Description

소선절연도체의 에나멜피막 제거장치{Device for peeling the enamelled coating layer of conductor}Device for peeling the enamelled coating layer of conductor

본 발명은 초고압케이블을 구성하는 소선절연도체에 관한 것으로, 특히 소선절연도체의 피막제거에 따른 작업효율을 향상시킬 수 있도록 한 소선절연도체의 에나멜피막 제거장치에 관한 것이다.The present invention relates to a wire insulated conductor constituting an ultra-high voltage cable, and more particularly, to a device for removing an enamel encapsulated wire of a wire insulated conductor to improve the work efficiency according to the removal of the wire of the wire insulated conductor.

일반적으로, 소선절연케이블은 일반 초고압케이블과 달리 소선(초고압케이블을 구성하는 얇은 선)을 에나멜코팅 방식으로 절연하여 구성한 케이블의 한 종류로서, 이 소선절연케이블은 소선들간 열전도현상을 차단해 표피효과에 따른 도체저항을 감소시켜 송전용량을 향상하게 된다.In general, the wire insulated cable is a type of cable insulated from the wires (thin wires constituting the ultra high voltage cable) by enamel coating, unlike the general high voltage cable. By reducing the conductor resistance according to the improved transmission capacity.

따라서, 상기 소선절연케이블의 소선절연도체를 슬리브 압축 접속하려는 경우, 상기 소선절연도체의 말단부에 절연된 상기 절연피막을 제거하여 소선도체들을 접속시키는 과정이 선결되어야 하므로, 상기 소선절연도체의 절연피막을 제거하기 위한 많은 제거장치들이 개발중에 있다. Therefore, in the case of sleeve compression connection of the wire insulated conductor of the wire insulated cable, the process of connecting the wire conductors by removing the insulating film insulated at the distal end of the wire insulated conductor should be made in advance. Many removal devices are under development to eliminate this problem.

예컨대, 상기 소선절연도체의 절연피막을 제거하는 방법으로는 샌드블라스팅법과 같은 기계적인 방법이 제안된 바 있으나, 이 기계적인 방법들은 작업시간이 길어 효율성이 저하될 뿐만 아니라 상기 절연피막의 균일한 제거작업이 이루어지지 않아 품질이 저하되는 문제점이 있었다. For example, as a method of removing the insulating coating of the wire insulator, a mechanical method such as sandblasting has been proposed, but these mechanical methods not only reduce efficiency due to long working time but also uniform removal of the insulating coating. There was a problem that the quality is reduced because the operation is not made.

그리고, 상기 소선절연도체의 절연피막을 제거하는 방법으로서 상기 말단부를 용접조에 담그고 피막의 제거와 동시에 용접 도금하는 물리화학적인 방법이 제안된 바 있으나, 이 방법들은 상기 도금과정에서 가요성을 저해시키는 단점이 있어 사용이 제한되는 문제점이 있었다.As a method of removing the insulation coating of the wire insulator, a physicochemical method of dipping the end portion in a welding bath and welding plating at the same time as the removal of the coating has been proposed, but these methods are used to inhibit the flexibility in the plating process. There was a problem in that the use is limited.

그리고, 상기 소선절연도체의 절연피막을 제거하는 또다른 방법으로서 약액에 침지하는 방법이 제안된 바 있으나, 이 화학적 방법들도 역시 상기 피막제거의 작업시간이 길어질 뿐만 아니라 상기 약액의 기화에 의한 가스가 발생하여 작업환경을 악화시키는 문제점이 있었다.As another method of removing the insulation coating of the elementary insulator, a method of immersing it in a chemical solution has been proposed, but these chemical methods also increase the working time of removing the coating, as well as gas by vaporization of the chemical solution. There was a problem that aggravates the working environment.

이에, 본 발명은 상기한 바와 같은 문제점을 해결하기 위하여 안출된 것으로, 소선절연도체의 말단부에 절연된 에나멜피막의 제거에 따른 작업시간 및 작업하중을 절감하여 각종 부대비용을 절감시킬 수 있도록 한 소선절연도체의 에나멜피막 제거장치를 제공하는 데에 그 목적이 있다. Accordingly, the present invention has been made to solve the problems described above, the wire to reduce the work time and work load caused by the removal of the enamel coating insulated at the distal end of the wire insulation conductor It is an object to provide an enamel coating removal device for an insulated conductor.

First, the film removing apparatus 1 pumps the organic solvent supplied to the film removing chamber 20 to the pump pump 31 to increase the contact area and to heat the solvent using the solvent heater 40. By doing so, the work time and the work load for removing the enamel coating coated on the distal end 11 are minimized.

The film removing chamber 20 not only forms the outer appearance of the film removing apparatus 1 but also supports the total load of the device, and the distal end portion 11 of the wire insulated conductor 10 is fitted at one side thereof. As the coupler 21 is formed, an accommodation space 22 having a predetermined size to accommodate the organic solvent is formed therein.

또한, 상기 결합구(21)에 상기 소선절연도체(10)내로 유기용제가 침투하는 것을 방지하는 원통형상의 히팅밴드(23)를 장착함이 바람직하다.In addition, the coupling sphere 21 is preferably equipped with a cylindrical heating band 23 to prevent the organic solvent penetrates into the elementary insulated conductor (10).

이때, 상기 유기용제는 상기 말단부(11)에 분사되는 것으로서, 그 소재로는 NMP(N-methyl-2-pyrrolidone)가 바람직하다.At this time, the organic solvent is sprayed on the end portion 11, the material is preferably NMP (N-methyl-2-pyrrolidone).

그리고, 상기 용제공급기(30)는, 상기 수용공간(22)에 상기 유기용제를 공급하는 것으로서,상기 피막제거실(20)내의 용제가열기(40)에 의해 가열된 용제탱크(24)를 연결하는 공급관로(33), 및 상기 공급관로(33)의 선단부에 장착되어 상기 수용공간(22)내로 상기 유기용제를 분사하는 분사노즐(32)로 구성된다.The solvent supplier 30 supplies the organic solvent to the accommodation space 22, and connects the solvent tank 24 heated by the solvent heater 40 in the film removal chamber 20. It is composed of a supply pipe 33, and the injection nozzle 32 is attached to the front end of the supply pipe 33 for injecting the organic solvent into the receiving space (22).

이때, 상기 분사노즐(32)은 상기 말단부(11)와 유기용제의 접촉면적을 고려하여 다수개 장착함이 바람직하다. At this time, the injection nozzle 32 is preferably mounted in plurality in consideration of the contact area between the distal end 11 and the organic solvent.

또한, 상기 공급관로(33)의 관로에는 상기 유기용제를 지속적으로 상기 말단부(11)를 향해 압송하는 압송펌프(31)가 장착된다. In addition, the pipeline of the supply pipe 33 is equipped with a pressure feed pump 31 for continuously feeding the organic solvent toward the distal end portion (11).

In addition, the film removing apparatus 1 is set to a temperature range of 50 ~ 150 ℃ of the film removing chamber 20 as well as the operating time of the pressure pump 31 is set to 5 to 30 minutes to the film Removal is performed.

이렇게 하면, 상기 용제공급기(30)의 분사노즐(32)을 통해 압송되는 상기 유기용제가 상기 용제가열기(40)에 의해 활성화된 상태에서 상기 말단부(11)로 분사되어 접촉면적이 최대화되는 것이다.In this case, the organic solvent that is pumped through the injection nozzle 32 of the solvent supplier 30 is sprayed to the distal end 11 in the state activated by the solvent heater 40 to maximize the contact area. .
