Technical Field

[0001] The present invention relates to the technical field of high-voltage electrical equipment, and particularly to a drop-type fuse and a casting tool for fuse ceramics. Background Art

[0002] Fuse ceramics are devices installed between conductors at different potentials or between conductors and grounding components, and can withstand the action of voltage and mechanical stress. There are various types and shapes of fuse ceramics. Although the structures and outer shapes of different types of fuse ceramics are quite different, they are all composed of two major parts: insulating parts and connecting fittings. Fuse ceramics are a special type of insulating control device and can play an important role in overhead transmission lines. In the early years, fuse ceramics were mostly used on telegraph poles. Slowly, many disc-shaped insulators were hung at one end of the high-type high-voltage wire connection tower. It is used to increase the creepage distance and is usually made of glass or ceramics.

[0003] The existing fuses include fuse ceramics and fittings fixed in the orifices at both ends and on the outer wall of the fuse ceramics. The fittings and the fuse ceramics are fixed by cement casting; when the fuse ceramics and the fittings are assembled and cast, they need to be fixed by using a fixture first to make the axis of one end of the fitting coincide with the axis of the orifice of the fuse ceramic, so as to ensure the stability of the connection between the fitting and the fuse ceramic. However, when the existing fuse ceramics are installed on the fixture, manual adjustment is required to align them with the fittings. The cooperation between the fuse ceramics and the installation fixture is inconvenient, resulting in low work efficiency. Summary of the Invention

[0004] Aiming at the deficiencies of the existing technology, the purpose of the present invention is to provide a drop-type fuse and a casting tool for fuse ceramics to solve the above problems.

[0005] The technical solution of the present invention is realized as follows: A drop-type fuse includes Fuse ceramics, and orifices are provided on both ends and the middle outer wall of the fuse ceramics; Fittings, and the two ends of the fittings are respectively set as a fixed end and a connection end; Notches, which are provided on the side walls at both ends of the fuse ceramics and communicate with the orifices, and the edges of the notches on the side walls of the fuse ceramics are arc-shaped; Wherein, the fixed end of the fitting extends into the orifice and is fixed by cement casting, the connection end extends to the outside of the fuse ceramic through the notch, and the notches at both ends of the fuse ceramic are on the same side.

[0006] By adopting the above technical solution, the notch on the fuse ceramic can cooperate with the convex block on the casting tooling. When installing the fuse ceramic, the edge of the notch abuts against the convex block, thereby positioning the fuse ceramic, making the installation of the fuse ceramic more convenient, making the processing of the fuse ceramic more convenient, and effectively improving the processing efficiency of the drop fuse; the arc-shaped edge has a certain guiding effect, making the placement and positioning of the fuse ceramic smoother and more convenient.

[0007] A casting tooling for a fuse ceramic, comprising A base; A bottom plate, the bottom plate is rotatably connected to the base, the front and rear sides of the bottom plate are respectively provided with a front side plate and a rear side plate, and a spacing adjusting mechanism is connected between the front side plate and the rear side plate; A driving mechanism, the driving mechanism is arranged on the base for driving the bottom plate to rotate on the base; A top plate, the top plate is movably connected above the bottom plate through a lifting mechanism, and the lifting mechanism is used for driving the top plate to move up and down relative to the bottom plate; Wherein, both ends of the fuse ceramic are respectively placed on the front side plate and the rear side plate, and the fuse ceramic is located below the top plate.

[0008] By adopting the above technical solution, the fuse ceramic is placed on the front side plate and the rear side plate, and then the fittings are inserted into both ends and the middle of the fuse ceramic one by one and fixed. First, the fitting in the middle of the fuse ceramic is cast and fixed. After it solidifies, the driving mechanism drives the bottom plate, the front side plate, the rear side plate and the fuse ceramic to rotate, so that one end of the fuse ceramic faces upward and then is cast. After it solidifies, it rotates again, so that the other end of the fuse ceramic faces upward and then is cast. After it solidifies, the fuse ceramic is rotated to the initial state, and then the fixation of the fittings at both ends of the fuse ceramic is released. The lifting mechanism drives the top plate to rise. Since the fitting in the middle of the fuse ceramic remains fixed, the fuse ceramic will rise with the top plate, thereby disengaging from the front side plate and the rear side plate. Then the worker holds the fuse ceramic and releases the fixation of the fitting in the middle of the fuse ceramic, and the fuse ceramic can be taken out. The operation is very convenient and there is no need to disassemble and assemble the top plate.

[0009] The present invention is further configured as: the lifting mechanism includes: A lifting cylinder, the lifting cylinder is installed on the bottom plate; A connecting column, the upper end of the connecting column is fixedly connected to the top plate; A guide rod, the guide rod is arranged at the lower end of the connecting column and passes downward through the bottom plate and is slidably connected to the bottom plate; Wherein, the telescopic shaft of the lifting cylinder passes upward through the bottom plate and is connected to the lower end of the connecting column, and at least two groups of the lifting mechanisms are respectively located at the left and right ends of the top plate.

[0010] By adopting the above technical solution, the lifting cylinder drives the top plate and the connecting column to rise or fall through the telescopic shaft, and the guide rod can effectively improve the stability of the top plate and the connecting column during lifting and lowering.

[0012] By adopting the above technical solution, the convex block can limit the two ends of the fuse ceramic, thereby preventing the fuse ceramic from moving axially when placed on the front side plate and the rear side plate. The arc-shaped groove can prevent the fuse ceramic from moving laterally, thus effectively improving the stability of the fuse ceramic when placed on the front side plate and the rear side plate; when installing the fitting into the fuse ceramic, one end of the fitting is correspondingly clamped into the limit groove, so that when the other end of the fitting is inserted into the orifice, it is in the center position, and the positioning is more accurate, effectively improving the connection accuracy and stability between the fitting and the fuse ceramic, and improving the consistency of the product quality; after the fitting is clamped into the limit groove and inserted into the orifices at both ends and the middle of the fuse ceramic one by one, it is fixed by the clamp, which can prevent the fitting from moving during pouring and when the cement solidifies, resulting in the deviation of the position of the other end of the fitting from the orifice of the fuse ceramic. The present invention is further configured as: further comprising: Ultrasonic vibrator, the ultrasonic vibrator includes an ultrasonic generator and an ultrasonic vibration head; First through hole, the first through hole is opened at the bottom of the limit groove and penetrates through the front side plate, the rear side plate and the top plate; Wherein, the number of the ultrasonic vibrators, the first through holes and the limit grooves is the same. The ultrasonic generator is fixedly installed on the back surfaces of the front side plate, the rear side plate and the top plate and matches the limit groove. The ultrasonic vibration head passes through the first through hole and extends into the limit groove. When the fitting is installed in the limit groove, the ultrasonic vibration head contacts the fitting, and the outer diameter of the ultrasonic vibration head is smaller than the inner diameter of the first through hole.

[0013] By adopting the above technical solution, when pouring the orifice of the fuse ceramic, by starting the ultrasonic vibrator, the vibration generated by the ultrasonic vibration head is directly transmitted to the cement in the orifice through the fitting, thereby discharging the air bubbles in the cement, making the cement more compact and having a better fixing effect on the fitting. The vibration generated by the ultrasonic vibration head directly acts on the cement through the fitting, and the fitting has a better effect of transmitting vibration, which can effectively prevent the vibration wave from being transmitted to the outer shell of the fuse ceramic after the ultrasonic vibration head contacts the front side plate, the rear side plate or the top plate, thereby causing vibration attenuation and effectively ensuring the ultrasonic vibration effect.
