Abstract
The utility model discloses a kind of steel tower and change double hanging point equipment, it comprises two T-shaped link plates and two U-shaped links, two described T-shaped link plates be articulated in symmetrically on cross-arm and the lower end of each described T-shaped link plate respectively from top to bottom through cross-arm hollow parts and to downward-extension, two described U-shaped links hold in the palm symmetrically bottom insulator duplex plate and the upper end of each described U-shaped link is affixed with the lower end bolt of corresponding T-shaped link plate respectively, described insulator duplex plate bottom can hold up wire by symmetrically arranged two insulators, this insulator duplex plate upper center also by an insulator list hanging point and cross-arm affixed.The utility model changes single hanging-point insulator string equipment for being with TURP, by installing T-shaped link plate and U-shaped link additional, effectively enhances the security and stability of single hanging-point insulator string.
Description
Technical field
The utility model relates to a kind of power transmission and transforming equipment, and especially a kind of steel tower changes double hanging point equipment.
Background technology
According in " Tianjin Power Company power transmission and transforming equipment technological transformation principle ", " 3.1.6.5 line crossing residential block, factories and miness, villages and small towns, railway, navigable river, 110kV and above power circuit, highway, a Class II highway, crossing pole insulator string should adopt double hanging point, two insulator string string." this clause is intended to ensure that insulator ruptures, the situation such as landing, wire does not drop down onto on the object being spanneds such as residential block, railway, highway, so as not to cause casualties, damage to property.
But along with the continuous lifting of urban construction, after many scissors crossings appear at steel tower foundation, often there is the phenomenon not meeting safety requirements, how to reduce cost and can improve again the fail safe of handing over across section, transmission of electricity specialty proposes the research and development proposal single hanging point being changed into double hanging point, develops simple and reliable equipment.
Summary of the invention
The technical problems to be solved in the utility model is to provide that a kind of stability is strong and fail safe is high steel tower changes double hanging point equipment.
In order to solve the problems of the technologies described above, the utility model comprises two T-shaped link plates and two U-shaped links, two described T-shaped link plates be articulated in symmetrically on cross-arm and the lower end of each described T-shaped link plate respectively from top to bottom through cross-arm hollow parts and to downward-extension, two described U-shaped links hold in the palm symmetrically bottom insulator duplex plate and the upper end of each described U-shaped link is affixed with the lower end bolt of corresponding T-shaped link plate respectively, described insulator duplex plate bottom can hold up wire by symmetrically arranged two insulators, this insulator duplex plate upper center also by an insulator list hanging point and cross-arm affixed.
The beneficial effects of the utility model are: the utility model changes single hanging-point insulator string equipment for being with TURP, by installing T-shaped link plate and U-shaped link additional, effectively enhances the security and stability of single hanging-point insulator string.
Accompanying drawing explanation
Fig. 1 is the scheme of installation that the utility model steel tower changes double hanging point equipment;
Fig. 2 is the front view that the utility model steel tower changes T-shaped link plate in double hanging point equipment;
Fig. 3 is the end view that the utility model steel tower changes U-shaped link in double hanging point equipment.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
See Fig. 1 to Fig. 3, steel tower of the present utility model changes double hanging point equipment and comprises two T-shaped link plates 7 and two U-shaped links 6, two described T-shaped link plates 7 be articulated in symmetrically on the cross-arm 1 affixed with the steel tower 8 and lower end of each described T-shaped link plate 7 respectively from top to bottom through cross-arm 1 hollow parts and to downward-extension, two described U-shaped links 6 hold in the palm symmetrically bottom insulator duplex plate 5 and the upper end of each described U-shaped link 6 is affixed with the lower end bolt of corresponding T-shaped link plate 7 respectively, described insulator duplex plate 5 bottom can hold up wire 3 by symmetrically arranged two insulators 4, this insulator duplex plate 5 upper center is also affixed with cross-arm 1 by an insulator list hanging point 2.
The utility model changes single hanging-point insulator string equipment for being with TURP, by installing T-shaped link plate 7 and U-shaped link 6 additional, effectively enhances the security and stability of single hanging-point insulator string.
In sum, content of the present utility model is not limited in the above-described embodiment, and those skilled in the art can propose other embodiment within technological guidance's thought of the present utility model, but these embodiments are all included within scope of the present utility model.
