Embodiment Construction
[0023] In order to make the purposes, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, but not all of them. example. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present invention.
[0024] At present, in the related art, electric boilers (also known as "thermoelectric furnaces", usually including direct and regenerative electric furnaces) are usually connected to a power supply through a contactor or a short-circuit. Take the contactor as an example, such as figure 1 As shown, a load switch is also connected between the contactor and the power supply, and the load switch can ...

The invention provides an electric boiler system and an electric boiler control method. The controller generates a first operation signal based on the preset startup parameters and the rated parameters of the electric boiler; the power regulating device generates the first operation signal based on the first operation signal and the voltage provided by the power supply Signal to output the power supply voltage to the electric boiler so that the electric boiler operates according to the starting parameters. The invention sends an operating signal to the power regulating device through the controller, so that the power regulating device can adjust the power supply voltage when the electric boiler is started, thereby reducing the impact on the power grid when the electric boiler is started, and improving the safety of power consumption.
Description
technical field [0001] The invention relates to the technical field of automatic control, in particular to an electric boiler system and an electric boiler control method. Background technique [0002] In the related art, a circuit breaker or a contactor is usually used to control the startup or shutdown of the electric boiler; however, in this method, when the electric boiler is connected to start or shut down, a huge instantaneous voltage change occurs, which makes the power grid connected to the electric boiler shock. , resulting in operating overvoltage, resulting in line harmonics and other problems. SUMMARY OF THE INVENTION [0003] In view of this, the purpose of the present invention is to provide an electric boiler system and an electric boiler control method, so as to reduce the impact on the power grid when the electric boiler is started, and improve the safety of electricity consumption. [0004] In the first aspect, the embodiment of the present invention pro...
