变压器风冷控制柜采用进口继电器,采用独特的电机保护线路,任意一台电机出现故障时,系统只切除故障电机,其余风机电机正常运行,提高了风冷控制装置在高温季节的冷却效率,克服风冷装置任意一台电机故障必须切除整组风机的缺点。可编程控制箱可按时间设定启动多组风冷/冷却器,检查井钢模具 隔离墩模具 隔离墩钢模具 流水槽模具 U型槽模具 螺杆启闭机 卷扬式启闭机 铜雕佛像 可避免同时启动产生的冲击电流;同时可以实现工作、辅助、备用之间的自动切换,充分使用每台风冷/控制器,延长电机的使用寿命。另也可以根据用户的特殊要求灵活修改逻辑程序。可编程控制器控制箱可以通过通讯接口与显示终端和打印机等外设相连。及时将冷却器的运行情况反映到控制室,便于监视冷却器的运行情况,及时维护。
The transformer air cooling control cabinet adopts imported relay and unique motor protection circuit. When any motor fails, the system only cuts off the faulty motor, and the other fan motors operate normally, which improves the cooling efficiency of the air cooling control device in high temperature season and overcomes the disadvantage that the whole group of fans must be cut off when any motor of the air cooling device fails. The programmable control box can start multiple groups of air cooling / coolers according to the time setting, which can avoid the impulse current generated by simultaneous startup; At the same time, it can realize automatic switching between working, auxiliary and standby, make full use of each air cooling / controller, and prolong the service life of the motor. In addition, the logic program can be modified flexibly according to the special requirements of users. The PLC control box can be connected with peripheral devices such as display terminal and printer through communication interface. The operation of the cooler shall be reflected to the control room in time to facilitate the monitoring of the operation of the cooler and timely maintenance.
