Construction and assembly
Electrical panel consists of various mechanical and electrical parts of measurement, control and protection equipment. This switchboard is a compartment, which electronic and electrical equipment is placed inside, and the electrical control of various industrial devices depends on the operation of the electrical equipment inside the electrical switchboard, in addition to protecting the electrical switchboard from electrical equipment, against environmental conditions from causing damage caused by fire. It prevents possible electric shock and explosion. Electrical panels are designed and manufactured in different types in terms of their applications and dimensions. From zero to one hundred, designing, manufacturing and assembling industrial electrical panels is a completely specialized matter and requires knowledge and high work experience. Therefore, it is recommended to leave the order for the manufacture and assembly of the electrical panel to the professionals of this profession.
Different types of electrical panels
In terms of voltage level, electrical panels are divided into two categories: low pressure electrical panels and medium pressure electrical panels, MV electrical panels or medium pressure electrical panels at the voltage level of 1 to 3 kV, including voltage and current measuring transformers, various equipment Various controls and power switches are made and can be provided mainly for industrial applications in fixed and movable (sliding) types. The LV switchboard, or the low pressure in the transformer post and the time to convert the current from high to low voltage, is effective for electrification in the building with equipment suitable for this voltage, such as measuring, control and protection equipment. The type of material for the construction of the weak pressure panel is designed and manufactured according to the standard dimensions and according to the environment of installation and placement of cast iron, iron in wall, standing, facing and built-in types.
Design of different models of powerboards
The electrical panel is classified according to the following models in terms of design and shape. fixed switchboard sliding switchboard (movable) Modular switchboard
Fixed electrical panel
Fixed electrical panel is mainly one of the most used panels in the electrical industry, which is made in wall and standing type and has control and monitoring equipment and telecommunication data.
Sliding electrical panel
This type of switchboard with high applications is usually more expensive than other switchboard models. The design of this switchboard is such that the user can access all the internal equipment of the switchboard and can visit all the control parts. This switchboard model is very effective in large and complex industries.
Modular electrical panel
The modular electrical panel is considered to be one of the most advanced panels, which is designed and built in the form of a stand and a screen. It is possible to access the equipment in this type of switchboard, and the user can access its various parts from the back and front of the switchboard.
Types of Power Panel Installation Models
There are two very common models in the placement and installation of electrical panels, which are as follows.
Standing switchboard: The main feature of the standing switchboard is its very strong body and insulation, which is widely used in harsh industrial environments.
Wall panel: wall panel is placed on the wall in the form of facing and built-in. This model of switchboard is suitable for use in spaces such as small workshops and buildings.
Equipment and devices in the industrial electrical panel
Fuse: A fuse is placed as a practical tool inside the electrical panel to protect the circuits during overload and short connections and is able to cut off the current when the current in the circuits increases and prevent damage to various electrical equipment. to do
Bimetal: The main function of this equipment is to cut off the electric current when the temperature rises, when the temperature increases too much, the bimetal cuts off the current. This practical equipment protects three-phase electric motors against high temperature.
Miniature switch: This type of switch, similar to a fuse, cuts off the current during short circuits and overloads, except that the miniature switch works again under normal conditions after the current is cut off.
Thermal switch: The main function of the thermal switch is to protect the electric motor accurately during overload and phase imbalance.
Contactor: This very practical and consumable equipment, which is mainly placed in the electrical panel, acts like a relay and is used to switch the circuit.
Life-saving switch: This equipment, also known as leakage current switch, protects people's lives during electric shock and electric shock. At the time of leakage in the current, this type of high distance switch cuts the circuit and prevents damage to the circuit.
Timers: This piece is suitable for managing and timing the sending of signals.
Signal light: This type of light is useful for showing whether different parts of the electrical panel are on or off.
Electric switch: by means of this switch, the current can be disconnected and connected manually.
