Description

상온 수축형 프리몰드형 접속함 조립법 {Cold shrinkable assembly method for premold cable joint}Cold shrinkable assembly method for premold cable joint

본 발명은 초고압 XLPE 케이블용 프리몰드형 접속함에 관한 것으로서, 보다 상세하게는 프리몰드형 접속함을 자기 탄성력을 이용하여 공장에서 미리 확관 시킨 후 현장에서 간다히 조립하는 방법에 관한것이다.The present invention relates to a pre-molded junction box for an ultra-high pressure XLPE cable, and more particularly, to a method of assembling the pre-molded junction box in advance in the factory using a magnetic elastic force and then assembled in the field.

일반적으로 프리몰드형 접속함의 확관을 유지할 수 있는 시간은 탈취의 용이성을 고려하여 4시간에서 8시간 내외로 제한하고 있다.In general, the time to maintain the expansion of the pre-molded junction box is limited to about 4 to 8 hours in consideration of ease of deodorization.

이때문에 공장에서 미리 확관하여 현장에서 수축시켜 시공하는 것은 고전압용 프리몰드 접속함에는 불가능 하여 대부분의 경우에 시공 현장에서 케이블 위로 확관하여 조립하고 있다.For this reason, it is impossible to expand the factory in advance and shrink and install it in the field. Therefore, in most cases, it is assembled on the cable at the construction site.

종래의 초고압 XLPE 케이블용 프리몰드형 접속함은 공장에서 미리 성형된 후 시공 현장에서 확관, 케이블에 삽입한 후 다시 탈취하는 방법을 사용하거나 케이블에 직접 확관하여 삽입하는 방법으로 시공해 왔다.Conventional high-mould XLPE cable pre-molded junction box has been constructed by using a method of pre-molded at the factory and then expanded in the construction site, inserted into the cable and then again deodorized or directly inserted into the cable.

이와 같이 현장에서 시공 할 경우 접속 공사에 소요되는 인력 및 장비의 증가로 시공비의 증가가 불가피하며 또한 작업시간이 지연된다.In the case of construction in this way, the increase of construction cost is inevitable due to the increase of manpower and equipment required for the connection work, and also delays the working time.

본 발명의 상온 수축형 프리몰드형 접속함 조립방법은 이상에서 설명한 종래의 문제점을 해소하기 위한 것으로서, 프리몰드형 접속함을 공장에서 확관하거나 또는 현장에서 직접 시공할 수 있도록 공장에서 코어 와이어 위에 미리 확관된 프리몰드형 접속함을 현장에서 코어 와이어를 양쪽으로 풀어주기만 하면 작업이 완료될 수 있도록하여 케이블 접속 공사 시간을 단축하고, 장비 및 소요되는 인력을 줄이게 되어 시공비를 절감할 수 있는 상온 수축형 프리몰드형 접속함 조립방법을 제공하는데 그 목적이 있다.The method for assembling a room temperature shrinkage type pre-mold junction box of the present invention is to solve the conventional problems described above, and is pre-expanded on the core wire at the factory so that the pre-mold junction box can be expanded in a factory or directly on site. The pre-mold connection box can be completed by simply releasing the core wires on both sides of the site, so that the work can be completed, reducing the time for cable connection construction, and reducing the construction cost by reducing the equipment and manpower required. The purpose is to provide a method of assembling the ship.

상기에서 설명한 본 발명의 목적을 달성하기 위하여, 나선형 탭을 가공한 확관 파이프와, 나선형 탭에 감겨 슬리브를 확관하는 금속 혹은 고분자로 제작한 코어 와이어 슬리브와, 나선형 탭에 감긴 코어 와이어를 프리몰드 접속함 슬리브 내부로 삽입할 수 있도록 하는 압축장치를 사용한 상온 수축형 프리몰드형 접속함 조립방법이다.In order to achieve the object of the present invention described above, a pre-mold connection is made of an expansion pipe processed by a spiral tab, a core wire sleeve made of a metal or a polymer wound on the spiral tab to expand the sleeve, and a core wire wound on the spiral tab. A method for assembling a cold shrinkable pre-molded junction box using a compression device that can be inserted into a box sleeve.

이하 첨부된 본 발명의 도면을 참조하여 상세히 설명하면 다음과 같다.Hereinafter, described in detail with reference to the accompanying drawings of the present invention.

도 1은 본 발명의 확관 파이프에 코어 와이어가 감긴 상태를 도시한 것이고, 도 2는 본 발명의 슬리브를 확관 하기전의 구조도이며, 도 3은 본 발명의 확관 작업 후의 작업도 이다.1 shows a state in which a core wire is wound around an expansion pipe of the present invention, FIG. 2 is a structural diagram before expansion of a sleeve of the present invention, and FIG. 3 is an operation diagram after an expansion operation of the present invention.

여기서 부호 10은 확관 파이프로서, 이 확관 파이프는 외주연에 나선형 탭(11)을 형성한다. 이 나선형 탭(11)은 앞부분과 뒷부분 2단으로 형성한다.Reference numeral 10 is an expansion pipe, which forms a spiral tab 11 on the outer circumference. The spiral tab 11 is formed in two stages, the front part and the rear part.

그리고 이 확관 파이프(10)의 일측에는 어댑터(30)를 부착할 수 있도록하며, 나선형 탭(11)에는 코어 와이어(20)를 나선형에 맞추어 감을수 있는 것으로 확관 작업후 앞부분과 뒷부분의 나선형 탭(11)에 각각 분리된 코어 와이어(20)를 감는다.And one side of the expansion pipe 10 to be able to attach the adapter 30, the spiral tab 11 to the core wire 20 can be wound in a spiral to the spiral tab of the front and rear part after expansion work ( 11) wound the core wires 20, each separated.

이후 상기 확관 파이프(10)의 선단에는 프리몰드 접속함 슬리브(40)에 코어 와이어(20)를 쉽게 삽입할 수 있도록 아댑터(30)를 장착한다.After that, the adapter 30 is mounted on the tip of the expansion pipe 10 so that the core wire 20 can be easily inserted into the pre-molded junction box 40.

이상과 같이 확관 파이프(10)에 아댑터(30)를 장착한 후에는 확관 파이프(10)를 압축장치(50)에 삽입 고정하고, 이후 프리몰드 접속함 슬리브(40)를 압축장치(50)에 삽입하며, 이 프리몰드 접속함 슬리브(40)는 슬리브 고정치구(51)에 고정한다. 확관 작업 이후에는 아댑터(30)를 분리하고 코어 와이어(20)와 확관 파이프(10)를 돌려서 분리한다. 이후 현장에서 케이블에 접속될 위치에 자리 잡은 후 코어 와이어(20)를 안쪽에서 부터 양쪽으로 풀어 나가면 케이블 접속 작업이 완료되는 것으로 상기 코어 와이어(20)는 확관 파이프(10)를 제거한 후에도 프리몰드 접속함 슬리브(40)의 수축 압력을 견딜수 있는 금속 혹은 고분자로 제작한다.After the adapter 30 is mounted on the expansion pipe 10 as described above, the expansion pipe 10 is inserted into and fixed to the compression device 50, and then the premold junction box sleeve 40 is attached to the compression device 50. The premold junction box sleeve 40 is inserted into the sleeve fixture 51. After expansion work, the adapter 30 is removed and the core wire 20 and the expansion pipe 10 are rotated to be separated. Thereafter, when the position is to be connected to the cable in the field and the core wire 20 is released from both sides from the inside, the cable connection work is completed. The core wire 20 is pre-molded even after the expansion pipe 10 is removed. It is made of a metal or polymer that can withstand the shrinkage pressure of the box sleeve (40).

이상에서 상세히 설명한 바와같이 본 발명은 공장에서 코어 와이어와 확관 파이프를 이용 미리 확관한 프리몰드형 접속함을 현장에서 코어 와이어를 양쪽으로 풀어주기만 하면 작업이 완료되어 케이블 접속 작업 시간을 단축할 수 있고, 또한 인력 및 장비의 감소로 시공비를 줄일수 있다.As described in detail above, the present invention can be completed by simply releasing the core wire on both sides of the pre-molded junction box which is pre-expanded using the core wire and the expansion pipe in the factory, and thus shortening the cable connection work time. In addition, construction costs can be reduced by reducing manpower and equipment.
