摘要:

现场运行中的新型环保气体环网柜,根据用户需求,其中三工位接地开关和主开关布置方式存在差异,为满足标准中关于接地开关须具有关合短路电流能力的要求,鉴于安规及国网环网柜标准化规定,对运行中环保气体环网柜进行抽检试验。通过接地开关关合电流试验回路、试验过程、国家标准要求、试验的技术指标、关合能力影响因素等几方面进行了阐述。试验表明具有下三工位接地开关的环保气体环网柜,经过优化设计后顺利通过接地开关短路关合试验,为现场运行提供依据。

Abstract:

According to the user's needs, the layout of the three position grounding switch and the main switch of the new environmental gas ring network cabinet in operation is different. In order to meet the requirements of the standard that the grounding switch must have the ability to meet the short circuit current, in view of the safety regulations and the national grid ring network cabinet standardization regulations, the environmental gas ring network cabinet in operation is sampled and tested. The several aspects such as the grounding switch closing current testing circuit, the testing process, the national standard requirements, the technical indicators of the test, and the factors affecting the closing ability are elaborated. The test results show that the environmental gas ring network cabinet with the lower three position grounding switch successfully passed the short circuit closing test of the grounding switch, which can provide a basis for on-site operation.

Key words: environmental gas ring network cabinet, grounding switch, closing of short circuit, contact, fusion welding
