摘要
变电站中的风冷控制系统对变压器的散热至关重要,风机的启停依据变压器的运行温度与设定的时间间隔。以单片机为主控器设计了一种智能时间继电器,具有四种工作模式,每种工作模式的延时范围可在一定范围内任意调节,经Proteus仿真验证,该系统运行可靠,具有一定的应用价值。
The air cooling control system in the substation is crucial to the heat dissipation of the transformer.The start and stop of the fan is based on the operating temperature of the transformer and the set time interval.A kind of intelligent time relay is designed with a single chip microcomputer as the main controller,which has four working modes.The delay range of each working mode can be adjusted arbitrarily within a certain range.The Proteus simulation shows that the system operates reliably and has certain application value.
