What is a powerboard?
Electricity systems are very large and broad networks. This system encompasses all wires and cables inside and outside the residential building, power plants, factories, all kinds of industrial and construction projects. Power systems for distribution and transmission also require a variety of equipment in addition to wiring. These equipment and wiring fall into a chamber called powerboard.
Get to know more with electrical panels
are electrical panels with electrical equipment inside. Building electrical control or industrial machines is very dependent on the performance of the inside panel equipment. In the past, many problems, including short circuits, easy access to equipment and environmental factors, caused life and financial risks. Also, the lack of electrical panels can damage a variety of equipment against moisture, rain, dust, animals and more. A compartment for electrical equipment was intended to prevent these events and provide more security.
There are many components such as fuses, fuses, relay, timer, contactor, power key and switch, transistor, wire and cable and more. Each of these components performs its own tasks. The presence of these electrical panels is essential for the safe transmission and distribution of electrical energy.
Introduction to the equipment in the power panel
Fuse : A device that has the task of protecting the circuit against overload and short circuit. As the current flows in the circuit, the fuse burns and cuts the electric current. This prevents damage to the rest of the equipment.
Faithful : This device is responsible for cutting power outages if the temperature rises. When the temperature rises too much, the fear cuts the current. Insights protect 3 -phase engines from overheating or overheating.
Miniature key : The task of this key, such as fuses, is to cut power in short circuits and overload, but the miniature key does not burn after disconnection and returns to the system again.
Thermal Key : These keys in the powerboard 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.
Flow leakage key (John's protective) : This key has the task of protecting humans from electrical shock or electricity. Immediately after leakage in the current, the life protective key enters and disconnects the circuit. Thus prevents the circuit against damage.
Signal Lights : Lights or lights that show the different parts of the panel are on or off.
Duct cable : These docks are coatings to protect the wiring of the inside panel. In fact, the cables are put into these docks. This way, in addition to maintaining safety, it gives the panel a more beautiful and beautiful appearance.
Medium pressure panel
These boards have a voltage current between 1 and 36 kV. Medium pressure boards are usually assembled in multi -cell form. These panels have various equipment, including current measuring transformers, bass, power keys, relay, ground separating keys, and more. These panels are generally divided into three categories:
Traditional Medium Pressure
اری Medium Sliding Pressure
Medium Pressure Compact
Low -voltage
The low -voltage power panel is one of the most common electrical panels available in residential buildings or small houses. Using these panels, the quality of the equipment is preserved and their life is extended. On the other hand, it saves your costs.
This device is placed on measurement, protection, control, regulator, marker, and so on. In this way, it controls all the mechanical and electrical connections of the building. The voltage level of these boards is usually less than 1000 volts. These electrical panels are divided into different types:
What is the use of electrical panels?
in large panels, instead of the internal wiring, they use the slice or bullion; Because in these boards the consumer flow is very high. Unlike wiring without a drop in voltage, the shine passes a very strong current. In general, electrical panels are widely used for use in the following locations:
Types of residential buildings to supply power consumption
