Data from power and command circuits is used to analyze electrical maps. All electrical circuits are composed of two parts: command and power. The power circuit is responsible for passing the main current of the consumer. To create various designs, it is very effective to use contactor in the control circuit. In general, the start-up and control circuits are divided into the following two parts:
Command circuit: This part of the control circuit is responsible for disconnecting and connecting the contactor. This is done by stimulating the contactor coil. Of course, you should know that the command circuit has no special relationship with the power circuit.
⭕️ Introduction to the equipment in the power panel ⭕️
Fuse
a device that protects the circuit from overload and short circuit. As the current in the circuit increases, the fuse burns and cuts off the electric current. This work prevents damage to the rest of the equipment.
🔻 Bimetal
This device is responsible for cutting off the power flow in case of temperature rise. When the temperature gets too high, the bimetal cuts off the current. Bimetals protect 3-phase motors from overheating.
🔻 Miniature switch
The function of this switch, like a fuse, is to cut off the electricity in case of short circuit and overload, but the miniature switch does not burn after cutting the current and returns to the system. returns.
Thermal switch
These switches in the electrical panel have the task of protecting electric motors against phase imbalance, overload, etc.
Contactor This equipment is very similar to the relay. The contactor is used for switching in the circuit.
🔻current leakage switch (life protector)
This switch has the function of protecting people from electric shock or electrocution. Immediately after creating a leakage in the current, the safety switch comes into action and cuts off the circuit. In this way, it prevents the circuit from damage.
🔻 signal light
are lights or lights that show whether different parts of the panel are off or on.
🔻 timer
The task of this piece is timing and time management to send signals at appropriate times.
🔻 PLC
is a control system that has the task of controlling and monitoring the system. This advanced system is programmable and checks the performance conditions of the equipment. This system reacts appropriately to disconnection and connection of the device according to the plan.
🔻 Cable Duct
These ducts are covers to protect the wiring of the equipment inside the panel. In fact, the cables are placed inside these ducts. In this way, in addition to maintaining safety, it also gives the panel a more compact and beautiful appearance.
Electrical switch
Using this switch, you can manually cut off or turn on the current. connected
