Introduce the requirements for the electric drum junction box

When using an electric drum, it needs to be connected. At this point, a junction box is needed. The junction box is mainly used to connect power lines and equipment circuits, so its use and installation have certain requirements. Below is a detailed introduction to the regulations it should comply with.
For three-phase motors, for electric rollers with a power of less than or equal to 3kW, the voltage is 380V when using a Y-shaped connection, and 220V when using a triangular connection. When the motor power is equal to or greater than 4kW, the voltage is 380V when using a triangular connection, and 660V when using a Y-shaped connection. For single-phase or three-phase motors with a power of less than 1kW, sometimes for installation convenience, a junction box is not used, and the motor leads are directly connected to the power line.
When the power is high, there is a thermal protector in the stator winding of the motor. If the electric drum is equipped with electromagnetic braking, the terminal layout in the junction box will be very complex. The junction box comes with a wiring diagram, and users can connect according to the diagram.
3. The junction box of the electric drum should comply with the provisions of GB3836.1-83 "General Requirements for Explosion proof Electrical Equipment for Explosive Environments" and GB3836.2-83 "Explosion proof Electrical Equipment for Explosive Environments - Explosion proof Electrical Equipment" d ".
The electric drum junction box should comply with standards and regulations, so we will introduce it here. From the above introduction, we can know that the junction box is actually an important component, and its correct use is related to the safety of the equipment. So, it is important to pay attention to mastering the correct methods during use.
