| 摘 要： | 新型全绝缘高压喷射式熔断器是广泛应用在10kV架空配电开关柜的保护和开关设备,目前广泛采用的跌落式熔断器具有触头裸露、绝缘水平低、拉合操作有一定危险性等弊端,基于此,研发了适用于国内要求的熔断器,将绝缘防护性能和操作安全性均较常规的熔断器进行了较大改进,并按国内要求大幅提高了开断能力和耐压水平,可以拉合负荷电流,结合实际要求提出了全面的试验标准,并成功地通过了试验挂网运行。

| Abstract: | New fully insulated highpressure jet type fuses are widely used in lOkV overhead distribution switchgear pro tection and switching devices. Now widely used dropout fuse has some defects, which are exposed contacts, low insu lation level, a certain pull together operational risk and other defects. Based on these, research and development appli cable to domestic requirements fuses were made; The insulating protective performance and operational safety have greatly improved; In accordance with national requirements breaking capacity and voltage level significantly increased that can pull together the load current. Combined with the practical requirements the comprehensive test standards were given, and experiment network operation was successfully passed. |
