Background technology
Generator is made up of rotor assembly, field frame assembly and excitation system, and wherein stator winding is the critical component of generator magnetic conduction conduction, and the form of stator winding directly determines the cost and the quality of a generator.Big capacity low pressure generator is owing to low-voltage, big capacity cause stator current very big, and existing low voltage generator adopts the copper bar stator winding, in each stator slot, puts into 2 circle stator winding, and every circle has 1～2 copper bar.For keeping the certain specific electric load of motor; Generator need be provided with more stator slot, and how number of stator slots had both increased the punching man-hour of stator heart sheet, the consumption that has also increased punch die; And copper bar quantity is increased, and increased the man-hour of the copper bar insulating bag mutual aid system devised for poor peasants, copper bar bending and welding.
Summary of the invention
The purpose of this invention is to provide that a kind of compact conformation, easy construction, reliability are high, the stator of the low voltage generator of increasing work efficiency greatly.
The present invention is achieved through following technical scheme:
A kind of big capacity low pressure generator unit stator; Comprise stator core; Said stator core endoporus is uniformly distributed with a plurality of stator slots, and setting-in is organized the stator coil winding more in the said stator slot, and said stator coil winding is that multiple coil that many enamelled wires and coiled one end inlet wire, the bring out line winding that looses is formed by multiturn, every circle; The diffusing winding of said multiple coil comprises that a plurality of profiles are identical, pursue the multiple coil that heavily increases from inside to outside, and each heavy coil is continuous through connecting pin each other; Stator slot radially is divided into inside groove, water jacket through insulating barrier along stator core; Two long limits of each heavy coil are inlaid in respectively in the inside groove and water jacket of corresponding two stator slots; Many group stator coil windings intersect each other distinguishes the full a plurality of stator slots of setting-in.
The object of the invention can also further realize through following technical measures.
Aforesaid big capacity low pressure generator unit stator is respectively equipped with the insulating barrier on each long limit of heavy coil of containing setting-in in the inside groove of wherein said stator slot and the water jacket, the notch of stator slot is squeezed into the sealing of insulation slot wedge.
The present invention has replaced existing low voltage generator copper bar stator winding with many enamelled wires and coiled one circle, lattice coil that each heavily the comprises multiturn winding that looses; Significantly reduced the quantity of coil; Reduce the notch number of stator core, reduced the manufacturing cost of stator; The present invention has cancelled welding point, has improved the reliability of stator coil winding; Compare with the copper bar stator winding, can reduce by 70～80% stator built-in line working hour, significantly improved the work efficiency that stator is made.
Advantage of the present invention and characteristics will illustrate through the non-limitative illustration of following preferred embodiment and explain that these embodiment only provide with reference to accompanying drawing as an example.
