Abstract
The utility model relates to a fully hinged combination phase-to-phase spacer, which comprises a four-split wire spacers and a regulating suspension loop. The fully hinged combination phase-to-phase spacer is characterized in that: in the direction from left to right, a phase-to-phase spacer bracket is fixed on the four-split wire spacer, the front end of the phase-to-phase spacer bracket is connected with the left end of a turn buckle through a U-shaped suspension loop, the right end of the turn buckle is connected with a composite insulator through the U-shaped suspension loop, the right end of the composite insulator is connected with the regulating suspension loop through the U-shaped suspension loop, and same components are symmetrically arranged toward the right end by taking the regulating suspension loop as a center. The fully hinged combination phase-to-phase spacer is wide in the regulating length range, enables an installed phase-to-phase spacer to maintain a natural state, and reduces the drawing force and the pressure, thereby achieving good anti-swing effect, preventing occurrence of a wire winging phenomenon effectively, being convenient for construction and operating maintenance, and improving the safety and the reliability of operations of vertically arranged power transmission lines of an iron tower cross arm.
Description
Technical field
[0001] the utility model relates to a kind of transmission line facility, and particularly a kind of full articulation the first and second combination inter-phase spacers are specifically under iron tower of power transmission line cross-arm vertical arrangement, the device that a kind of establishment phase conductor of different alternate installations is waved.
Background technology
[0002] between the nearest more than ten years, China's electric utility is flourish, the domestic electric network composition that has basically formed take the 500kV transmission line as main grid structure.Along with the variation of global climate, in recent years, the probability that conductor galloping, lightning stroke trip, the icing phenomenon of falling the tower occur increases, bring thus the transmission line secondary disaster more common, the safety and reliability of transmission line be can not be guaranteed, and wherein comparatively serious is to wave, and the harm of waving generation is many-sided, flashover, tripping operation occur in the lighter, severe one causes gold utensil and insulator to damage, disconnected strand of wire, broken string, and shaft tower is loosening, break away from, fall tower.Theoretical and the prevention method research of transmission line galloping carry out the history that has recent two decades, and obtained a large amount of achievements in research, produce and the evolution complexity owing to waving, contain simultaneously many enchancement factors, not yet form at present the mechanism explain of generally acknowledging, all kinds of Anti-galloping devices have it, and also there is the limitation of using in design feature while targetedly, of a great variety based on the anti-dance device that the Anti-galloping design philosophy is designed, single commonly used two parallel wielded-proof device that mainly contains, cable clip rotary type conductor spacer etc., its subject matter is that the inter-phase spacer adjusting range is little, installation is very inconvenient, and the inter-phase spacer of these structures can't use in the vertical dual loop transmission line of 500kV.
Summary of the invention
The purpose of this utility model provides a kind of vertical arrangement used for transmission line full articulation the first and second combination inter-phase spacers, has been mainly the different alternate problems that Anti-galloping inter-phase spacer length is difficult to adjust that install additional of transmission line that solve.
The technical scheme that provides of the present utility model is: comprise the conductors on quad bundled conductor spacer, adjust link, it is characterized in that: direction from left to right, at the fixing inter-phase spacer bracket of conductors on quad bundled conductor spacer, the inter-phase spacer bracket front end is connected with the turn buckle left end by U-shaped link, the turn buckle right-hand member is by U-shaped link and compound inslation sub-connection, the right-hand member of composite insulator is connected with the adjustment link by U-shaped link, is symmetrical arranged parts same as described above to right-hand member centered by adjusting link.
The utility model is by reliably connecting between various High Strength Hardware parts, the adjustment length range is large and mode is more, make the inter-phase spacer after the installation keep nature, reduce pulling force and pressure, thereby reach good Anti-galloping effect, the generation of establishment conductor galloping phenomenon, simultaneously convenient construction and operation maintenance, thus improve the security reliability of steel tower cross-arm vertical arrangement transmission line operation.
The utility model has the advantages that:
1,Flexibly spacer bracket is rotated in employing, cooperates U-shaped link to connect, and rotates flexibly, occurs the gold utensil stuck phenomenon when avoiding conductor galloping.
2, be equipped with the adjusting turn buckle, realize electrodeless adjusting, adjustable range significantly increases, and effectively solves the factor such as construction error and causes the phenomenon that the phase spacing deviation is large, inter-phase spacer is difficult to install.
,For further enlarging adjusting range, the length of regulating link in the utility model can suitably increase.
,This kind structure can realize stepless level and smooth adjustment, stops to regulate the blind area in the gold utensil installation in the past.
, efficiently solve inter-phase spacer length and be difficult to control this difficult point, ensured the security reliability of circuit, have simultaneously the characteristics such as simple in structure, reasonable in design, economic and practical, that generalization is strong.
Description of drawings
Accompanying drawing 1 is the utility model full articulation the first and second combination inter-phase spacer assembly drawings, and the utility model structure member is arranged symmetrically with at two ends centered by adjusting link.
Component serial number among the figure: conductors on quad bundled conductor spacer 1, U-shaped link 2, turn buckle 3, composite insulator 4 is adjusted link 5, inter-phase spacer bracket 6.
Embodiment
As shown in Figure 1, concrete structure is as follows: direction from left to right, utilize fixedly inter-phase spacer bracket 6 of iron plate and screw at conductors on quad bundled conductor spacer 1, inter-phase spacer bracket 6 front ends have screw, adopt bolt to be fixedly connected with U-shaped link 2, turn buckle 3 left ends all are connected with U-shaped link 2, turn buckle 3 right-hand members are connected with composite insulator 4 by U-shaped link 2, the right-hand member of composite insulator 4 is connected with adjustment link 5 by U-shaped link 2, two ends are arranged symmetrically with the utility model assembling parts to adjust centered by the link 5 to the left and right, and the remaining part right-to-left is same as described above to adjusting link.
