交直流电源串扰预控仪表
摘要：
本实用新型公开了一种交直流电源串扰预控仪表，包括：第一电流采集通道、第二电流采集通道、处理器和继电器；其中：第一电流采集通道采集第一路电流，并将采集的第一路电流发送至与其连接的处理器；第二电流采集通道采第二路电流，并将采集的第二路电流发送至与其连接的处理器；处理器与所述继电器连接，判断接收到的第一路电流和第二路电流是否均为直流电流，且大于门槛值，若是，则控制继电器导通，将第一电流采集通道和第二电流采集通道短接；若否，则控制继电器保持断开状态，第一电流采集通道和第二电流采集通道不短接。本实用新型能够有效避免交直流串扰事故的发生，保证了检修的安全与质量。
摘要（英）：

The utility model discloses an AC/DC power supply crosstalk precontrol instrument, comprising a first current collection channel, a second current collection channel, a processor and a relay. The first current collection channel collects current of a first way and sends the current of the first way to the processor connected with the first current collection channel. The second current collection channel collects current of a second way and sends the current of the second way to the processor connected with the second current collection channel. The processor is connected with the relay and determines that whether or not the current of the first way and the current of the second way are direct current and larger than a threshold value. If yes, the relay is controlled to be connected, and the first current collection channel is shortened to the second current collection channel. If not, the relay is controlled to maintain a disconnected state, and the first current collection channel is not shortened to the second current collection channel. The AC/DC power supply crosstalk precontrol instrument effectively prevents AC/DC crosstalk accidents and guarantees safety and quality of overhauling.
