Exchanger device for transformer substation and fault warning method

The invention relates to an exchanger device for a transformer substation and a fault warning method. The exchanger device replicates and accesses a generic object-oriented substation event packet; when the exchanger device determines that the generic object-oriented substation event packet triggers an abnormal state event, the exchanger device generates an abnormal state event confirmation request and transmits the request to a corresponding upstream exchanger device; and when the exchanger device can not receive a ready response from the upstream exchanger device, a warning message is sent out. Therefore, the exchanger device can obtain the initial triggered abnormal state event rapidly and accurately and thus maintenance is carried out conveniently. 种适用于变电站的交换器装置及故障警示方法，交换器装置复制并存取通用目标导向变电所事件分组，当交换器装置判断通用目标导向变电所事件分组触发异常状态事件时，交换器装置生成异常状态事件确认请求并传送至对应的上游交换器装置，交换器装置未能从上游交换器装置接收就绪响应时则发出警示消息，藉此可以达成快速且准确的得知初始触发异常状态事件的交换器装置以便于维修的技术功效。
