Abstract

The invention relates to a pole coil and a preparation method thereof, aiming at providing an optimized design structure based on the original design of a rotor winding pole coil, and provides an improvement of a design method of a pole coil, which is simple in process, adopts an advanced making process, ensures the product quality, meets the requirements of the production process and adopts a new processing technique to meet the production and processing requirements, wherein innovative design is carried out on the design of original rotor winding pole coil leads and the pole coil leads are fixed by additionally forming a lead locating pin hole on the basis of the design of an original pole coil according to the structures of the pole coil leads, so as to avoid the phenomenon that the pole coil leads are thrown out caused by overhigh rotation speed of a rotor during running of a high-speed hydro-generator rotor winding pole coil. According to the invention, the labor intensity of operators in the assembling and making processes of a rotor winding is alleviated, the leads of the rotor can not be thrown out, safe and reliable running of the set is ensured, and the mounting working efficiency is improved.

Description

technical field [0001] The technical field of the hydroelectric generator of the present invention, in particular, relates to a magnetic pole coil and a preparation method thereof. Background technique [0002] The hydro-generator is always in rotation, the installation, design and assembly process of the rotor winding is complicated, and many other problems. The manufacturing industry of all hydro-generators is a high-tech traditional industry. During the operation of the high-speed hydraulic generator rotor winding magnetic pole coil contracted by our company, during the speed test, due to the high rotor speed, the inertia of the rotor coil lead wire and the connecting wire between the poles caused the coil lead wire and the coil insulation support to be damaged. Detachment will cause the lead wires of the rotor magnetic pole coil to be thrown out, resulting in a shutdown accident of the hydro-generator, and the rotor winding needs to be disassembled and repaired. Due to ...
