Description
Technical field
The utility model relates to a kind of combined transformer.Relate in particular to a kind of on-load voltage regulation point box combined transformer for wind power generation.
Background technology
Wind power generation, as a kind of clean reproducible energy, is more and more subject to the attention of countries in the world.And combined transformer is because the advantages such as its convenience with short production cycle, simple in structure, a less investment are widely applied.In application, there is following shortcoming in existing combined transformer for wind power generation:
1, the beautiful change of wind-powered electricity generation generally adopts off circuit tap changer to carry out voltage adjustment in high-pressure side, while needing voltage fluctuation that compensation network pressure drop or the fluctuation of load cause, need to cut off the load of whole piece circuit, and need special messenger to go manual adjustment to wind-powered electricity generation scene, it is very large that operating efficiency is affected by site environment, and adaptability is poor;
2, the beautiful high-voltage switch gear becoming of conventional wind-powered electricity generation and device body share an oil tank of transformer, the free carbon producing because of high side switch folding easily pollutes transformer oil, once there is to change the accident of transformer oil, need to change whole transformer oil, workload and maintenance cost are larger;
3, high-pressure side fuse damages need to change the molten cylinder of fuse time, emit most of transformer oil, and preventive maintenance time and cost are higher; Limited space, as user has that specific demand need to become that inside arranges that 80kVA blower fan dry becomes at case, UPS(uninterrupted power supply), when the components and parts such as measure and control device, case becomes space often has too many difficulties to cope with, and cannot meet user's variation requirement.
Summary of the invention
The problems referred to above that exist for solving existing combined transformer for wind power generation, the utility model patent provides a kind of novel wind power the beautiful arrangement becoming, and its technical scheme of taking is:
Comprise transformer room, high-tension cable chamber, low voltage operated chamber and low pressure maintenance chamber, the front portion, right side of high-tension cable chamber is located in low voltage operated chamber, transformer room is located at the rear portion, right side of high-tension cable chamber, low pressure maintenance chamber is located between high-tension cable chamber and low voltage operated chamber, the indoor transducer that is provided with of high-tension cable, lightning arrester and dry sleeve, low voltage operated indoor low-voltage cabinet and the low-tension bushing of being provided with, indoor high voltage load switch and the high-tension fuse of being provided with of low pressure maintenance, in transformer room, be provided with high voltage load switch fuel tank and the transformer body fuel tank of mutual isolation, transformer body is located in transformer body fuel tank, the body of on-load switch and high-tension fuse is located in high voltage load switch fuel tank, it is indoor that the front end of on-load switch and high-tension fuse is located at low pressure maintenance, the sub-connecting switch of transformer of being located at top, transformer room is seven gear on-load tap changers.
The low voltage operated indoor dry change of UPS, measure and control device and 80kVA blower fan that is provided with, wherein UPS and measure and control device are positioned at the left side of low-voltage cabinet, and the dry displacement of 80kVA blower fan is in the right side of low-voltage cabinet.
Sub-connecting switch of transformer of the present utility model adopts seven gear on-load tap changers, can be at any time, automatically adjust under the condition of not power-off, be convenient to the fluctuate output voltage that causes of compensation network pressure drop and fans load nonconforming, save cost of labor, improved the beautiful adaptability becoming of wind-powered electricity generation.Transformer body fuel tank and high-tension fuse, on-load switch fuel tank divide and are arranged, and high-voltage switch gear has taken an independent compartment, and the free carbon of having avoided fuse blows, on-load switch folding to produce pollutes device body transformer oil around.High-tension fuse and on-load switch fuel tank take up room less, have saved space and cost of investment, only need to change the transformer oil of little amount when internal transformer oil pollution need to be changed, and have reduced on-the-spot after-sale service amount and maintenance cost; Make full use of the space of on-load tap changer being installed and high-voltage switch gear being set separately, can do the installing space of elements such as becoming UPS, measure and control device at the reserved 80kVA blower fan of low-pressure chamber, and not need to increase again the space that case becomes.
The utlity model has compactness rational in infrastructure, production cost is low, the reliable feature of performance safety.
