휴대용 와이어 타입 열전대 부착장치{PORTABLE ATTACHMENT APPARATUS FOR WIRE TYPE THERMOCOUPLE}Portable Wire Type Thermocouple Attachment {PORTABLE ATTACHMENT APPARATUS FOR WIRE TYPE THERMOCOUPLE}

본 발명은 휴대용 와이어 타입 열전대 부착장치에 관한 것으로, 보다 상세하게는 휴대할 수 있어 모재의 크기나 위치에 상관없이 간편 용이하게 측정부위의 온도를 측온할 수 있도록 한 배터리 충전방식의 용접기능을 갖는 휴대용 와이어 타입 열전대 부착장치에 관한 것이다.The present invention relates to a portable wire type thermocouple attachment device, which can be carried in more detail, and has a welding function of a battery charging method to easily measure the temperature of the measurement site regardless of the size or position of the base material. A portable wire type thermocouple attachment device.

일반적으로, 열전대(Thermocouple)는 구조적으로 간단하고 조작이 용이하여 산업현장이나 실험실 등에서 많이 쓰이는 전기 신호식 온도계이다.In general, a thermocouple is an electrical signaling thermometer that is widely used in industrial sites and laboratories due to its simple structure and easy operation.

특히, 이러한 열전대는 측정값이 전기적 신호인 전압 크기로 출력되기 때문에 먼 거리까지 전송할 수 있어 중앙제어에 유용하게 활용되고 있다.In particular, these thermocouples are useful for central control because they can be transmitted over long distances because the measured values are output as voltages, which are electrical signals.

이와 같은 열전대에서의 온도 측정은 두 개의 다른 금속선의 양단에 접점을 만들고, 그들중 일단인 '측온접점'에 열을 가하면 타단인 '기준접점'과의 온도 차이만큼 회로내에서 전압이 발생되는 원리를 이용하여 이루어진다.In this thermocouple, the temperature measurement is made by making contacts at both ends of two different metal wires, and when one of them is heated to the 'temperature contact', the voltage is generated in the circuit by the temperature difference from the other reference point. Is done using.

그러나, 발전설비 보일러 수관벽 파이프나 혹은 산업설비의 배관 및 탱크 등과 같은 특정부위의 온도측정을 위해서는 열전대, 특히 와이어 타입 열전대를 부착 할 때에 용접기를 피측정물 근처까지 이동시킨 후 용접기의 접지전극을 피측정물에 접지한 다음 열전대를 용접하여 부착해야 하는 불편함이 존재하게 된다.However, in order to measure the temperature of a specific part such as a water pipe of a power plant, a boiler water pipe, or a pipe and a tank of an industrial facility, when the thermocouple, especially a wire type thermocouple, is attached, the welding machine is moved near the object to be measured, and then the ground electrode of the welder is moved. There is an inconvenience in that the thermocouple must be welded and attached after being grounded to the object under test.

뿐만 아니라, 용접기는 부대설비들이 많아 크기가 커 이동이 용이하지 않기 때문에 용량이 큰 탱크나 파이프의 경우 온도측정 작업이 상당히 위험하다는 단점도 있었다.In addition, the welding machine has a disadvantage that the temperature measurement work is quite dangerous in the case of a large capacity tank or pipe because the welding equipment has a large number of auxiliary equipment is not easy to move.

아울러, 열전대는 탱크나 파이프류 등의 발전설비를 생산하는 과정중에도 열처리 공정에서 많이 사용되게 되는데 대량으로 열처리할 경우 그때마다 열전대를 부착하고 떼는 일을 지속적으로 반복해야 하는 불편과, 이로 인한 작업효율의 급격한 저하는 공정차질을 불러와 생산성 하락의 주된 요인으로 자리 잡고 있기도 하다.In addition, thermocouples are frequently used in the heat treatment process during the production of power generation equipment such as tanks and pipes. In case of heat treatment in large quantities, the inconvenience of having to repeatedly attach and detach the thermocouple every time, and the work efficiency The sharp decline in the market is leading to process disruption, which is the main reason for the decline in productivity.
