이렇게 MCC 만들면 허전압으로 생기는 현장 컴플레인 없앨수 있습니다

Today, we are discussing the Smoke Exhaust Fan (MCC). It is a fan that exhausts smoke to the outside when a fire occurs. The fire department transmits a fire signal to the MCC, which is configured to enable the smoke exhaust fan to operate automatically. Between the MCC in the machine room and a signal coming from somewhere far away, if the transmission distance is long, induced voltage is generated due to the capacitance between the wires and the ground, causing the MCC to malfunction. By applying DC voltage when sending the signal, the MCC can operate automatically with high reliability, without the influence of induced voltage. From control panel manufacturing to installation and repair. Real electricity applied in the field. If you accurately apply the electrical theories you already know to practical work, you too are an expert starting today.
