The power panel is a compartment for installing and wiring electrical or electronic equipment with the control keys and components of the display (voltage, current, frequency, power, casinus fi). Electric boards are also used to prevent electric shock from entering equipment users and protect equipment against environmental factors. In many cases, the power panel is made of a metal box or shelf that can be installed in electrical components and various controllers. In addition to protecting internal equipment, the shelf is installed to prevent unauthorized people from accessing and protecting employees at the electrical risks. But the electrical panel is not a box and is actually a set of electrical components that are connected to each other to distribute the electric current to the electrical equipment.
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.
The voltage boards are divided into three categories:
LV (low pressure) Panel: Voltage Low Voltage has less than 5 volts. Like: Building electrical panel. MV (Medium Pressure) Panel: Voltage of Medium Voltage is between 1 and 2V. Like: Some industrial electrical panels. HV Panel (High Pressure): High Voltage Panels have a higher voltage than medium pressure. Like: Panels of the control room.
The electrical panels are divided into three different groups based on the structure and type of design;
1. Fixed Power Panel (Metal Enclosed) 2. Sliding electrical panel (withdrawable) - "Metal Clad" powerboard - Power "Composition Type" Power Panel 3. Powerboard (Rack)
The power panel carrys an electrical equipment such as power and steering equipment: Energy control and distribution is done through the equipment. The safety chamber increases people with potential risks such as electricity or explosion. The chamber protects the electrical equipment against environmental factors.
Control and distribute energy
Panel components include the main compartment, keys, ground connection system and other protective and control equipment.
a) The main compartment or body is a one or more cells that protects the equipment mounted inside or on it. Depending on the needs and use of plastic, iron, or composite, this compartment is made. Each compartment has its own IP number, indicating its permeability to environmental factors.
b) Keys have the task of disconnecting and connecting the circulation flow and appear in different types in the panels.
c) In the connection system to the ground, all the cells of the panel are connected to the Earth's connection conductor and are responsible for the safety of the people against electricity.
Protect people
The power chamber prevents people from contacting the current carrier equipment, thereby reducing the risk of clogging. Protecting electrical equipment against environmental environmental factors and increasing temperature in the panel chamber are factors that can disrupt the function of the panel.
A) protection against water penetration
To protect the equipment in the chamber against water vapor, rain, flooding or immersing in water (submarines) different chambers with different IP ranges are used. The first digit of the IP number specifies the amount of water permeability to the chamber.
B) Protects against extreme temperatures
severe temperatures can damage or disrupt electronic equipment. Ventilation tools are usually used to prevent a sharp increase in the temperature inside the chamber. To design the ventilation system, it is necessary to consider the usual temperature fluctuations over the night, the geographical location of the installation location, and the heat caused by the activity of the electrical equipment inside the chamber.
Application of electrical panels
Regarding the applications of the power panel, it is used in equipment that protects electronic devices against the dangers of electrical current fluctuations, increase or decrease voltage, and other electrical shocks.
In order to properly monitor the electronic equipment, the electrical panels are used, which is usually displayed by the current, electrical power, frequency and voltage at any time.
Another use of the presence of the cut -offs, which are mostly used for users' safety, if the safety of electrical appliances for any reason may be risky, in the event of an accident, it can be rapidly cut off for electricity. Used the cutters. Another use of electrical panel is the control of current intensity, frequency and voltage is one of the most important tasks of a good and standard power panel.
