Abstract
The utility model discloses a special stand of an arrester for preventing bird trouble. The special stand of an arrester for preventing bird trouble is characterized in comprising a clip hook and a stand, wherein the clip hook and the stand are connected by screw thread, and the stand is provided with a plurality of arc-shaped umbrella skirts. The utility model has the advantages that the special stand has good electric property and mechanical property, high distortion temperature and good moisture resistivity and fungus resistance and is suitable to use outdoors. The material is light, flexural strength is more than or equal to 300MPa, tensile strength is more than or equal to 300MPa, and impact strength is more than or equal to 15 KJ/m2; thus, the material has enough strength and can not be broken even if the material falls from the third floor. Because insulating material is adopted to make the special stand of the arrester, the creepage distance of the arrester is not affected, and the arrester reaches the IV-level dirt-resistant level. The installation stand has reasonable structural design and beautiful appearance; because the umbrella skirt capable of strengthening and preventing bird troubles is designed behind the stand, the creepage distance and the dirt-resistant performance are improved.
Description
Technical field
The utility model relates to a kind of anti-bird pest lightning arrester special stand that is applicable to that band release unit lightning arrester, overvoltage protection device install and fix, belong to lightning arrester attachment technique field.
Background technology
In order to satisfy vast electric power system user to the demand that lightning arrester does not have a power failure, non-maintaining, fault point is sought easily, band release unit lightning arrester has appearred.But have unreliability on surge arrester support, subject matter shows the following aspects:
Handle the stainless steel material of use have with common steel plate through hot galvanizing, there is certain problem in the installing rack of above electric conducting material, because the employing electric conducting material is done installing rack through the use in 1 year.If lightning arrester suffers direct lightning strike, resistor disc punctures, the just direct ground connection of mounting bracket, and the release unit akinesia, lightning arrester also just can't be out of service, do not reach the requirement that does not have a power failure.
Mounting bracket with electric conducting material is made as the release unit action, breaks away from assembly and effectively breaks away from, and forms floating potential, has potential safety hazard.Simultaneously,, reduced the creepage distance of lightning arrester, influenced the insulation property and the dirty grade of resistant of lightning arrester because adopt electric conducting material.
The mounting bracket that adopts some insulating material to do is also arranged on the market, but, rupture and break at installation and the support that occurs repeatedly in service because the selection of material is not right, accidents caused.
The full skirt of mounting bracket is designed to horizontal direction, and birds are cooked nest easily on support, thereby reduces equipment outer insulation.
Summary of the invention
The utility model proposes a kind of anti-bird pest lightning arrester special stand, its purpose is intended to overcome the defective that prior art exists and since in the support rear design play the full skirt of booster action and anti-bird pest, increased the dirty property of creepage distance and resistant.
Technical solution of the present utility model: it is characterized in that comprising clamp and support, wherein clamp and support are by thread connection, and support is provided with several arc full skirts.
Advantage of the present utility model: this special stand has good electric property and mechanical performance, the heat distortion temperature height, and moisture resistivity and fungus resistance are good, are fit to outdoor use.This material is light, bending strength 〉=300MPa, tensile strength 〉=300MPa, impact strength 〉=15KJ/m
2, have enough intensity, down fall from three floors all not bad.And, do not influence the creepage distance of lightning arrester owing to adopt insulating material to make the special stand of lightning arrester, make lightning arrester reach the dirty grade of IV level resistant.This mounting bracket reasonable in design, good looking appearance since in the support rear design play the full skirt of booster action and anti-bird pest, increased the dirty property of creepage distance and resistant.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Accompanying drawing 2 is scheme of installations of the present utility model.
Among the figure 1 is clamp, the 2nd, and support, the 3rd, lightning arrester, the 4th, circuit metal cross arm.
Embodiment
Contrast accompanying drawing 1, its structure comprises clamp 1 and support 2, and wherein clamp 1 and support 2 are thread connection, and design has several arc full skirts on the support 2.
Contrast accompanying drawing 2, its structure connects by clamp 1 and lightning arrester 3 with special expoxy glass steel, by support 2 lightning arrester 3 is installed on the circuit metal cross arm 4.Design has the arc full skirt of several booster actions on the support 2, increases the creepage than distance of lightning arrester 3, and can effectively prevent bird pest.
