Abstract

The invention provides a new construction method. In accordance with the characteristics of a structural design technical scheme of temporarily fixing upper and lower layers of winding bars, avoiding generation of distortional stress and forming an ideal filling channel, the construction steps, method and requirements are specified, the process steps are perfected, and the epoxy glue filling quality is ensured, so that a practical product achieves the effect that the end leakage reactance is minimized and the end structure is firm, reliable and stable, thus solving the problem that the product can not meet the design requirements and service life requirements due to incapability of ideally implementing the scheme in the prior art.

Description

technical field [0001] The invention relates to a construction method for a stator end structure of an impact generator. Background technique [0002] The impact generator is different from the conventional generator. Its operating characteristic is that the entire operating condition is in a transient process of sudden short circuit, which is equivalent to the accident condition of the conventional generator. The structural design should ensure that the generator can provide the large current, the stator end structure should be able to withstand frequent and huge electrodynamic shocks, and have high reliability during the service life of 30 to 40 years; as described in the patent 'Impact Generator ZL200710144310.0', the patent ' The structure proposed by the impact generator ZL200710144310.0' should adopt suitable construction methods, such as 'Stator winding end assembly process ZL200810064096.2'. [0003] The stator winding end structure described in the patent 'Impact G...
