一种新颖的储能型剩余电流报警附件的设计

Design for Novel Energy Storage Type Residual Current Alarm Accessory

剩余电流报警附件能使剩余电流动作断路器在进行剩余电流保护的同时又兼有剩余电流信号报警功能,但一般模块对电网工作电压要求较高,影响运行可靠性。介绍了一种与电网电压无特殊要求的储能型剩余电流报警附件,分析了设计思路过程及产品工作原理、结构特点等。

The residual current alarm accessory is an additional functional module added in the residual current circuit breaker,which can not only make the residual current circuit breaker protect the residual current but also provide a function of residual current signal alarm. However, the general module has a high requiremeul on power grid work voltage. Therefore ,the operation reliability is affected. This paper introduced a residual current alarm accessory of energy storage type ,which has no special requirement on the power grid voltage, and analyzed the design innovation process, working principle and structural characteristics of the product.
