Description

배전선로용 불량 폴리머 애자 검출장비{Apparatus detecting energized insulator polymer for distribution line}Apparatus detecting energized insulator polymer for distribution line

본 발명은 배전선로용 불량 폴리머 애자 검출장비에 관한 것으로, 더욱 상세하게는 폴리머 애자의 불량여부를 검출하여 열화 등과 같은 선로사고를 사전에 방지할 수 있음은 물론 불량 폴리머 애자의 검출작업을 진행하는 전신주 위치를 측정하여 검출작업의 정확성을 확보할 수 있도록 하는 배전선로용 불량 폴리머 애자 검출장비에 관한 것이다.
The present invention relates to a bad polymer insulator detection device for a distribution line, and more specifically, to detect whether or not the polymer insulator defects in advance to prevent line accidents such as deterioration, as well as to detect the bad polymer insulator The present invention relates to a poor polymer insulator detection device for a distribution line that measures the position of the telephone pole to ensure the accuracy of the detection operation.

일반적으로 불량 애자 검출장비는 애자의 절연상태를 확인하여 불량 애자의 검출작업을 시행하기 위해서 사용된다.In general, the defective insulator detection equipment is used to check the insulation state of the insulator and perform the detection operation of the insulator.

본 발명의 배경기술은 본 출원인이 등록권리자인 대한민국 등록특허공보 제10-0892679호(2009.04.15)에 개시되어 있다.Background art of the present invention is disclosed in Republic of Korea Patent Publication No. 10-0892679 (2009.04.15) the applicant is a registered right holder.

그러나 종래의 불량 애자 검출장비는 검출작업 중인 애자와 주변환경을 함께 촬영하여 측정된 애자의 전압수치와 촬영된 이미지를 자료화하여 불량 애자의 검출작업에 대한 시각적인 검증 및 신뢰성을 확보할 수 있으나, 이는 폴리머 애자의 경우 일체형(단일형)으로 되어 있어 중간 부분의 불량을 정확하게 검출할 수 없는 기능상의 한계를 갖게 되었다.However, the conventional defective insulator can secure the visual verification and reliability of the detection of the defective insulator by recording the measured insulator voltage and the surrounding environment together with the measured voltage value of the insulator and the photographed image. In the case of the polymer insulator, it has a unitary (single) type and has a functional limitation in that failure of the middle portion cannot be accurately detected.

즉, 종래에는 폴리머 애자의 양측에 대한 전위차를 측정 및 비교하여 불량 애자를 검출하고 있으나, 이는 자기 애자와 달리 폴리머 애자의 특성상 절연구간이 일체로 이루어진 상태이므로 폴리머 애자의 중간 일부분이 불량이더라도 전위차의 변화가 발생하지 않으므로 불량 폴리머 애자를 정확하게 검출할 수 없는 문제점을 갖게 되었다.That is, conventionally, the defective insulator is detected by measuring and comparing the potential difference between both sides of the polymer insulator, but unlike the magnetic insulator, since the insulation section is integrally formed due to the characteristics of the polymer insulator, even if the middle part of the polymer insulator is defective, Since no change occurs, a problem arises in that the defective polymer insulator cannot be accurately detected.

특히 폴리머 애자의 불량을 정확하게 검출하지 못할 경우에는 열화 등과 같은 선로사고가 발생하는 문제점을 갖게 되었다.In particular, when the defect of the polymer insulator is not accurately detected, a line accident such as deterioration occurs.

아울러 종래에는 검출작업 중인 애자의 정확한 전신주 위치(지리적 위치)를 측정할 수 없으므로 불량 애자의 검출작업의 정확성을 확보할 수 없는 문제점을 갖게 되었다.
In addition, since the conventional telephone pole position (geographic position) of the insulator in the detection operation cannot be measured, there is a problem that the accuracy of the detection operation of the insulator can not be secured.
