Description

영상변류기의 제조방법Manufacturing Method of Image Current Transformer

본 발명은 영상변류기(Zero-close Current Transformer)를 제조하는 방법에 관한 것으로, 더욱 상세하게는 일정 길이의 핀을 사용하여 핀컷팅작업의 생략으로 정확한 칫수와 자동삽입가능하고 딥핑으로 코일소손의 방지와 작업시간의 개선과 공정자동화를 도모할 수 있는 영상변류기의 제조방법에 관한 것이다.The present invention relates to a method for manufacturing a zero-close current transformer, and more particularly, by using a pin of a certain length to eliminate the pin cutting operation, accurate dimensions and automatic insertion possible, and prevents coil burnout by dipping. The present invention relates to a method of manufacturing a current transformer that can improve work time and process automation.

일반적으로 변압기는 2개이상의 권선과 공통의 자로(磁路)로 이루어지고, 자기유도작용에 의해 1차의 권선에 받았던 교류전력을 2차의 권선에 전달하는 정지유도기(Stationary Induction Apparatus)인 바, 이는 권선과 자로의 배치에 의해 내철형과 내철형으로 구별된다.In general, a transformer is a stationary induction apparatus that consists of two or more windings and a common magnetic path, and transfers the AC power received by the primary winding to the secondary winding by magnetic induction. , It is distinguished into the inner type and the inner type by the arrangement of the winding and the magnetic path.

그리고, 계기용 변성기(Instrument Transformer)는 전압이나 전류를 측정, 제어하는 것에 편리한 값으로 변성하기 위해 사용되는 것이다.Instrument transformers are used to transform voltages and currents to values that are convenient for measuring and controlling current.

상기 계기용 변성기를 대별하면 전류를 변성하는 변류기와 전압을 변성하는 계기용 변압기로 나누어진다.The instrument transformer is divided into a current transformer for modifying current and an instrument transformer for modifying voltage.

한편, 전기선로상에서 설치되어 작동되는 산업용 누전차단기의 한부분품으로 사용되는 영상변류기는 내부의 콘트롤러인 전자회로기판에 부착되어, 선로누전시 이를 영상변류기에서 언바란스를 감지하여 트립디바이스의 구동, 즉 트립코일이 자력화되어 온된 손잡이노브를 자동으로 오프시키도록 되어 있다.On the other hand, the video current transformer used as a part of the industrial earth leakage breaker installed on the electric line is attached to the electronic circuit board which is an internal controller. The coil is adapted to automatically turn off the magnetized knob.

이상과 같이 작동되는 영상변류기는 도 3와 같으 제조공정으로 완성시켜 산업용 누전차단기에 설치하게 된다.The video current transformer operated as described above is completed in the manufacturing process as shown in FIG. 3 and installed in the industrial earth leakage breaker.

먼저, 도 3(A)는 코일 솔더링(Coil Soldering)공정으로서 코일(10)을 2개의 핀(11)에 감은 다음 솔더링하게 되고, 이 솔더링은 작업자가 전기인두 등을 사용하기 때문에 상기 코일(10)의 소손우려와 핀(11)을 손으로 잡고 하기 때문에 뜨거워져 힘이 들고 작업시간이 많이 소요된다는 결점이 발생되었다.First, FIG. 3 (A) is a coil soldering process, in which a coil 10 is wound around two pins 11 and then soldered. This soldering is performed by an operator using an electric iron. ), And the pin (11) by holding the hand by hand because it is hot and the drawback of the power takes a lot of time.

도 3(B)는 코일(10)과 2개의 핀(11)이 솔더링된 상태를 케이스(13)에 조립하는 공정으로서, 상기 상태를 케이스(13)의 중앙기둥(14)에 결합하고 핀(11)의 솔더링부분을 호울(15)에 압입하고, 이때 핀(11)을 압입할 때 코일(10)이 단선될 우려가 있다.3 (B) is a process of assembling a state in which the coil 10 and two pins 11 are soldered to the case 13, which is coupled to the central column 14 of the case 13 and the pin ( When the soldering part 11 is pressed into the hole 15, the coil 10 may be disconnected when the pin 11 is pressed in.

따라서, 영상변류기의 최종 공정인 모울딩공정은 도 3(B)와 같이 결합된 상태에서 에폭시(16)를 주입하여 도 3(C)와 같이 완성되는 바, 주입시 핀(11)에 붙는 현상, 표면장력으로 인하여 핀(11)에 올라 붙고 레벨오버(Level Over)로 전자회로기판의 부착면이 평면이 되지 않아 밀착불량의 발생이 심각하다는 결점이 있었다.Therefore, the molding process, which is the final process of the image current transformer, is completed as shown in FIG. 3 (C) by injecting epoxy 16 in a bonded state as shown in FIG. 3 (B). On the other hand, due to the surface tension, the pin 11 is attached to the pin 11 and the surface of the electronic circuit board is not flat due to the level over (Level Over).

본 발명은 상기와 같이 종래 영상변류기의 제조방법이 가지고 있는 문제점들을 해소하기 위해 안출한 것으로, 종래와 달리 간단한 자동검사 및 모울딩뿐만 아니라 대량생산에 따른 제조의 자동화가 이루어지고, 또 일정 길이의 핀을 사용하여 핀컷팅작업의 생략으로 정확한 칫수와 자동삽입가능하고 딥핑으로 코일소손의 방지와 작업시간의 개선, 그리고 평탄한 케이스면에 핀이 인출되어 전자회로 기판의 부착면이 현저히 개선됨을 기할 수 있는 영상변류기를 제조하는 방법을 제공함에 그 목적이 있다.The present invention has been made to solve the problems of the conventional method of manufacturing a current transformer as described above, unlike the prior art simple automatic inspection and molding as well as the automation of the manufacturing according to the mass production, and a certain length The use of pins eliminates pin-cutting work, allowing accurate dimensions and automatic insertion, and dipping prevents coil burnout, improves working time, and withdraws pins on a flat case surface, significantly improving the attachment surface of the electronic circuit board. It is an object of the present invention to provide a method for manufacturing a current transformer.
