,chemical industry, which transform power system
voltage into multi-phase AC voltage that rectifier need and change to DC power through rectifier for electrochemical, DECM,
electroplate, excitation, traction,etc. the below mentioned equipment are mainly used in the field of Metal electrolytic (such
as aluminum, manganese, copper,zinc,etc), chlor-alkali and graphitization,etc.
Model and its meaning
ZH------------(ZB means general industry),(ZH means Electrochemical electrolysis ),(ZD means electroplate),(ZT means
frequency control of motor speed),
S--------------(S means three-phase),(D means single-phase)
F--------------(F means wind cooling),(S means water cooling),no word means natural cooling
P--------------(P means Oil forced circulation), no word means oil natural cooling
T--------------(Z means with On-load tapping changer),(T means with regulating voltage ), no word means no tap changer or
off-circuit tap changer
K--------------K means in the tank built-in interphase reactor, if without K means without built-in interphase reactor
B--------------B means in the tank built-in saturable reactor, if without B means without built-in saturable reactor
630000------(KVA)means rated capacity, normally show the primary capacity according to actual capacity.
/110 ----------means rated voltage at primary side
Product structure characteristics:
Iron core: adopts High quality cold rolled oriented silicon steel sheet, All - diagonal multi - step ladder joint,tied up without
hole, clipped the Stainless steel drawplate with glass tape tightly.
Coil: winded with non - oxygen copper rod squeezed electromagnetic wire wrapped with high quality paper, insulate the
terminal by using company patent parts, multilayer brush stack end ring, to improve transformer short circuit withstand
capability. Adopts epoxy plates pressing device and increases the quantity of press button and stud to improve the
mechanical strength of the coil.
Oil tank: corrugated tank, no lifting core structure, the mechanical strength is high and appearance is beautiful. We have
open top type,bell type and semi-bell type,etc. the oil tank has foundation which conforms to national rail distance standard
and provide trolley for installation according to any customer's civil working requirements. The low voltage outlet busbar
adopts company patent big current Groove type outlet terminal to avoid leakage.
Safety protection device: according to relevant state and industrial standard, transformer can be equipped with oil
conservator, gas relay, pressure relief valve, thermometer, oil sampling valve and various gas vent and oil filling valves.
