5results about How to "Reduce maintenance difficulties" patented technology

The invention discloses a replacement and maintenance device for a high-voltage fuse and a fuse cylinder, and relates to the technical field of high-voltage fuses, the replacement and maintenance device comprises a supporting rod, and the top of the supporting rod is fixedly connected with the fuse cylinder. According to the utility model, the two positioning clamping plates move relatively to clamp the two sides of components such as a fuse, a stabilizer and a driver so as to prevent displacement during subsequent workpiece detection, and the relative movement of the two positioning clamping plates can accurately clamp the fuse, the stabilizer and the driver so as to prevent the fuse, the stabilizer and the driver from displacement during the maintenance or replacement process. Therefore, it can be guaranteed that the workpiece is kept at the correct position in the whole process, errors or damage caused by position deviation is reduced, the assembly is prevented from moving accidentally in the replacement or maintenance process, and potential risks to operators are reduced.

The invention discloses a method for solving the problem that multiple layout libraries with the same name are mutually strung, and relates to the technical field of data processing. Comprising the following steps: analyzing a design hierarchical structure of a top layer in a design library, identifying and capturing all cells from the top layer to the bottommost layer, and generating a list; establishing a new cell library according to the generated list, and copying all cells to the new cell library according to new names; entering a new cell library, processing the current hierarchy for each cell, and replacing all cell names with new names in the new cell library according to the list; according to the method, the hierarchical structure of a design library is captured recursively, a complete hierarchical tree is established, the information of each cell is recorded comprehensively, the problems of naming conflict and cross-library reference of cells with the same name in different libraries or hierarchies are solved through classification and renaming, the consistency of the same cell in different libraries is ensured through systematic analysis and redistribution, and the consistency of the cells in different libraries is ensured. And the problem of view inconsistency is avoided.

This invention discloses a multi-roller winding device for high-voltage bushing capacitor cores, including a winding roller, a winding heating roller mechanism disposed on both sides of the winding roller, and a winding lifting mechanism that drives the winding roller to lift. The winding heating roller mechanism includes two heating rollers symmetrically disposed on both sides of the winding roller and multiple sets of clutch adjustment mechanisms arranged along the length of the heating roller and adjusting the distance between the two heating rollers. Oil circulation temperature control devices are respectively installed at both ends of the winding roller. This invention is rationally designed, connecting two oil circulation temperature control devices to two heating rollers to form a circulating heating circuit, ensuring the temperature of the heating rollers and further ensuring the dryness of the capacitor core during winding. Simultaneously, multi-roller collaboration is employed during winding, with both the winding roller and the heating roller having winding power, collaboratively completing the winding of the insulating paper in the capacitor core, ensuring stable and tight winding of the insulating paper, and improving the performance of the capacitor core.
