Abstract
Provided is a combined transformer which can be operated under the excitation or the on-load state and which regulates the voltage through the switching winding tap position. The utility model is of a cuboid shape and is composed of a transformer body, an oil tank and a switch device etc. In the oil tank, each high voltage winding phase line is respectively in electric connection with the homonym phase high voltage cased well through a lead wire. When the voltage of the power network is not stable, the utility model can change the transformation ratio of the transformer through adjusting the gear of the on-load voltage regulation tap switch under the excitation or the on-load state, thus changing the secondary voltage of the transformer to the rated value.
Description
Technical field
The utility model relates to a kind of combined transformer, especially can operate under excitation or load condition, switches the on-load voltage regulation combined transformer that the winding tap position carries out pressure regulation.
Background technology
At present, known combined transformer is selected for use is at secondary bringing onto load not, and once under the state that also disconnects with electrical network, the tap of conversion transformer is to change the non-excitation pressure adjustment mode of transformer voltage ratio.Obviously, general non-excitation pressure adjustment combined transformer can not have a power failure or have at transformer under the state of excitation and bringing onto load electric current at some and just can not use.
Summary of the invention
In order to solve existing combined transformer the deficiency that can't use under the state of excitation and bringing onto load electric current is arranged in inaccurate power failure or at combined transformer, the utility model provides a kind of on-load voltage regulation combined transformer, profile is cuboid, is made up of transformer body, fuel tank and switchgear etc.This combined transformer can have excitation and having under the load current state, changes the voltage ratio of transformer by the gear of adjusting on-load tap changer, makes the combined transformer operate as normal.
The technical scheme that its technical problem that solves the utility model adopts is: in fuel tank, a three-phase transformer device body and on-load tap changer are set, every phase high pressure winding phase line is electrically connected by lead-in wire respectively with famous prime minister's bushing well.When fluctuation appears in line voltage, change the transformation ratio of transformer with the gear of adjusting on-load tap changer, thereby make the voltage of step down side output keep rated value, make combined transformer realize operate as normal.
The beneficial effects of the utility model are: the on-load voltage regulation combined transformer all can be adjusted the transformation ratio of transformer under no excitation or on-load voltage regulation state, enlarges the scope of application of combined transformer, and is safe in utilization, reduces probability of failure, increases operational reliability.Scheme is easy, practical, easy to operate.
