Abstract

The fuse has based its long preeminence on electrical systems for its reliability and relative simplicity, due to follows well known physical principles. The complexity of the today distribution electric circuits, currently requires tools that provide intelligence, with which the "Smart Grids" are constituted. The fuse, in order to maintain its presence in low and medium voltage networks, must introduce characteristics that modern switches already possess, such as: remote operation, telemetering, automatic reconnection, directionality, adaptability, etc. Such improvements should not jeopardize the breaking capacity and reliability of the fuse. So far, some improvements have been introduced, many others are yet needed. A historical survey of the fuse previous designs tending to such objectives is presented. The improvements studied and in some cases already implemented commercially are described. It concludes in the need to recreate, update and improve the fuse, in order to comply with the requirements of intelligent distribution systems.

分布式发电智能电网现代保险丝的必要特性

由于遵循众所周知的物理原理，保险丝长期以来一直以其可靠性和相对简单性而在电气系统中占据主导地位。当今配电电路的复杂性，目前需要提供智能的工具，“智能电网”就是用这些工具构成的。为了在低压和中压网络中保持其存在，保险丝必须引入现代交换机已经具备的特性，例如:远程操作、遥测、自动重接、方向性、适应性等。这种改进不应危及熔断器的分断能力和可靠性。到目前为止，已经引入了一些改进，但还需要许多其他的改进。本文对以往的引信设计进行了历史回顾，以达到这一目的。介绍了已研究的改进措施，并在某些情况下已在商业上实施。最后提出需要对熔断器进行改造、更新和改进，以满足智能配电系统的要求。
