Description

Technical Field

[0001] The invention relates to the technical field of power grid safety, and in particular to a device for a fuse drop-out hanging grounding wire. Background Art

[0002] There is no reliable installation location for the grounding wire of the old 10kV drop-out fuse. When the grounding wire is installed on the lower pole of the drop-out fuse, it is easy to cause poor contact of the grounding wire. When the upper pole of the drop-out fuse is energized, when performing substation transformer or cable operations, it is impossible to ensure a safe distance of 0.7m when installing the grounding wire on the lower pole of the drop-out fuse. Therefore, it is necessary to develop a device for hanging the grounding wire on the drop-out fuse, which can insulate and shield the upper pole of the drop-out fuse while maintaining good contact with the lower pole of the drop-out fuse, providing a stable and reliable hanging point for the grounding wire. Summary of the invention

[0003] The technical solution of the present invention to solve the above technical problems is to provide a device for a drop-type hanging grounding wire of a fuse, comprising: an upper pile head insulating cover, upper and lower connecting structures, an insulating support structure, a lower pile head grounding ring and a spring structure, wherein the upper pile head insulating cover is used to shield the upper pile head of the fuse from three directions; one end of the upper and lower connecting structures is fixed to the upper pile head edge cover, the insulating support structure is fixed to the upper and lower connecting structures, and is used to connect the magnetic column of the fuse; the lower pile head grounding ring is fixed to the other end of the upper and lower connecting structures; the spring structure is fixed to the upper and lower connecting structures, and is used to connect to the lower head groove of the fuse.

[0004] Furthermore, the upper and lower connecting structures are made of insulating resin material.

[0005] The technical solution of the present invention has a simple structure, is easy to install and disassemble, and has a low cost; it can reduce the scope of power outages while ensuring reliable grounding of maintenance cables and transformers. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] The following will be combined with the drawings in the accompanying drawings of the present invention specification to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0011] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0012] In addition, in the present invention, descriptions such as "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "several" or "multiple" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0013] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0014] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.
