Description
Technical field
The utility model relates to technical field of electric equipment, is specifically related to a kind of novel dry-type transformer.
Background technology
The places such as dry-type transformer is widely used in localized lighting, skyscraper, airport, harbour CNC plant equipment, briefly dry-type transformer just refers to that iron core and winding are not immersed in the transformer in insulating oil.The type of cooling is divided into natural air cool (AN) and force Air flow (AF).During natural air cooling, transformer can run continuously for a long time under rated capacity.During forced air cooling, transformer output capacity can improve 50%.Be applicable to interrupted running overload, or emergent accident running overload; Because load loss during overload and impedance voltage amplification are comparatively large, are in non-economy running status, therefore it should not made to be in long-time continuous running overload.
Current, urban and rural power grids pace of construction accelerates, and China's energy output and power consumption grow with each passing day.Typically, often increase the energy output of 1kW, need the transformer total capacity increasing 11kVA; And wherein Satons distribution transformer accounts for the 1/3-1/2 of whole transformer total capacity.According to estimates, dry-type distribution transformer accounts for the 1/5-1/4 of whole distribution transformer.By pulling of electrical network construction investment, the transformer industry degree of prosperity is higher, and after 2010, output is by the speedup of maintenance about 20%.According to historical experience and the change of transformer voltage hierarchical organization, distribution transformer ratio is about 40%, and the ratio according to 40% calculates, and China increased dry-type transformer output newly and will reach about 200,000,000 KVA this year.
The dry-type transformer type of cooling is divided into natural air cool (AN) and force Air flow (AF).During natural air cooling, transformer can run continuously for a long time under rated capacity.During forced air cooling, transformer output capacity can improve 50%.Be applicable to interrupted running overload, or emergent accident running overload; Because load loss during overload and impedance voltage amplification are comparatively large, are in non-economy running status, therefore it should not made to be in long-time continuous running overload.Current dry-type transformer cooling structure design is on the market unreasonable, can not reach good cooling effect, affect the normal operation of transformer.
