Relay Array for Grid Connection

A relay array may connect an electrical device (e.g., an inverter, power converter, etc.) to a utility grid. Based on a detection of a power interruption or fault, the relay array may disconnect the electrical device from the grid to ensure safety or reduce damage to the electrical device or grid. The relay array may include one or more electromechanical relays (e.g., latching relays). A safety catch may prevent the latching relay(s) from changing states. The electrical device may be configured to facilitate removal of the safety catch once the ability to change states is desired. The latchingrelay(s) may also be supplied with a power pulse for changing a state of the latching relay(s). The power pulse may be provided by a power bank that may be maintained with power in case of a power interruption or fault. 一种继电器阵列可以将电气装置(例如，逆变器、功率转换器等)连接到公用电网。基于对功率中断或故障的检测，所述继电器阵列可以断开所述电气装置与所述电网的连接，以确保安全或减少对所述电气装置或电网的损坏。所述继电器阵列可包括一个或多个机电继电器(例如，闭锁继电器)。安全锁扣可以防止所述闭锁继电器改变状态。所述电气装置可被配置为在需要改变状态的能力时促进所述安全锁扣的移除。也可为所述闭锁继电器提供用于改变所述闭锁
