Abstract
The utility model relates to a single/three phase conversion device for a synchronous generator. The device is characterized by consisting of a generator output cabinet, a single/three phase conversion cabinet, a high voltage cable and an intermediate transformer. The phase b of the intermediate transformer is short-circuited by low voltage, so that the intermediate transformer realizes single-phase output at the same time. When inductive test for products in the level of 110kV and above is performed by the synchronous generator, a single-phase power supply is required, and meanwhile, the three-phase intermediate transformer is required to be short-circuited to realize single-phase output. According to the device provided by the utility model, through only one step, the output of the generator is converted to single-phase output and one phase of the intermediate transformer is short-circuited by low voltage, so that the intermediate transformer realizes single-phase output at the same time. The problem that frequent conversion between a single-phase power supply and a three-phase power supply for existing generators is overcome. The device provided by the utility model is mainly applied to test of transformers in the level of 110kV and above.
Description
(1) field under
The utility model relates to a kind of single three-phase inversion device of synchronous generator, belongs to field transformer.
(2) backgroundTechnology
Synchronous generator by three-phase inversion be single-phase after, also need to carry out independent short circuit to middle transformer, energized conductor is exposed outside, uncertain factor is higher; If intermediate transformer can not in time be opened when three-phase operation, as easy as rolling off a logly cause the testing equipment short circuit, have an accident.After using this device, in high-voltage board, change structure single, the three-phase inversion disconnecting link, make two cables while short circuits that output to intermediate transformer, reached the externally middle effect that becomes of short circuit.
(3) inventionContent
For overcoming the deficiencies in the prior art, the utility model provides generator list three-phase inversion device a kind of simple in structure, safe and reliable, easy to operate.
The technical solution of the utility model is:
A kind of single three-phase inversion device of synchronous generator is characterized in that: be made of generator output counter, single three-phase inversion cabinet, high-tension cable and intermediate transformer, described intermediate transformer low pressure short circuit one phase becomes single-phase output simultaneously in the middle of making.
The beneficial effects of the utility model are: through application in practice, solved the difficult problem of three phase mains and single phase poaer supply frequent transitions the utility model, and simultaneously middle transformer has been changed, this device all is enclosed in the high-voltage board, improve coefficient of safety, saved production cost; It can carry out the mutual conversion of single three phase mains easily, and is convenient and swift, safe and reliable, has improved production efficiency; When using synchronous generator to carry out the induced test of 110kV and above electric pressure product, require single phase poaer supply, to carry out the single-phase output of short circuit to the three-phase intermediate transformer simultaneously; This utility model only needs single stepping to convert generator to single-phase output again simultaneously intermediate transformer low pressure short circuit one phase, becomes single-phase output simultaneously in the middle of making.This utility model is mainly used in the transformer test of 110kV and above electric pressure.
(4) description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is conventional single three-phase inversion manipulated or operated apparatus;
Fig. 2 is the utility model list three-phase inversion manipulated or operated apparatus;
Among the figure, 1 generator output counter, 2 single three-phase inversion cabinets, 3 high-tension cables, 4 intermediate transformers, 5 intermediate transformer short circuit disconnecting links.
(5) embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.This embodiment is a kind of single three-phase inversion device of synchronous generator, it is characterized in that: be made of generator output counter 1, single three-phase inversion cabinet 2, high-tension cable 3 and intermediate transformer 4, described intermediate transformer 4 low pressure short circuit b phases become single-phase output simultaneously in the middle of making.
The utility model has been cancelled centre in conventional single three-phase inversion device and has been shortened and connect disconnecting link 5.Accompanying drawing 1 is conventional single three-phase inversion manipulated or operated apparatus, after carrying out generator list, three-phase inversion, also need externally to carry out short circuit separately with single-phase disconnecting link to middle transformer, by this invention can be when generator be changed short circuit intermediate transformer 4 low pressure b phases; Become single-phase output simultaneously in the middle of making.Through application in practice, the utility model has solved the difficult problem of three phase mains and single phase poaer supply frequent transitions effectively, and simultaneously middle transformer is changed, and this device all is enclosed in the high-voltage board, has improved coefficient of safety, has saved production cost; It can carry out the mutual conversion of single three phase mains easily, and is convenient and swift, safe and reliable, has improved production efficiency; When using synchronous generator to carry out the induced test of 110kV and above electric pressure product, require single phase poaer supply, to carry out the single-phase output of short circuit to the three-phase intermediate transformer simultaneously; This utility model only needs single stepping to convert generator to single-phase output again simultaneously intermediate transformer low pressure short circuit one phase, becomes single-phase output simultaneously in the middle of making.This utility model is mainly used in the transformer test of 110kV and above electric pressure.
Claims (1)
1. single three-phase inversion device of a synchronous generator, it is characterized in that: constitute by generator output counter (1), single three-phase inversion cabinet (2), high-tension cable (3) and intermediate transformer (4), described intermediate transformer (4) low pressure short circuit b phase becomes single-phase output simultaneously in the middle of making.
