Abstract
A binding-free post composite insulator for a line pressing plate is used on a power station or a power transmission line for supporting a wire and avoiding short circuit caused by the fact that the distance between two phases of wires is reduced to be below a necessary distance due to wire waving caused by ice, wind and the like. This novel insulator changes traditional ligature formula installation wire, and the wire compresses tightly on the ring flange of last flange by the line ball board, again by the bolt with line ball board and ring flange crimping together, and the installation is fixed the wire and is very convenient, has reduced intensity of labour widely, has improved work efficiency, and the installation is firm, guarantees the operation safe distance between double-phase conductor, has improved the reliability of circuit operation.
Description
Technical Field
The utility model relates to a medium voltage electric wire netting insulator, especially a pillar composite insulator. The insulator is used for supporting the wires, is used in places such as transformer substations, railways or power transmission lines and the like, plays a role in insulating and supporting, and avoids short circuit caused by the fact that the wires are shaken due to ice, wind and the like to reduce the distance between two phase conductors to be below a necessary distance.
Background
In recent years, with the continuous acceleration of upgrading and transformation of urban power grids, the construction and transformation of medium-voltage power lines are rapidly advanced. The conventional manner of supporting the wires by the post insulator is shown in fig. 3, and the wires are fixed by binding the wires with a metal tool. Because the problems of manual operation technology and manipulation are mainly solved, the defects of uneven binding, insecurity, labor and time consumption, low working efficiency and the like exist, and the safe operation of the medium-voltage power grid is threatened. Therefore, a new lead fixing mode is provided, and potential safety hazards after the medium-voltage power grid is put into operation can be solved.
Disclosure of Invention
The utility model discloses made the improvement on the basis of current insulator structure, its aim at improves the performance of insulator, guarantees transmission line's safe operation.
The utility model discloses above-mentioned purpose of insulator is realized through following technical scheme:
a binding-free pillar composite insulator with a line pressing plate is structurally characterized by mainly comprising a core rod, an umbrella skirt, an upper flange and a lower flange; the umbrella skirt is fixedly sleeved on the core rod, and the upper flange and the lower flange are respectively installed at the head end and the tail end of the core rod and are fixed with the core rod into a whole; the top end of the upper flange is provided with a lead which is pressed on the flange plate of the upper flange by a line pressing plate.
The wire is formed by pressing the wire pressing plate and a flange plate of the flange together through bolts at two ends of the wire pressing plate.
The wire pressing plate is an omega-shaped plate with an arc ring in the middle, and the lead is positioned in the arc ring of the wire pressing plate.
Compared with the prior art, the beneficial effects of the utility model are that: the top design of the insulator is improved, the lead fixing mode is changed, and the production process is simple and feasible. The two wire fixation approaches are compared as follows:
the traditional binding mode is complex, is easily influenced by human factors, has the phenomena of looseness, unreliability and the like, and influences the safe operation of the line. The novel lead fixing mode is flexible, the operation is convenient, the direction of the fixed lead is flexible, and the lead is more firmly and safely contacted with the fixed hardware fitting, so that the operation is reliable and safe.

Fig. 1 is a schematic structural diagram of the insulator of the present invention.
Fig. 2 is a schematic view of a crimping manner of a wire and an upper flange.
Fig. 3 is a schematic view of a conventional binding manner of a wire and an insulator.
In the figure: the core rod comprises a core rod 1, an umbrella skirt 2, an upper flange 3, a lower flange 4, a wire pressing plate 5, a lead 6 and a bolt 7.
Detailed Description
The following detailed description of the specific embodiments of the insulator structure of the present invention is provided with the accompanying drawings:
referring to fig. 1, the utility model relates to a binding type pillar composite insulator is exempted from to line ball board of taking, its structure mainly comprises plug 1, full skirt 2, upper flange 3, lower flange 4. The core rod 1 is an epoxy glass fiber reinforced plastic core rod, the umbrella skirt 2 is fixedly sleeved on the core rod 1, and the upper flange 3 and the lower flange 4 are respectively installed at the head end and the tail end of the core rod 1 and are fixed with the core rod 1 into a whole. The structure is the same as that of the existing insulator. Referring again to fig. 2, the improvement of the present invention lies in: the lead 6 arranged at the top end of the upper flange 3 is pressed on the flange of the upper flange 3 by the line pressing plate 5, and then the line pressing plate 5 and the flange of the flange 3 are pressed together by bolts 7 at the two ends of the line pressing plate 5. In order to fasten the lead 6 on the flange 3, the line pressing plate 5 is an omega-shaped plate with a circular arc ring in the middle, the lead 6 is positioned in the circular arc ring of the line pressing plate 5, and the lead is firmly pressed on the flange plate without moving by screwing the bolt 7. Compared with the traditional wire and insulator binding mode shown in fig. 3, the defects of the traditional binding mode can be clearly seen: is not only troublesome but also not firm.
The utility model discloses an embodiment: and coating a silicon rubber sheath outside the epoxy glass fiber reinforced plastic core rod 1, sleeving the umbrella skirt 2 after curing, and then crimping the upper flange 3 and the lower flange 4. And then the lead 6 and the wire pressing plate 5 are connected into a whole through a bolt 7. The tightening length of the bolt 7 is adjusted to meet the requirements of different diameter specifications of the lead 6. The supporting wire 6 is very convenient to install, and the direction of the supporting wire can be adjusted by changing the direction of the tension plate 5. Through various tests, the novel insulator is proved to completely meet the requirements of design standards on mechanical property and electrical property, has a simple structure and feasible process, and completely meets the requirements of the power market.
