Description

technical field [0001] The invention relates to the field of electric heating appliances, in particular to an adjustable-length intelligent electromagnetic heating device and a control system thereof. Background technique [0002] Electromagnetic heater is the most widely used heating method in the industrial field and civil equipment. It adopts electromagnetic heating technology. The electromagnetic induction heating technology is called IH (Induction Heating) technology for short. It is developed on the basis of Faraday's induction law. It is an application of Faraday's law of induction. [0003] Its essence is to use electromagnetic induction to generate eddy currents in the cylinder to heat the workpiece. It converts electrical energy into electromagnetic energy, and then converts electromagnetic energy into electrical energy. The electrical energy is converted into thermal energy inside the metal to achieve the purpose of heating the metal. Thereby eliminating the harm...

Problems solved by technology

[0004] When these electromagnetic heating devices are heating the pipeline, the length of the heating device is often not enough to effectively heat the long pipeline, which greatly reduces the practicability of the heating device; not only that, in the control system When working, the working power supply circuit needs to provide a stable working voltage. At this time, in order to reduce the cost, the current working power supply circuit adopts a conventional voltage regulator transistor for voltage stabilization output, but due to the lack of good and effective protection measures, As a result, the output voltage will fluctuate, which will affect the stability of the control system and reduce its reliability.
