Abstract

<P>PROBLEM TO BE SOLVED: To solve the problem that the end part of a conventional wrap bind tightly contacts with a high-voltage insulation electric wire, and a very long work hours are required to remove the bind from the high-voltage insulation electric wire by operating a hot stick, resulting in degradation in work efficiency, and that, especially in a soilure district such as a salt damage district, the tight contacting of the end part to the high-voltage insulation electric wire causes concentration of a leakage current from the high-voltage insulation electric wire on both ends of the end part, resulting in a tracking phenomenon. <P>SOLUTION: A steel band of an appropriate thickness and width is worked into spiral, which is insulation-coated, and thus the high-voltage insulation electric wire can contact with the bind by surface, for improved gripping force and a shorter bind. An appropriate space is provided between the bind end part and the high-voltage insulation electric wire, for easy removing operation and for preventing tracking. <P>COPYRIGHT: (C)2004,JPO

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a winding stick for a hot stick, and is used as a material for fixing a high-voltage insulated wire to a high-voltage insulator of a high-voltage distribution line. Used for facilitating hot stick operation in fixing / removing work. [0002] Conventional winding binding is a high tension single wire,
Alternatively, the stranded wire is formed and covered, but the end is in close contact with the high-voltage insulated wire and the operation of a hot stick removes this binding from the high-voltage insulated wire, which significantly increases the work time and increases work efficiency. Inhibiting. Also,
In the case of a single wire bind, the high-voltage insulated wire and the bind are in linear contact, and the gripping effect is smaller than that of the planar contact. further,
The tight contact of these bind ends with the high-voltage insulated wires may cause leakage current from the high-voltage insulated wires to concentrate on both ends of the ends, particularly in contaminated areas such as salt-damaged areas, causing a tracking phenomenon and damaging the high-voltage insulated wires. And cause radio interference. [0003] The conventional winding binding has a problem in that when its end is in close contact with a high-voltage insulated wire and it is removed with a hot stick, it takes a considerable amount of time to work, and the occurrence of tracking is large. have. As a solution to this problem, there is provided a winding stick for a hot stick which grips a high-voltage insulated wire by processing a steel strip having an appropriate width and thickness into a spiral shape and applying an insulating coating. [0004] As means for solving the above-mentioned problems, a high-strength steel strip having an appropriate width and thickness is processed into a spiral shape, and is insulated and coated, so that a high-voltage insulated wire and a bind are conventionally used. By making the linear contact into a planar contact, the gripping force is improved, the binding is shortened, and an appropriate space is provided between the end of the binding and the high-voltage insulated wire, making removal work more efficient and preventing tracking. It is intended. [0005] The operation of the present invention will be described. Since the tip of the present bind has a suitable space with the high-voltage insulated wire, the tip tool of the hot stick can easily be connected between the bind and the high-voltage insulated wire. And the binding can be easily removed. Also, the binding tip is rounded,
In addition, since there is a space between both ends of the bind and the high-voltage insulated wire, the leakage current from the high-voltage insulated wire is distributed to the bind compared to the conventional one, reducing the occurrence of tracking, and Damage and radio interference can be prevented. [0006] This embodiment will be described below with reference to the drawings.
FIG. 1 shows an overall view of a first embodiment of a hot-stick winding bind, and FIG. 2 shows a state in which a high-voltage insulator is gripped by a hot-stick winding bind on a high-voltage insulator. 1 is a high-strength steel strip with an appropriate thickness and width that is processed into a spiral shape and coated with insulation to hold a high-voltage insulated wire. 2 is an annular part of this bind and fixed to a high-voltage insulator. 3 is an insulation coating. Reference numeral 4 denotes a shape in which the spiral is widened so that a space is provided between the high-voltage insulated wires and the bind at both ends, which makes it easier to insert the tip tool of the hot stick and has an effect on improving the work efficiency. Due to the roundness, this synergistic effect has the function of dispersing the leakage current from the high-voltage insulated wire and suppressing tracking. Reference numeral 6 denotes a core wire of a conventional bind steel wire. By adopting the hot-stick wrapping binding, workability is improved and tracking is suppressed. [0007] The use of the present hot-stick wrap binding significantly contributes to the improvement of the efficiency of hot-stick work much more than the current grip, and reduces the work load and the safety of work on the pole worker, and furthermore, In addition, it is possible to suppress the occurrence of tracking, extend the replacement work of the high-voltage insulated wire, and prevent radio interference.
