Abstract
The utility model relates to a novel grading ring of a lightning arrestor, which comprises a plurality of parallel and coaxial annular parts. Adjacent annular parts are connected through connecting bars peripherally disposed on the annular parts, connecting posts connected with the connecting bars are arranged on the periphery of the each annular part, connecting holes matching with one another are disposed at corresponding positions on the connecting bars and the connecting posts, and metal spring plates are arranged on outer sides of connecting portions of the connecting bars and provided with connecting holes correspondingly. The novel grading ring is in a split structure so that convenience in transport and reduction in damage rate are achieved.
Description
Technical field
The utility model relates to a kind of arrester grading ring, belongs to the electric armour clamp technical field.
Background technology
Arrester grading ring is to prevent sideflash to equipment damage, all presses around the realization equipment, guarantees that object is poor at each position no-voltage of annular, reaches the purpose of all pressing.Raising along with instructions for use, the volume of arrester grading ring has the trend of increase, as also making traditional integral type grading ring version, certainly will cause increasing substantially of cost of transportation, and the increase of volume causes easily also arrester grading ring to be damaged in transportation.
The utility model content
The utility model is at above-mentioned defective, and purpose is to provide a kind of arrester grading ring is made split-type structural, thereby reaches the target of convenient transportation, minimizing damage probability.
The technical solution of the utility model is: the utility model comprises some parallel annular bodies, each annular solid coaxial line, realize connecting by the dowel that circumferentially is arranged on the annular solid between the adjacent ring body, annular solid is circumferentially with the joint pin that is connected with dowel, dowel and joint pin correspondence position are provided with the connecting hole of working in coordination, the connecting portion outside of dowel is provided with elastic sheet metal, and the elastic sheet metal correspondence position is provided with connecting hole.
Described dowel, elastic sheet metal correspondence position vertically are provided with the connecting hole that is on the same straight line.
Described dowel is realized being connected each bending part rounding off of bolt by bolt with joint pin.
The utility model has the advantages that: 1) the utility model is provided with grading ring and dowel split, and the big like this volume that subtracts grading ring has made things convenient for the transportation of arrester grading ring, has reduced its probability of being damaged in transportation; 2) the utility model is established elastic sheet metal in the outside of dowel, like this in dowel and joint pin connection procedure, can guarantee the reliability that both contact, make it to form the integral structure form of essence, the distortion of elastic sheet metal has simultaneously also improved both bonding strengths; 3) the utility model dowel is provided with some connecting holes, can select suitable connecting hole according to the actual installation needs like this, has improved arrester grading ring and has used flexibility; 4) the bending part rounding off of the utility model bolt can effectively prevent the generation of point discharge phenomenon.
Description of drawings
Fig. 1 is a structural representation of the present utility model
1 is that annular solid, 2 is that joint pin, 3 is that connecting hole, 4 dowels, 5 are elastic sheet metal among the figure.
Embodiment
The utility model comprises some parallel annular bodies 1, each annular solid 1 coaxial line, realize connecting by the dowel 4 that circumferentially is arranged on the annular solid 1 between the adjacent ring body 1, annular solid 1 is circumferentially with the joint pin 2 that is connected with dowel 4, dowel 4 and joint pin 2 correspondence positions are provided with the connecting hole 3 of working in coordination, the connecting portion outside of dowel 4 is provided with elastic sheet metal 5, and elastic sheet metal 5 correspondence positions are provided with connecting hole 3; Dowel 4, elastic sheet metal 5 correspondence positions vertically are provided with the connecting hole 3 that is on the same straight line; Dowel 4 is realized being connected each bending part rounding off of bolt by bolt with joint pin 2.
When the utility model uses, now select corresponding connecting hole 3 as required, then dowel 4 is pressed in the joint pin 2, reach both closely purposes of contact, after both positions put in place, realize that by bolt both is fixedly connected by elastic sheet metal 5 distortion.
