Abstract

A rod-shaped composite porcelain insulator is composed of the components of a T-shaped fitting, sealing sleeves 2, a porcelain insulator 3, a core rod 4, a towel head fitting 5, etc. The T-shaped fitting 1 and the bowl head fitting 5 are respectively arranged at two ends of the core rod 4 in a pressing manner. The porcelain insulator 3 sleeves the core rod 4. A plurality of umbrella skirts are arranged on the porcelain insulator 3. The porcelain insulator 3 sleeves the core rod 4. Two ends of the porcelain insulator are sealed by the sealing sleeves 2 for preventing water and moisture from entering. A middle clearance between the porcelain insulator 3 and the core rod 4 is filled with insulating glue. The fittings at two sides of the insulator have many forms, thereby adapting with assembling of different wire clamps. On the condition that the insulator breaks because of a lightning stroke, the inner core rod does not break, and therefore falling from a high position is prevented. According to the structure in which the insulated core rod and the porcelain insulator sleeve are combined, advantages of the composite insulator and the porcelain insulator are kept, and defects of the composite insulator and the porcelain insulator are prevented.

Description

Rod is combined porcelain insulator

Technical field：

The present invention relates to electrical power distribution line security runs field, the porcelain overcoat rod being connected with strain clamp is exhausted Edge.

Background technology：

Generally rod type insulator mainly has compound rod type insulator and porcelain rod type insulator.Composite rod insulator Overcoat full skirt use silastic material, inner core adopt high-strength insulating plug, the compound inslation of high-quality The advantage of son is lightweight, resistance to mechanical intensity is big, hydrophobicity is good, but uvioresistant aging resistance is poor, short life, Full skirt is easily pipped by flying bird thus affecting Insulators Used, silastic material high cost simultaneously, and illegal producer is Reduces cost is easily faked；Porcelain insulator uvioresistant aging resistance is fabulous, the life-span is extremely grown, will not be pecked by birds Broken, because soil low cost is not required to fake, but heavy frangible, when being struck by lightning, easily explosion goes offline, and causes circuit Fault outage, can cause pedestrian's electric shock when serious.The present invention adopts high-strength insulating plug as carrier, core Excellent overcoat porcelain insulator full skirt, even if after porcelain insulator full skirt is subject to thunderbolt part fragmentation, because internal core rod will not Fracture, circuit will not be from falling from high altitude.Therefore solve the problems of composite insulator composite sheath, simultaneously Solve the disconnection that easily bursts after porcelain insulator is struck by lightning, significantly reduce porcelain insulator heaviness problem simultaneously, Its cost is planted between product between the first two.

Content of the invention：

This device is a kind of electrical power distribution circuit comparatively ideal porcelain overcoat rod insulator.

The technical scheme is that：

A kind of power distribution circuit rod is combined porcelain insulator, by fourth head gold utensil 1, sealing shroud 2, porcelain insulating Son 3, plug 4, bowl head gold utensil 5 etc. are constituted, and fourth head gold utensil 1 and bowl head gold utensil 5 are crimped on core respectively The two ends of rod 4, porcelain insulator 3 is enclosed within plug 4；Several full skirts are had on porcelain insulator 3, porcelain is exhausted Edge 3 is enclosed within plug 4, and two ends sealing shroud 2 seals, and prevents infiltration from making moist, porcelain insulator 3 with The intermediate gaps insulating cement of plug 4 tamps.

Brief description：

Fig. 1 is rod composite ceramic insulator structure figure.

Fig. 2 is that rod is combined porcelain insulator collection lightning protection, the structure chart of grounding function one.

Embodiment

This rod is combined porcelain insulator, by fourth head gold utensil 1, sealing shroud 2, porcelain insulator 3, plug 4, bowl Head gold utensil 5 grade composition, fourth head gold utensil 1 and bowl head gold utensil 5 are crimped on the two ends of plug 4, porcelain insulating respectively Son 3 is enclosed within plug 4.Several full skirts are had on porcelain insulator 3, porcelain insulator 3 is enclosed within plug 4, Two ends sealing shroud 2 sealing prevents infiltration from making moist, the intermediate gaps insulating cement of porcelain insulator 3 and plug 4 Tamp.The both sides gold utensil of insulator has various ways, to adapt to the assembling of different wire clamps.

When even if insulator is subject to thunderbolt fragmentation, internal core rod will not rupture, therefore circuit will not be from falling from high altitude. The structure that insulation mandrel is combined with porcelain insulator overcoat, the advantage remaining composite insulator and porcelain insulator, Overcome its shortcoming again.
