Abstract

The utility model discloses a fixed type outdoor drop-out fuse, which comprises an installation plate, an insulator and a fuse sleeve, wherein one end of the installation plate is connected with the middle of the insulator; wiring terminals are arranged at two ends of the insulator; a hanging hook clip and a spring clip are respectively arranged at the two ends of the insulator; the two ends of the fuse sleeve are a hanging connection end and a drop-out end respectively; the hanging connection end is in hanging connection with the hanging hook clip of the insulator; and the drop-out end is clamped with the spring clip of the insulator. The fixed type outdoor drop-out fuse is characterized in that a conductive connection plate which is integrated with the insulator is led out of each of the two ends of the insulator; and the ends of each conductive connection plate are respectively connected with the hanging hook clip and the spring clip through bolts. The fixed type outdoor drop-out fuse has the advantages that the conductive connection plates which are integrated with the insulator and led out of the two ends of the insulator are directly connected with the clips, the connection structure is simplified, the fuse is convenient to install, exposure of a conductive body is reduced, and the insulating performance of the insulator is improved.

Description

Fixed outdoor drop-out fuse

Technical field

The utility model relates to a kind of fixed outdoor drop-out fuse, is mainly used in the overload protection of transmission line.

Background technology

Existing drop out fuse primary structure comprises insulator, dop and fuse tube, and the two ends of insulator are fixedly connected with an end of connecting plate through bolt, and the other end of this connecting plate is connected with dop through bolt again, and the two ends of fuse tube are connected in two dops.The shortcoming that exists is: the two ends of insulator are connected complex structure through bolt with connecting plate with dop; Trouble is installed; It is many that electric conductor (comprising bolt and nut etc.) exposes, easily corrosion and influence the insulation property of insulator.

Summary of the invention

The purpose of the utility model provides a kind of fixed outdoor drop-out fuse, with dop is connected complex structure through bolt with connecting plate with the two ends that solve the insulator that prior art exists; Trouble is installed; It is many that electric conductor exposes, easily corrosion and influence the problem of the insulation property of insulator.

The technical scheme of the utility model is: a kind of fixed outdoor drop-out fuse, comprise mounting panel, insulator and fuse sleeve pipe, and an end of mounting panel is connected with the middle part of insulator, at the two ends of insulator binding post is housed; Hook dop and spring chuck also are housed respectively at the two ends of this insulator; The two ends of fuse sleeve pipe are respectively articulated end and fall end, and the hook dop of this articulated end and insulator articulates; This falls the spring chuck clamping of end and insulator; It is characterized in that; Draw a conductive connection plates with this insulator one at the two ends of described insulator respectively, respectively be connected with spring chuck with described hook dop respectively through bolt in the end of this conductive connection plates.

Described insulator comprises insulating rod, sealing shroud and anti-water pond, is coated with the sealing shroud of waterproof insulation in the outside of insulating rod, is provided with a plurality of anti-water ponds spaced apart vertically in the outside of sealing shroud, and this anti-water pond and sealing shroud are structure as a whole.

Middle part and two ends difference socket one metallic sheath at described insulating rod; The metallic sheath at middle part and the welding of the lower end of described mounting panel; The bottom that is coated on this mounting panel, the top and the metallic sheath outside of conductive connection plates are extended in the metallic sheath at two ends and the welding of the upper end of described conductive connection plates, described sealing shroud.

The conductive connection plates that is connected with said hook dop is a L shaped plate, and another described conductive connection plates is straight plate.

The beneficial effect of the utility model is: the conductive connection plates of drawing one from the two ends of insulator directly is connected with dop, has simplified syndeton; Easy for installation; Reduce the exposure of electric conductor, improved the insulation property of insulator.
