Description

하이브리드 지지애자 및 그 제조방법 {HYBRID POST INSULATOR AND MANUFACTURING METHOD THEREOF}Hybrid support insulator and its manufacturing method {HYBRID POST INSULATOR AND MANUFACTURING METHOD THEREOF}

본 발명은 직류 선로의 경량 전철에 전차선을 지지하고 전기적 절연을 위해 복합 재료를 사용한 하이브리드 지지애자에 관한 것으로, 경량 전철 지지 애자 뿐 아니라 기존에 사용 중인 직류, 교류용 모든 자기재 지지 애자류에 적용이 가능하며 송, 배전 선로 및 철도, 지하철, 발전소, 변전소용 지지 애자류에 적용 가능한 하이브리드 지지애자 및 그 제조방법에 관한 것이다.The present invention relates to a hybrid support insulator using a composite material for supporting a catenary line in a lightweight train of a direct current line and for electrical insulation, and is applied to all magnetic material supporting insulators for direct current and alternating current in use as well as a lightweight train support insulator. It is possible and relates to a hybrid support insulator applicable to support insulators for transmission and distribution lines and railways, subways, power plants, and substations, and a method of manufacturing the same.

송전선로에서 전선을 기계적으로 고정시키는 동시에 전기적 절연을 위해 사용되는 애자는 절연체의 재료에 따라 자기애자, 유리애자, 에폭시 애자로 크게 구분 된다.Insulators used for electrical insulation while mechanically fixing electric wires in transmission lines are largely classified into magnetic insulators, glass insulators, and epoxy insulators depending on the material of the insulator.

선로의 신뢰성을 결정하는 중요한 역할을 담당하고 있으며, 전기가 실용화된 100년 이래로 고전압 절연물인 애자는 자기가 사용되어 왔다.It plays an important role in determining the reliability of the line, and since the 100 years when electricity became practical, insulators, which are high-voltage insulators, have been used with porcelain.

종래의 애자는 주로 자기를 이용하여 제작되었으며, 이러한 자기를 사용할 경우 기계적 강도와 절연성능은 우수하나, 운반 및 취급 시에도 쉽게 깨질 수 있다는 문제점이 있으며, 먼지가 쌓이게 되는 경우나 바닷가와 같은 곳에서는 염분이 적층 되는 경우, 누설전류에 의한 섬락이 발생하게 되어 쉽게 파손될 수 있다는 문제점이 있으며, 자기 내부에 장착되는 도체인 핀 볼트와의 절연거리가 짧아 애자의 내부에 전기적 응력집중현상이 발생하게 되어 장시간 사용시 절연파괴가 발생하거나, 응력이 집중함에 따라 제조결함으로 인한 크랙 파손이 발생하여 선로사고가 빈번히 발생하였다.Conventional insulators were mainly manufactured using magnetism, and if such magnetism is used, mechanical strength and insulation performance are excellent, but there is a problem that it can be easily broken even during transportation and handling, and in cases where dust accumulates or in places such as beaches, When salt is stacked, there is a problem that flashover occurs due to leakage current and can be easily damaged, and because the insulation distance from the pin bolt, which is a conductor mounted inside, is short, an electrical stress concentration phenomenon occurs inside the insulator. Insulation breakdown occurred when used for a long time, or crack breakage occurred due to manufacturing defects due to concentration of stress, leading to frequent line accidents.

이러한 문제점을 해결하고자 1950년대 폴리머 재질의 애자가 개발되어 사용되고 있으나, 자기애자에 비해 중량이 가벼워 취급하기 쉽고, 운반이나 취급 또는 섬락 현상에 의한 파손은 방지할 수 있었으나, 내부 코어(Core)는 섬유강화 플라스틱(FRP)로 구성되고 외피 하우징(Housing)은 실리콘 재질로 사출 성형 후 내부 코어 FRP를 금구로 압착하는 구조로 전선이 안착되는 부분이 폴리머로 제조됨에 따라서 기계적인 강도가 약해서 쉽게 전선이 빠질 수 있는 문제점이 있었다.In order to solve this problem, polymer insulators were developed and used in the 1950s, but they were lighter in weight than magnetic insulators, so they were easier to handle, and damage caused by transportation, handling or flashover could be prevented. It is composed of reinforced plastic (FRP), and the outer housing is made of silicon, and the inner core FRP is pressed with a bracket. As the part where the wire is seated is made of polymer, the mechanical strength is weak and the wire is easily removed. There was a problem that could be.

따라서 본 발명이 이루고자 하는 기술적 과제는 자기애자의 기계적 강도와 우수한 절연성능을 가지면서 폴리머 애자의 경량, 운반이나 취급 또는 섬락 현상에 강한 하이브리드 지지애자 및 그 제조방법을 제공하기 위한 것이다.Accordingly, a technical problem to be achieved by the present invention is to provide a hybrid support insulator and a method of manufacturing the same, while having the mechanical strength and excellent insulating performance of the narcissus insulator, light weight of the polymer insulator, and strong against transport, handling or flashover.

It provides a structured hybrid support insulator and a method of manufacturing the same.

이러한 특징에 따르면, 본 발명은 기존 자기애자 폴리머 애자의 단점을 보완하여 자기코어 몸체에 홀(hole)이 형성되도록 성형하여 가벼운 중량이면서 홀(hole) 내부에 섬유강화플라스틱(FRP)을 구비하여 진동 발생 시 반복되는 진동하중에 견디고 피로 특성이 양호하며 내충격성(내열성, 내한성)이 증강되고 크랙으로 인한 사고를 방지할 수 있으며, 외피 하우징은 전기적 특성과 표면 발수성이 우수한 실리콘 재질로 외부적인 충격에 의한 크랙이나 파손을 방지할 있으며, 자기재 코어와 일체형으로 사출성형을 하므로 계면현상을 억제할 수 있다.According to these features, the present invention is formed to form a hole in the magnetic core body by supplementing the shortcomings of the existing magnetic insulator polymer insulator, and has a light weight and fiber reinforced plastic (FRP) inside the hole to vibrate. When it occurs, it withstands repeated vibration loads, has good fatigue properties, improves impact resistance (heat resistance, cold resistance) and prevents accidents due to cracks. It can prevent cracks or damage caused by, and can suppress interfacial phenomena because it is injection-molded integrally with the magnetic material core.
