Electric heating tube wiring method and storage method, electric heating tube wiring, electric heating tube wiring is a problem that many customers find headaches. If the power is connected incorrectly, the electric heating tube will not heat up, and the electric heating tube will burn out if the power is too high. So how should the electric heating tube be wired and stored? The following is a detailed explanation for everyone.
We have 4 normal wiring methods:
1. Series connection: when connected in series, the power supply voltage of the electric heating tube is equal to the sum of the voltage of a single electric heating tube.
2. Parallel connection: When in parallel, the power supply voltage of the electric heating tube is equal to the voltage of a single electric heating tube.
3. Delta wiring method: The delta wiring method is normally used when 3 electric heating tubes or a multiple of 3 electric heating tubes are connected together. Its phase voltage is equal to the total voltage.
4. Star connection method: The star connection method is also used when 3 electric heating tubes or a multiple of 3 electric heating tubes are connected together. Its phase voltage*√3 is equal to the total voltage.
The cause of electric heating tube leakage, pay attention to the use of electric heating tube. On the other hand, electric heating tube may be caused by improper use. Therefore, the storage and use of electric heating tube should pay attention to the following points:
1. The storage location of the electric heating tube must be kept dry and proper insulation resistance. If the insulation resistance of the storage environment of the electric heating tube is found to be too low during use, it can be used after being restored by low-voltage power. The electric heating tube should be properly fixed before use, and the wiring part should be placed outside the insulation layer, and avoid contact with corrosive, explosive media and water.
2. Magnesium oxide at the outlet end of the electric heating tube is easily contaminated due to the infiltration of impurities and moisture. Therefore, pay attention to the state of the outlet end of the electric heating tube during operation to avoid leakage accidents caused by this.
3. When the electric heating tube is used to heat easily meltable metals or solid nitrate, paraffin, asphalt and other materials, the heating material must be melted first. At this time, the external voltage of the electric heating tube can be reduced, and the rated voltage will be restored when the melting is completed. In addition, when heating nitrates and other explosive-prone materials with electric heating tubes, safety measures must be fully considered.
4. When the electric heating tube is used for air heating, pay attention to the uniform arrangement of the electric heating tube. The advantage of this is to ensure that the electric heating tube has a relatively sufficient and uniform heat dissipation space, and ensure the fluidity of the air as much as possible, and improve the heating of the electric heating tube efficient.
5. When the non-standard electric heating tube is used for liquid or solid metal heating, the electric heating tube leaks the cause. Pay attention to the use of the electric heating tube. The electric heating tube must be completely placed in the object to be heated, and no electric heating tube is allowed to burn. After the electric heating tube is used, if there is scale or carbon on the outer metal shell, it must be removed in time to avoid affecting the heat dissipation performance and service life of the electric heating tube.
The above is the entire content of the electric heating tube wiring method and storage method shared today. The use of the electric heating tube needs to be more careful, especially the electric heating tube used in the home. The heating rod is an electric heater with a higher risk factor.
