Description
[technical field]
The present invention relates to more changing device of a kind of insulator, especially relate to a kind of tangent tower upside-down mounting thread gripping-board insulator more changing device of electricity band point of ploughing.
[background technology]
The filthy a lot of adverse effects that known high-voltage transmission line insulator string is produced in running are embodied in: airborne dust, saline and alkaline, industrial fumes or various particulate or birds droppings all can be deposited in the insulator string outer surface and form pollution layer; Because pollution layer is varied with the difference of environment at the surperficial dunghill of overhead transmission line insulator string, very complicated; But be broadly divided into two kinds of the filthy and industrial filths of naturality; But industry is filthy, and only to appear at industrialization higher relatively and possess the place of certain pollutant sources, that is to say that the naturality filth is general relatively.
Known naturality is the filth that under natural environmental condition, produces to the filth of high-voltage transmission line insulator string; Common mainly contains: dust is filthy: mainly be the dust that wind and vehicle are kicked up from ground, and the composition of dust and the adhesive capacity of insulator surface had bigger influence to the operation of line insulator; And along with the aggravation of air pollution; A large amount of use chemical fertilizer, agricultural chemicals and industrialized development have all increased the content increase of soluble conductive thing in the soil, and these materials are bonded at the decreasing insulating that insulator possibly caused in the insulator string outside: the dust filth generally is not convenient to cleaning by force and at the insulator surface adhesion yet; Birds droppings is filthy: mainly be that birds are dropped on ultra-high-tension power transmission line or insulator string top pylon temporarily, birds droppings has certain floating putting forth effort, and also is not easy to clean; The freezing filth of ice and snow: mainly be the conductive layer that ice and snow forms on insulator string, the electric action that ice and snow can be direct or indirect, electric field distorts, and causes insulator string flashover to occur; Saline and alkaline filth is after grit that wind will have a saline and alkaline composition blows afloat; Saline and alkaline particulate waves with the wind and falls the long-pending line insulation sub-surface that is attached to; Moisture content in the saline and alkaline filthy ability absorbing air has more solvable composition and has strong electrolytes such as sodium, sylvite, and insulation is had the bigger danger side of body; Particularly under mist, dew high humidity, the line insulation level is reduced greatly.
Cross-arm at the flip-over type tangent tower is to adopt two angle steel upside-down mountings to become
type; Suspension insulator upper end on the tangent tower hangs in the jack on angle steel two vertical planes, and the bottom is directly connected on the lead " line conductor just ".
Because two angle steel upside-down mountings become
type; The middle space of reserving is little; And to promote lead when changing insulator string exactly; Dwindle the distance between lead and the cross-arm; The load transfer that insulator string is born is to the instrument of changing, but insulator string charged for replacement device of the prior art can't solve the support problem of upper space; Can only can change insulator string through having a power failure so change operation for insulator string at present.
[summary of the invention]
In order to overcome the deficiency in the background technology; The invention discloses a kind of tangent tower upside-down mounting thread gripping-board insulator more changing device of electricity band point of ploughing; Tangent tower upside-down mounting thread gripping-board insulator of the present invention plough electricity band point more changing device rise through the end line bar and make the pressure transfer of lead; Realized not having a power failure in the operation and avoid the effect of electric field distortion, having overcome needs the drawback that has a power failure in the existing operating type.
For realizing the foregoing invention purpose, the present invention adopts following technical scheme:
A kind of tangent tower upside-down mounting thread gripping-board insulator more changing device of electricity band point of ploughing; Comprise end line bar, connecting rod, support bar, sheave and backguy that two nested structures are identical; The middle part of end line bar is provided with to lower half circle; On the medial surface of lower half circle, be pasted with electro-insulating rubber, the two ends of end line bar are respectively equipped with the connecting hole of up/down perforation; The middle part of said connecting rod is provided with and raises up, and is respectively equipped with the connecting hole of up/down perforation at the two ends of connecting rod; The connecting hole at two terminal wire bar two ends and the connecting hole at two connecting rod two ends are connected to form " mouth " font structure through clamping screw; Middle part at support bar is provided with sheave, and the middle part of said sheave and support bar is slidingly matched; An end that on the convexity of the middle part of two connecting rods, connects two backguys respectively, two backguy middle parts ride over respectively on the sheave race of two support bars, and the other end of two backguys is a crimped end; Wherein end line bar, connecting rod are high-strength nylon; Backguy is a nylon material.
The described tangent tower upside-down mounting thread gripping-board insulator more changing device of electricity band point of ploughing is respectively equipped with spacing card in the bottom, both sides of support bar, the be in line clamping position limiting structure of tower cross-arm middle part neutral gear of said spacing card-shape.
The described tangent tower upside-down mounting thread gripping-board insulator more changing device of electricity band point of ploughing, the crimped end of two backguy other ends is artificial tractive or take-up equipment.
Owing to adopted technique scheme, the present invention to have following beneficial effect:
The tangent tower upside-down mounting thread gripping-board insulator of the present invention more changing device of electricity band point of ploughing tightens up backguy through artificial tractive or take-up equipment, drives the pressure transfer that the end line bar rises and makes lead, just can easily change insulator string then.The present invention has realized not having a power failure in the operation and has avoided the effect of electric field distortion, and having overcome needs the drawback that has a power failure in the existing operating type, thereby realizes the protection whole piece transmission line purpose of safe operation that do not have a power failure.
