Electrical heating tube protection control system of electrical-heating steam generator

The utility model discloses an electrical heating tube protection control system of an electrical-heating steam generator. The electrical heating tube protection control system comprises a steam generator, wherein a water level probe is arranged in the steam generator, the water level probe is connected with a water level probe interface (X2) of a PLC (programmable logic controller), a water feeding pump for feeding water to the steam generator is connected with an interface (Q1) of the PLC through a direct-current (DC) solid-state relay, and an electrical heating tube of the steam generator is connected with an interface (Q2) of the PLC through a triphase solid-state relay. The electrical heating protection control system is reasonable in structure, can effectively protect the electrical heating tube from being damaged, so as to greatly save production cost and improve efficiency.
