In particular, a fire occurs due to an external discharge. The invention also relates to a distribution arrester which prevents the problem of internal flashover due to the penetration of moisture.
최근들어 계통전압의 승압에 따른 초고압화가 이루어져 배전계통이 복잡하게 됨에 따라 배전선로상에서 발생되는 낙뢰나 선로개폐 등으로 인해 이상 과전압(transient voltage surge)이 유발되는 경우가 있다. 이와같이 유기된 이상 과전압은 배전선로상에 설치되어 있는 각종 배전기기들의 손상을 초래할 뿐만 아니라 전력 수용가로 침입하여 각종 전기기기들을 파괴하거나 수명을 단축시킨다.Recently, due to the voltage increase of the ultra-high voltage to increase the complexity of the distribution system, there is a case that a transient voltage surge is caused by lightning or line opening and the like generated on the distribution line. This abnormal overvoltage induced not only causes damage to various distributors installed on the distribution line, but also breaks into electric power consumers and destroys various electrical devices or shortens the lifespan.
이러한 문제점을 극복하기 위해서 배전용 피뢰기(Power arrester)가 사용되는데, 상기 배전용 피뢰기는 이상 과전압의 발생시 이를 접지측으로 방전시켜 이상과전압 상태를 해소시켜준다.In order to overcome this problem, a power arrester is used, and when a faulty overvoltage occurs, it is discharged to the ground side to solve the faulty overvoltage state.

The other end of the polymer insulating housing 40 is also provided. The connector 120 penetrates vertically and is connected to the other spacer 30. An insertion fixing hole 121 is formed at one side of the connector 120.
상기 연결구(120)의 삽입고정공(121)에는 인입케이블(130)의 일단이 삽입ㆍ압착되어 연결되며, 상기 폴리머절연하우징(40)과 연결구(120) 및 인입케이블(130)의 결합부위 둘레에는 고무몰드콘(140)이 감싸져 있으며, 결합력을 강화하기 위해 고무몰드가 형성되는 폴리머절연하우징(40)의 외주에는 결합요홈(41)을 형성하는 것이 바람직하다.One end of the inlet cable 130 is inserted and connected to the insertion fixing hole 121 of the connector 120, and the circumference of the coupling portion between the polymer insulating housing 40, the connector 120, and the inlet cable 130 is fixed. In the rubber mold cone 140 is wrapped, it is preferable to form a coupling groove 41 on the outer circumference of the polymer insulating housing 40 in which the rubber mold is formed to strengthen the bonding force.
상기와 같은 피뢰기를 제작하기 위해서는 먼저 폴리머절연하우징(40)을 일차로 인서트 성형한 후, 삽입고정공(121)에 인입케이블(130)의 일단을 삽입ㆍ압착한 연결구(120)를 스페이서(30)에 접속시키고, 상기 고무몰드콘(140)을 이차로 인서트 성형하면 간편하고 신속하게 본 고안에 따른 배전용 피뢰기를 제작할 수 있다.In order to manufacture the lightning arrester as described above, first, the polymer insulating housing 40 is first insert-molded, and then the connector 120 in which one end of the inlet cable 130 is inserted and crimped into the insertion fixing hole 121 is spaced from the spacer 30. ) And the insert molding the rubber mold cone 140 can be easily and quickly produced a lightning arrester according to the present invention.
도 3은 도 2에 도시된 배전용 피뢰기의 설치상태를 나타낸 도면으로, 피뢰기와 일체로 형성된 인입케이블(130)의 단부를 배전선로(도시되지 않음)에 연결하고, 상기 볼트형 접지전극(70)에는 절연브라켓(90)이 삽입된 상태에서 단로기(100)를 연결하며, 상기 단로기(100)에는 접지선(110)을 연결한다. 따라서, 별도의 연결케이블을 사용하지 않고서도 본 고안에 따른 배전용 피뢰기를 배전선로에 연결할 수 있다.FIG. 3 is a view illustrating an installation state of the lightning arrester shown in FIG. 2. The end of the lead cable 130 formed integrally with the arrester is connected to a distribution line (not shown), and the bolt-type ground electrode 70 is connected. ) Connects the disconnecting device 100 in a state in which the insulating bracket 90 is inserted, and connects the ground wire 110 to the disconnecting device 100. Therefore, the lightning arrester according to the present invention can be connected to the distribution line without using a separate connecting cable.
한편, 연결케이블과 터미널전극의 결합부를 몰드콘 타입으로 제작함에 따라 결합부위가 외부로 노출되지 않아 조류의 접촉으로 인해 발생되는 피뢰기간의 단락은 방지되며, 또한 외부방전이 방지되고 내부섬락이 일어나는 것을 막아준다.On the other hand, as the coupling portion of the connecting cable and the terminal electrode is manufactured in a mold cone type, the coupling portion is not exposed to the outside, thereby preventing a short circuit of the lightning protection period caused by the contact of birds, and also preventing external discharge and causing internal flashover. Prevent it.
아울러, 고무몰드가 형성되는 폴리머절연하우징(40)의 외주에 결합요홈(41)을 형성하여 고무몰드콘(140)과 폴리머절연하우징(40)을 견고하게 결합하고, 스페이서(30)의 외측단부를 폴리머절연하우징(40)이 감싸도록 형성함에 따라 스페이서(30)를 통한 습기의 침투는 방지된다.In addition, the coupling groove 41 is formed on the outer circumference of the polymer insulating housing 40 in which the rubber mold is formed, thereby firmly coupling the rubber mold cone 140 and the polymer insulating housing 40 to the outer end of the spacer 30. As the polymer insulating housing 40 is formed to wrap, penetration of moisture through the spacer 30 is prevented.

The problem of internal flashover due to moisture infiltration has been eliminated.
또한, 연결케이블을 피뢰기와 일체로 제작하여 별도의 연결케이블을 사용하지 않음에 따라 피뢰기의 설치원가를 대폭 절감시키고, 고무몰드가 형성되는 폴리머절연하우징의 외주에 결합요홈을 형성하여 고무몰드콘을 폴리머절연하우징에 견고하게 결합하며, 아울러 스페이서의 외측단부를 폴리머절연하우징이 감싸도록 형성함에 따라 습기의 침투로 인해 피뢰기가 손상되는 것을 방지할 수 있다.In addition, since the connecting cable is manufactured integrally with the arrester, the installation cost of the arrester is greatly reduced by not using a separate connecting cable, and the rubber molding cone is formed by forming a coupling groove in the outer circumference of the polymer insulation housing in which the rubber mold is formed. It is firmly coupled to the polymer insulating housing, and the outer end of the spacer is formed to surround the polymer insulating housing, thereby preventing damage to the lightning arrester due to moisture penetration.
