The application provides a closed disconnecting switch with ice breaking function, which comprises a first static contact assembly, a second static contact assembly and a movable contact blade assembly connecting the first static contact assembly and the second static contact assembly. One end of the movable contact blade assembly is rotatably connected with the first static contact assembly, and the other end of the movable contact blade assembly can be separated from or contacted with the second static contact assembly, so as to realize the opening and closing of the disconnecting switch. The closed disconnecting switch with ice breaking function reduces the ice thickness of the joint between the movable contact blade assembly and the first static contact assembly through the sealing design. On the other hand, the opening and closing function is realized by the rotation of the movable contact blade assembly around the first static contact assembly, and the ice at the joint between the first and second insulating housings is cut by the knife edge formed by the edge of the second insulating housing used for cooperating with the first insulating housing, so that the ice breaking capacity is improved.

This invention belongs to the field of grinding and surface finishing technology, and relates to a follow-up resonant grinding and foreign matter removal device and process for power supply cables. The device includes a precision resonant actuation mechanism, a contour grinding head, a grinding impedance detection unit, and a frequency conversion grinding control center. Based on the electromechanical coupling impedance signal, the control center tracks the mechanical resonant point through phase-locked logic and adjusts the drive signal frequency, so that the contour grinding head with its segmented, clamping structure is in a resonant grinding state with the foreign matter on the surface of the power supply cable. The high-frequency vibration of the inner abrasive layer performs micro-cutting and shearing peeling of the foreign matter; and adaptive mode switching is achieved based on the dynamic characteristics of the impedance spectrum. This invention achieves non-destructive precision micro-grinding, efficiently removes ice buildup and improves the surface finish of the workpiece, avoiding damage from traditional rigid scraping, and is suitable for cleaning the surface of power supply cables such as cables.

This invention discloses an asphalt concrete that combines ice-breaking and noise reduction with its manufacturing method, comprising the following raw materials by weight: 100-120 parts aggregate, 5-8 parts thermally conductive asphalt, 2-8 parts mineral powder, and 3-5 parts noise-reducing filler. The aggregate, noise-reducing filler, and mineral powder are stirred for 20 seconds, then the thermally conductive asphalt is added, mixed, and shaped to obtain the asphalt concrete that combines ice-breaking and noise reduction. Modified silicon carbide is introduced into the thermally conductive asphalt, with carbon nanotubes as the carbon source, silicon powder and silicon dioxide as the silicon source, and cobalt acetate as the cobalt source. Modified silicon carbide is prepared by solid-state sintering, in which cobalt atoms enter the silicon carbide lattice to prepare cobalt-doped silicon carbide. While silicon carbide itself has excellent thermal conductivity, the introduction of cobalt gives the modified silicon carbide magnetism and improves its microwave absorption performance. Under microwave action, it can quickly melt snow and break ice, and also improves the thermal conductivity of the asphalt, further improving the ice-breaking performance.
