Abstract
The utility model provides a stator lead-wire for a large-sized generator, which comprises a lead-wire body. The lead-wire body has a square cross section and is provided with an inner cavity therein. The hollow cavity has a circular cross section. The axial line of the lead-wire body with the square cross section and the axial line of the hollow cavity with the circular cross section are coaxial. The lead-wire body is made of oxygen-free copper.
Description
Technical field:
The utility model relates to the equipment that a kind of generator is used, especially a kind of high-rating generator stator lead.
Background technology:
In the prior art, technique known is the high-rating generator stator lead in usefulness, stator lead in usefulness generally is to adopt solid bar, the cooling of this bar lead-in wire body is to realize by circulation coolant in the slit between the bar, owing to will have insulating barrier to influence the flow velocity of coolant on the bar lead-in wire body, can not reach cooling effect preferably, this is the existing in prior technology weak point.
Summary of the invention:
The purpose of this utility model, be exactly at the existing in prior technology deficiency, and a kind of high-rating generator stator lead technical scheme is provided, and the body that cavity is arranged in this scheme employing foreign side is as the lead-in wire body, and the coolant of this lead-in wire body is to flow in cavity, therefore, the flow velocity of coolant is unaffected, has improved cooling effect, simultaneously because the lead-in wire body adopts square cross section, then increase conductive area again, improved the electrical efficiency of stator.
This programme is realized by following technical measures: include the lead-in wire body, the characteristics of this programme are that the cross section of described lead-in wire body is square, and this lead-in wire body has the body of cavity in being.The concrete characteristics of this programme also have, and the square of described lead-in wire body square cross section is square.Cavity in the described lead-in wire body is that cross section is circular cavity.Described cross section is that the axis and the described cross section of square lead-in wire body is the axis coaxle of circular cavity.The material that described lead-in wire body adopts is an oxygen-free copper.
The beneficial effect of this programme can learn according to the narration to such scheme, because the cross section of lead-in wire body is square in this scheme, this lead-in wire body has the body of cavity in being.This structure, the coolant that can make the lead-in wire body is to flow in the cavity of lead-in wire body, therefore, the flow velocity of coolant can not be affected, so improved cooling effect, be square cross section owing to what go between the body employing simultaneously, then increased conductive area again, improve the electric conductivity and the efficient of stator, also just improved the generating capacity of generator.This shows that the utility model compared with prior art has substantive distinguishing features and progress, the beneficial effect of its enforcement also is conspicuous.
Description of drawings:
Fig. 1 is the part sectional structure schematic diagram of the utility model embodiment.
Fig. 2 is the A-A sectional structure schematic diagram of Fig. 1.
Among the figure, 1 is the lead-in wire body, and 2 is cavity.
Embodiment:
For clearly demonstrating the technical characterstic of this programme,, and, this programme is set forth in conjunction with its accompanying drawing below by an embodiment.
By accompanying drawing as can be seen, the high-rating generator stator lead of this programme, cross section of its lead-in wire body 1 is square, this lead-in wire body 1 has the body of cavity 2 in being.The square of described lead-in wire body 1 square cross section is square.Cavity 2 in the described lead-in wire body 1 is that cross section is circular cavity 2.Described cross section is that the axis and the described cross section of square lead-in wire body 1 is the axis coaxle of circular cavity 2.The material that described lead-in wire body 1 adopts is an oxygen-free copper.
