tap changer Off-circuit cage-form tap-changer for transformer off circuit tap changer
Application
The specification of the product is rated voltage 110kV(highest vltage for equipment 126kV) and below,rated current 2000A and below with various regulating methods can apply hand-operation and power-driven on the cover or side of the transformer.
WSL Series off-circuit tap changer is used for oil-immersed transformer with on-load tap changer.It is usually of cage type structure.The switch transition type is variable with its inner structure.It has linear regulatiing,single-bridge stridden over connection,double-bridge stridden over connection,Y-Δ transition,series-parallel connected transition,positvie or reverse regulation ate.This tape changer is classified into two type,one called tank head type,the other called bell covered type.The operation method can be classified into two type,one is handled on the tank head or to the grounding,the other is driven with motor,They are used for power transformer,rectification transformer or furnace transformer in following specification range,rated frequency with 50Hz or 60Hz,highest voltage for equipment with 40.5kV,72.5kV and 126kV,rated current with 250A-2000A.This type of tap changer can only be operated in transformer under non-energized condition.
Technical parameters
Off-circuit Tap-changer with Linear Type
This instruction is the brief introduction of the linear off-circuit tap-changer. The flange and lifting board of it are fixed on the transformer cover, the function for the tap-changer is that we can operate the tap-changer on the transformer cover, by regulating the tap position to realize the voltage regulating of transformer as required. But only after the transformer is cut off from the electrical network, when the transformer is under off-circuit state, could we operate this type of tap-changer.
