终端配电系统选择性保护要求与SMCB的发展(续)

Requirement of Selective Protection in Terminal Power Distribution System and Development of SMCB

从终端配电系统选择性保护要求的现状出发,对于终端配电系统选择性保护提出了具体的要求,并将SMCB作为实现全电流范围选择性保护最为关键的元件。同时,结合目前国内外现状,从SMCB选择性保护原理与标准、产品涉及的关键技术及现有产品的主要特点与技术参数、典型应用方案、技术发展与应用前景等几个方面阐述了SMCB作为终端配电系统关键元件的必要性。最后指出SMCB具有广阔的发展前景。

Specific requirement of selective protection in terminal power distribution system was proposed from the current situation of selective protection requirement in terminal power distribution system,and took SMCB as the most important element of selective protection in the range of total current. Meanwhile, combined with the current situation of home and abroad, from several factors like the SMCB selective protection principle and standard, product＇s key technology and main characteristic and technical parameter of current product, typical application scheme,technology development and application prospect,the necessity that the SMCB was used as the key element in terminal power distribution system was expounded, and at last it was pointed out that SMCB had great development prospect.
