본 발명은 계기용 변성기(MOF)의 단자커버를 봉인하는 것에 관한 것으로, 더 상세하게는 특별 고압이 통전되는 계기용 변성기의 특성상 점검자가 근접할 수 없는 상태에서 그 계기용 변성기의 단자커버 봉인 여부를 원거리에서도 용이하게 확인할 수 있도록 한 계기용 변성기의 단자커버용 봉인장치 및 그 제조방법에 관한 것이다. The present invention relates to sealing the terminal cover of the instrument transformer (MOF), and more specifically, whether or not the terminal cover of the instrument transformer is sealed in the state that the inspector can not approach due to the characteristics of the instrument transformer for which a special high voltage is energized. The present invention relates to a sealing device for a terminal cover of an instrument transformer so that it can be easily confirmed from a long distance, and a manufacturing method thereof.

일반적으로 계기용 변성기(MOF)는 특별 고압이 통전, 즉 고전압회로의 전압전류를 사용량에 비례 저전압 소전류로 변환하여 사용 전력계에 측정값을 전달하는 것으로, 이는 송/배선 선로 및 기타 전력 계통의 구성요소를 감시하는 계전기 또는 계측기 등의 계기와 조합을 이루도록 사용된다. In general, the transformer for transformer (MOF) transmits the measured value to the power meter by converting the voltage current of high voltage circuit into low voltage and small current proportional to the usage, which is used in transmission / wiring lines and other power systems. It is used in combination with instruments such as relays or instruments that monitor components.

상기와 같이 사용되는 계기용 변성기는 설치시 단자함에서 배선을 완료한 후, 그 단자함에 단자커버를 체결볼트로 고정한 다음 상기 단자함의 내부조작을 방지하고자 봉인장치를 사용하여 봉인하였다. The transformer for the instrument used as described above, after completing the wiring in the terminal box at the time of installation, the terminal cover was fixed with a fastening bolt and then sealed using a sealing device to prevent the internal operation of the terminal box.

이러한 계기용 변성기의 단자커버를 봉인하는 종래의 봉인장치(100)는 도 5에 도시된 바와 같이 납으로 된 원통형 몸체(110)의 구멍에 와이어(120)를 통과시키고 다시 계기용 변성기의 단자함과 단자커버에 형성되는 봉합홀을 통과시킨 다음, 와이어를 묶은 상태에서 봉인공구를 사용하여 상기 원통형 몸체(110)를 압착시키는 바, 그 몸체를 압착시에는 봉인장치의 진위 여부를 판별할 수 있도록 봉인공구의 압인 무늬를 납으로 된 원통형 몸체에 압입하여 형성하거나 별도의 일련번호 등을 표시하였다. The conventional sealing device 100 for sealing the terminal cover of the instrument transformer is passed through the wire 120 through the hole of the cylindrical body 110 made of lead, as shown in Figure 5 and again the terminal box of the instrument transformer Pass the sealing hole formed in the terminal cover, and then press the cylindrical body 110 using a sealing tool in the state of tying the wire, when the body is crimped to seal the authenticity of the sealing device The stamped pattern of the tool was formed by press-fitting into a cylindrical body made of lead or indicated with a separate serial number.

그러나, 상기한 종래의 봉인장치는 별도로 봉인공구를 휴대하고 다녀야 하는 불편함이 있고 몸체가 납으로 되어 있어 납중독을 일으킬 수 있는 위험성이 있을 뿐만 아니라 납으로 인한 피부병의 원인이 되고 몸체의 구멍에 와이어를 통과시키는 작업이 어려워 봉인작업의 효율이 떨어지는 문제점이 있었다. However, the conventional sealing device has the inconvenience of carrying a separate sealing tool, and the body is made of lead, there is a risk of lead lead poisoning, as well as the cause of skin diseases caused by lead and wire in the hole of the body It was difficult to pass the work there was a problem that the efficiency of the sealing work falls.
