一种变压器智能过载联切装置
摘要：
本发明公开一种变压器智能过载联切装置，包括主处理模块，所述主处理模块的输入端连接有交流输入变换模块和测温模块，主处理模块的输出端与输出模块相连，人机对话模块通过CAN通信模块与主处理模块相连，所述测温模块与变压器相连，用于测量变压器油温，交流输入变换模块的输入端与变压器高压侧及负荷线电流互感器的二次侧相连，用于测量变压器高压侧及负荷线的电流。本发明所述的变压器智能过载联切装置除采用变压器高压侧过电流分轮切负荷外，还采用变压器顶层油温和热点温度判别变压器的过负荷状况，从而分轮选择负荷切除以消除变压器的过负荷状态，以提高电力系统的安全稳定运行水平。
摘要（英）：

The invention discloses a transformer intelligent overload combined cut-off apparatus. The apparatus comprises a main processing module, the input end of the main processing module is connected with an AC input transformation module and a temperature measuring module, the output end of the main processing module is connected with an output module, a man-machine dialogue module is connected with the main processing module through a CAN communication module, the temperature measuring module is connected with a transformer for measuring the oil temperature of the transformer, and the input end of the AC input transformation module is connected with the high-voltage side of the transformer and the secondary side of a load line current transformer for measuring currents of the high-voltage side of the transformer and a load line. According to the transformer intelligent overload combined cut-off apparatus, overcurrents at the high-voltage side of the transformer are employed for cutting off a load by turns, and the overload condition of the transformer is also determined by use of the oil temperature of the transformer and a hot-spot temperature, so that the load can be selected and cut off by turns for the purposes of eliminating the overload state of the transformer and improving the safe and stable operation level of a power system.
