Description
Technical field
The utility model relates to electroceramics field, specifically provides a kind of lightning protection porcelain insulator.
Background technology
Anti-thunder insulator adopts and first blocks the design concept of dredging afterwards, for the insulating supporting in overhead transmission line.When lightning overvoltage exceedes insulation blocking certain numerical value, between the starting rod and lower metal leg of lightning protection pillar, cause flashover to discharge, form short-channel, avoid burn through guardwire.
The anti-thunder insulator of prior art comprises following a few class: lightning protection strut composite insulator; Two starting rod, two discharging gap apparatus anti-thunder insulator are set.
Although composite insulator has good anti-filthy level, but composite has the easily aging defect with deteriorating, composite insulator umbrella diameter is less simultaneously, and dry arcing distance is less than porcelain insulator, that is lightning withstand level is less than the lightning withstand level of the porcelain insulator of same length.Two starting rod, two discharging gap apparatus anti-thunder insulator are set, owing to too pursuing effective electric discharge, cause the problems such as input cost is too high, moulding is complicated, installation is difficult.
Summary of the invention
The utility model is for above-mentioned the deficiencies in the prior art, provides a kind of reasonable in design, lightning protection porcelain insulator that tolerance is strong.
The utility model solves the technical scheme that its technical problem adopts: a kind of lightning protection porcelain insulator, comprise insulating part, clamp gold utensil, upper metal cap, starting rod and lower metal leg, be characterized in that described insulating part is pillar ceramic insulator, upper metal cap and lower metal leg difference mucilage binding are in the upper and lower two ends of pillar ceramic insulator, clamp gold utensil is arranged on upper metal cap top by nut, starting rod upper end is fixedly connected with upper metal cap, and lower end and lower metal leg form discharging gap.
In order to adapt to the thunderbolt situation of different regions, can have adjustment bolt hole in starting rod lower end, adjustment bolt hole place is provided with adjustment bolt.
Starting rod upper end is preferably threaded with upper metal cap, both suitably can adjust discharging gap, again convenient fractionation, packaging.
As preferably, clamp gold utensil bottom surface and upper metal cap end face are relatively set with puncture ratchet.
Compared to the prior art lightning protection porcelain insulator of the present utility model, has following outstanding beneficial effect:
(1) profile of insulator porcelain piece part uses pole structure design, and on the one hand, this structure belongs to puncture-proof, makes in circuit use procedure more safe and reliable; On the other hand, the insulator adopting electroporcelain material to make overcomes the composite material easily aging defect with deteriorating, intensity stabilization, and reliability is strong;
(2) starting rod top is connected with upper metallic steel cap thread, and its lower end is provided with adjustment bolt, on the one hand, be easy to split, packaged convenience, on the other hand, can turn starting rod and/or adjustment bolt, suitable adjustment discharging gap, to adapt to different local degree of being struck by lightning at thundery sky and the frequency;
(3) be provided with puncture ratchet, without the need to divesting wire insulation during installation, avoid core to intake and corrosion, installation is very convenient;
(4) tolerance is good, can tolerate burning of about 5 times power frequency heavy-current electric arcs.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of the utility model lightning protection porcelain insulator.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, but not as to restriction of the present utility model.
In the utility model, when not doing contrary explanation, the noun of locality such as " upper and lower, left and right " of use typically refers to reference to upper and lower, left and right shown in the drawings; " inside and outside " refers to profile inside and outside relative to each parts itself.
Provide a most preferred embodiment below:
A kind of lightning protection porcelain insulator, is formed primarily of pillar ceramic insulator 1, clamp gold utensil 2, upper metal cap 3, starting rod 4, lower metal leg 5 and adjustment bolt 6.
Upper metal cap 3 and lower metal leg 5 are respectively by the up and down two ends of mucilage binding cement 7 mucilage binding in pillar ceramic insulator 1.
Clamp gold utensil 2 is fixed on upper metal cap 3 top by bolt and nut 8, and clamp gold utensil 2 bottom surface is relative with upper metal cap 3 end face is fixed with the ratchet 9 that punctures.
Starting rod 4 upper end and upper metal cap 3 are threaded connection.Starting rod 4 lower end has adjustment bolt hole, and adjustment bolt 6 is threaded with starting rod 4 lower end, makes to form discharging gap between adjustment bolt 6 and lower metal leg 5.
The installation method of lightning protection porcelain insulator of the present utility model is identical with the installation method of existing composite insulator, the degree can be struck by lightning according to local thundery sky after installation and the frequency, rotates starting rod 4 and/or adjustment bolt 6, obtains best discharging gap to adjust.
Above-described embodiment, the just one of the utility model more preferably embodiment, the usual change that those skilled in the art carries out within the scope of technical solutions of the utility model and replacing all should be included in protection range of the present utility model.
Claims (4)
