Abstract

Due to the increasing demand for underground installation of ground equipment, KEPCO has been researching the installation of Underground Compact Distribution Stations (U-CDS). To install and operate U-CDS in the distribution system, it is necessary to establish relevant standards and design and operation criteria. Therefore, this paper discusses the test method of IEC 62271-202 to establish its standard. This standard mainly comprises dielectric tests, temperature rise tests, short-time/peak current tests, and internal arc tests. However, each electrical distribution equipment has already been tested for dielectric, short-time current, internal fault arc, and temperature rise tests. Since U-CDS requires all equipment to be gathered in one place and operate safely, it is necessary to test the interconnections. As a result of the tests, some tests satisfied the standards, but others did not. Since these tests have not been performed before, additional research on the standards and test methods will be needed.

包括配电设备在内的地下建筑电气性能验证研究

由于对地面设备地下安装的需求不断增加，韩国电力公司一直在研究地下紧凑型配电站（U-CDS）的安装。为了在配电系统中安装和运行 U-CDS，有必要制定相关标准以及设计和运行准则。因此，本文讨论了 IEC 62271-202 的测试方法，以制定其标准。该标准主要包括介电测试、温升测试、短时/峰值电流测试和内部电弧测试。然而，每台配电设备都已进行了介电测试、短时电流测试、内部故障电弧测试和温升测试。由于 U-CDS 要求所有设备集中在一处并安全运行，因此有必要对互连进行测试。测试结果表明，有些测试符合标准，有些则不符合。由于以前没有进行过这些测试，因此需要对标准和测试方法进行更多的研究。
