컷아웃 스위치 홀더구조{Holder ring device for a Cut-out-switch}Cutout switch holder structure {Holder ring device for a Cut-out-switch}

본 고안은 배전선로에 설치되어 전원접속을 차단하기 위한 컷아웃 스위치에 관한 것으로, 상세하게는 조작봉의 체결을 용이하게 할 수 있도록 컷아웃 스위치의 홀더를 개량한 컷아웃 스위치의 홀더구조에 관한 것이다.The present invention relates to a cutout switch installed in a distribution line to cut off the power supply connection, and more particularly, to a holder structure of a cutout switch in which the holder of the cutout switch is improved to facilitate the fastening of the operating rod. .

일반적으로 컷아웃 스위치는 배전선로나 변압기 1차측 또는 고객 수전설비등에 설치하여 배전선로 또는 주상변압기를 보호하거나 개폐하고 고장을 차단함으로써 배전선로 전체로 고장이 파급되는 것을 막아주는 역할을 한다.In general, the cutout switch is installed on the distribution line, the transformer primary side, or the customer's power receiving facility to protect or open the distribution line or the column transformer and block the failure to prevent the failure from spreading throughout the distribution line.

일반적으로 컷아웃 스위치는 그 홀더의 형상이 좁고 밀폐형인 환형상의 고리구조로 이루어져 있다. 종래에는 이러한 컷아웃 스위치를 조작하고자 할 경우 조작봉으로 컷아웃 스위치 홀더의 환형고리에 끼워서 조작하게 되는데 지상에서나 전주에 승주하여 컷아웃 스위치를 조작하고자 할 경우 조작봉의 길이와 무게로 인하여 작업자가 환형고리에 조작봉을 끼우기가 다소 어려운 상태이며, 특히 야간에는 주간 작업시보다 더욱 곤란하였고, 이에 따라 환형고리 밑에 조작봉을 위치시켜 불안전하게 조작(투입, 개방) 하는 등 설비사고와 안전사고가 발생할 우려가 항상 존재하고 있었다.In general, the cutout switch has a ring-shaped annular structure in which the holder is narrow and sealed. Conventionally, in order to operate such a cutout switch, the operation rod is inserted into an annular ring of the cutout switch holder. It is rather difficult to fit the operating rod into the hook, especially at night, which is more difficult than during daytime work. Therefore, the operation rod is placed under the annular ring, which causes unsafe operation (injection and opening). Concerns have always existed.

본 고안은 이러한 문제를 해결하기 위해 안출된 것으로, 상세하게는 컷아웃 스위치 홀더를 조작(개방, 투입)하기 위하여 홀더를 기존의 밀폐형에서 개방형 훅(HOOK)식으로 구조를 변형함으로써 작업자의 컷아웃 스위치 조작시 비정상적인 조작을 인하여 발생할 수 있는 설비사고 및 안전사고를 미연에 방지하고, 작업능률을 향상시킬 수 있도록 하는 컷아웃 스위치의 홀더구조를 제공하는데 그 목적이 있다.The present invention has been devised to solve such a problem, and in detail, the operator cuts out the structure by changing the structure of the holder from the conventional hermetic type to the open hook type in order to operate (open, insert) the cutout switch holder. It is an object of the present invention to provide a holder structure of a cutout switch that prevents equipment accidents and safety accidents that may occur due to abnormal operation during switch operation and improves work efficiency.

상기 목적을 달성하기 위한 본 고안은 고압선과 전기적으로 연결된 변압기 사이에 전원을 단속하기 위해 설치되는 접속단자와 통전봉을 갖는 컷아웃 스위치에있어서, 상기 통전봉의 상부에 프레임을 체결하고, 상기 프레임에 하부가 개구된 고정고리와 상기 고정고리의 개구부를 폐쇄하기 위한 가동편으로 이루어진 환형홀더가 체결되며, 상기 가동편은 상기 플레임에 고정된 판스프링에 의해 지지되는 것을 특징으로 하는 컷아웃 스위치의 홀더구조를 제공한다.The present invention for achieving the above object is a cutout switch having a conducting rod and a connection terminal is installed to interrupt the power supply between the high-voltage cable and the electrically connected transformer, fastening the frame on the top of the conducting rod, Holder of the cutout switch, characterized in that the annular holder consisting of a fixing ring having a lower opening and a movable piece for closing the opening of the fixing ring, the movable piece being supported by a leaf spring fixed to the flame. Provide structure.

이하, 본 고안의 바람직한 실시예를 첨부된 도면을 참조하여 상세하게 설명하기로 한다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 1 및 도 2는 본 고안에 따른 컷아웃 스위치의 설치구조를 보인 도면이다. 도 1을 참조하면, 일반적으로 전주(11)의 상단에 가로방향으로 완금(12)이 설치되고, 상기 전주(11)의 상면에 애자(13)를 매개로 고압전선(14)이 설치되며, 상기 전주(11)의 상단에 대하여 완금(12)으로부터 일정거리 이격된 하부에 변압기가 설치되는 구조를 갖고, 본 고안에 의해 개시되는 컷아웃 스위치(20)는 상기 완금(12)에 의해 지지되어 고압선(15)과 도시되지 않은 변압기에 사이에 상기 완금(12)에 의해 지지되어 있다.1 and 2 is a view showing the installation structure of the cutout switch according to the present invention. Referring to Figure 1, in general, the complete 12 is installed in the transverse direction at the top of the pole 11, the high-voltage wire 14 is installed on the upper surface of the pole 11 via the insulator 13, The transformer has a structure in which the transformer is installed at a lower part spaced apart from the finish 12 with respect to the upper end of the pole 11, the cutout switch 20 disclosed by the present invention is supported by the finish 12 It is supported by the stud 12 between the power cable 15 and a transformer (not shown).

도 3은 본 고안에 따른 컷아웃 스위치(20)의 구조를 상세하게 도시하고 있다. 도 2를 참조하면, 컷아웃 스위치(20)는 접속단자(21)의 하부에 통전봉(22)이 일체로 형성되며, 이 통전봉(22)의 상부에 프레임(23)을 체결하고, 상기 프레임(23)에 환형홀더(24)가 체결되는 구조를 갖는다.3 shows the structure of the cutout switch 20 according to the present invention in detail. Referring to FIG. 2, the cutout switch 20 has a conductive rod 22 integrally formed at a lower portion of the connection terminal 21, and fastens the frame 23 to the upper portion of the conductive rod 22. The annular holder 24 is fastened to the frame 23.

상기 환형홀더(24)는 하부가 개구된 고정고리(25)와 상기 고정고리(25)의 개구부를 폐쇄하기 위한 가동편(26)으로 구성된다. 상기 가동편(26)은 그 끝단부가 프레임(23)에 고정된 탄성이 강한 판스프링(27)에 체결된 구조를 갖고, 조작봉(30)으로 가동편(26)을 밀어 올릴 경우 판스프링(27)의 힘으로 위로 올라갔다가 판스프링의 복원력에 의해 원위치로 복원하게 된다.The annular holder 24 is composed of a fixing ring 25 having a lower opening and a movable piece 26 for closing the opening of the fixing ring 25. The movable piece 26 has a structure in which an end portion thereof is fastened to a highly elastic plate spring 27 fixed to the frame 23, and when the movable piece 26 is pushed up by the operation rod 30, the plate spring ( 27) up by the force of the force is restored to the original position by the restoring force of the leaf spring.

이러한 구성에 의하면, 본 고안은 변압기에 인가되는 고압을 차단하고자 할 경우 환형고리에 조작봉(30)의 고리부재(31)를 끼워서 삽입하지 않고 고리부재(31)로 가동편(26)을 밀어 올려 환형홀더(24)에 체결한 후 조작봉(30)을 하방으로 끌어 당기게 되면 접속단자(21)가 전극단자로부터 이탈되어 전원이 차단되고, 이러한 상태에서 작업이 완료되면 조작봉(30)을 밀어올려 전극단자에 접속단자(21)를 체결함으로써 전원이 인가되며, 이후 조작봉(30)의 고리부재(31)를 수평방향으로 이동시켜 환형홀더(24)로부터 조작봉을 분리하게 된다.According to this configuration, the present invention is to push the movable piece 26 to the ring member 31 without inserting the ring member 31 of the operating rod 30 in the annular ring to block the high pressure applied to the transformer After pulling up the annular holder 24 and pulling the operation rod 30 downward, the connection terminal 21 is separated from the electrode terminal and the power is cut off. When the operation is completed in this state, the operation rod 30 is opened. Power is applied by pushing up and connecting the connection terminal 21 to the electrode terminal, and then moving the ring member 31 of the operating rod 30 in the horizontal direction to separate the operating rod from the annular holder 24.

이상에서 보는 바와 같이 본 고안에 따른 컷아웃 스위치 홀더고리 구조는 기존의 밀폐형에서 개방형 훅식으로 구조를 개선함으로써 작업자의 컷아웃 스위치 조작시 비정상적인 조작을 인하여 발생할 수 있는 설비사고 및 안전사고를 미연에 방지하고 작업능률을 향상시키는 효과가 있다.As seen above, the cutout switch holder ring structure according to the present invention improves the structure from the conventional closed type to the open hook type to prevent equipment accidents and safety accidents that may occur due to abnormal operation when the operator cutout switch. It is effective to improve work efficiency.
