Triangular joints.

The triangle connection of three-phase electricity is to connect each phase power supply or load end to end in turn, and lead each connected point out as the three phase wires of three-phase electricity. There is no neutral point in the triangle joint.

It is also not possible to draw out a neutral wire, so there is only a three-phase three-wire system. When the ground wire is added, it becomes a three-phase four-wire system.

The question you asked is too unclear, the heating element voltage is 380V, which can be connected into a triangle type, and the heating element voltage is 220V, which can only be connected to a star type.

Is it three heating elements 6 terminals The following figure is the triangle connection. The black ones are three heating wires.

The three heating pipes are wired in a 380V triangle, which means that the head and tail of the three heating pipes are connected separately, and the three joints can be connected to the three-phase power supply respectively.

Triangle connection: The triangle connection method of three-phase electricity is to connect each phase power supply or load end to end in turn, and lead each connected point out as the three phase wires of three-phase electricity. The triangular connection has no neutral point and cannot lead to a neutral line, so there is only a three-phase three-wire system.

When the ground wire is added, it becomes a three-phase four-wire system.

If the rated voltage of the heating tube is 220V and the power of the three heating tubes is the same, one end of the three tubes can be connected together, and the other end of the three tubes can be connected with three phase wires.

If the three electric heating pipes can be connected to the triangle connection, the triangle connection of the motor should be separated from the end of the head, and the electric heating does not need to be divided. But one thing is that the rated voltage of the electric heating pipe is 380V, and if it is 220V, it can only be connected to Y.

There are two types of connections: star and triangle.

1. The general star connection method is simple, each group of three groups selects an interface to connect together, and the remaining three interfaces are connected to three live wires of three-phase electricity, and the zero line is grounded.

2. The triangular connection method is to connect the three heat pipes of the heating tube end to end, and the remaining two ends are connected to one and one fire.

Two connections:

1. Three double U heating tubes (six heads), head and tail are connected, and the fire wire is triangular connection;

2. The head is connected to the live wire, the tail is connected, or the zero line is connected to the star connection.

With the Y connection method, it is also said that one end of the three heating wires is connected together, and the other three ends are connected to the inlet wire of the three-phase wire.

Generally, it is a triangular joint. The three sets of heating pipes are connected end to end, and the connections are connected to three phases respectively.

Summary. Dear Kiss I'm glad to answer for you, my answer is as follows: The wiring method of the three-phase wire of the electric heating pipe of the rice cart is as follows:

The first triangular joint; First, separate the 3 heating tubes from the head and tail. For example, the header is: u1 v1 w1 and the tail is w2 u2 v2.

Connect U1 and W2, V1 and U2, and WL and V2 respectively and connect them to the three-phase power supply. This connection is called a triangular connection. The second type of connection is the star connection.

Dear Kiss I'm glad to answer for you, and my regretful answer is as follows: The three-phase wire wiring method of the electric heating pipe of the rice truck is as follows: the first laughing reputation is the positive triangle connection; First, separate the 3 heating tubes from the head and tail.

For example, the header is: u1 v1 w1 and the tail is w2 u2 v2. Connect U1 and W2, V1 and U2, and WL and V2 respectively and connect them to the three-phase power supply.

This connection is called a triangular connection. The second connection method is the virtual star connection.

Hello, I recommend that you find a professional to wire for you.

Career well! I don't know how many volts the heating tube is, how can I check it out.

Well, the normal one is 220, and the star level is 380, and the corner joint.

Now my new heating tube is well, newly connected, but it's not hot, it's too slow, is this heating tube 380 not 220?

1) The rated voltage of an electric heating tube is 220V, so when it only uses one, the power supply voltage it is connected to is 220V. The rated slag voltage of an electric heating tube is 380V, so when it only uses one, the power supply voltage it connects to is 380V. (2) The rated voltage of one heating tube is 220V, and the three heating pipes are connected to the power supply voltage of 220V in parallel, and the power supply voltage of 380V is connected by the star (Y-type) wiring method.

The rated voltage of one heating pipe is 380V, and the three are used together, and the power supply voltage of 2 phases of 380V is connected in parallel, and the power supply voltage of 380V is quietly connected with the delta wiring scale. Therefore, to distinguish whether the heating tube is 220 volts or 380 volts, we can determine the resistance value of a single heating tube, or judge the rated voltage of the heating tube according to the wiring method of the heating tube.

You can measure the resistance value to determine how many volts the heating tube is.

Here's how. The brightener voltage of the heating tube can be identified by the resistance value, and the resistance value can be determined by measuring the resistance value, and the power is multiplied by the resistance value to see whether it is 220V to the 2nd power or 380V to the 2nd power.

Summary. Dear, if you want to connect the 380V 3 heating pipes of the electric steamer, you need to understand the wiring method of the power supply and the wiring method of the heating pipe.

Dear, if you want to connect the 380V 3 heating pipes of the electric steamer, you need to understand the wiring method of the power supply and the wiring method of the heating pipe.

Power wiring method: the electric hidden bright posture steamer usually uses three-phase power supply, in which L1, L2, L3 are the three phase lines of the key spike, the stove is the zero line, and PE is the ground wire. Before wiring, you need to turn off the main power switch, confirm whether all the lines in the power cord are qualified, whether the power cord span is correct, whether the wires are tightly and firmly, and then wire.

Wiring method of heating pipe: Generally speaking, there are two wiring methods for heating pipes, direct wiring and socket wiring. 1.

Direct wiring: Insert the heating pipe head directly into the binding post hole, and then tighten it with screws. When the plug is inserted, you can use a screwdriver to press down on the metal piece next to the plug and insert the plug into the post hole.

2.Socket wiring: Insert the heating pipe head into the socket.

There are many types of sockets, and the choice should be made according to the specifications of the Gatan Shen heat pipe.

When wiring, it is necessary to wire according to the wiring diagram provided by Zhiye Ji, a spine manufacturer of hosiery equipment, connect the power supply to the power terminal of the electric steamer, and then connect the heating pipe to the heating pipe terminal. After the wiring is completed, check whether all the wiring is firm, and then turn on the power to test whether the device can start normally and heat up properly.

Hello dear, the connection method of the electric steamer 380v 3 heating pipes depends on the specific situation, the following is a common connection: 1Make sure the power switch of the steamer is turned off and disconnect the power supply of the brigade.

2.Open the lid of the steamer box and find the terminal block of the heating tube. Generally, there is a metal plate at the top or bottom of the inside of the steamer, and there is a terminal on it.

3.According to the model and specification of the heating pipe, check the wiring diagram or parameter table of the heating pipe in Tsaizhou, and find the L, N, and E wires at the end of the heating pipe. 4.

Connect the L, N, and E wires of the heating pipe and the L, N, and E wires of the power terminal with a single wire to confirm that the connection is secure. 5.Close the lid of the electrical box, turn on the power supply, turn on the power switch, and check whether the heater is working properly.

6.Note that the installation of the electric steamer requires professional operation, and it is highly recommended to ask a professional electrician to operate it.
