What is the difference between 220v and 380v? As a heating element, the electric heating tube is also the electric heating tube serving as the heating body in the equipment we apply. However, we need to pay attention to and understand the difference between 220v and 380v of electric tubular heater pipe and their wiring methods. The following JINGWEI Electric small edition explains the difference and nature of the two in detail.
What is the difference between 220V and 380V heater:
The stainless steel heating tube has 380V and 220V, and how to use it depends on the specific situation of the equipment. The current of 380V electric heating tube is smaller than that of 220V electric heating tube under the condition of uniform power, that is to say, the current of 1WK 380electric heating tube is 2A. The current of 1WK 220V electric heating tube is about 4.5. The 380electric heating tube needs a three-phase power supply. So when you’re choosing a wire. Something thinner will do. 220V electric heating tube in the selection of wire. It is possible to be thicker, but the number of wires needs to be less than 380, and it can be said that each has its own strengths.
380V and 220Velectric heating tubes have the same heating efficiency under the same power. The security is the same. 380v coil is used more in the previous electronic control system, direct two-phase power supply can have phase-off protection function, and now promote safe electricity, the use of isolation transformer to provide control power supply, the basic use of 220v control power supply on ordinary equipment, and 110v is generally used as the machine tool electrical control power supply voltage level.
The three-phase motor has a difference of 120 degrees within 360 degrees of one electric cycle and is evenly distributed; Unidirectional motor is actually two phases, one phase is the power fireline, the other phase is the hysteresis 90 degrees voltage generated by the fireline capacitor, in a 360 degrees electrical cycle, the two differences are 90 degrees, uneven, asymmetrical, so the performance and stationarity of the three-phase motor is much better than that of the unidirectional motor. The single-phase motor not only has poor performance, low power factor, but also interferes with the power grid return, which is why the TV has a snowflake point when the hair dryer is opened. In high-power, torque, speed control requirements are relatively high occasions, only three-phase motors.
Electric heating tube220V and 380V difference:
1, 380v voltage is the voltage between two phase lines, generally used in power demand and other large capacity electrical appliances; The 220v voltage is the voltage difference between a phase line and a neutral line, which is generally used in lighting and small electrical appliances.
2, 380 is generally suitable for control of three-phase motors and other electrical equipment that does not allow the lack of phase, generally take A,C phase. A phase fault occurs in 2/3 of the possible magnet release. It is easy to check the fault with a pen; The 220′s control is generally suitable for individual power collection. Multiple shared. The load is not associated with the control. Use a pen to check the fault generally.
