Description

Insulating sheath mounting

Technical Field

The utility model relates to an insulating fixing device field, more specifically relates to an insulating sheath mounting.

Background

At present, a 10kV bus of a transformer substation generally adopts a hard wire of a tubular bus or a rectangular bus, and a thermoplastic insulating sheath is used for wrapping the bus in order to prevent a short circuit of the transformer in a near area. The bus is generally cut into a section of six meters at the longest to be transported to a transformer substation in a segmented mode and then installed, and in the installation process, connection between the bus and the bus, connection between the bus and other equipment such as a wall bushing and flexible connection needing to be additionally installed between the buses when a bus bridge is too long need to be connected with an insulating sheath to guarantee the insulating performance of the bus. The field is additionally provided with the insulating sheath, fixing parts need to be used, and the fixing parts such as buttons and bands made of plastic or rubber materials are generally adopted to fix the insulating sheath in the field work at present. The fixing piece is exposed to the sun, damp and heated for a long time outdoors, and is easy to age and break, so that the insulating sheath falls off, and the insulating protection effect is lost. In addition, the fasteners such as buttons and bands made of the current plastic or rubber materials cannot be used for the second time after being detached.

SUMMERY OF THE UTILITY MODEL

The utility model discloses an overcome above-mentioned prior art in the easy ageing fracture of mounting of insulating cover and lose the fixed action defect, provide an insulating sheath mounting.

In order to solve the technical problem, the technical scheme of the utility model as follows:

an insulating sheath mounting, comprising: the metal wire is tightly attached to the center of the insulating material layer, and the insulating material layer is of a cylindrical structure.

The utility model discloses a at insulating material layer built-in metal wire, strengthened the toughness of mounting, overcome the easy ageing cracked defect of traditional mounting, strengthened insulating sheath's insulating effect.

In the scheme, the metal wire is a single-strand or multi-strand strong-toughness metal wire. According to the actual demand, a single-stranded metal wire or a multi-stranded metal wire is adopted to meet different fixing strengths.

In this embodiment, when the metal wire is a plurality of strands, the plurality of strands are twisted with each other. The twisting of the multi-strand wires to each other further enhances the toughness.

In this scheme, the insulating material layer is a pyrocondensation insulating material layer. The thermal shrinkage insulating material layer is insulating, anticorrosive and wear-resistant.

In the scheme, the insulating material layer is a 10kV heat-shrinkable insulating material layer.

In the scheme, the length and the diameter of the fixing piece are adaptive to the hole position to be fixed.

In the scheme, the diameter of the metal wire is 2mm-5 mm.

Compared with the prior art, the utility model discloses technical scheme's beneficial effect is:

Detailed Description

The drawings are for illustrative purposes only and are not to be construed as limiting the patent;

for the purpose of better illustrating the embodiments, certain features of the drawings may be omitted, enlarged or reduced, and do not represent the size of an actual product;

it will be understood by those skilled in the art that certain well-known structures in the drawings and descriptions thereof may be omitted.

The technical solution of the present invention will be further explained with reference to the accompanying drawings and examples.

Example 1

Fig. 1 is a schematic front sectional view of the present invention, and fig. 2 is a schematic cross-sectional view of the present invention. An insulating sheath mounting, comprising: the metal wire 1 is tightly attached to the center of the insulating material layer 2, and the insulating material layer 2 is of a cylindrical structure.

The utility model discloses a at insulating material layer 2 built-in metal wire 1, strengthened the toughness of mounting, overcome the easy ageing cracked defect of traditional mounting, strengthened insulating sheath's insulating effect.

The metal wire 1 is a single-strand or multi-strand strong metal wire such as a copper wire. According to the actual demand, a single-stranded metal wire or a multi-stranded metal wire is adopted to meet different fixing strengths. When the metal wire is a multi-strand metal wire, the multi-strand metal wire is twisted with each other. The twisting of the multi-strand wires to each other further enhances the toughness.

In this embodiment, the insulating material layer 2 is a heat-shrinkable insulating material layer. The thermal shrinkage insulating material layer is insulating, anticorrosive and wear-resistant.

In this scheme, insulating material layer 2 is 10kV pyrocondensation insulating material layer.

In the scheme, the diameter of the metal wire 1 is 2mm-5 mm.

The practice of the present invention will be described with reference to specific embodiments.

Fig. 3 shows, the utility model discloses after passing the fixed orifices that insulating sheath reserved, twine mounting both ends together each other, buckle into a knot, realize insulating sheath's fixed.
