Abstract
A porcelain-cleat-type low-voltage cable insulator is composed of an upper porcelain cleat, a middle porcelain cleat, a lower porcelain cleat, a fastening bolt and a fixing support. Two parallel semicircular grooves are processed at proper positions on one side of the upper porcelain cleat, two parallel semicircular grooves are symmetrically processed at proper positions on two sides of the middle porcelain cleat respectively, structure of the lower porcelain cleat is completely identical with that of the upper porcelain cleat, and a center penetrating hole in proper size is formed in the middle of each of the three porcelain cleats. When low-voltage cables are mounted, four low-voltage cables are clamped in cleat grooves respectively, and the fastening bolt is tightened to form a whole to be fixed on the fixing support.
Description
Art
The present invention relates to distribution line installing area and particularly relate to a kind of cleat insulator formula low-voltage cable insulator.
Background technology
At present, power distribution station low-pressure line-outgoing adopts by low-voltage cable by after control cubicle, then the mode of low-voltage cable upper boom to client radiation powered.Owing to installing low-voltage cable without special fixture, often make the installation quality of river low-voltage cable and to be attractive in appearancely affected, the more important thing is the thermal diffusivity effect that have impact on low-voltage cable, when high-temperature high-load, electric cable heating is hot, accelerate cable phase insulation aging, after running time is longer, very easily cause short circuit accident, and after accident occurs, cable outer layer insulation outward appearance is without apparent damage, can not directly search, searching by instrument needs one section of one section of dismounting to search, and waste time and energy, and troubleshooting interruption duration is longer.
Summary of the invention
In order to overcome, the deficiency of low-voltage cable without special fixture is installed, the invention provides a kind of cleat insulator formula low tension insulator, as adopted this kind of cleat insulator formula low tension insulator, not only make the cable arrangements neat appearance of installation, also can improve electric cable heating situation, thus reduce cable fault rate, and easy construction is easy.
The technical solution adopted for the present invention to solve the technical problems is: a kind of cleat insulator formula low tension insulator be by three porcelain cleats and
Fastening bolt, a fixed support are formed.Three porcelain cleats are upper porcelain cleat, middle porcelain cleat and lower porcelain cleat respectively, two parallel semi-circular recesses are processed in the appropriate location of upper porcelain cleat side, in the appropriate location, both sides of middle porcelain cleat, the semi-circular recesses that symmetrical machining two is parallel respectively, structure and the upper porcelain cleat of lower porcelain cleat are just the same, have in the middle of three porcelain cleats
The center hole of an appropriate size.
When low-voltage cable is installed, pass from the center hole of upper porcelain cleat, middle porcelain cleat and lower porcelain cleat with fastening bolt, respectively four low-voltage cable A, B, C, N phases are snapped in clamping plate groove, make low-voltage cable become square to arrange, tighten fastening bolt, form an entirety and be fixed on support.
The invention has the beneficial effects as follows, adopt this kind of cleat insulator formula low tension insulator, low-voltage cable marshalling can be made attractive in appearance, improve electric cable heating situation, thus reduce cable fault rate.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is further described.
Fig. 1 is a kind of cleat insulator formula low tension insulator structural representation.
In Fig. 1,1. go up porcelain cleat, 2. middle porcelain cleat, 3. descends porcelain cleat, 4. fastening bolt, 5. fixed support, 6. semi-circular recesses, 7. center hole.
Embodiment
The present invention is made up of three porcelain cleats (1), (2), (3) and fastening bolt (4), a fixed support (5).Three porcelain cleats are upper porcelain cleat (1), middle porcelain cleat (2) and lower porcelain cleat (3) respectively, two parallel semi-circular recesses (6) are processed in the appropriate location of upper porcelain cleat (1) side, in the appropriate location, both sides of middle porcelain cleat (2), the semi-circular recesses (6) that symmetrical machining two is parallel respectively, structure and the upper porcelain cleat (1) of lower porcelain cleat (3) are just the same, have the center hole (7) of an appropriate size in the middle of three porcelain cleats.
When low-voltage cable is installed, pass from the center hole (7) of upper porcelain cleat (1), middle porcelain cleat (2) and lower porcelain cleat (3) with fastening bolt (4), respectively four low-voltage cable A, B, C, N phases are snapped in clamping plate groove (6), low-voltage cable is made to become square to arrange, tighten fastening bolt (4), form an entirety and be fixed on support (5).
Claims (3)
1. a cleat insulator formula low-voltage cable insulator, is made up of three porcelain cleats and fastening bolt, a fixed support, it is characterized in that, upper porcelain cleat, middle porcelain cleat and lower porcelain cleat are stacked configuration, becomes an entirety by fastening bolt and fixed support.
2. a kind of cleat insulator formula low-voltage cable insulator according to claims 1, two parallel semi-circular recesses are processed in the appropriate location of upper porcelain cleat side, in the appropriate location, both sides of middle porcelain cleat, the semi-circular recesses that symmetrical machining two is parallel respectively, structure and the upper porcelain cleat of lower porcelain cleat are just the same.
3. a kind of cleat insulator formula low-voltage cable insulator according to claims 1, has the center hole of an appropriate size in the middle of three porcelain cleats.
