Study on System Design Scheme for Electrical Control Scheme of Boiler

Abstract:

The breeding plumbing boiler is a full automatic temperature adjustment system with double efficacy of winter heating and summer cooling, constituted by host, auxiliary engine, control system and plumbing pipes, etc. Intermediate between PLC output port and AC contactor is to achieve the isolation between weak current and strong current, enhance the reliability of the system. Two frequency changers are designed for the hardware of system. Frequency converter input power linked up front access air switch. Frequency converter input terminals main circuit switch and the three phase power through air connection, frequency converter main circuit output terminals connected to the contactor three-phase motor. It is proved by field experimental operation that the control system proposed not only can realize automatic control of boiler burning process efficiently, but also reduced energy consumption greatly and effectively improved the level of boiler control management.
