Abstract

The invention discloses a wire rod insulating sleeve and a corresponding assembly. The pole insulating sleeve can be sleeved on a cement pole so as to insulate the cement pole from a wire support again, and thus, the occurrence of ground fault is effectively prevented.

Description

Insulating cover of wire pole and insulating wire pole subassembly

Technical Field

The invention relates to the field of telegraph poles, in particular to a wire pole insulating sleeve and an insulated wire pole assembly.

Background

The cement utility pole is a common utility pole, and is supported by reinforced concrete, and a wire support is erected on the cement utility pole, and an insulated terminal is mounted on the wire support, and a wire is erected on the insulated terminal. But the cement wire pole has electric conductivity, and under the condition such as the bird's nest or bad weather left on the ageing damage of insulated terminal, the electric wire frame, the condition of the electric wire support short circuit of electric wire and metal material can take place to through cement wire pole ground connection, thereby cause accidents such as power failure, and the ground point often is difficult to seek in the short time, can not in time resume the power supply. In order to solve this problem, an asymmetric current source (such as the new patent ZL201220448758.8) is provided to search for a grounding point, and the grounding point is found and then repaired. However, this method can only be used for remediation after grounding, and cannot fundamentally prevent the occurrence of grounding accidents. Therefore, there is a great need in the art for a technique that can fundamentally solve the ground fault of the wire.

Disclosure of Invention

An object of the present invention is to provide a pole insulation cover which can be fitted over a cement pole to re-insulate the cement pole from a wire support, or which can be of a two-body structure, with the upper insulation and the lower insulation cap lower body structure, and thus effectively prevent ground faults.

In order to achieve the purpose, the invention adopts the following technical scheme:

the utility model provides an insulating cover of line pole, insulating cover of line pole includes the barrel, the barrel top is sealed, leaves the opening in the bottom, the side between barrel top and the bottom is the toper side to leave tubaeform shirt rim in the bottom, the barrel is insulating barrel.

The bottom of the cylinder body is connected with the connecting part of the horn-shaped skirt by an insulating part.

Preferably, the cylinder is an insulated glass fiber reinforced plastic cylinder, an insulated hard rubber cylinder or an insulated hard plastic cylinder.

It is another object of the present invention to provide an insulated pole assembly including a concrete pole and the above-described pole insulator sleeve used in conjunction therewith, thereby substantially precluding ground contact accidents. The method is realized by the following scheme:

an insulated pole assembly comprising a cement pole and further comprising the pole insulation sleeve of

claim

1 or 2, wherein the pole insulation sleeve has a length of 2-3 meters and is sleeved on the upper end of the cement pole, and the inner wall of the tapered side surface of the cylinder body is attached to the outer wall of the tapered side surface of the upper end of the cement pole.

The device solves the problem that the grounding of the telegraph pole is different from the traditional thinking, and the single-phase grounding accident is thoroughly avoided by erecting an insulating layer on the cement telegraph pole and the electric wire bracket. The top of the insulating sleeve is sealed to prevent rainwater from entering, and the horn-shaped skirt at the lower part can enable rainwater to spread around, so that short circuit caused by rainwater is avoided. The whole device has extremely simple structure, but can well solve the single-phase grounding accident. The insulating sleeve is made of glass fiber reinforced plastic, hard rubber, plastic and other insulating parts, and the requirements on the hardness and the strength of the electric wire support mounting are met.

Drawings

FIG. 1 is a schematic view of the structure of an insulating sleeve according to the present invention;

fig. 2 is a schematic view of the combined structure.

Detailed Description

The invention will be further described with reference to the accompanying drawings:

as shown in fig. 1 and 2, the wire rod insulating sleeve of the invention comprises a cylinder body 1, wherein the top 2 of the cylinder body 1 is sealed and prevents rainwater from entering, an opening 3 is reserved at the bottom, the side surface between the top and the bottom of the cylinder body 1 is a tapered side surface 4, and a flared skirt 5 is reserved at the bottom. The cylinder 1 is made of an insulating material with mechanical strength and hardness, such as glass fiber reinforced plastic, hard rubber, plastic and the like, and needs to meet the requirements of strength, hardness, service life and the like of an electric wire mounting bracket. The length of general insulating cover is 2 ~ 3 meters, overlaps on cement wire pole 6 from opening 3 during the use, makes the toper side inner wall of insulating cover and the outer coin of the toper side in cement wire pole upper end laminate mutually. Then the wire bracket can be installed, the wires can be erected and the like.

Through the in-service use, this insulating cover and insulated wire pole subassembly not only simple structure, the preparation of being convenient for, the cost is lower, installation convenient to use moreover, only need the cover can erect support and electric wire at the electric wire pole tip, can finely solve the power failure scheduling problem that electric wire and earth short circuit caused. Under the condition that the pole easily produces electric leakage phenomenon such as rainy day, causes the casualties, install additional this device of use, can avoid the pole to electrically conduct downwards, greatly reduce danger.

The above embodiments are merely illustrative of the concept and implementation of the present invention, and are not restrictive, and technical solutions that are not substantially changed under the concept of the present invention are still within the scope of protection.
