The invention relates to a composite post insulator core rod and fitting thermal shrinkage assembly process and special equipment. According to the assembly process, the heating plates and the adapter plates of the positioning devices at the movable end and the fixed end are correspondingly installed with flanges of the corresponding to-be-machined flange hardware fittings in an aligned mode and locked through screws. The insulating core rod to be machined is placed on a fine adjustment supporting frame of the supporting platform to be horizontal, the insulating core rod to be machined is slowly aligned to an inner cavity of the flange hardware fitting to be machined by adjusting the fine adjustment supporting frame, and at the moment, the central axis of the two flange hardware fittings to be machined at the movable end and the fixed end and the central axis of the insulating core rod to be machined are located on the same straight line; starting a heating plate to heat the two to-be-processed flange fittings, and stopping heating until the surface temperatures of the two to-be-processed flange fittings are slightly lower than the maximum heating temperature; and the positioning device at the moving end is driven to run in the assembling direction until the to-be-machined insulating core rod and the to-be-machined flange fittings at the two ends are assembled in place. And the coaxiality of the insulator core rod and the hardware fitting is improved.
Description
technical field [0001] The invention belongs to the technical field of power station pillars, and relates to a composite pillar insulator mandrel and a metal fitting heat shrinkable assembly process and special equipment. Background technique [0002] With the rapid economic development, my country's market demand for power resources is also increasing year by year. At the same time, with the development of economy and the increase of electricity load, the problem of excessive short-circuit current in various regional power grids under the existing voltage level has become increasingly prominent, jeopardizing the safe and stable operation of the power grid. Therefore, on the basis of the wide application of ultra-high voltage transmission projects, my country's ultra-high voltage transmission technology has also developed vigorously, and the technology has gradually matured, making great achievements in large-scale long-distance transmission. [0003] In EHV / UHV substations...
