Description

이종 구조물의 계면 압력 측정 장치 및 그 방법Apparatus and method for measuring interfacial pressure of heterogeneous structures
본 발명은 이종 구조물의 계면 압력 측정 장치 및 그 방법에 관한 것으로, 더욱 상세하게는 금속 구조물의 일면에서부터 금속 구조물과 합성수지 구조물 사이의 접촉면까지 관통된 유로에 주입된 오일이 접촉면에서 분사되는 시점의 유로 내부 압력을 계면 압력으로 특정하여 취득하는 것을 특징으로 하는 이종 구조물의 계면 압력 측정 장치 및 그 방법에 관한 것이다.The present invention relates to an apparatus for measuring the interfacial pressure of heterogeneous structures and a method therefor, and more particularly, to a flow path at which oil injected into a flow path penetrating from one surface of a metal structure to a contact surface between a metal structure and a synthetic resin structure is sprayed from the contact surface. It relates to an apparatus and method for measuring the interfacial pressure of a heterogeneous structure, characterized in that the internal pressure is obtained by specifying the interfacial pressure.
종래에는 이종 구조물의 계면 압력을 측정하기 위해 이종 구조물 사이의 접촉면에 직접 센서를 부착하고, 센서 값을 측정하는 방법이 사용되었다.Conventionally, in order to measure the interfacial pressure of the heterogeneous structures, a method of directly attaching a sensor to the contact surface between the heterogeneous structures and measuring the sensor value has been used.
그러나 이러한 측정 방법은, 사용되는 센서의 제원(두께, 직경, 형태 등)이나 사양, 설치 과정에서 발생할 수 있는 다양한 변수에 의해 정확하고 정밀한 계면 압력을 측정하기 어려운 단점이 있었다.However, this measurement method has a disadvantage in that it is difficult to accurately and precisely measure the interfacial pressure due to various variables that may occur during the installation process, specifications (thickness, diameter, shape, etc.) or specifications of the sensor used.
또한, 센서를 포함하는 센싱 유닛을 계면 압력을 측정하고자 하는 부위를 따라 직접 이동 및 회전시키며 센싱하는 방법 및 장치가 사용되었다.In addition, a method and apparatus for sensing by moving and rotating a sensing unit including a sensor directly along a portion to be measured interface pressure were used.
그러나 이러한 측정 장치는, 구성이 복잡하고 체적이 클 뿐 아니라, 설치와 운용이 복잡한 단점이 있었다.However, such a measuring device has disadvantages in that the configuration is complicated and the volume is large, and the installation and operation are complicated.
이종 구조물 중에도 154kv 이상의 전압이 흐르는 초고압 케이블의 경우, 발열이나 누설 전류가 큰 사고로 연결될 수 있기 때문에, 정확하고 정밀한 계면 압력을 측정하여 생산 및 운용에 적용해야 한다.Even among heterogeneous structures, in the case of an ultra-high voltage cable with a voltage of 154kv or more, heat generation or leakage current may be connected to a large accident, so it is necessary to measure the interface pressure accurately and precisely and apply it to production and operation.
따라서, 구성이 간단하고 체적이 작으며, 설치 및 조작이 용이할 뿐 아니라, 설치 및 측정 시 변수가 적어 정확하고 정밀한 계면 압력의 측정이 가능한 장치 및 그 방법이 요구되는 실정이다.Accordingly, there is a need for an apparatus and method capable of accurately and precisely measuring interfacial pressure due to a simple configuration, small volume, easy installation and operation, and few variables during installation and measurement.

The internal pressure gradient (internal pressure of the flow path/oil injection time) of the flow path parts 31 and 21 is a positive value, and the internal pressure of the flow path parts 31 and 21 after the moment when the oil is injected to the contact surface S The slope (internal pressure of the flow passage/oil injection time) may be a negative value.
따라서, 본 발명에 따르면 유로부의 내부 압력이 상승하다 하락하는 순간(유로부의 내부 압력의 변화가 양의 값에서 음의 값이 되는 순간)을 정확히 캐치하고, 그 순간의 압력을 정확히 측정함으로써 정밀한 이종 구조물의 계면 압력을 취득할 수 있다. Therefore, according to the present invention, the moment when the internal pressure of the flow passage rises and falls (the moment when the change in the internal pressure of the flow passage changes from a positive value to a negative value) is accurately caught, and the pressure at that moment is accurately measured. The interfacial pressure of the structure can be obtained.
