The utility model has the characteristics of compact structure, low manufacturing cost, excellent heat dissipation performance, safe and reliable use and the like.
Description
Technical field
The utility model relates to a kind of combined transformer, relates in particular to a kind of combined transformer that uses in wind power generation.
Background technology
35kV used for wind power generation combined transformer is to be used in the wind-driven generator outlet, and voltage is boosted to the electric equipment that is connected to the grid behind the 35kV by 0.69kV; Mainly there is following technical problem in present domestic existing product:
1, generally oil is not filled with in employing, and the Oiltank structure of air gap is left on top, can't realize that gas, pressure protect and the air gap compensation oil volume effect of transformer is undesirable.
2, three-phase fuse is a vertical arrangement, and the oil temperature is inconsistent to the influence of three-phase fuse.
3, adopt strip-shape tap switch, the fuel tank volume is strengthened.
Summary of the invention
For solving the problems referred to above that exist in the existing used for wind power generation combined transformer, the utility model provides a kind of type used for wind power generation combined transformer that improves, and its technical scheme of taking is:
This transformer comprises the high-tension cable chamber, the operation with high pressure chamber, low voltage operated chamber, oil tank of transformer, its medium and high voltage cable chamber is positioned at the left side, operation with high pressure chamber and low voltage operated chamber are positioned at the place ahead, right side, oil tank of transformer is positioned at the rear, right side, the oil tank of transformer rear portion is provided with the elastic heat dissipating device, be provided with transformer body and high-tension fuse in the oil tank of transformer, the indoor high-voltage switch gear that is provided with of operation with high pressure, the low voltage operated indoor low-voltage cabinet that is provided with, high-tension cable is indoor to be provided with interconnective high pressure sensor, lightning arrester and bushing, the oil tank of transformer top is provided with the conservator that is communicated with oil tank of transformer, the oil tank of transformer top cover is provided with Buchholz relay and pressure switch, three-phase high-voltage fuse level is in the top of oil tank of transformer, and transformer shunting switch on one's body adopts cage type tapping switch.
The mode that adopts conservator to add the elastic heat dissipating device effectively realizes the compensation to oil volume, has realized protection and pressure protect; Buchholz relay and pressure switch can be realized uploading when transformer produces gas or pressure fault and report to the police or the jumping low tension switch.Three-phase fuse employing level is arranged, and makes the consistent Different Effects of transformer oil to fuse of having avoided of temperature of three-phase transformer oil of living in.Shunting switch adopts cage type tapping switch, and the volume of more efficient use oil tank of transformer has reduced the size of fuel tank.
Therefore the utlity model has compact conformation, production cost is low, excellent radiation performance, characteristics such as safe and reliable.
