As low tension control equipment, the control cabinet is used to control the cooling facility of transformer fan. It applies to transformer of various voltages for cooling purpose. The main parts are PLC(Depends on), motor protector, thermorelay, stainless steel cabinet, connecting terminal, humid controller and heater etc. The PLC collects data of transformer cooling facility and analyses it. It automatically controls the output thermorelay to affect each group transformer cooling facility. It is modularly designed and bears the characteristics of easy changing, strong expandability, easy maintenance, high security, long life, low maintenance cost, etc.
