劣化指示氧化锌压敏电阻器在《维规》中明确要求:“安装前测试,运用中免测试”。在实际运用中劣化指示防雷元件并非是氧化锌压教电阻器,而是氧化锌压敏电阻器和金属陶瓷二极放电管组合而成,此类防雷元件有劣化指示,但不测试确有一定的问题。对此类防雷元件的结构进行了分析,并提出了解决意见和建议。
Deterioration of zinc oxide varistor in the “Victoria Regulation” clearly requires: “pre-installation test, the use of free test ”. Degradation in actual use indicates lightning protection components are not zinc oxide pressure teach resistance, but the combination of zinc oxide varistor and cermet diode discharge, such a lightning protection device has deteriorated instructions, but does not test Have some questions. The structure of such lightning protection components are analyzed, and suggestions and suggestions are put forward.
