配电变压器失压主动报警装置研究

Research on the Active Alarm Device for Distribution Transformer

为及时发现和处理用户侧停电故障,研制一种基于用户侧配电变压器的失压主动报警装置。当发生配电变压器停电故障时,采集其出线侧电压电流信号,经过微控器分析处理,通过手机短信形式发布报警信息,实现用户侧停电的精准定位、快速响应。

In order to find out and deal with the blackout on the user side in time, an active alarming device based on the user side transformer voltage sag detection is proposed in this paper.When a blackout accident occurs, the device will output warning notice via SMS after analyzing the sampled information.The device can achieve precise locating and rapid response to the blackout on the user side minimizing the negative effect of the user outage.
