Today, electrical panels are one of the main elements of industrial and residential units. A switchboard is a usually closed compartment where electronic, automation or industrial electrical equipment can be installed. The group of electrical industry designers, the researcher, according to the project conditions and technical and control philosophy maps, designed and built automation and industrial switchboards. shows Contact the sales department for advice. The functions of the panels are: manual or automatic control of an industrial process, distribution of electricity between equipments and correction of the power factor. Our discussion here is related to low pressure panels or LV panels. Several different categories can be suggested for different types of electrical panels:
The first category is based on the type of panel operation, which is as follows:
1-PLC boards that are used to control an industrial process. 2- Boards that are used only to control AC or DC motors and include drives, contactor control circuits and motor controller circuits that are also in the shape of a star triangle. 3- Distribution boards that are created to distribute electricity and actually distribute current between different industrial equipment. 4- Power factor correction boards, which are known as capacitor bank boards. Of course, several of the above items may be placed together in a panel set.
The second category can be determined based on the installation location of the board. The types of boards in terms of installation location are:
Indoor: Indoor signs, these signs are installed in a closed space, such as inside a workshop or a residential building. :outdoor outdoor signs that are installed outdoors.
The panels based on the structure and appearance are:
1-Metal Enclosed: Panels are fully enclosed enclosures in which the equipment is installed and are divided into the following two types:
A- metal clad: In this panel, the different compartments of the key, bus bar, cable head and LV are separated.
B- Compartment Type: In this type of panels, different compartments are not separated from each other.
2- Sliding panels: the easier service of these panels and their higher safety have made them widely used in the electrical industry. These boards are usually made in two forms (MCC motor control board) and central power board that feeds MCC boards.
Understanding the equipment used in power boards:
In low pressure switchboards, a series of common equipments are used, familiarity with which is essential for a switchboard specialist. These equipments include: Contactor: an electromechanical device for disconnecting and connecting three phases: the way to connect the contactors to each other depends on the type of startups, either direct startup, or star-delta.
