Abstract
Description
본 발명은 전력기기의 송전선에 이용되는 고분자제 애자에 관한 것이다.The present invention relates to a polymer insulator for use in power transmission lines of power equipment.
도 2에 종래의 고분자 애자의 일례를 나타낸다.2 shows an example of a conventional polymer insulator.
양단에 금속제의 금구(1)가 부착된 FRP 봉(2)의 주위에는 고무 피복(3) 및 고무로 형성된 칼날상의 갓(4)이 형성되어 있으며, 이 고무로 형성된 칼날상의 갓(4)의 내측에는 동일한 고무로 형성된 컵형상의 갓(5)이 설치되어 있다.A rubber sheath 3 and a blade-shaped cap 4 formed of rubber are formed around the FRP rod 2 with metal brackets 1 attached to both ends thereof. The cup-shaped shade 5 formed of the same rubber | gum is provided inside.
여기서, 컵형상이란 개구부의 내경에 대하여 개구부 입구에서 내측 바닥까지의 길이(깊이)의 비가 1이상이며, 또한 측면에 일부 직선부분을 갖는 형상의 것으로 정의한다.Here, the cup shape is defined as a shape having a ratio of one or more lengths (depths) from the inlet opening to the inner bottom with respect to the inner diameter of the opening and having some straight portions on the side.
컵형상의 갓(5)의 앞에 위치한 고무로 성형된 칼날상의 갓(4)은 컵형상의 갓(5)의 입구로부터 빗물이 들어가기 어렵게 하기 위한 역할을 한다. 이에 의해 우천시에도 컵형상의 갓(5)의 외측은 빗물에 의해 젖으나, 내측은 젖지 않고 건조한 부분을 형성하기 쉽게 되므로, 우천시에도 누설전류가 흐르기 어렵게 되어 결과적으로 신뢰성이 있는 고전압용의 애자를 제공하는 것이 가능하다.The rubber-shaped blade shade 4 formed in front of the cup-shaped shade 5 serves to make rainwater difficult to enter from the inlet of the cup-shaped shade 5. As a result, even when it is rainy, the outside of the cup-shaped shade 5 is wetted by rain water, but the inside is not wet, and it is easy to form a dry part, so that leakage current is difficult to flow even in rainy weather. It is possible to provide.
도 3은 종래의 고분자제 애자의 다른 예를 나타낸다.3 shows another example of a conventional polymer insulator.
양단에 금속제의 금구(1)가 부착된 FRP 봉(2)의 주위에는 고무 피복(3) 및 고무로 형성된 컵형상의 갓(5)이 부착되어 있으며, 이 컵형의 갓(5)의 내측에는 동일한 고무로 형성된 칼날상의 갓(4)이 설치되어 있다.A rubber sheath 3 and a cup-shaped cap 5 formed of rubber are attached to the periphery of the FRP rod 2 having metal brackets 1 attached to both ends thereof. A blade-shaped shade 4 formed of the same rubber is provided.
이 구조에 있어서도 도 1과 동일하게 작용하는 것을 나타내며, 우천시에도 컵형의 갓(5)의 외측은 비에 의해 젖으나, 내측은 젖지 않고, 건조한 부분을 형성하기 쉽게 되므로 우천시에도 누설 전류가 흐르기 어렵게 되어 결과적으로 신뢰성이 있는 고전압용의 애자를 제공할 수 있다.Also in this structure, it shows the same function as FIG. 1, and even when it is rainy, the outside of the cup-shaped shade 5 is wetted by rain, but the inside is not wet, and it is easy to form a dry part, so that leakage current is difficult to flow even in rainy weather. As a result, it is possible to provide a reliable high voltage insulator.
그러나, 상기 종래 구조에서 고무를 형성하는 경우, 컵형상의 갓(5)의 앞에 고무로 성형된 칼날상의 갓(4)을 설치한 구조로 되어 있기 때문에, 성형후 성형품을 꺼내어 컵형상의 갓(5)의 가운데 넣어져 있는 성형용의 중자(中子)를 꺼낼 수 없고, 이 때문에 일체로 성형할 수 없었다. 따라서, 이러한 형태를 성형하기 위해서는 처음에 칼날상의 갓(4)과 FRP 봉(2)의 고무 피복(3) 부분을 일체로 성형하고, 다음에 컵형상의 갓(5)을 별도로 성형한다. 그리고 이 컵형의 갓(5)을 고무 피복(3)의 위에 설치하고 접착제 등으로 고정한다.However, in the case of forming the rubber in the conventional structure, the rubber shaped bladed shade 4 is provided in front of the cup shaped shade 5, so that the molded article is removed after the molding and the cup shaped shade ( The middle part for shaping | molding put in the middle of 5) could not be taken out, and for this reason, shaping | molding could not be carried out integrally. Therefore, in order to mold such a shape, first, the blade-shaped shade 4 and the rubber coating 3 portion of the FRP rod 2 are integrally formed, and then the cup-shaped shade 5 is separately formed. And this cup-shaped shade 5 is installed on the rubber coating 3 and fixed with an adhesive agent or the like.
이와 같이, 상기 종래 구조에서 고무를 성형하는 경우 전체를 동시에 일체로 성형할 수 없기 때문에 성형을 2단계로 나누어 행하고, 또는 다시 접착하는 공정으로 인하여 제조비용이 높고, 접착부분의 장기 신뢰성에도 문제가 있었다.As described above, when the rubber is molded in the conventional structure, since the whole cannot be molded at the same time, the molding is divided into two stages, or the manufacturing process is high due to the process of bonding again, and there is a problem in the long-term reliability of the bonded portion. there was.

고무로 성형된 갓에 대하여 밥공기 형상을 가지며, 이 밥공기 형상을 갖는 갓에 대하여 뚜껑을 하는 방향으로 칼날상의 고무 갓을 형성한다. 여기서 밥공기 형상이란 단면에 대하여 내측이 R형상을 가지며 또한 외측으로 부풀은 구조를 나타낸다.It has a rice bowl shape with respect to the rubber | gum molded with rubber | gum, and a blade shaped rubber | gum | shape rubber | gum is formed in the direction which makes a lid with respect to this rice ball | shape with rice bowl shape. Here, the rice bowl shape refers to a structure in which the inner side has an R shape and bulges outward.
도 1에 본 발명의 실시 형태의 일례를 나타낸다.An example of embodiment of this invention is shown in FIG.
양단에 금속제의 금구(1)가 코킹 압착에 의해 부착된 FRP 봉(2)에 소정의 두께를 갖는 고무 피복(3)을 형성하고, 이 고무 피복(3)의 금구(1) 측에는 고무로 형성된 밥공기 형상의 갓(6)이 형성되며, 이 고무로 형성된 밥공기 형상의 갓(6)의개구부의 방향은 금구(1)와는 반대방향으로 향하고 있다. 또한, 밥공기 형상의 갓(6)의 개구부 방향으로 칼날상의 갓(4)이 형성되어 있으며, 이 고무로 형성된 밥공기 형상의 갓(6)과 칼날상의 갓(4)의 위치관계는 밥공기 형상의 갓(6)에 대하여 정확한 뚜껑을 하는 방향으로 칼날상의 갓(4)이 구성되어 있다.A metal sheath 1 on both ends is formed with a rubber sheath 3 having a predetermined thickness on the FRP rod 2 to which the metal sheath 1 is attached by crimping crimping, and the metal sheath 1 of the rubber sheath 3 is formed of rubber. A rice bowl-shaped lampshade 6 is formed, and the direction of the opening of the rice bowl-shaped lampshade 6 formed of this rubber is directed in the opposite direction to the bracket 1. Moreover, the blade-shaped lampshade 4 is formed in the opening direction of the rice-shaped lampshade 6, and the positional relationship of the rice-shaped lampshade 6 and the blade-shaped lampshade 4 formed with this rubber | gum is a rice bowl. The blade-shaped shade 4 is configured in the direction of making a correct lid with respect to the shaped shade 6.
본 발명의 고분자제 애자를 성형할 경우, 성형 전에 밥공기 형상의 갓(6)의 내측 접촉 부분에 형 성형용의 중자(中子)를 설치한다. 그리고 성형 후, 제품을 금형으로부터 꺼내고, 밥공기형 형상의 갓(6) 내에 넣어져 있는 중자를 꺼낼 때, 중자는 2개로 분할되어 있고, 내측에 있는 칼날상의 갓(4)은 고무제이므로 용이하게 구부러질 수 있으므로, 성형후 이 중자를 꺼내는 경우, 2개로 분할된 중자를 90°회전할 수 있고, 이에 의해 중자를 간단히 꺼내는 것이 가능하다.In the case of molding the polymer insulator of the present invention, a core for mold molding is provided in the inner contact portion of the rice-shaped shade 6 before molding. And after shaping | molding, when taking out a product from a metal mold | die, and taking out the core which was put in the rice bowl-shaped shade 6, the middle core is divided into two, and since the blade-shaped shade 4 of the inner side is made of rubber, it is easy Since the core can be taken out after molding, the core divided into two can be rotated by 90 degrees, thereby making it possible to simply take out the core.
이 구조에 있어서, 우천시에도 밥공기 형상의 갓의 외측은 비에 의해 젖으나, 내측에는 밥공기형 형상의 앞에 있는 칼날상의 갓이 뚜껑 역할을 하기 있기 때문에 우수가 이 밥공기 형상의 갓의 내측으로 들어가기 어렵고, 마른 부문을 형성하기 쉽게 되므로, 우천시에도 누설전류가 흐르기 어렵게 되어 결과적으로 신뢰성이 있는 고전압용의 애자를 제공할 수 있다.In this structure, even when it is rainy, the outside of the rice bowl-shaped lampshade is wet by rain, but the inside of the rice bowl-shaped lampshade is excellent because the blade-shaped lampshade in front of the rice bowl shape serves as a lid. Since it is difficult to enter and the dry section is easily formed, leakage current is less likely to flow even in rainy weather, resulting in a reliable high voltage insulator.
또한, 성형에 있어서도, 실리콘 고무로 성형하는 경우, 전체를 동시에 일체로 성형할 수 있기 때문에 지금까지와 같이 성형을 2단계로 나누어 행하거나 다시 갓을 접착하기 위하여 접착공정을 행할 필요가 없으므로 제조비용이 싸고, 또한 종래 문제가 되었던 접착부분에서의 장기 신뢰성에도 문제가 없는 고분자제 애자를 제공할 수 있다.Also in molding, when molding with silicone rubber, the whole can be molded in one piece at the same time, so that it is not necessary to divide the molding into two stages as before, or to perform the bonding step to bond the lamp again. It is possible to provide a polymer insulator which is inexpensive and has no problem in long-term reliability at the bonding portion, which has become a problem in the past.
