一种时间继电器和断路器三相不一致保护电路以及断路器
摘要：
本申请公开了一种时间继电器，所述时间继电器的工作模块包括并联的第一至第三工作模块，其中每个工作模块具有两个控制节点，该三个工作模块节点之间通过“三选二”逻辑形成三条支路，当其中某个工作模块失效或误动作时其他两个工作模块的节点形成的支路仍可继续按照预设定延时可靠动作，从而增强了继电器的可靠性。
摘要（英）：

The application discloses a time relay. The working modules of the time relay comprise first, second and third working modules which are connected in parallel. Each working module comprises two control nodes. Three branches are formed among the nodes of the three working modules via the logic of "selecting two from three". When a certain working module fails to work or operates falsely, the branches formed by the modes of other two working modules can still reliably operate continuously according to the preset time delay so that reliability of the relay is enhanced.
