Product Description

Product Description


WST series off-circuit Tap Changer (Linear form)
This kind of switch applies to the single-phase, three phase, combination oil-immersed transformer electrical power with frequency
of 50HZ, 60HZ, rated voltage of 10KV, 35KV, rated current of 30A~500A; the voltage-regulating mode are: central part, terminal
point ncutral point, which canbe dircctly fixed on the tank cover of the transformer, exchange under the off-circuit condition.

Model Explanation

W: off-circuit

S : three-phase or D for single phase

T : linear type tap chager

[ ]: voltage regulation model

[ ]: rated current

[ ]: rated voltage

[ ]: number of tapping heads

[ ]: number of tapping position
 

Voltage Regulation Model
I : terminal point
II : central point
III : neutral point
IV : Y-△ conversion
V : series-parallel connection

The usage scope and technical features of tube-type tap-changer:

    This is an new three- phase tube-type tap-changer,it is combined by the body of tap-changer and an operating turning framework, when the transformer is under non-energized state , we can turn over the tap position to change transformer ratio and stabilize output voltage,The single phase and " 1+2" phase tube-type tap-changer are suitable for installation on vertical direction,but the three-phase tube-type product is suitable for vertical or horizontal installation .  
  These series of products are specially designed for large or medium oil-immersed power transformer, full hermetically transformer or transformers for specially used , they are frequency normally on 50Hz or 60Hz, and suitable for flat type or bell-type oil tank , its Highest voltage for equipment is up to 252kV and below ,rated current up to 4000A and below.  This product has many technical features and owned a certain of national patent right protection .
(1) Simple and lively appearance ,reliable structure equipped with solid construct pieces .
(2) Light moment , turn over tap position clearly . The product has technical design features as following : body pieces are restricted each other and functioned each other ,you can change the tap position freely and exactly ,compared with the same type of products , it has obvious superiority features.
(3) No conductors and switch cover being equipped on the outer body of product . This is a full hermetially outer insulation screen which can withstand high voltage impulse .so no puncture discharge will rise between the narrow gaps , even if the air gap of the tap-changer is very near the active body of the transformer.
(4) The inner structure of the tube- type tap-changer can be drawn out as a whole part , this helps to installation and maintenance.
