Electric heating electromagnetic boiler can be used in various industries. As a manufacturer, we often hear some customers call and say that coil heating will occur when installing its electromagnetic heater. Now let's talk about the reason why the coil of the electric heating electromagnetic boiler is heated
First, the problem of matching coil and power of electric heating electromagnetic boiler the size of wire diameter and power should match. If the power is too large and the wire diameter is too small, it will lead to the problem of overload of wire diameter and flow, that is, the coil will burn. For example, it's enough for a 50KW machine to use 25mm2 from the calculation method, but in practical application, the coil will generate a lot of heat. Generally, we will choose a larger wire diameter and use a 35m2 wire, so that the wire diameter can be guaranteed not to burn.
II. The types of electromagnetic coils are commonly used in the market, such as high-temperature wire, high-frequency wire, high-temperature high-frequency wire. Different types of coils are selected in different occasions. With the same wire diameter, the overload capacity of high-temperature high-frequency wire of high-frequency wire is stronger than that of high-temperature wire.
Third, the production of induction electromagnetic coil in the production of electromagnetic induction coil, the winding method of the coil is also very important.
1. Many customers often twist the wire when winding, bending the wire diameter, which often damages the oneness of the wire diameter and reduces the over-current capacity, thus making the wire diameter hot.
2. The tightness between the coil and the coil. When winding, the coil and the coil shall not be close to each other, and the coil shall be separated by 3 mm at least, which is conducive to the heat dissipation of the coil.
