본 발명은 특고압 전선용 무정전 절연커버구조에 관한 것으로서, 상세하게는 특고압 전선의 설치 작업시에 힌지로 연결된 절연커버를 볼트 체결하여 특고압 전선의 피복 노출부 부위를 감싼 채 절연커버에 연결된 레버를 회동하여 특고압 전선을 가압한 상태로 연결되게 함으로써 설치 작업의 편리성과 신속성을 제공하는 특고압 전선용 무정전 절연커버구조에 관한 것이다.
The present invention relates to an uninterruptible insulated cover structure for an extra high voltage wire, and in detail, the bolt is fastened to an insulation cover connected by a hinge during installation of the extra high voltage wire, and is connected to the insulated cover while covering an exposed portion of the extra high voltage wire. The present invention relates to an uninterruptible insulation cover structure for an extra-high voltage wire that provides convenience and speed of installation by rotating the lever so that the extra-high voltage wire is pressurized.

종래에는 일반적으로 일관작업을 하는 공장 등에서는 정전이 되면 생산라인에 많은 문제를 가져오게 되므로, 전기공사를 할 경우에는 정전시키지 않고 공사하는 무정전 작업을 많이 하게 된다.In the past, in general, such as a factory that works consistently, if a power outage brings a lot of problems to the production line, in the case of electrical work, there is a lot of uninterrupted work to be done without power failure.

이렇게 무정전 작업을 할 경우에는 특고압전선의 일부에 피복을 제거하고, 이 피복이 제거된 부위에는 클램프로 바이패스 케이블 헤드를 연결하여 작업하게 된다.In the case of uninterrupted work, the cover is removed from a part of the extra high voltage wire, and the bypass cable head is connected to the part where the cover is removed by a clamp.

그리고, 무정전 작업을 끝낸 후에는 피복을 제거한 부위에는 분기슬리브 커버를 취부하여 특고압전선을 절연하게 된다.After the uninterrupted work is completed, a branch sleeve cover is attached to the portion where the coating is removed to insulate the extra high voltage wire.

그러나, 종래에는 무정전 작업시 특고압전선의 임의의 장소에 피복을 제거한 후 분기슬리브 커버를 취부하고 있으므로, 무정전 작업의 증가로 인하여 특고압전선의 피복제거에 따른 분기슬리브 커버의 취부개소가 증가하게 되어, 도시미관을 해친다는 문제점이 있었다.However, in the prior art, since the branch sleeve cover is mounted after removing the cover at any place of the extra-high voltage cable during the uninterruptible work, the branch sleeve cover is increased due to the increase in the uninterruptible work. There was a problem that it hurts the city view.

또한, 작업방법이 표준화되어 있지 않으므로, 임의의 개소에서 피복을 제거하여 무정전 작업 및 분기슬리브 커버의 취부작업을 하게 되면 안전사고가 발생하는 문제점이 있었다.In addition, since the work method is not standardized, there is a problem that a safety accident occurs when the uninterruptible work and the attachment of the branch sleeve cover by removing the cover at any point.

따라서 이러한 상기 문제점을 해소하고자 안출된 등록특허 10-0823052에서는 상기 문제점을 해결하고 있으나, 여전히 특고압 전선을 가압하는 과정에서 밀폐링을 밀폐링홈에 맞춰 안착해야 하는 작업의 까다로운 문제점, 즉 대부분의 특고압 전선 작업시 작업 환경이 고소 작업 환경에서 이뤄지고 이러한 작업환경에서는 간단한 구성으로 가압 체결되는 구조가 아니면 대부분의 가압 체결에 있어 작업자에게 많은 불편을 제공하는 문제점이 있었다.Therefore, in order to solve the above problems, Patent Document 10-0823052 has been solved the above problems, but still difficult to solve the problem of the task of mounting the sealing ring to the sealing ring groove in the process of pressurizing the special high-voltage wire, that is, most of the special When the high-voltage wire work, the working environment is made in a high altitude working environment, and in this working environment, there is a problem that a lot of inconvenience is provided to the worker in most pressure tightening unless the structure is pressurized with a simple configuration.

또한, 상기 등록특허는 밀폐링이 밀폐링홈에 제대로 안착되어 있다 하더라도 특고압 전선을 가압하는 밀폐링의 가압력 조절을 이루지 못하여 특고압전선의 구경 굵기에 따른 적절한 가압력을 제공하기가 어렵고, 태풍 및 강풍이나 외부 요인에 의한 외력 발생시, 특고압전선의 피복 노출부가 절연커버틀에서 노출되어 특고압전선들의 마찰로 인한 합선 및 단전을 초래하는 문제점이 있었다.
In addition, even if the sealing ring is properly seated in the sealing ring groove, it is difficult to provide an appropriate pressing force according to the diameter of the extra-high voltage wire because it does not achieve the adjustment of the pressing force of the sealing ring pressurizing the extra-high pressure wire, typhoons and strong winds. However, when an external force is generated due to external factors, the exposed exposed portion of the extra high voltage wire is exposed from the insulating cover frame, which causes short circuit and power failure due to the friction of the extra high voltage wire.

도 1 내지 2에 도시된 바와 같이, 본 발명은 특고압 전선(80)을 포설하기 위한 절연커버구조를 구비함에 있어 반원으로 이루어지는 두 개의 절연커버(10)(20)를 구비하고, 상기 두 절연커버(10)(20)는 일측이 힌지부(40)로 구성되어 특고압 전선(80)을 포설할 경우 서로 회동하여 합치한 후 합치된 체결편(30)을 체결볼트(35)로 체결고정하여 특고압 전선(80)을 포설하게 된다.As shown in FIGS. 1 and 2, the present invention includes two insulating covers 10 and 20 made of a semicircle in the insulation cover structure for installing the extra-high voltage wires 80. Cover 10, 20 is one side is composed of the hinge portion 40, when installing the special high-voltage wire (80) is rotated and matched with each other after the mating fastening piece 30 is fastened by fastening bolts 35 To install the extra-high voltage wire (80).

즉 상기 두 절연커버(10)(20)는 일측 단부에 힌지부(40)를 구성하여 두 절연커버(10)(20)가 서로 연결된 상태를 이루게 되고, 두 절연커버(10)(20)의 각 타측 단부 전후 방으로는 체결편(30)을 형성한 상태를 이루게 됨으로써 두 절연커버(10)(20)를 회동하여 합치하게 되면 상기 체결편(30) 또한 합치를 이루게 되고 곧 체결편(30)을 체결볼트(35)로 체결하여 두 절연커버(10)(20)를 결합하게 되는 것이다.That is, the two insulating covers 10 and 20 form a hinge portion 40 at one end to form a state in which the two insulating covers 10 and 20 are connected to each other, and the two insulating covers 10 and 20 By forming the fastening piece 30 in the front and rear sides of each other end, when the two insulating covers 10 and 20 are rotated to coincide with each other, the fastening piece 30 also achieves a coincidence and soon the fastening piece 30 ) By fastening bolts 35 to combine the two insulating covers (10, 20).

이때 특고압 전선(80)은 체결 결합된 절연커버(10)(20)에 삽입된 상태를 이루게 된다.At this time, the extra-high voltage wire 80 is inserted into the insulation cover 10, 20 is fastened and coupled.

또한, 절연커버(10)(20) 외주연 전 후방에는 돌출체결부(50)가 형성되고 상기 돌출체결부(50)에는 레버(60)가 구비되는데 상세히 살펴보자면 도 3에 도시된 바와 같이, 돌출체결부(50)의 확장공(51)으로 레버(60)의 일부가 삽입된 상태를 이루게 되고 상기 레버(60)에는 나사봉(61)이 연속형성되어 확장공(51) 저면에 연속형성된 나사공(52)으로 레버(60)의 나사봉(61)이 삽입되는 구조이다.In addition, before the outer circumference of the insulating covers 10 and 20, a protrusion fastening portion 50 is formed, and the protrusion fastening portion 50 is provided with a lever 60, as shown in FIG. 3. A part of the lever 60 is inserted into the expansion hole 51 of the protruding fastening part 50, and a screw rod 61 is continuously formed in the lever 60 to continuously form the bottom of the expansion hole 51. It is a structure in which the screw rod 61 of the lever 60 is inserted into the screw hole 52.

상기 나사봉(61) 하부에는 걸림돌기(62)가 돌출되고 상기 걸림돌기(62)는 나사봉(61) 내부에 삽설된 스프링(63)과 연결되는 구조로 가압부(70)가 나사봉(61)과 연결될 경우에 가압부(70)의 결합공(71)으로 나사봉(61) 하부가 진입할 경우 걸림돌기(62)가 나사봉(61) 내부로 진입되고 상기 걸림돌기(62)의 진입으로 인하여 스프링(63) 또한 수축을 이루게 된다.A locking protrusion 62 protrudes below the screw rod 61, and the locking protrusion 62 is connected to a spring 63 inserted into the screw rod 61. When the lower portion of the screw rod 61 enters into the coupling hole 71 of the pressurizing part 70 when it is connected to the 61, the locking protrusion 62 enters into the screw rod 61 and the locking protrusion 62 Spring 63 also contracts due to the entry.

곧 가압부(70)의 결합공(71)으로 나사봉(61) 하부의 진입이 어느 정도 이뤄질 경우에는 상기 결합공(71) 내주연으로 형성된 걸림홈조(72)로 걸림돌기(62)가 탄발되는데 이는 수축된 상태의 스프링(63)이 신축되면서 스프링(63)의 탄성력에 의해 걸림돌기(62)가 탄발되어 걸림홈조(72)에서의 걸림이 이루어져 레버(60)의 회동에 의한 나사봉(61) 회동이 있을 경우 가압부(70)는 회동되지 않는 구조가 되는 것이다.When the entry of the lower portion of the screw rod 61 into the coupling hole 71 of the pressing portion 70 is made to some extent, the locking projection 62 is shot into the locking groove 72 formed by the inner circumference of the coupling hole 71. This is because the spring (63) in the contracted state is stretched, the locking projection 62 is elastic due to the elastic force of the spring (63) is caught in the locking groove (72) is made by the screw rod by the rotation of the lever 60 ( 61) When there is a rotation, the pressing unit 70 is a structure that is not rotated.

이로써 레버(60)의 회동에 의해 나사봉(61)이 나사공(52)을 진입하게 되면서 나사봉(61) 하부에 연결된 가압부(70)는 회동되지 않은 채 특고압 전선(80)을 점진적으로 가압하여 특고압 전선(80)의 탈리를 방지하고 피복 노출부(81)를 커버하게 되는 것이다.As a result, the screw rod 61 enters the screw hole 52 by the rotation of the lever 60, and the pressing part 70 connected to the lower portion of the screw rod 61 is gradually rotated without being rotated. By pressing to prevent the detachment of the extra-high voltage wire 80 and to cover the cover exposed portion 81.
