Abstract

PURPOSE: An electric test apparatus of a rubber sleeve is provided to reduce a test time by testing two rubber sleeves, simultaneously. CONSTITUTION: A cable semiconducting layer(30) is connected between the first and the second rubber sleeves(10). The cable semiconducting layer(30) and the cable insulating layer(20) are connected with a cable of 2M. A corona shield(40) is adhered to an end portion of a high voltage cable in order to prevent corona generated from an inside of an insulator. The cable is inserted into the first rubber sleeve(10) after a lubricating oil is applied on the cable and the first rubber sleeve(10). The second rubber sleeve(10) is inserted into a predetermined position. Tests for the first and the second rubber sleeves(10) is performed simultaneously.

일반적으로 초고압 프리몰드형 접속함의 종단 접속함에는 고무 슬리브가 사용되는데, 상기 고무 슬리브는 초고압에 강한 제품을 사용하여야 하는 관계로 전기적인 시험을 시행하게 된다.In general, a rubber sleeve is used as a termination box of an ultra-high pressure pre-molded junction box, and the rubber sleeve is subjected to an electrical test because a product that is resistant to ultra high pressure should be used.

그러나, 종래의 종단 접속함에 이용되는 고무 슬리브의 전기적 시험은 1개씩만 시험이 가능하여 작업 시간이 많이 소요되는 한편, 실제 케이블을 사용하여 고무 슬리브에 대한 전기적 시험을 시행하지 않는 관계로 실제로 사용될때에는 많은 하자가 발생되는 문제점을 가졌다.However, the electrical test of the rubber sleeve used in the conventional termination box can be tested only one by one, which takes a lot of work time, and when it is actually used because it does not perform the electrical test on the rubber sleeve using an actual cable. Many defects have occurred.

본 발명은 상술한 문제점을 해결하기 위하여, 본 발명은, 2개의 종단의 고무 슬리브를 동시에 시험이 가능하도록 하여 시험 시간을 단축시키는 한편, 실제 케이블을 사용하여 실제 사용 조건을 모의 시험하여 실제 시험 전압 인가시 인가되는 전계를 기준으로 인가 전계 이상의 값을 가지도록 설계된 초고압 종단 접속함용 고무 슬리브의 전기적 시험 장치를 제공하는 것을 그 목적으로 한다.In order to solve the above-mentioned problems, the present invention reduces the test time by allowing the rubber sleeves of two ends to be tested at the same time, while simulating the actual conditions of use using a real cable to test the actual test voltage. It is an object of the present invention to provide an electrical test apparatus for a rubber sleeve for an ultra high voltage end junction box designed to have a value greater than or equal to an applied electric field based on an electric field applied when applied.

도 1은 본 발명의 초고압 종단 접속함용 고무 슬리브의 전기적 시험 장치에 관한 단면도로서, 종단 접속용 고무 슬리브(10)에 케이블 절연층(20)이 삽입되고, 고압 케이블의 단부에는 코로나를 방지하기 위한 코로나 쉴드(40)가 부착되어 있다. 또한, 종단 접속용 고무 슬리브(10)의 사이에는 케이블 반도전층(30)이 연결되어 있음을 도시하고 있다.1 is a cross-sectional view of an electrical test apparatus for a rubber sleeve for an ultra-high voltage termination junction box of the present invention, in which a cable insulation layer 20 is inserted into a rubber sleeve 10 for termination, and at the end of the high-voltage cable to prevent corona. The corona shield 40 is attached. In addition, it is shown that the cable semiconducting layer 30 is connected between the rubber sleeve 10 for the termination.

상술한 설명과 같이, 본 발명의 고무 슬리브(10)에 대한 적용 순서를 살펴보면, 약 2M 정도의 케이블을 준비하여 케이블에 케이블 반도전층(30) 및 케이블 절연층(20)을 연결 설치하고 준비된 케이블의 단부에는 코로나 쉴드(Corona shield)(40)를 장착하여 시험 절연물 내부에서 발생하는 코로나의 발생이 억제되도록 한다.As described above, looking at the application sequence for the rubber sleeve 10 of the present invention, by preparing a cable of about 2M to connect the cable semiconducting layer 30 and the cable insulation layer 20 to the cable and installed the prepared cable Corona shields 40 are fitted at the ends of the corona shields to prevent the occurrence of coronas inside the test insulator.

윤활유를 케이블 및 슬리브에 바른 후 종단 접속함용 고무 슬리브(10)에 케이블을 삽입하고, 상기 종단 접속용 고무 슬리브(10)가 안착된 후 정해진 위치에 두 번째 슬리브를 삽입하며, 도체에 커넥터(40)를 장착하고 개스 터미네이션(gas termination)에 장착하여 전기적 시험을 실시하게 되는 것이다.Lubricate the cable and sleeve, insert the cable into the rubber sleeve 10 for the termination box, insert the second sleeve in the fixed position after the rubber sleeve 10 is seated, and connect the connector 40 to the conductor. ) And then to gas termination to perform an electrical test.
