Electric heating tube 220v electric stove wire wiring diagram, electric stove wire as a kind of heating element, its power is also very high, electric stove wire electric heating is common in kettles, hair dryers and electric heating equipment, electric heating wires mainly include iron chromium aluminum alloy electric stove wire and nickel chromium There are two major types of alloy electric furnace wires. The maximum task temperature of the heating design of the electric furnace wire can reach 850℃. There are still many people who do not understand the wiring of the 220v electric furnace wire. The following electric heating tube manufacturers explain the wiring method for everyone.

220v electric heating tube electric stove wire wiring diagram
electric furnace wires mainly include iron-chromium-aluminum alloy electric furnace wires and nickel-chromium alloy electric furnace wires. The former is an alloy material with ferrite structure, and the latter is an alloy material with austenite structure. In addition, there are some special-purpose electric heating alloy wires such as tungsten wire, molybdenum wire and so on. It is characterized by high temperature resistance, fast heating, long service life, stable resistance, small power deviation, uniform pitch after stretching, and bright and clean surface. It is widely used in small electric furnaces, muffle furnaces, heating and air conditioning equipment, various ovens, electric heating tubes and Household appliances, etc.
220v electric heating tube electric furnace wire wiring method
method one:
One, 3-phase 4-wire is composed of 3 phase wires, that is, 3 live wires and a neutral wire. Just connect a live wire and a neutral wire.
2. In the case of a 3-phase 3-wire system, 2 phase wires (live wires) or 3 live wires must be used for conversion through a transformer.
Three. Of course, there is another one that is connected to 2 live wires (380V) when using the welding machine, then as long as the 2 wires are connected to the 220 wire of the power input terminal, it will be 220V. These are safe practices.
Fourth, there is another way that is not very safe (it is not recommended to do but just discuss how to change 380V to 220V) is to connect a ground wire, and you can get 220 when you take a phase wire and connect the electrical appliance between the phase wire and the ground wire. Power supply. Of course, this is not very safe. If the ground wire is pulled out, it will become a hot wire.
Method Two:
Three identical electric heating tubes, connected in a star shape. That is, one connector of three heating wires is connected in parallel, no N wire is required, and the other three connectors are connected to UVW.
Method 3:
The load of the three-phase power supply should be balanced as much as possible. Therefore, the most preferred wiring method for connecting 12 220V heating tubes to the three-phase 380V power supply is a star connection of four as a group. In order to ensure that the individual heating tubes are damaged, the phase voltage will be abnormal. The neutral point should be connected to zero.
How to connect the electric stove wire when it is broken?
1. To ensure good contact, you can deal with it like this: first polish the joint of the electric furnace wire clean, and then wrap the lead (usually copper wire) on the joint, and wind it a few more times.
2. If it is less than 2.5, it is recommended that you replace it with a new one, otherwise you can use A402 electrode for welding.
3. The length of the electric furnace wire is different when it is subjected to different voltages. The length of the coil can be shortened, which is also conducive to heat concentration; the collision of the coil and the coil is the same as the above, and it is easy to fuse at high temperature.
