Surrounding environment such as humidity and dust level

Connect two 100V heaters in series for single-phase 200V voltage.

In situations where the power of two heaters is different, they cannot be used. In situations where heaters of the same power can be used. In addition, the insulation performance (voltage resistance) of the heater used for 100V cannot meet the specifications of the heater used for 200V, and it cannot be used in places outside the factory (generally personal use areas).

Three phase 200V electric heating tubes can be used for single-phase 200V voltage interpretation

The heater with triangular wiring method can also be used if the wiring method is changed. If the star wiring method is used, it cannot be used. Moreover, the plug-in and flange heaters that can be used for single-phase 200V are indicated in the catalog as "three-phase 200V (single-phase 200V)", and special specifications can be used by changing the wiring method. Please specify on the order.

Several wiring methods for electric heating tubes

In many cases, electric heating tubes require multiple heating tubes to be connected together and finally connected to the power supply, which involves issues with wiring methods. Let me introduce to you the most common wiring methods for heating tubes:

1. Tandem

Series connection is one of the basic ways to connect circuit components. Connect the circuit components (such as heating rods) one by one in sequence, starting and ending. The circuit formed by connecting various electrical appliances in series is called a series circuit. The current passing through each electrical appliance in a series circuit is equal. The total voltage is equal to the sum of phase voltages. 2. Parallel connection

Parallel connection is a type of connection between circuit components, characterized by connecting the heads of two components or devices of the same or different classes, and also connecting the tails. Usually used to refer to the connection method of electronic components in a circuit, that is, a parallel circuit. 3. Y-shaped connection method (star shaped connection method)

Star connection method is a wiring method between three-phase AC power supply and three-phase electrical appliances. Connect the ends, X, Y, and Z of the three windings of the three-phase power supply together to form a common point O, and lead out three end wires from the starting points A, B, and C. It is a system that is connected to an external power supply in a certain way by three sinusoidal power sources with the same frequency, equal amplitude, and a phase difference of 120 ° in sequence. Y-shaped connection method, the line current is equal to the phase current, and the phase voltage is equal to √ 3 times the line voltage.

4. Triangle connection method (corner connection)

The triangular connection method of three-phase electricity is to connect the power sources or loads of each phase in sequence, and lead out each connected point as the three phase lines of three-phase electricity. The triangle connection method does not have a neutral point and cannot lead out a neutral wire, so it only has a three-phase three wire system. After adding the ground wire, it becomes a three-phase four wire system. The three-phase electricity of the triangle connection method has a line voltage equal to the phase voltage, and a line current equal to √ 3 times the phase current.
