Abstract
Disclosed is a combined transformer which works under a single-phase power supply system and no-excitation voltage regulation status. The transformer has a cuboid shape and consists of a single-phase transformer body, an oil tank and a switchgear, etc. The single-phase transformer body is arranged in the oil tank while a high voltage winding end A is electrically connected to a high voltage casing well A via a lead and a high voltage winding X end is electrically connected with a high voltage well X via a lead. When the power network voltage fluctuates, under the no-excitation voltage regulation status, a transformation ratio of the single-phase transformer can be changed by adjusting the gear of a single-phase no-excitation voltage regulation tap-changer so that the single-phase transformer can output a normal rated voltage.
Description
Technical field
The utility model relates to a kind of combined transformer, especially can carry out the single-phase non-excitation pressure adjustment combined transformer of work under single phase poaer supply electric power system, non-excitation pressure adjustment state.
Background technology
At present, known combined transformer is the three phase combined transformer that carries out work under three phase mains electric power system, non-excitation pressure adjustment state, and the use occasion of this transformer has certain limitation.In the practice, under the occasion of numerous single phase poaer supply power supplies, general three phase combined transformer just can not use.
Summary of the invention
In order to solve the deficiency that existing three phase combined transformer can't use under single phase poaer supply electric power system, non-excitation pressure adjustment state, the utility model provides a kind of single-phase non-excitation pressure adjustment combined transformer, profile is cuboid, is made up of single-phase transformer device body, fuel tank and switchgear etc.This combined transformer can convenient use under the state of single phase poaer supply electric power system, non-excitation pressure adjustment.
The technical scheme that its technical problem that solves the utility model adopts is: in the fuel tank of combined transformer, one single-phase transformer device body and single-phase non-excitation pressure adjustment shunting switch are set, high pressure winding A end is electrically connected by lead-in wire with bushing well A, and high pressure winding X end is electrically connected by lead-in wire with bushing well X.When fluctuation appears in line voltage, under no excited state, change the transformation ratio of single-phase transformer by adjusting single-phase non-excitation pressure adjustment shunting switch gear, thereby make single-phase transformer can export normal rating voltage.
The beneficial effects of the utility model are: single-phase non-excitation pressure adjustment combined transformer can be used safely under the state of single phase poaer supply electric power system, non-excitation pressure adjustment, enlarge the scope of application of combined transformer, the power transformer threephase load balance of previous stage is distributed, reduce probability of failure, increase the powered operation reliability.Scheme is easy, practical, easy to operate.
